Each type of dissertation serves a different academic purpose and requires a unique approach and structure. In this article, we’ll take a look at these differences in detail, providing clear explanations and examples from a range of academic disciplines. By the end of this article, you should have a thorough understanding of the options available for your dissertation and be better prepared to select a path that aligns with your research goals and academic ambitions.

Remember, regardless of what type of dissertation you ultimately decide to pursue, best dissertation proofreading can make all the difference between a pass and a fail.

7 Types of Dissertation

Empirical Dissertations

So, let’s dive right in with empirical dissertations—arguably the most hands-on type of dissertation out there. If you’re studying a field like psychology, biology, or social sciences, you’re probably going to become very familiar with this approach.

What exactly is an empirical dissertation?

It’s all about gathering data. You’ll be conducting your own experiments, surveys, or observations, making this type extremely engaging (and a bit daunting). Essentially, you’re collecting new data from the world or from people, rather than relying on existing data from other studies.

The structure of an empirical dissertation is pretty straightforward but involves rigorous methodology. Typically, it will include an introduction to set up your SMART research question , a literature review to justify why this question needs answering, a methodology section that details how you’ve gone about your data collection, a results chapter presenting your findings, and a discussion that ties everything back to your research question and explores the implications.

This type of dissertation not only tests your ability to conduct research and analyze data but also challenges you to apply theoretical knowledge in practical scenarios. By the end of an empirical dissertation, you should not only have answers to your original questions but also a solid chunk of real-world experience under your belt.

Best suited to: Students who are ready to roll up their sleeves and get their hands dirty.

Theoretical Dissertations

Now, shifting gears, let’s talk about theoretical dissertations. If the empirical dissertation is the hands-on, muddy boots kind of research, the theoretical dissertation is its more contemplative, indoor cousin. Perfect for those of you in fields like philosophy, literature, or certain branches of sociology and psychology, where concrete data might not be the main focus.

What’s the deal with theoretical dissertations? They revolve around developing, exploring, or expanding on existing theories. Instead of collecting new data, you invest your time and effort studying existing research and theoretical frameworks to build an argument or propose a new theory or perspective on an old one.

The structure of a theoretical dissertation generally includes a comprehensive introduction where you lay out your thesis or theory, followed by a detailed literature review that supports and provides the foundation for your thesis. After this, you’ll move into a discussion or analysis section, where you critically analyze your thesis in the light of existing theories and literature. The aim here is to offer a fresh or refined perspective that contributes to the existing body of knowledge.

This type of dissertation is a test of your analytical skills and your ability to synthesize complex ideas into a coherent argument. It’s less about creating new paths and more about mapping the ones already laid out in new ways.

Best suited to: Students who love theory and thrive on crafting arguments.

Case Study Dissertations

Next up, it’s case study dissertations. This type of dissertation is especially attractive if you’re someone who loves storytelling with a purpose or is drawn to in-depth analysis of specific events, individuals, or organizations. It’s a favorite in disciplines like business, education, psychology, and social sciences, where a single case can lead to the development of new theories and concepts.

A case study dissertation involves an intensive investigation of a particular individual, group, organization, or event. You’ll get to the nitty gritty of the specifics, examining various aspects of the case to understand its implications and applications. This method allows you to apply theoretical concepts in a real-world context, providing rich insights that aren’t always accessible through broader surveys or experiments.

The structure of a case study dissertation usually starts with an introduction to the chosen case, followed by a literature review that sets the theoretical framework. You then proceed to a detailed methodology section explaining how you collected and analyzed your data. The core of your dissertation will likely be the case analysis chapter, where you dissect the case in relation to your research question. Finally, you’ll conclude with a discussion of how the case impacts the wider field and what new understandings it brings to the fore.

Best suited to: Those who are meticulous and have a keen eye for detail, a case study dissertation allows you to explore the intricacies of a specific example while contributing to broader academic debates.

Comparative Dissertations

Next up is the comparative dissertation. This type is tailor-made for the analytically minded who love drawing connections and distinctions between different elements. It’s particularly prevalent in fields like law, education, political science, and international relations, where understanding differences and similarities across cases, laws, or educational methods can provide critical insights.

Essentially, a comparative dissertation involves systematically comparing and contrasting two or more entities. These could be policies, theories, populations, or even historical periods, depending on your study area. The goal is to identify patterns or discrepancies that reveal underlying principles or suggest new interpretations of data.

The structure of a dissertation of this nature typically includes a dissertation abstract followed by an introduction that defines the entities being compared and poses your research question. This is followed by a literature review that frames the theoretical bases for comparison. The methodology section should clearly outline the criteria and methods for comparison, ensuring transparency and replicability. The subsequent chapters will then detail the comparative analysis, discussing each entity individually before bringing them together for a comprehensive comparison. Finally, the conclusion synthesizes the findings, highlighting the significance of the differences and similarities discovered.

Best suited to: Those who can juggle multiple themes and variables without losing sight of the overarching question, a comparative dissertation challenges you to remain objective and balanced in your analysis.

Project-Based Dissertations

Project-based dissertations are more practical in nature. This type of dissertation is particularly appealing if you’re inclined towards applying your theoretical knowledge to create something tangible or solve a real-world problem. It’s a common choice in fields like engineering, computer science, and applied arts, where the end product can be a piece of software, an engineering prototype, or a design project.

What makes a project-based dissertation stand out? It centers around a project that you will plan, execute, and manage through the duration of your dissertation process. This could involve designing a new gadget, developing a software program, or creating a marketing plan for a startup. The focus is on applying the skills and knowledge you’ve acquired through your studies to produce a project that has practical and theoretical implications.

The structure of a project-based dissertation generally includes an introduction to the project, its objectives, and its relevance to your field. Following this, you’ll provide a literature review that supports the theories and methodologies you intend to use. The methodology section should detail your project plan, resources, and the processes you will follow. The main body of the dissertation will describe the project development and implementation phases in detail. Finally, the conclusion will evaluate the project’s success, its impact, and potential future developments or applications.

Best suited to: The innovative and the practical, a project-based dissertation allows you to showcase your ability to deliver a concrete outcome that demonstrates your professional capabilities.

Narrative Dissertations

If you’re drawn to writing and storytelling, a narrative dissertation might be right up your alley. This type is particularly popular in fields such as creative arts, literature, and education, where personal narratives or creative elements can be used to explore and communicate complex ideas.

What does a narrative dissertation involve? It’s about crafting a dissertation that primarily uses narrative techniques to convey research findings or explore scholarly questions. This could mean writing in a first-person perspective, incorporating fictional elements, or structuring the dissertation like a series of interconnected stories or essays.

The structure of a narrative dissertation often deviates from the traditional format. It begins with an introduction that sets the stage for the narrative journey. The literature review might be woven into the narrative itself, providing contextual background as the story unfolds. The methodology section explains how narrative methods will be used to explore the research question. The main body is where the narrative takes center stage, presenting research through personal reflections, storytelling, or hypothetical scenarios. The conclusion then ties all narrative threads together, reflecting on the insights gained and their broader implications.

Best suited to: those who think and express themselves best through stories, a narrative dissertation allows you to engage with your topic in a deeply personal and creative way.

Systematic Review Dissertations

Systematic review dissertations are perfect if you’re keen on synthesizing existing research to draw comprehensive conclusions about a specific topic. This type is particularly valuable in fields like healthcare, psychology, and social sciences, where summarizing and evaluating existing studies can provide powerful insights and inform practice and policy.

A systematic review dissertation involves a rigorous and structured approach to reviewing literature. You’ll gather all relevant data from previously published studies to answer a specific research question. The focus is on transparency and reproducibility, employing predefined methods to minimize bias and provide reliable results.

The structure of a systematic review dissertation typically begins with an introduction that outlines the research question and its significance. This is followed by a methodologically detailed section that explains the criteria for selecting studies, the search strategy used, and the methods for data extraction and synthesis. The results section then presents a detailed analysis of the studies included in the review, often using quantitative methods like meta-analysis. The discussion interprets these findings, considering their implications for the field and any limitations. The conclusion suggests areas for further research and summarizes the contributions made by the review.

Best suited to: Those with a keen eye for detail and a systematic approach to research, a systematic review dissertation can significantly impact by clarifying and summarizing existing knowledge.

Methodological Considerations

Choosing the right type of dissertation is an important decision in your academic journey, and several factors should guide your selection. This section aims to help you navigate these choices, ensuring that the methodology and framework you choose align perfectly with your research goals, available resources, and time constraints.

First, consider your discipline’s requirements and norms. Different fields favor different types of dissertations, so understanding what is expected and respected in your area of study is crucial. Next, think about your own strengths and interests. Choose a dissertation type that not only meets academic criteria but also excites you and plays to your strengths, whether they lie in empirical research, theoretical exploration, practical application, or creative expression.

Resource availability is another critical factor. Some types of dissertations, like empirical and project-based, may require access to specific equipment, software, or locations, which can be a deciding factor. Time constraints are also essential to consider; some dissertations, particularly those involving extensive data collection and analysis, may require more time than others.

Finally, discuss your ideas with your advisor or mentor. They can provide valuable insights and feedback that can help you refine your choice and ensure that you are prepared to tackle the challenges ahead. With the right preparation and understanding of what each type of dissertation entails, you can make an informed decision that sets the stage for a successful and rewarding research endeavor.

The Top 3 Types of Dissertation Research Explained

Preparing for your doctoral dissertation takes serious perseverance. You’ve endured years of studies and professional development to get to this point. After sleepless nights and labor-intensive research, you’re ready to present the culmination of all of your hard work. Even with a strong base knowledge, it can be difficult — even daunting — to decide how you will begin writing.

By taking a wide-lens view of the dissertation research process , you can best assess the work you have ahead of you and any gaps in your current research strategy. Subsequently, you’ll begin to develop a timeline so you can work efficiently and cross that finish line with your degree in hand.

What Is a Dissertation?

A dissertation is a published piece of research on a novel topic in your chosen field. Students complete a dissertation as part of a doctoral or PhD program. For most students, a dissertation is the first substantive piece of academic research they will write. 

Because a dissertation becomes a published piece of academic literature that other academics may cite, students must defend it in front of a board of experts consisting of peers in their field, including professors, their advisor, and other industry experts. 

For many students, a dissertation is the first piece of research in a long career full of research. As such, it’s important to choose a topic that’s interesting and engaging.

Types of Dissertation Research

Dissertations can take on many forms, based on research and methods of presentation in front of a committee board of academics and experts in the field. Here, we’ll focus on the three main types of dissertation research to get you one step closer to earning your doctoral degree.

1. Qualitative

The first type of dissertation is known as a qualitative dissertation . A qualitative dissertation mirrors the qualitative research that a doctoral candidate would conduct throughout their studies. This type of research relies on non-numbers-based data collected through things like interviews, focus groups and participant observation. 

The decision to model your dissertation research according to the qualitative method will depend largely on the data itself that you are collecting. For example, dissertation research in the field of education or psychology may lend itself to a qualitative approach, depending on the essence of research. Within a qualitative dissertation research model, a candidate may pursue one or more of the following:

• Case study research
• Autoethnographies
• Narrative research 
• Grounded theory 

Although individual approaches may vary, qualitative dissertations usually include certain foundational characteristics. For example, the type of research conducted to develop a qualitative dissertation often follows an emergent design, meaning that the content and research strategy changes over time. Candidates also rely on research paradigms to further strategize how best to collect and relay their findings. These include critical theory, constructivism and interpretivism, to name a few. 

Because qualitative researchers integrate non-numerical data, their methods of collection often include unstructured interview, focus groups and participant observations. Of course, researchers still need rubrics from which to assess the quality of their findings, even though they won’t be numbers-based. To do so, they subject the data collected to the following criteria: dependability, transferability and validity. 

When it comes time to present their findings, doctoral candidates who produce qualitative dissertation research have several options. Some choose to include case studies, personal findings, narratives, observations and abstracts. Their presentation focuses on theoretical insights based on relevant data points. 

2. Quantitative

Quantitative dissertation research, on the other hand, focuses on the numbers. Candidates employ quantitative research methods to aggregate data that can be easily categorized and analyzed. In addition to traditional statistical analysis, quantitative research also hones specific research strategy based on the type of research questions. Quantitative candidates may also employ theory-driven research, replication-based studies and data-driven dissertations. 

When conducting research, some candidates who rely on quantitative measures focus their work on testing existing theories, while others create an original approach. To refine their approach, quantitative researchers focus on positivist or post-positivist research paradigms. Quantitative research designs focus on descriptive, experimental or relationship-based designs, to name a few. 

To collect the data itself, researchers focus on questionnaires and surveys, structured interviews and observations, data sets and laboratory-based methods. Then, once it’s time to assess the quality of the data, quantitative researchers measure their results against a set of criteria, including: reliability, internal/external validity and construct validity. Quantitative researchers have options when presenting their findings. Candidates convey their results using graphs, data, tables and analytical statements.

3. Mixed-Method

Many PhD candidates also use a hybrid model in which they employ both qualitative and quantitative methods of research. Mixed dissertation research models are fairly new and gaining traction. For a variety of reasons, a mixed-method approach offers candidates both versatility and credibility. It’s a more comprehensive strategy that allows for a wider capture of data with a wide range of presentation optimization. 

In the most common cases, candidates will first use quantitative methods to collect and categorize their data. Then, they’ll rely on qualitative methods to analyze that data and draw meaningful conclusions to relay to their committee panel. 

With a mixed-method approach, although you’re able to collect and analyze a more broad range of data, you run the risk of widening the scope of your dissertation research so much that you’re not able to reach succinct, sustainable conclusions. This is where it becomes critical to outline your research goals and strategy early on in the dissertation process so that the techniques you use to capture data have been thoroughly examined. 

How to Choose a Type of Dissertation Research That’s Right for You

After this overview of application and function, you may still be wondering how to go about choosing a dissertation type that’s right for you and your research proposition. In doing so, you’ll have a couple of things to consider: 

• What are your personal motivations? 
• What are your academic goals? 

It’s important to discern exactly what you hope to get out of your doctoral program . Of course, the presentation of your dissertation is, formally speaking, the pinnacle of your research. However, doctoral candidates must also consider:

• Which contributions they will make to the field
• Who they hope to collaborate with throughout their studies
• What they hope to take away from the experience personally, professionally and academically

Personal Considerations

To discern which type of dissertation research to choose, you have to take a closer look at your learning style, work ethic and even your personality. 

Quantitative research tends to be sequential and patterned-oriented. Steps move in a logical order, so it becomes clear what the next step should be at all times. For most candidates, this makes it easier to devise a timeline and stay on track. It also keeps you from getting overwhelmed by the magnitude of research involved. You’ll be able to assess your progress and make simple adjustments to stay on target. 

On the other hand, maybe you know that your research will involve many interviews and focus groups. You anticipate that you’ll have to coordinate participants’ schedules, and this will require some flexibility. Instead of creating a rigid schedule from the get-go, allowing your research to flow in a non-linear fashion may actually help you accomplish tasks more efficiently, albeit out of order. This also allows you the personal versatility of rerouting research strategy as you collect new data that leads you down other paths. 

After examining the research you need to conduct, consider more broadly: What type of student and researcher are you? In other words, What motivates you to do your best work? 

You’ll need to make sure that your methodology is conducive to the data you’re collecting, and you also need to make sure that it aligns with your work ethic so you set yourself up for success. If jumping from one task to another will cause you extra stress, but planning ahead puts you at ease, a quantitative research method may be best, assuming the type of research allows for this. 

Professional Considerations

The skills you master while working on your dissertation will serve you well beyond the day you earn your degree. Take into account the skills you’d like to develop for your academic and professional future. In addition to the hard skills you will develop in your area of expertise, you’ll also develop soft skills that are transferable to nearly any professional or academic setting. Perhaps you want to hone your ability to strategize a timeline, gather data efficiently or draw clear conclusions about the significance of your data collection. 

If you have considerable experience with quantitative analysis, but lack an extensive qualitative research portfolio, now may be your opportunity to explore — as long as you’re willing to put in the legwork to refine your skills or work closely with your mentor to develop a strategy together. 

Academic Considerations

For many doctoral candidates who hope to pursue a professional career in the world of academia, writing your dissertation is a practice in developing general research strategies that can be applied to any academic project. 

Candidates who are unsure which dissertation type best suits their research should consider whether they will take a philosophical or theoretical approach or come up with a thesis that addresses a specific problem or idea. Narrowing down this approach can sometimes happen even before the research begins. Other times, candidates begin to refine their methods once the data begins to tell a more concrete story.

Next Step: Structuring Your Dissertation Research Schedule

Once you’ve chosen which type of dissertation research you’ll pursue, you’ve already crossed the first hurdle. The next hurdle becomes when and where to fit dedicated research time and visits with your mentor into your schedule. The busyness of day-to-day life shouldn’t prevent you from making your academic dream a reality. In fact, search for programs that assist, not impede, your path to higher levels of academic success.

What is a thesis?

What is a dissertation, getting started, staying on track.

A thesis is a long-term project that you work on over the course of a semester or a year. Theses have a very wide variety of styles and content, so we encourage you to look at prior examples and work closely with faculty to develop yours. 

Before you begin, make sure that you are familiar with the dissertation genre—what it is for and what it looks like.

Generally speaking, a dissertation’s purpose is to prove that you have the expertise necessary to fulfill your doctoral-degree requirements by showing depth of knowledge and independent thinking.

The form of a dissertation may vary by discipline. Be sure to follow the specific guidelines of your department.

• PhD This site directs candidates to the GSAS website about dissertations , with links to checklists,  planning, formatting, acknowledgments, submission, and publishing options. There is also a link to guidelines for the prospectus . Consult with your committee chair about specific requirements and standards for your dissertation.
• DDES This document covers planning, patent filing, submission guidelines, publishing options, formatting guidelines, sample pages, citation guidelines, and a list of common errors to avoid. There is also a link to guidelines for the prospectus .
• Scholarly Pursuits (GSAS) This searchable booklet from Harvard GSAS is a comprehensive guide to writing dissertations, dissertation-fellowship applications, academic journal articles, and academic job documents.

Finding an original topic can be a daunting and overwhelming task. These key concepts can help you focus and save time.

Finding a topic for your thesis or dissertation should start with a research question that excites or at least interests you. A rigorous, engaging, and original project will require continuous curiosity about your topic, about your own thoughts on the topic, and about what other scholars have said on your topic. Avoid getting boxed in by thinking you know what you want to say from the beginning; let your research and your writing evolve as you explore and fine-tune your focus through constant questioning and exploration.

Get a sense of the broader picture before you narrow your focus and attempt to frame an argument. Read, skim, and otherwise familiarize yourself with what other scholars have done in areas related to your proposed topic. Briefly explore topics tangentially related to yours to broaden your perspective and increase your chance of finding a unique angle to pursue.

Critical Reading

Critical reading is the opposite of passive reading. Instead of merely reading for information to absorb, critical reading also involves careful, sustained thinking about what you are reading. This process may include analyzing the author’s motives and assumptions, asking what might be left out of the discussion, considering what you agree with or disagree with in the author’s statements and why you agree or disagree, and exploring connections or contradictions between scholarly arguments. Here is a resource to help hone your critical-reading skills:

http://writing.umn.edu/sws/assets/pdf/quicktips/criticalread.pdf

Conversation

Your thesis or dissertation will incorporate some ideas from other scholars whose work you researched. By reading critically and following your curiosity, you will develop your own ideas and claims, and these contributions are the core of your project. You will also acknowledge the work of scholars who came before you, and you must accurately and fairly attribute this work and define your place within the larger discussion. Make sure that you know how to quote, summarize, paraphrase ,  integrate , and cite secondary sources to avoid plagiarism and to show the depth and breadth of your knowledge.

A thesis is a long-term, large project that involves both research and writing; it is easy to lose focus, motivation, and momentum. Here are suggestions for achieving the result you want in the time you have.

The dissertation is probably the largest project you have undertaken, and a lot of the work is self-directed. The project can feel daunting or even overwhelming unless you break it down into manageable pieces and create a timeline for completing each smaller task. Be realistic but also challenge yourself, and be forgiving of yourself if you miss a self-imposed deadline here and there.

Your program will also have specific deadlines for different requirements, including establishing a committee, submitting a prospectus, completing the dissertation, defending the dissertation, and submitting your work. Consult your department’s website for these dates and incorporate them into the timeline for your work.

Accountability

Sometimes self-imposed deadlines do not feel urgent unless there is accountability to someone beyond yourself. To increase your motivation to complete tasks on schedule, set dates with your committee chair to submit pre-determined pieces of a chapter. You can also arrange with a fellow doctoral student to check on each other’s progress. Research and writing can be lonely, so it is also nice to share that journey with someone and support each other through the process.

Common Pitfalls

The most common challenges for students writing a dissertation are writer’s block, information-overload, and the compulsion to keep researching forever.

There are many strategies for avoiding writer’s block, such as freewriting, outlining, taking a walk, starting in the middle, and creating an ideal work environment for your particular learning style. Pay attention to what helps you and try different things until you find what works.

Efficient researching techniques are essential to avoiding information-overload. Here are a couple of resources about strategies for finding sources and quickly obtaining essential information from them.

https://students.dartmouth.edu/academic-skills/learning-resources/learning-strategies/reading-techniques

Finally, remember that there is always more to learn and your dissertation cannot incorporate everything. Follow your curiosity but also set limits on the scope of your work. It helps to create a folder entitled “future projects” for topics and sources that interest you but that do not fit neatly into the dissertation. Also remember that future scholars will build off of your work, so leave something for them to do.

Browsing through theses and dissertations of the past can help to get a sense of your options and gain inspiration but be careful to use current guidelines and refer to your committee instead of relying on these examples for form or formatting.

Know How to Structure Your PhD Thesis

• 4 minute read

Table of Contents

In your academic career, few projects are more important than your PhD thesis. Unfortunately, many university professors and advisors assume that their students know how to structure a PhD. Books have literally been written on the subject, but there’s no need to read a book in order to know about PhD thesis paper format and structure. With that said, however, it’s important to understand that your PhD thesis format requirement may not be the same as another student’s. The bottom line is that how to structure a PhD thesis often depends on your university and department guidelines.

But, let’s take a look at a general PhD thesis format. We’ll look at the main sections, and how to connect them to each other. We’ll also examine different hints and tips for each of the sections. As you read through this toolkit, compare it to published PhD theses in your area of study to see how a real-life example looks.

Main Sections of a PhD Thesis

In almost every PhD thesis or dissertation, there are standard sections. Of course, some of these may differ, depending on your university or department requirements, as well as your topic of study, but this will give you a good idea of the basic components of a PhD thesis format.

• Abstract : The abstract is a brief summary that quickly outlines your research, touches on each of the main sections of your thesis, and clearly outlines your contribution to the field by way of your PhD thesis. Even though the abstract is very short, similar to what you’ve seen in published research articles, its impact shouldn’t be underestimated. The abstract is there to answer the most important question to the reviewer. “Why is this important?”
• Introduction : In this section, you help the reviewer understand your entire dissertation, including what your paper is about, why it’s important to the field, a brief description of your methodology, and how your research and the thesis are laid out. Think of your introduction as an expansion of your abstract.
• Literature Review : Within the literature review, you are making a case for your new research by telling the story of the work that’s already been done. You’ll cover a bit about the history of the topic at hand, and how your study fits into the present and future.
• Theory Framework : Here, you explain assumptions related to your study. Here you’re explaining to the review what theoretical concepts you might have used in your research, how it relates to existing knowledge and ideas.
• Methods : This section of a PhD thesis is typically the most detailed and descriptive, depending of course on your research design. Here you’ll discuss the specific techniques you used to get the information you were looking for, in addition to how those methods are relevant and appropriate, as well as how you specifically used each method described.
• Results : Here you present your empirical findings. This section is sometimes also called the “empiracles” chapter. This section is usually pretty straightforward and technical, and full of details. Don’t shortcut this chapter.
• Discussion : This can be a tricky chapter, because it’s where you want to show the reviewer that you know what you’re talking about. You need to speak as a PhD versus a student. The discussion chapter is similar to the empirical/results chapter, but you’re building on those results to push the new information that you learned, prior to making your conclusion.
• Conclusion : Here, you take a step back and reflect on what your original goals and intentions for the research were. You’ll outline them in context of your new findings and expertise.

Tips for your PhD Thesis Format

As you put together your PhD thesis, it’s easy to get a little overwhelmed. Here are some tips that might keep you on track.

• Don’t try to write your PhD as a first-draft. Every great masterwork has typically been edited, and edited, and…edited.
• Work with your thesis supervisor to plan the structure and format of your PhD thesis. Be prepared to rewrite each section, as you work out rough drafts. Don’t get discouraged by this process. It’s typical.
• Make your writing interesting. Academic writing has a reputation of being very dry.
• You don’t have to necessarily work on the chapters and sections outlined above in chronological order. Work on each section as things come up, and while your work on that section is relevant to what you’re doing.
• Don’t rush things. Write a first draft, and leave it for a few days, so you can come back to it with a more critical take. Look at it objectively and carefully grammatical errors, clarity, logic and flow.
• Know what style your references need to be in, and utilize tools out there to organize them in the required format.
• It’s easier to accidentally plagiarize than you think. Make sure you’re referencing appropriately, and check your document for inadvertent plagiarism throughout your writing process.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

• A Guide to Writing a PhD Thesis

Written by Ben Taylor

A PhD thesis is a work of original research all students are requiured to submit in order to succesfully complete their PhD. The thesis details the research that you carried out during the course of your doctoral degree and highlights the outcomes and conclusions reached.

The PhD thesis is the most important part of a doctoral research degree: the culmination of three or four years of full-time work towards producing an original contribution to your academic field.

Your PhD dissertation can therefore seem like quite a daunting possibility, with a hefty word count, the pressure of writing something new and, of course, the prospect of defending it at a viva once you’ve finished.

This page will give you an introduction to what you need to know about the doctoral thesis, with advice on structure, feedback, submission and more.

Beginning your phd thesis.

The first stage of your PhD thesis will usually be the literature review . We’ve already written a detailed guide to what the PhD literature review involves , but here’s what you need to know about this stage of your PhD:

• The literature review is a chance for you to display your knowledge and understanding of what’s already been written about your research area – this could consist of papers, articles, books, data and more
• Rather than simply summarising what other scholars have said about your subject, you should aim to assess and analyse their arguments
• The literature review is usually the first task of your PhD – and typically forms the first part or chapter of your dissertation

After finishing your literature review, you’ll move onto the bulk of your doctoral thesis. Of course, you’ll eventually return to the lit review to make sure it’s up-to-date and contains any additional material you may have come across during the course of your research.

PhD thesis research

What sets your PhD thesis apart from previous university work you’ve done is the fact that it should represent an original contribution to academic knowledge . The form that this original contribution takes will largely depend on your discipline.

• Arts and Humanities dissertations usually involve investigating different texts, sources and theoretical frameworks
• Social Sciences are more likely to focus on qualitive or quantitative surveys and case studies
• STEM subjects involve designing, recording and analysing experiments, using their data to prove or disprove a set theory

Depending on the nature of your research, you may ‘write up’ your findings as you go, or leave it until the dedicated ‘writing-up’ period, usually in the third year of your PhD. Whatever your approach, it’s vital to keep detailed notes of your sources and methods – it’ll make your life a lot easier when it comes to using references in your dissertation further down the line.

PhD thesis vs dissertation

It’s common to use the terms ‘thesis’ and ‘dissertation’ interchangeably, but strictly speaking there is a difference in meaning between them:

• Your thesis is your argument. It’s the conclusions you’ve arrived at through surveying existing scholarship in your literature review and combining this with the results of your own original research.
• Your dissertation is the written statement of your thesis. This is where you lay out your findings in a way that systematically demonstrates and proves your conclusion.

Put simply, you submit a dissertation, but it’s the thesis it attempts to prove that will form the basis of your PhD.

What this also means is that the writing up of your dissertation generally follows the formulation of your doctoral thesis (it’s fairly difficult to write up a PhD before you know what you want to say!).

However, it’s normal for universities and academics to use either (or both) terms when describing PhD research – indeed, we use both ‘thesis’ and ‘dissertation’ across our website.

If you’re studying an MPhil, it’s normal to ‘ upgrade ’ it into a PhD. Find mroe information on our guide.

PhD thesis structure

Having completed your initial literature review and conducted your original research, you’ll move onto the next phase of your doctoral dissertation, beginning to sketch out a plan that your thesis will follow.

The exact structure and make-up of your doctoral thesis will vary between fields, but this is the general template that many dissertations follow:

• Introduction – This sets out the key objectives of your project, why the work is significant and what its original contribution to knowledge is. At this point you may also summarise the remaining chapters, offering an abstract of the argument you will go on to develop.
• Literature review – The introduction will generally lead into a write-up of your literature review. Here you’ll outline the scholarly context for your project. You’ll acknowledge where existing research has shaped your PhD, but emphasise the unique nature of your work.
• Chapters – After you’ve finished introducing your research, you’ll begin the bulk of the dissertation. This will summarise your results and begin explaining the argument you have based on them. Some PhDs will also include specific chapters on methodology and / or a recreation of the data you have developed. Others will develop your argument over a series of stages, drawing on sources and results as relevant.
• Conclusion – The dissertation will end with a final chapter that pulls together the different elements of your argument and the evidence you have provided for it. You’ll restate the significance of your project (and its all-important original contribution to knowledge). You may also take the opportunity to acknowledge the potential for further work or opportunities to apply your findings outside academia.
• Bibliography and appendices – At the end of your thesis, you’ll need to include a full list of the books, articles and data you’ve referenced in a bibliography. You may also need to provide additional information in the form of an appendix.

How long is a PhD thesis?

The length of a PhD thesis varies from subject to subject, but all are far longer than those for undergraduate or Masters degrees. Your university will usually set an upper limit – typically between 70,000 and 100,000 words, with most dissertations coming in at around 80,000 words.

Generally speaking, STEM-based theses will be a little shorter than those in the Arts, Humanities and Social Sciences.

Different universities (and departments) will have different policies regarding what counts towards the PhD thesis word count, so make sure you’re aware what is expected of you. Check with your supervisor whether references, the bibliography or appendices are included in the word count for your dissertation.

How many chapters should a PhD thesis have?

There’s no hard and fast rule for the numbers of chapters in a PhD thesis, but most will have four or five chapters (in addition to the introduction and conclusion). This is the sort of thing you’ll discuss with your supervisor when planning out your research.

Writing up your PhD thesis

Once you’ve conducted your research and settled upon your thesis, there’s only one thing left to do: get it down on paper. Appropriately enough, this final part of a PhD is often referred to as the ‘ writing up period ’.

This is when you produce the final dissertation, which will be submitted as the basis for your viva voce exam. The nature of this task can vary from PhD to PhD.

In some cases you may already have a large amount of chapter drafts and other material. ‘Writing up’ therefore becomes a process of re-drafting and assembling this work into a final dissertation. This approach is common in Arts and Humanities subjects where PhD students tend to work through stages of a project, writing as they go.

Alternatively, you may have spent most of your PhD collecting and analysing data. If so, you’ll now ‘write up’ your findings and conclusions in order to produce your final dissertation. This approach is more common in STEM subjects, where experiment design and data collection are much more resource intensive.

Whatever process you adopt, you’ll now produce a persuasive and coherent statement of your argument, ready to submit for examination.

PhD thesis feedback

Your supervisor will usually give you feedback on each chapter draft, and then feedback on the overall completed dissertation draft before you submit it for examination. When the thesis is a work-in-progress, their comments will be a chance for them to make sure your research is going in the right direction and for you to ask their advice on anything you’re concerned about. This feedback will normally be given in the form of a supervisory meeting.

Although your PhD supervisor will be happy to give you advice on your work, you shouldn’t expect them to be an editor – it’s not their responsibility to correct grammatical or spelling mistakes, and you should make sure any drafts you submit to them are as error-free as possible. Similarly, they won’t be willing to edit your work down to fit a particular word count.

Finishing your PhD thesis

When you’ve finished the final draft of your doctoral thesis and it’s been approved by your supervisor, you’ll submit it for examination. This is when it’s sent to the examiners who will conduct your viva.

Submitting your thesis involves printing enough copies for your examiners and the university’s repository. Don’t leave this until the last minute – printing multiple copies of a 300-page document is a substantial undertaking and you should always allow enough time to account for any possible glitches or issues with the printing process.

Your viva will usually take place within three months of submitting your thesis. You can find out more in our dedicated guide to the PhD viva . After your viva, your examiners will give you a report that confirms whether or not you need to make any changes to your thesis, with several different potential outcomes:

• Pass – You’ve received your doctoral qualification!
• Minor corrections – These are usually fairly small edits, tweaks and improvements to your thesis, which you’ll be given three months to implement
• Major corrections – For these substantial changes, you may have to rewrite part of your dissertation or complete extra research, with a six-month deadline

Most PhD students will need to fix some corrections with their thesis (hopefully not major ones). It’s very rare for a dissertation to be failed.

Once you’ve made any necessary changes to your thesis, you’ll submit it one last time (usually electronically).

If you have plans to publish all or part of your work, you may want to request an embargo so that it won’t be visible to the public for a certain time. 12 months is a fairly standard time period for this, although you may want to ask for a longer embargo if you know that you want to turn your thesis into a book or monograph.

PhD thesis types: Monograph and collection of articles

Starting PhD students often face a difficult choice. They have to decide whether they want to write their dissertation in the form of a monograph, or as a collection of journal articles. Some universities have strict requirements, not leaving a choice. But most offer both options. The decision is left to students and their supervisors and requires careful consideration.

Writing a thesis as a monograph

A monograph resembles an academic book. It typically has an introductory chapter, a methodology chapter, and a literature review chapter. Then, the empirical results of the PhD study are presented in several chapters of analysis. The final discussion and conclusion chapter wraps up the study.

In some countries, monographs are still the norm. In others, theses based on academic articles are becoming increasingly popular.

Dissertation Structure & Layout 101: How to structure your dissertation, thesis or research project.

By: Derek Jansen (MBA) Reviewed By: David Phair (PhD) | July 2019

So, you’ve got a decent understanding of what a dissertation is , you’ve chosen your topic and hopefully you’ve received approval for your research proposal . Awesome! Now its time to start the actual dissertation or thesis writing journey.

To craft a high-quality document, the very first thing you need to understand is dissertation structure . In this post, we’ll walk you through the generic dissertation structure and layout, step by step. We’ll start with the big picture, and then zoom into each chapter to briefly discuss the core contents. If you’re just starting out on your research journey, you should start with this post, which covers the big-picture process of how to write a dissertation or thesis .

*The Caveat *

In this post, we’ll be discussing a traditional dissertation/thesis structure and layout, which is generally used for social science research across universities, whether in the US, UK, Europe or Australia. However, some universities may have small variations on this structure (extra chapters, merged chapters, slightly different ordering, etc).

So, always check with your university if they have a prescribed structure or layout that they expect you to work with. If not, it’s safe to assume the structure we’ll discuss here is suitable. And even if they do have a prescribed structure, you’ll still get value from this post as we’ll explain the core contents of each section.  

Overview: S tructuring a dissertation or thesis

• Acknowledgements page
• Abstract (or executive summary)
• Table of contents , list of figures and tables
• Chapter 1: Introduction
• Chapter 2: Literature review
• Chapter 3: Methodology
• Chapter 4: Results
• Chapter 5: Discussion
• Chapter 6: Conclusion
• Reference list

As I mentioned, some universities will have slight variations on this structure. For example, they want an additional “personal reflection chapter”, or they might prefer the results and discussion chapter to be merged into one. Regardless, the overarching flow will always be the same, as this flow reflects the research process , which we discussed here – i.e.:

• The introduction chapter presents the core research question and aims .
• The literature review chapter assesses what the current research says about this question.
• The methodology, results and discussion chapters go about undertaking new research about this question.
• The conclusion chapter (attempts to) answer the core research question .

In other words, the dissertation structure and layout reflect the research process of asking a well-defined question(s), investigating, and then answering the question – see below.

To restate that – the structure and layout of a dissertation reflect the flow of the overall research process . This is essential to understand, as each chapter will make a lot more sense if you “get” this concept. If you’re not familiar with the research process, read this post before going further.

Right. Now that we’ve covered the big picture, let’s dive a little deeper into the details of each section and chapter. Oh and by the way, you can also grab our free dissertation/thesis template here to help speed things up.

The title page of your dissertation is the very first impression the marker will get of your work, so it pays to invest some time thinking about your title. But what makes for a good title? A strong title needs to be 3 things:

• Succinct (not overly lengthy or verbose)
• Specific (not vague or ambiguous)
• Representative of the research you’re undertaking (clearly linked to your research questions)

Typically, a good title includes mention of the following:

• The broader area of the research (i.e. the overarching topic)
• The specific focus of your research (i.e. your specific context)
• Indication of research design (e.g. quantitative , qualitative , or  mixed methods ).

For example:

A quantitative investigation [research design] into the antecedents of organisational trust [broader area] in the UK retail forex trading market [specific context/area of focus].

Again, some universities may have specific requirements regarding the format and structure of the title, so it’s worth double-checking expectations with your institution (if there’s no mention in the brief or study material).

Acknowledgements

This page provides you with an opportunity to say thank you to those who helped you along your research journey. Generally, it’s optional (and won’t count towards your marks), but it is academic best practice to include this.

So, who do you say thanks to? Well, there’s no prescribed requirements, but it’s common to mention the following people:

• Your dissertation supervisor or committee.
• Any professors, lecturers or academics that helped you understand the topic or methodologies.
• Any tutors, mentors or advisors.
• Your family and friends, especially spouse (for adult learners studying part-time).

There’s no need for lengthy rambling. Just state who you’re thankful to and for what (e.g. thank you to my supervisor, John Doe, for his endless patience and attentiveness) – be sincere. In terms of length, you should keep this to a page or less.

Abstract or executive summary

The dissertation abstract (or executive summary for some degrees) serves to provide the first-time reader (and marker or moderator) with a big-picture view of your research project. It should give them an understanding of the key insights and findings from the research, without them needing to read the rest of the report – in other words, it should be able to stand alone .

For it to stand alone, your abstract should cover the following key points (at a minimum):

• Your research questions and aims – what key question(s) did your research aim to answer?
• Your methodology – how did you go about investigating the topic and finding answers to your research question(s)?
• Your findings – following your own research, what did do you discover?
• Your conclusions – based on your findings, what conclusions did you draw? What answers did you find to your research question(s)?

So, in much the same way the dissertation structure mimics the research process, your abstract or executive summary should reflect the research process, from the initial stage of asking the original question to the final stage of answering that question.

In practical terms, it’s a good idea to write this section up last , once all your core chapters are complete. Otherwise, you’ll end up writing and rewriting this section multiple times (just wasting time). For a step by step guide on how to write a strong executive summary, check out this post .

Table of contents

This section is straightforward. You’ll typically present your table of contents (TOC) first, followed by the two lists – figures and tables. I recommend that you use Microsoft Word’s automatic table of contents generator to generate your TOC. If you’re not familiar with this functionality, the video below explains it simply:

If you find that your table of contents is overly lengthy, consider removing one level of depth. Oftentimes, this can be done without detracting from the usefulness of the TOC.

Right, now that the “admin” sections are out of the way, its time to move on to your core chapters. These chapters are the heart of your dissertation and are where you’ll earn the marks. The first chapter is the introduction chapter – as you would expect, this is the time to introduce your research…

It’s important to understand that even though you’ve provided an overview of your research in your abstract, your introduction needs to be written as if the reader has not read that (remember, the abstract is essentially a standalone document). So, your introduction chapter needs to start from the very beginning, and should address the following questions:

• What will you be investigating (in plain-language, big picture-level)?
• Why is that worth investigating? How is it important to academia or business? How is it sufficiently original?
• What are your research aims and research question(s)? Note that the research questions can sometimes be presented at the end of the literature review (next chapter).
• What is the scope of your study? In other words, what will and won’t you cover ?
• How will you approach your research? In other words, what methodology will you adopt?
• How will you structure your dissertation? What are the core chapters and what will you do in each of them?

These are just the bare basic requirements for your intro chapter. Some universities will want additional bells and whistles in the intro chapter, so be sure to carefully read your brief or consult your research supervisor.

If done right, your introduction chapter will set a clear direction for the rest of your dissertation. Specifically, it will make it clear to the reader (and marker) exactly what you’ll be investigating, why that’s important, and how you’ll be going about the investigation. Conversely, if your introduction chapter leaves a first-time reader wondering what exactly you’ll be researching, you’ve still got some work to do.

Now that you’ve set a clear direction with your introduction chapter, the next step is the literature review . In this section, you will analyse the existing research (typically academic journal articles and high-quality industry publications), with a view to understanding the following questions:

• What does the literature currently say about the topic you’re investigating?
• Is the literature lacking or well established? Is it divided or in disagreement?
• How does your research fit into the bigger picture?
• How does your research contribute something original?
• How does the methodology of previous studies help you develop your own?

Depending on the nature of your study, you may also present a conceptual framework towards the end of your literature review, which you will then test in your actual research.

Again, some universities will want you to focus on some of these areas more than others, some will have additional or fewer requirements, and so on. Therefore, as always, its important to review your brief and/or discuss with your supervisor, so that you know exactly what’s expected of your literature review chapter.

Now that you’ve investigated the current state of knowledge in your literature review chapter and are familiar with the existing key theories, models and frameworks, its time to design your own research. Enter the methodology chapter – the most “science-ey” of the chapters…

In this chapter, you need to address two critical questions:

• Exactly HOW will you carry out your research (i.e. what is your intended research design)?
• Exactly WHY have you chosen to do things this way (i.e. how do you justify your design)?

Remember, the dissertation part of your degree is first and foremost about developing and demonstrating research skills . Therefore, the markers want to see that you know which methods to use, can clearly articulate why you’ve chosen then, and know how to deploy them effectively.

Importantly, this chapter requires detail – don’t hold back on the specifics. State exactly what you’ll be doing, with who, when, for how long, etc. Moreover, for every design choice you make, make sure you justify it.

In practice, you will likely end up coming back to this chapter once you’ve undertaken all your data collection and analysis, and revise it based on changes you made during the analysis phase. This is perfectly fine. Its natural for you to add an additional analysis technique, scrap an old one, etc based on where your data lead you. Of course, I’m talking about small changes here – not a fundamental switch from qualitative to quantitative, which will likely send your supervisor in a spin!

You’ve now collected your data and undertaken your analysis, whether qualitative, quantitative or mixed methods. In this chapter, you’ll present the raw results of your analysis . For example, in the case of a quant study, you’ll present the demographic data, descriptive statistics, inferential statistics , etc.

Typically, Chapter 4 is simply a presentation and description of the data, not a discussion of the meaning of the data. In other words, it’s descriptive, rather than analytical – the meaning is discussed in Chapter 5. However, some universities will want you to combine chapters 4 and 5, so that you both present and interpret the meaning of the data at the same time. Check with your institution what their preference is.

Now that you’ve presented the data analysis results, its time to interpret and analyse them. In other words, its time to discuss what they mean, especially in relation to your research question(s).

What you discuss here will depend largely on your chosen methodology. For example, if you’ve gone the quantitative route, you might discuss the relationships between variables . If you’ve gone the qualitative route, you might discuss key themes and the meanings thereof. It all depends on what your research design choices were.

Most importantly, you need to discuss your results in relation to your research questions and aims, as well as the existing literature. What do the results tell you about your research questions? Are they aligned with the existing research or at odds? If so, why might this be? Dig deep into your findings and explain what the findings suggest, in plain English.

The final chapter – you’ve made it! Now that you’ve discussed your interpretation of the results, its time to bring it back to the beginning with the conclusion chapter . In other words, its time to (attempt to) answer your original research question s (from way back in chapter 1). Clearly state what your conclusions are in terms of your research questions. This might feel a bit repetitive, as you would have touched on this in the previous chapter, but its important to bring the discussion full circle and explicitly state your answer(s) to the research question(s).

Next, you’ll typically discuss the implications of your findings . In other words, you’ve answered your research questions – but what does this mean for the real world (or even for academia)? What should now be done differently, given the new insight you’ve generated?

Lastly, you should discuss the limitations of your research, as well as what this means for future research in the area. No study is perfect, especially not a Masters-level. Discuss the shortcomings of your research. Perhaps your methodology was limited, perhaps your sample size was small or not representative, etc, etc. Don’t be afraid to critique your work – the markers want to see that you can identify the limitations of your work. This is a strength, not a weakness. Be brutal!

This marks the end of your core chapters – woohoo! From here on out, it’s pretty smooth sailing.

The reference list is straightforward. It should contain a list of all resources cited in your dissertation, in the required format, e.g. APA , Harvard, etc.

It’s essential that you use reference management software for your dissertation. Do NOT try handle your referencing manually – its far too error prone. On a reference list of multiple pages, you’re going to make mistake. To this end, I suggest considering either Mendeley or Zotero. Both are free and provide a very straightforward interface to ensure that your referencing is 100% on point. I’ve included a simple how-to video for the Mendeley software (my personal favourite) below:

Some universities may ask you to include a bibliography, as opposed to a reference list. These two things are not the same . A bibliography is similar to a reference list, except that it also includes resources which informed your thinking but were not directly cited in your dissertation. So, double-check your brief and make sure you use the right one.

The very last piece of the puzzle is the appendix or set of appendices. This is where you’ll include any supporting data and evidence. Importantly, supporting is the keyword here.

Your appendices should provide additional “nice to know”, depth-adding information, which is not critical to the core analysis. Appendices should not be used as a way to cut down word count (see this post which covers how to reduce word count ). In other words, don’t place content that is critical to the core analysis here, just to save word count. You will not earn marks on any content in the appendices, so don’t try to play the system!

Time to recap…

And there you have it – the traditional dissertation structure and layout, from A-Z. To recap, the core structure for a dissertation or thesis is (typically) as follows:

• Acknowledgments page

Most importantly, the core chapters should reflect the research process (asking, investigating and answering your research question). Moreover, the research question(s) should form the golden thread throughout your dissertation structure. Everything should revolve around the research questions, and as you’ve seen, they should form both the start point (i.e. introduction chapter) and the endpoint (i.e. conclusion chapter).

What Is a Dissertation? | 5 Essential Questions to Get Started

Published on 26 March 2020 by Jack Caulfield . Revised on 5 May 2022.

A dissertation is a large research project undertaken at the end of a degree. It involves in-depth consideration of a problem or question chosen by the student. It is usually the largest (and final) piece of written work produced during a degree.

The length and structure of a dissertation vary widely depending on the level and field of study. However, there are some key questions that can help you understand the requirements and get started on your dissertation project.

Table of contents

When and why do you have to write a dissertation, who will supervise your dissertation, what type of research will you do, how should your dissertation be structured, what formatting and referencing rules do you have to follow, frequently asked questions about dissertations.

A dissertation, sometimes called a thesis, comes at the end of an undergraduate or postgraduate degree. It is a larger project than the other essays you’ve written, requiring a higher word count and a greater depth of research.

You’ll generally work on your dissertation during the final year of your degree, over a longer period than you would take for a standard essay . For example, the dissertation might be your main focus for the last six months of your degree.

Why is the dissertation important?

The dissertation is a test of your capacity for independent research. You are given a lot of autonomy in writing your dissertation: you come up with your own ideas, conduct your own research, and write and structure the text by yourself.

This means that it is an important preparation for your future, whether you continue in academia or not: it teaches you to manage your own time, generate original ideas, and work independently.

Prevent plagiarism, run a free check.

During the planning and writing of your dissertation, you’ll work with a supervisor from your department. The supervisor’s job is to give you feedback and advice throughout the process.

The dissertation supervisor is often assigned by the department, but you might be allowed to indicate preferences or approach potential supervisors. If so, try to pick someone who is familiar with your chosen topic, whom you get along with on a personal level, and whose feedback you’ve found useful in the past.

How will your supervisor help you?

Your supervisor is there to guide you through the dissertation project, but you’re still working independently. They can give feedback on your ideas, but not come up with ideas for you.

You may need to take the initiative to request an initial meeting with your supervisor. Then you can plan out your future meetings and set reasonable deadlines for things like completion of data collection, a structure outline, a first chapter, a first draft, and so on.

Make sure to prepare in advance for your meetings. Formulate your ideas as fully as you can, and determine where exactly you’re having difficulties so you can ask your supervisor for specific advice.

Your approach to your dissertation will vary depending on your field of study. The first thing to consider is whether you will do empirical research , which involves collecting original data, or non-empirical research , which involves analysing sources.

Empirical dissertations (sciences)

An empirical dissertation focuses on collecting and analysing original data. You’ll usually write this type of dissertation if you are studying a subject in the sciences or social sciences.

• What are airline workers’ attitudes towards the challenges posed for their industry by climate change?
• How effective is cognitive behavioural therapy in treating depression in young adults?
• What are the short-term health effects of switching from smoking cigarettes to e-cigarettes?

There are many different empirical research methods you can use to answer these questions – for example, experiments , observations, surveys , and interviews.

When doing empirical research, you need to consider things like the variables you will investigate, the reliability and validity of your measurements, and your sampling method . The aim is to produce robust, reproducible scientific knowledge.

Non-empirical dissertations (arts and humanities)

A non-empirical dissertation works with existing research or other texts, presenting original analysis, critique and argumentation, but no original data. This approach is typical of arts and humanities subjects.

• What attitudes did commentators in the British press take towards the French Revolution in 1789–1792?
• How do the themes of gender and inheritance intersect in Shakespeare’s Macbeth ?
• How did Plato’s Republic and Thomas More’s Utopia influence nineteenth century utopian socialist thought?

The first steps in this type of dissertation are to decide on your topic and begin collecting your primary and secondary sources .

Primary sources are the direct objects of your research. They give you first-hand evidence about your subject. Examples of primary sources include novels, artworks and historical documents.

Secondary sources provide information that informs your analysis. They describe, interpret, or evaluate information from primary sources. For example, you might consider previous analyses of the novel or author you are working on, or theoretical texts that you plan to apply to your primary sources.

Dissertations are divided into chapters and sections. Empirical dissertations usually follow a standard structure, while non-empirical dissertations are more flexible.

Structure of an empirical dissertation

Empirical dissertations generally include these chapters:

• Introduction : An explanation of your topic and the research question(s) you want to answer.
• Literature review : A survey and evaluation of previous research on your topic.
• Methodology : An explanation of how you collected and analysed your data.
• Results : A brief description of what you found.
• Discussion : Interpretation of what these results reveal.
• Conclusion : Answers to your research question(s) and summary of what your findings contribute to knowledge in your field.

Sometimes the order or naming of chapters might be slightly different, but all of the above information must be included in order to produce thorough, valid scientific research.

Other dissertation structures

If your dissertation doesn’t involve data collection, your structure is more flexible. You can think of it like an extended essay – the text should be logically organised in a way that serves your argument:

• Introduction: An explanation of your topic and the question(s) you want to answer.
• Main body: The development of your analysis, usually divided into 2–4 chapters.
• Conclusion: Answers to your research question(s) and summary of what your analysis contributes to knowledge in your field.

The chapters of the main body can be organised around different themes, time periods, or texts. Below you can see some example structures for dissertations in different subjects.

• Political philosophy

This example, on the topic of the British press’s coverage of the French Revolution, shows how you might structure each chapter around a specific theme.

This example, on the topic of Plato’s and More’s influences on utopian socialist thought, shows a different approach to dividing the chapters by theme.

This example, a master’s dissertation on the topic of how writers respond to persecution, shows how you can also use section headings within each chapter. Each of the three chapters deals with a specific text, while the sections are organised thematically.

Like other academic texts, it’s important that your dissertation follows the formatting guidelines set out by your university. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

Formatting guidelines concern things like:

• line spacing
• page numbers
• punctuation
• title pages
• presentation of tables and figures

If you’re unsure about the formatting requirements, check with your supervisor or department. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

How will you reference your sources?

Referencing means properly listing the sources you cite and refer to in your dissertation, so that the reader can find them. This avoids plagiarism by acknowledging where you’ve used the work of others.

Keep track of everything you read as you prepare your dissertation. The key information to note down for a reference is:

• The publication date
• Page numbers for the parts you refer to (especially when using direct quotes)

Different referencing styles each have their own specific rules for how to reference. The most commonly used styles in UK universities are listed below.

You can use the free APA Reference Generator to automatically create and store your references.

APA Reference Generator

The words ‘ dissertation ’ and ‘thesis’ both refer to a large written research project undertaken to complete a degree, but they are used differently depending on the country:

• In the UK, you write a dissertation at the end of a bachelor’s or master’s degree, and you write a thesis to complete a PhD.
• In the US, it’s the other way around: you may write a thesis at the end of a bachelor’s or master’s degree, and you write a dissertation to complete a PhD.

The main difference is in terms of scale – a dissertation is usually much longer than the other essays you complete during your degree.

Another key difference is that you are given much more independence when working on a dissertation. You choose your own dissertation topic , and you have to conduct the research and write the dissertation yourself (with some assistance from your supervisor).

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

At the bachelor’s and master’s levels, the dissertation is usually the main focus of your final year. You might work on it (alongside other classes) for the entirety of the final year, or for the last six months. This includes formulating an idea, doing the research, and writing up.

A PhD thesis takes a longer time, as the thesis is the main focus of the degree. A PhD thesis might be being formulated and worked on for the whole four years of the degree program. The writing process alone can take around 18 months.

How to write a Doctoral Thesis

Prof. HR Ahmad, Department of Biological and Biomedical Sciences, The Aga Khan University, Karachi, Pakistan. E-mail: [email protected]

Note: * Ahmad HR. In: Medical Writing. Eds. SA Jawaid, MH Jafary & SJ Zuberi. PMJA, 1997 Ed II: 133-142.

PATIENT care and teaching are rather well established components of our medical career. However, with the passage of time a third component has started to influence our medical culture, namely research. 1 - 4 How to accept this challenge is a question. 5 Indeed, teaching and research form a dialectic unit, meaning that teaching without a research component is like a soup without salt. It is a well-established fact that the research activity of an institution is directly proportional to the number of qualified and committed PhD candidates. An inspiring infrastructure, laboratory facilities and libraries are pre-requisites for a research culture to grow. 6 - 8 This forms the basis of a generation cycle for an institution, so that research activity and its culture continues to grow from one generation to the next. The main objective of doctoral work in biomedical sciences is to develop a galaxy of scientist physicians and surgeons possessing high degree of humility, selflessness and ethical superiority. Such a programme will add a scholastic dimension to the clinical faculty.

Education in how to write a doctoral thesis or dissertation should be a part of the postgraduate curriculum, parallel to the laboratory work and Journal Club activities during the PhD studies and/or residency levels. 9 , 10 The overall structure of a doctoral thesis is internationally standardized. However, it varies in style and quality, depending upon how original the work is, and how much the author has understood the work. Therefore a thorough discussion with supervisor, colleagues and assistance from other authors through correspondence can be useful sources for consultation.

The choice of a topic for a doctoral thesis is a crucial step. It should be determined by scanning the literature whether the topic is original or similar work has already been done even a hundred years ago. It is the responsibility of both the supervisor and the PhD candidate to sort out this problem by continuous use of internet and a library. 11 The work leading to the PhD degree can originate from research in following spheres: 12

• b) Methodology
• c) Diagnostic
• d) Therapeutic and Management
• e) Epidemiology

The availability of internationally standardized methods, as well as research committed supervisors can enable physicians and surgeons to do PhD work in both basic and clinical health sciences. The importance of research in basic health sciences cannot be overemphasized. It is rather the base of the applied sciences. There are many instances where the elucidation of a mechanism involved in a process awaits the development of an adequate methodology. 13 In such a scenario; a new method is like a new eye. Research activity in the field of (a) and (b) illuminates the research directions for (c) (d) and (e). It is worth noting that sometimes important basic questions can come from (e) and stimulate research activity in the domain of basic health sciences. 14 , 15

Types of Doctoral Thesis

TYPE-I: Book Form: a classical style. The blueprint of this form is shown in Table-I .

Type-I: The Classical Book Form

TYPE-II: Cumulative Doctoral thesis: A modem but quite useful practice.

INTRODUCTION

A book containing the pearls of a PhD work has standardized divisions and formats, where the number of pages should be weighted in terms of content rather than container. The book includes summary, introduction, materials and methods, results, discussion, conclusions, references and acknowledgements.

Two exercises are mandatory before starting a PhD programme:

• Literature survey using a regular library hours and internet surfing
• Familiarization with the hands-on-experience of methodology involved in the work
• The importance of a continuous literature survey using library, internet and direct correspondence with authors across the globe in the same field cannot be over-emphasized. The main goal of this exercise is to pinpoint the unresolved problem in the literature. An attempt to solve this problem now becomes the topic of the PhD thesis. All the relevant references should be collected, and carefully preserved in the form of a card system arranged alphabetically according to themes and authors. The introduction of the thesis should be styled like a review article with a critical analysis of the work of authors in the literature. The aims of the present PhD work can then also be addressed in the form of questions. The objectives would then deal with how to achieve the aims of the proposed study.

MATERIALS / SUBJECTS AND METHODS

Now comes the most crucial and functional part of the doctoral work, the materials/subjects and methods section. This part can be considered as the motor of the PhD work. The reliability, sensitivity and specificity of the motor must be checked before embarking on a long journey. Controlling the controls is the best guide for a precise and authentic work. Usually materials and methods contain components such as a description of the species involved, their number, age, weight and anthropometric parameters, types of surgical procedures and anesthesia if applied, and a detailed description of methodology. Continuous or point measurements should be thoroughly described. However, a dynamic method should always be preferred to static one.

The experimental protocol should be designed after a small pilot study, which is especially advisable in research on human subjects. A detailed and well-thought experimental protocol forms the basis of conditions under which the results would be obtained. Any deviation from the experimental protocol will affect the outcome, and the interpretation of results. It may be noted that great discoveries are usually accidental and without a protocol, based merely on careful observation! However, for the sake of a publication, a protocol has to be designed after the discovery. After having described the different phases of the experimental protocol with the help of a schematic diagram e.g., showing variables, time period and interventions, the selection of a statistical method should be discussed. Negative results should not be disregarded because they represent the boundary conditions of positive results. Sometimes the negative results are the real results.

It is usual practice that most PhD candidates start writing the methodological components first. This is followed by writing the results. The pre-requisites for writing results are that all figures, tables, schematic diagrams of methods and a working model should be ready. They should be designed in such a way that the information content of each figure should, when projected as a frame be visually clear to audience viewing it from a distance of about fifty feet. It is often observed that the presenters themselves have difficulty in deciphering a frame of the Power-Point being projected in a conference.

The results of a doctoral thesis should be treated like a bride. The flow of writing results becomes easier if all figures and tables are well prepared. This promotes the train of thoughts required to analyze the data in a quantitative fashion. The golden rule of writing results of a thesis is to describe what the figure shows. No explanation is required. One should avoid writing anything which is not there in a figure. Before writing one should observe each diagram for some time and make a list of observations in the form of key words. The more one has understood the information content of a figure; the better will be the fluency of writing. The interruption of the flow in writing most often indicates that an author has not understood the results. Discussion with colleagues or reference to the literature is the only remedy, and it functions sometimes like a caesarean procedure.

Statistical methods are good devices to test the degree of authenticity and precision of results if appropriately applied. The application of statistical technique in human studies poses difficulties because of large standard deviations. Outliers must be discussed, if they are excluded for the sake of statistical significance. Large standard deviations can be minimized by increasing the number of observations. If a regression analysis is not weighted, it gives faulty information. The correlation coefficient value can change from 0.7 to 0.4 if the regression analysis is weighted using Fisher’s test. The dissection of effect from artifact should be analysed in such a way that the signal to noise ratio of a parameter should be considered. A competent statistician should always be consulted in order to avoid the danger of distortion of results.

The legend of a figure should be well written. It contains a title, a brief description of variables and interventions, the main effect and a concluding remark conveying the original message. The writing of PhD work is further eased by a well maintained collection of data in the form of log book, original recordings, analyzed references with summaries and compiling the virgin data of the study on master plan sheet to understand the original signals before submitting to the procedures of statistics. The original data belong to the laboratory of an institution where it came into being and should be preserved for 5-7 years in the archive for the sake of brevity.

This is the liveliest part of a thesis. Its main goal is to defend the work by staging a constructive debate with the literature. The golden rule of this written debate should be that a rigid explanation looks backward and a design looks forward. The object is to derive a model out of a jig-saw puzzle of information. It should be designed in such a way that the results of the present study and those of authors from the literature can be better discussed and interpreted. Agreement and disagreement can be better resolved if one considers under what experimental conditions the results were obtained by the various authors. It means that the boundary conditions for each result should be carefully analyzed and compared.

The discussion can be divided into the following parts:

• criticism of material/subjects and methods
• a list of important observations of the present study
• interpretation and comparison of results of other authors using a literature table
• design of a model
• claim of an original research work
• The criticism of the methodological procedure enables a candidate to demonstrate how precisely the research work has been carried out. The interpretation of results depends critically on the strict experimental protocol and methods. For example, an epidemiological work is a study of a population. However, if the population sampling is done regularly at a specific location; the question arises as to how a result derived from a localized place can be applied to the whole population.
• After having discussed at length the strong and weak points of material/subjects and methods, one should list in a telegraphic design the most important observations of the present study. This may form a good agenda to initiate interpretation, argument, reasoning and comparison with results of other authors. The outcome of this constructive debate should permit the design of a working model in the form of a block diagram. All statements should be very carefully referenced. The ratio of agreement and disagreement should indicate the ability of the author to reconcile conflicting data in an objective and quantitative way. Attempts should be made to design a solution out of the given quantum of information. It is also well known that most of the processes of human physiology can only be understood if their time course is known. The dynamic aspect of interpretation of results is therefore more powerful and superior to the static one. 16 Therefore a continuous record of variables should be preferred and sought to reveal the secrets hidden in the kinetics.
• Finally, the discussion should conclude how far the study was successful in answering the questions being posed at the end of the introduction part. Usually a doctoral thesis raises more questions than it answers. In this way research does not come to a standstill and does become a life time engagement for a committed scientist. Also it is important to note that all scientific theses should be quantifiable and falsifiable, otherwise they lose the spirit and fragrance of a scientific research.
• The author’s claim of original work is finally decided by the critical review of his research work by the literature and the number of times being cited. It can be easily read by a high rate of a citation index of a publication and invitation. When a methodological research clicks, one becomes a star overnight.

Type-II: CUMULATIVE DOCTORAL THESES

Another way of writing a doctoral work is a cumulative type of thesis. 11 It consists of a few original publications in refereed journals of repute. It is supplemented by a concise summary about the research work. This type of thesis is usually practiced in Sweden, Germany and other countries. It has the advantage of being doubly refereed by the journals and the faculty of health sciences. Additionally, papers are published during a doctoral work. A declaration has to be given to the faculty of science about the sharing of research work in publications, provided there are co-authors. The weightage should be in favour of the PhD candidate, so that the thesis can ethically be better defended before the team of august research faculty.

What are acceptable dissertation research methods?

August 16, 2023

Reading time:  3–4 minutes

Doctoral research is the cornerstone of a PhD program .

In order to write a dissertation, you must complete extensive, detailed research. Depending on your area of study, different types of research methods will be appropriate to complete your work.

“The choice of research method depends on the questions you hope to answer with your research,” says Curtis Brant, PhD, Capella University dean of research and scholarship.

Once you’ve identified your research problem, you’ll employ the methodology best suited for solving the problem.

There are two primary dissertation research methods: qualitative and quantitative.

Qualitative

Qualitative research focuses on examining the topic via cultural phenomena, human behavior or belief systems. This type of research uses interviews, open-ended questions or focus groups to gain insight into people’s thoughts and beliefs around certain behaviors and systems.

Dr. Brant says there are several approaches to qualitative inquiry. The three most routinely used include:

Generic qualitative inquiry. The researcher focuses on people’s experiences or perceptions in the real world. This often includes, but is not limited to, subjective opinions, attitudes and beliefs .

Case study. The researcher performs an in-depth exploration of a program, event, activity or process with an emphasis on the experience of one or more individuals. The focus of this kind of inquiry must be defined and often includes more than one set of data, such as interviews and field notes, observations or other qualitative data.

Phenomenological. The researcher identifies lived experiences associated with how an individual encounters and engages with the real world .

Qualitative research questions seek to discover:

• A participant’s verbal descriptions of a phenomenon being investigated
•  A researcher’s observations of the phenomenon being investigated
• An integrated interpretation of participant’s descriptions and researchers observations

Quantitative

Quantitative research involves the empirical investigation of observable and measurable variables. It is used for theory testing, predicting outcomes or determining relationships between and among variables using statistical analysis.

According to Dr. Brant, there are two primary data sources for quantitative research.

Surveys: Surveys involve asking people a set of questions, usually testing for linear relationships, statistical differences or statistical independence. This approach is common in correlation research designs.

Archival research (secondary data analysis). Archival research involves using preexisting data to answer research questions instead of collecting data from active human participants.

Quantitative research questions seek to address:

• Descriptions of variables being investigated
• Measurements of relationships between (at least two) variables
• Differences between two or more groups’ scores on a variable or variables

Which method should you choose?

Choosing a qualitative or quantitative methodology for your research will be based on the nature of the questions you ask, the preferred method in your field, the feasibility of the approach and other factors. Many programs offer doctoral mentors and support teams that can help guide you throughout the process.

Capella University offers PhD and professional doctorate degree programs ranging from business to education and health to technology. Learn more about Capella doctoral programs and doctoral support.

Masters Thesis vs. PhD Dissertation: Key Differences

Whether you are a graduate student just starting out in academia or a professor advising a student, making the distinction between a dissertation and a thesis is critically important to writing a strong dissertation and becoming a stronger writer. Unfortunately, the difference remains unclear since the terms are used interchangeably by graduate students, doctoral researchers, academic publishers & universities.

If you’re not sure whether you’re writing a thesis or a dissertation, this article will help you understand the differences between the two whether you’re a PhD or master’s degree student.

Main Differences Between a Dissertation and a Thesis

While theses and dissertations share many similarities (they are both advanced graduate research papers), they actually refer to two different types of academic writing, and their differences include important concepts such as scope, purpose, length, and research requirements.

Most importantly, the difference between a thesis and a dissertation depends on the level of education. Far beyond being a simple essay, a thesis is for graduate students pursuing a master’s degree while a dissertation is written by doctoral students, also referred to as PhD candidates.

There are a few key differences between a thesis versus a dissertation.

The biggest difference between a thesis and a dissertation is that a thesis makes arguments based on existing research. Meanwhile, a dissertation often requires the PhD candidate to conduct research and then perform an analysis.

More specifically, a thesis often takes the form of a literature review , which is a compilation of research knowledge in a particular field of study that proves one is competent in that subject. On the other hand, a dissertation is a more specific type of research paper written by those working toward a specific doctorate degree that contributes knowledge, theory, or methods to a field of study.

What is a master’s thesis?

A master’s thesis is an academic research paper that requires a greater degree of research than an undergraduate thesis or term paper. It is marked by a higher standard of writing, and students are expected to demonstrate competence, literacy, and mastery of a subject. It usually takes two or three years to complete. Finally, a master’s degree thesis is usually written in order to obtain a research degree and is not intended to be published separately.

What is a PhD dissertation?

A PhD dissertation is a substantial piece of independent research that is required of all students who are pursuing a doctorate degree. It is a piece of original work that has not been published elsewhere and, most importantly, makes a new contribution to the field. This contribution may be a new way of thinking about an existing topic or even a novel theory. The research performed for a dissertation is usually conducted over a period of several years to half a decade.

Features of a Master’s Thesis vs PhD Dissertation

Content and Structural Differences

So how is dissertation writing different from thesis writing?

Now that you know the definitions of a dissertation and thesis, let’s dive into some clear ways in which they differ in structure and other main characteristics.

How long is a thesis vs dissertation?

Length is the most obvious factor in differentiating between writing a thesis or dissertation. 

Generally, a doctoral dissertation has greater breadth, depth, and intention than a master’s thesis since it is based on original research. While the standard length of a master’s thesis is around 100 pages , a doctoral dissertation can be upwards of 400-500 pages. 

While most students can finish their PhD dissertation or thesis in as little as 1-2 years, it can take as long as 7 years depending on the school, program, and dissertation topic. As doctoral programs have their own formatting requirements, check with your school or university to find out what you need for your own dissertation or thesis. Most dissertations are organized into chapters, but the number of chapters varies as well.

Differences in research methods

A thesis and dissertation are both graduate-level research reports. This means they require students to investigate and report on a specific topic. But what is the difference in the scale of research between a master’s versus doctoral degree? The answer comes down to how much and what type of data you collect .

Data sources for a thesis vs dissertation

A master’s thesis is limited to secondary or reported knowledge . This knowledge has already been published, analyzed, and scrutinized in the literature. A thesis does not typically offer anything new in that regard. Your purpose is usually to write a comprehensive literature review on a novel or underreported topic using already-reported data.

On the other hand, a doctoral dissertation reports on  novel data  and is published so it can be scrutinized by others. It culminates in your dissertation defense.

The above lists clearly show that a PhD researcher and dissertation writer must have specific hands-on experience about not only the result of others’ research but also how the researchers obtained the data. A dissertation must venture into criticism of how other studies performed their experiments, whereas a master’s student will only report on and evaluate the results.

Differences in research scope 

As mentioned above, a thesis is more of a literature review written to demonstrate competence and mastery of a field of study. In short, you are a reliable “reporter” of information related to that subject. A thesis shows that you know the technical jargon, understand the subject, are familiar with industry tools, and can translate that information to a general audience. This is why a master’s degree is sufficient and often preferred for industry jobs.

In contrast, a doctoral dissertation goes beyond simply using the building blocks of your subject and actually creates new tools, knowledge, and theories to advance the subject as a whole. If a master’s degree holder is like a seasoned Rolling Stone journalist, then a doctorate is the band/musician who actually makes the music.

So should you pursue a thesis or a dissertation?

The benefits of earning a graduate degree are huge. According to the US Census Bureau , those with an advanced degree earn 3.7 times as much as a high school dropout, and 13.1% hold a master’s, professional, or doctorate degree. If you’re a curious undergraduate student thinking of applying to graduate school, which is the right choice?

In short, a dissertation is more focused and in-depth than a thesis. While a doctoral dissertation is based on original research, a thesis is often an extension or review of others’ research in order to demonstrate literacy. Further, a dissertation can be used as the basis or subject of a thesis, but not vice versa.

Editing a Dissertation vs Thesis

So far, we’ve focused a lot on differences such as research and purpose, but in the end, a thesis or dissertation is a written document that requires skill, focus, discipline, subject knowledge, organization, and scheduling. 

For non-native English speakers, the challenge is especially difficult since English is the lingua franca of academia and research. 

How does an editing service improve your dissertation or thesis ?

From body spacing and pagination, to font size and citation formatting, the dissertation guidelines are exhaustive. Even worse, they vary by school. So besides the actual English writing and grammar, graduate students must worry about consistency, formatting, nomenclature, and terminology. That’s quite the burden!

This is why it’s very common for graduate students, especially ESL and foreign ones, to seek out dissertation editing services that specifically cater to the academic needs of researchers and students.

Here are just a few reasons why dissertation proofreading is so helpful and what these editors do:

• Correct grammar, punctuation, syntax, and structural errors
• Offer suggestions to rewrite, remove, and revise writing
• Ensure formatting and nomenclature are consistent
• Knowledgeable academic editors with master’s and PhD degrees
• Free up your time to focus on research, revisions, and content instead of looking for mistakes
• Provide a  language editing certificate , which may be necessary for non-native English-speaking students

Lastly, most PhD advisors recommend that students seek out professional editing services , specifically thesis editing or dissertation editing , since professors prefer to assess the actual research content of a dissertation, not mundane writing errors. Any graduate student reading this knows professors don’t like their time to be wasted!

What Is a Research Methodology? | Steps & Tips

Published on August 25, 2022 by Shona McCombes and Tegan George. Revised on November 20, 2023.

Your research methodology discusses and explains the data collection and analysis methods you used in your research. A key part of your thesis, dissertation , or research paper , the methodology chapter explains what you did and how you did it, allowing readers to evaluate the reliability and validity of your research and your dissertation topic .

It should include:

• The type of research you conducted
• How you collected and analyzed your data
• Any tools or materials you used in the research
• How you mitigated or avoided research biases
• Why you chose these methods
• Your methodology section should generally be written in the past tense .
• Academic style guides in your field may provide detailed guidelines on what to include for different types of studies.
• Your citation style might provide guidelines for your methodology section (e.g., an APA Style methods section ).

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

Your methods section is your opportunity to share how you conducted your research and why you chose the methods you chose. It’s also the place to show that your research was rigorously conducted and can be replicated .

It gives your research legitimacy and situates it within your field, and also gives your readers a place to refer to if they have any questions or critiques in other sections.

You can start by introducing your overall approach to your research. You have two options here.

Option 1: Start with your “what”

What research problem or question did you investigate?

• Aim to describe the characteristics of something?
• Explore an under-researched topic?
• Establish a causal relationship?

And what type of data did you need to achieve this aim?

• Quantitative data , qualitative data , or a mix of both?
• Primary data collected yourself, or secondary data collected by someone else?
• Experimental data gathered by controlling and manipulating variables, or descriptive data gathered via observations?

Option 2: Start with your “why”

Depending on your discipline, you can also start with a discussion of the rationale and assumptions underpinning your methodology. In other words, why did you choose these methods for your study?

• Why is this the best way to answer your research question?
• Is this a standard methodology in your field, or does it require justification?
• Were there any ethical considerations involved in your choices?
• What are the criteria for validity and reliability in this type of research ? How did you prevent bias from affecting your data?

Once you have introduced your reader to your methodological approach, you should share full details about your data collection methods .

Quantitative methods

In order to be considered generalizable, you should describe quantitative research methods in enough detail for another researcher to replicate your study.

Here, explain how you operationalized your concepts and measured your variables. Discuss your sampling method or inclusion and exclusion criteria , as well as any tools, procedures, and materials you used to gather your data.

Surveys Describe where, when, and how the survey was conducted.

• How did you design the questionnaire?
• What form did your questions take (e.g., multiple choice, Likert scale )?
• Were your surveys conducted in-person or virtually?
• What sampling method did you use to select participants?
• What was your sample size and response rate?

Experiments Share full details of the tools, techniques, and procedures you used to conduct your experiment.

• How did you design the experiment ?
• How did you recruit participants?
• How did you manipulate and measure the variables ?
• What tools did you use?

Existing data Explain how you gathered and selected the material (such as datasets or archival data) that you used in your analysis.

• Where did you source the material?
• How was the data originally produced?
• What criteria did you use to select material (e.g., date range)?

The survey consisted of 5 multiple-choice questions and 10 questions measured on a 7-point Likert scale.

The goal was to collect survey responses from 350 customers visiting the fitness apparel company’s brick-and-mortar location in Boston on July 4–8, 2022, between 11:00 and 15:00.

Here, a customer was defined as a person who had purchased a product from the company on the day they took the survey. Participants were given 5 minutes to fill in the survey anonymously. In total, 408 customers responded, but not all surveys were fully completed. Due to this, 371 survey results were included in the analysis.

• Information bias
• Omitted variable bias
• Regression to the mean
• Survivorship bias
• Undercoverage bias
• Sampling bias

Qualitative methods

In qualitative research , methods are often more flexible and subjective. For this reason, it’s crucial to robustly explain the methodology choices you made.

Be sure to discuss the criteria you used to select your data, the context in which your research was conducted, and the role you played in collecting your data (e.g., were you an active participant, or a passive observer?)

Interviews or focus groups Describe where, when, and how the interviews were conducted.

• How did you find and select participants?
• How many participants took part?
• What form did the interviews take ( structured , semi-structured , or unstructured )?
• How long were the interviews?
• How were they recorded?

Participant observation Describe where, when, and how you conducted the observation or ethnography .

• What group or community did you observe? How long did you spend there?
• How did you gain access to this group? What role did you play in the community?
• How long did you spend conducting the research? Where was it located?
• How did you record your data (e.g., audiovisual recordings, note-taking)?

Existing data Explain how you selected case study materials for your analysis.

• What type of materials did you analyze?
• How did you select them?

In order to gain better insight into possibilities for future improvement of the fitness store’s product range, semi-structured interviews were conducted with 8 returning customers.

Here, a returning customer was defined as someone who usually bought products at least twice a week from the store.

Surveys were used to select participants. Interviews were conducted in a small office next to the cash register and lasted approximately 20 minutes each. Answers were recorded by note-taking, and seven interviews were also filmed with consent. One interviewee preferred not to be filmed.

• The Hawthorne effect
• Observer bias
• The placebo effect
• Response bias and Nonresponse bias
• The Pygmalion effect
• Recall bias
• Social desirability bias
• Self-selection bias

Mixed methods

Mixed methods research combines quantitative and qualitative approaches. If a standalone quantitative or qualitative study is insufficient to answer your research question, mixed methods may be a good fit for you.

Mixed methods are less common than standalone analyses, largely because they require a great deal of effort to pull off successfully. If you choose to pursue mixed methods, it’s especially important to robustly justify your methods.

Prevent plagiarism. Run a free check.

Next, you should indicate how you processed and analyzed your data. Avoid going into too much detail: you should not start introducing or discussing any of your results at this stage.

In quantitative research , your analysis will be based on numbers. In your methods section, you can include:

• How you prepared the data before analyzing it (e.g., checking for missing data , removing outliers , transforming variables)
• Which software you used (e.g., SPSS, Stata or R)
• Which statistical tests you used (e.g., two-tailed t test , simple linear regression )

In qualitative research, your analysis will be based on language, images, and observations (often involving some form of textual analysis ).

Specific methods might include:

• Content analysis : Categorizing and discussing the meaning of words, phrases and sentences
• Thematic analysis : Coding and closely examining the data to identify broad themes and patterns
• Discourse analysis : Studying communication and meaning in relation to their social context

Mixed methods combine the above two research methods, integrating both qualitative and quantitative approaches into one coherent analytical process.

Above all, your methodology section should clearly make the case for why you chose the methods you did. This is especially true if you did not take the most standard approach to your topic. In this case, discuss why other methods were not suitable for your objectives, and show how this approach contributes new knowledge or understanding.

In any case, it should be overwhelmingly clear to your reader that you set yourself up for success in terms of your methodology’s design. Show how your methods should lead to results that are valid and reliable, while leaving the analysis of the meaning, importance, and relevance of your results for your discussion section .

• Quantitative: Lab-based experiments cannot always accurately simulate real-life situations and behaviors, but they are effective for testing causal relationships between variables .
• Qualitative: Unstructured interviews usually produce results that cannot be generalized beyond the sample group , but they provide a more in-depth understanding of participants’ perceptions, motivations, and emotions.
• Mixed methods: Despite issues systematically comparing differing types of data, a solely quantitative study would not sufficiently incorporate the lived experience of each participant, while a solely qualitative study would be insufficiently generalizable.

Remember that your aim is not just to describe your methods, but to show how and why you applied them. Again, it’s critical to demonstrate that your research was rigorously conducted and can be replicated.

1. Focus on your objectives and research questions

The methodology section should clearly show why your methods suit your objectives and convince the reader that you chose the best possible approach to answering your problem statement and research questions .

2. Cite relevant sources

Your methodology can be strengthened by referencing existing research in your field. This can help you to:

• Show that you followed established practice for your type of research
• Discuss how you decided on your approach by evaluating existing research
• Present a novel methodological approach to address a gap in the literature

3. Write for your audience

Consider how much information you need to give, and avoid getting too lengthy. If you are using methods that are standard for your discipline, you probably don’t need to give a lot of background or justification.

Regardless, your methodology should be a clear, well-structured text that makes an argument for your approach, not just a list of technical details and procedures.

Methodology refers to the overarching strategy and rationale of your research project . It involves studying the methods used in your field and the theories or principles behind them, in order to develop an approach that matches your objectives.

Methods are the specific tools and procedures you use to collect and analyze data (for example, experiments, surveys , and statistical tests ).

In shorter scientific papers, where the aim is to report the findings of a specific study, you might simply describe what you did in a methods section .

In a longer or more complex research project, such as a thesis or dissertation , you will probably include a methodology section , where you explain your approach to answering the research questions and cite relevant sources to support your choice of methods.

In a scientific paper, the methodology always comes after the introduction and before the results , discussion and conclusion . The same basic structure also applies to a thesis, dissertation , or research proposal .

Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to systematically measure variables and test hypotheses . Qualitative methods allow you to explore concepts and experiences in more detail.

Reliability and validity are both about how well a method measures something:

• Reliability refers to the  consistency of a measure (whether the results can be reproduced under the same conditions).
• Validity   refers to the  accuracy of a measure (whether the results really do represent what they are supposed to measure).

If you are doing experimental research, you also have to consider the internal and external validity of your experiment.

A sample is a subset of individuals from a larger population . Sampling means selecting the group that you will actually collect data from in your research. For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.

In statistics, sampling allows you to test a hypothesis about the characteristics of a population.

Princeton University Library

Phd dissertation and master's thesis submission guidelines.

The Princeton University Archives at the Mudd Manuscript Library is the repository for Ph.D. dissertations and Master’s theses. The Princeton University Archives partners with ProQuest to publish and distribute Princeton University dissertations beyond the campus community.

Below you will find instructions on the submission process and the formatting requirements for your Ph.D. dissertation or Master's thesis. If you have questions about this process, please use our Ask Us form  or visit the Mudd Manuscript Library during our open hours.

Ph.D Dissertation Submission Process

The first step is for the student to prepare their dissertation according to the Dissertation Formatting Requirements . Near the time of the final public oral examination (FPO) (shortly before or immediately after) the student must complete the online submission of their dissertation via the ProQuest UMI ETD Administrator website . Students are required to upload a PDF of their dissertation, choose publishing options, enter subject categories and keywords, and make payment to ProQuest (if fees apply). This step will take roughly 20-25 minutes.

 After the FPO the student should log on to TigerHub  and complete the checkout process. When this step is complete, Mudd Library will be notified for processing. This step will occur M-F during business hours. The Mudd Library staff member will review, apply the embargo (when applicable), and approve the dissertation submission in ProQuest. You will receive an email notification of the approval from ProQuest when it has been approved or needs revisions. 

The vast majority of students will not be required to submit a bound copy of their dissertation to the library. Only students who have removed content from the PDF to avoid copyright infringement are required to submit a bound copy to the library. This unredacted, bound version of the dissertation must be formatted according to the Dissertation Formatting Requirements , and delivered by hand, mail, or delivery service to the Mudd Manuscript Library by the degree date deadline in order to be placed on the degree list. Address the bound copy to: Attn: Dissertations, Mudd Manuscript Library, 65 Olden Street, Princeton, NJ 08540.

ProQuest Publishing Options

When you submit your dissertation to the ProQuest ETD Administrator site, you will be given two options: Traditional Publishing or Open Access Publishing Plus. ProQuest compares the two options in their  Open Access Overview document . Full details will be presented in the ProQuest ETD Administrator site.

Traditional Publishing

No fee  is paid to ProQuest; your dissertation will be available in full text to subscribing institutions only through the ProQuest Dissertations & Theses Global ; If you have an embargo, your dissertation will be unavailable for viewing or purchase through the subscription database during the embargo period.

Open Access Publishing Plus

$95 fee to ProQuest; your dissertation will be available in full text through the Internet to anyone via the ProQuest Database ; if you have an embargo, your dissertation will be unavailable for viewing through the open access database during the embargo period.

Optional Service: Copyright Registration

$75 fee to ProQuest; ProQuest offers the optional service of registering your copyright on your behalf. The dissertation author owns the copyright to their dissertation regardless of copyright registration. Registering your copyright makes a public record of your copyright claim and may entitle you to additional compensation should your copyright be infringed upon. For a full discussion of your dissertation and copyright, see ProQuest’s Copyright and Your Dissertation .

If you have questions regarding the ProQuest publishing options, contact their Author and School Relations team at 1-800-521-0600 ext. 77020 or via email at [email protected] .

Princeton’s Institutional Repository, DataSpace

Each Princeton University dissertation is deposited in Princeton’s Institutional Repository, DataSpace . Dissertations will be freely available on the Internet except during an embargo period. If your dissertation is embargoed, the PDF will be completely restricted during the embargo period. The bound copy, however, will be available for viewing in the Mudd Manuscript Library reading room during the embargo. 

According to the Graduate School’s embargo policy , students can request up to a two-year embargo on their dissertation, with the potential for renewal by petition. If approved, the embargo would apply to the dissertation in ProQuest, as well as in Princeton’s digital repository, DataSpace . Students in the sciences and engineering seeking patents or pursuing journal articles may be approved for a shorter embargo period. Students must apply for the embargo during the Advanced Degree Application process . More information can be found on the Graduate School's Ph.D. Publication, Access and Embargoing webpage .

Those who have been approved for the embargo can choose "Traditional Publishing" or "Open Access Plus" publishing when they complete their online submission to ProQuest. Mudd Manuscript Library staff will apply the embargo in the ProQuest ETD system at the time of submission of materials to the Library. In the case of Open Access Plus, the dissertation would become freely available on the ProQuest open access site when the embargo expires. The embargo in ProQuest will also apply to the embargo in Princeton’s digital repository, DataSpace

Those who wish to request a renewal of an existing embargo must email Assistant Dean Geoffrey Hill and provide the reason for the extension. An embargo renewal must be requested in writing at least one month before the original embargo has expired, but may not be requested more than three months prior to the embargo expiration date. Embargoes cannot be reinstituted after having expired. Embargoes are set to expire two years from the date on which the Ph.D. was awarded (degrees are awarded five times per year at Board of Trustee meetings); this date will coincide with the degree date (month and year) on the title page of your dissertation. Please note: You, the student, are responsible for keeping track of the embargo period--notifications will not be sent.

• To find the exact date of an embargo expiration, individuals can find their dissertation in DataSpace , and view the box at the bottom of the record, which will indicate the embargo expiration date.
• The Graduate School will inform the Mudd Library of all renewals and Mudd Library staff will institute the extensions in ProQuest and DataSpace .   
• Princeton University Archives'  Dissertation Formatting Requirements  (PDF download) document provides detailed information on how to prepare the dissertation PDF and bound volume (if you are required to submit a bound volume). Please take special note of how to format the title page (a title page example is downloadable from the upper-right-hand side of this webpage). The title page must list your adviser’s name.  
• ProQuest's Preparing Your Manuscript guide offers additional information on formatting the PDF. Where there are discrepancies with the Princeton University Archives Dissertation Formatting Requirements document, the Princeton University Archives requirements should be followed. Special consideration should be paid to embedding fonts in the PDF.

• Three types of doctoral dissertation

The Graduate School of Information Systems is involved in the study of and education about the relationship between information systems and the individual/society. Therefore, in addition to investigating and solving the scientific problems of information systems, research here also covers a variety of issues: from building the information systems used widely around the world to analyzing their effect on individuals and society. In order to evaluate properly research conducted from such diverse viewpoints, the school accepts three different types of doctoral dissertation according to the research method, and the degree examination is conducted accordingly. Although the examination is usually conducted by five instructors from the faculty, depending on the content of the research, appropriate external specialists may contribute to provide a more suitable examination.

*Note: regardless of the type of dissertation, the degree granted is either a Doctor of Engineering or Philosophy.

Types of dissertation

1. scientific research dissertation.

This dissertation comprises cutting-edge research of important scientific value and meaning. The examination evaluates its scientific novelty and usefulness. The evaluation criteria are equivalent to those of most typical doctoral dissertations.

Condition for degree acquisition (Doctor's program)

The student must present two original papers, with content relevant to the dissertation, to an academic journal or international conference.

2. System development dissertation

This dissertation contains R＆D on information systems with great social meaning. In the examination, highly useful information systems with a large impact on society are evaluated positively. For example, development leading to:

• Configuration of an information system that serves as a social infrastructure,
• Configuration of a normative, standardized information system applied to many products,
• Highly evaluated software that has been downloaded many times.

In particular, a technology whose results are already in use even if it was developed in the past, or research that supports subsequent technological development, etc., are evaluated highly.

Conditions for degree acquisition (Doctor's program)

The student must show that they led the R&D in published literature (such as papers of an academic society, magazine articles to introduce a company's technology, book or patent, etc.) and also have materials to show that the R&D results are useful to society.

3. Case-study dissertation

This is a research dissertation that analyzes and systematizes a particular example of an information system. In the examination, research that is important to society is highly evaluated, for example, research that can be expected to contribute to future information-system design. This type of dissertation can include research on the effect of the information system on society and its meaning from a new viewpoint, research that considers the position and future course of an information system in its social and historical context, and research related to an information system from the perspective of technology or history of science by investigating and analyzing examples. For example, research that:

• Analyzes the impact on society of a specific information system by sending questionnaires to many users and companies, etc.
• Evaluates the effectiveness of a specific information system in society through the investigation and analysis of it.
• Surveys an example relevant to an information system and discusses it systematically from an original viewpoint.

The contents of the dissertation must be published by an academic society, at a convention, in a bulletin from a university or research institute, specialist magazine, book, etc.

Guidance toward the degree

With the System development and Case-study dissertations in particular, it is important for the student to not only collate past R&D and case-study results, but also systematize the results from a unified viewpoint with a logical through-line. The school's teaching emphasizes the process of systematization so that the final doctoral dissertations are meaningful.

Guide to the Doctor of Education (EdD) Dissertation

The Doctor of Education (EdD) dissertation is considered a central component of EdD programs. The EdD dissertation is a five-chapter document that investigates an issue in education, reviews the existing literature on this issue, adds additional insight through a qualitative and/or quantitative research study, and proposes one or more solutions. It is considered the culmination of a student’s knowledge of education systems and his or her training in the academic research process. Most EdD programs require students to formally publish their dissertation and/or present their findings to a group of faculty and peers.

The dissertation and dissertation defense are two of the most challenging experiences students will have during their program, but are also two of the most engaging and rewarding from an intellectual perspective. The dissertation allows students to truly apply all the skills and knowledge they have gained during their graduate work to an education issue in which they are invested. Below is a more detailed description of EdD dissertations and the important steps students should take to successfully prepare for, complete, and defend their dissertation.

Doctorate of Education Dissertations

EdD dissertations are students’ opportunity to contribute original research on and insight into an issue in education, such as educational disparities, curriculum development or instruction challenges, school funding problems, college counseling and guidance, job skills development, or standardized testing. For their dissertation, students complete research under the guidance of a research mentor, and receive academic credit for this work. Students typically attend seminars and/or other classes that provide structure around the processes of developing a research question, formulating a research plan, reviewing existing academic literature, and writing about their findings. Many programs require students to present their findings to a committee and/or publish their dissertation in an academic journal.

The Structure of EdD Dissertations

As mentioned previously, dissertations are traditionally divided into five chapters: Introduction, Literature Review, Research Methodology, Results and Analysis, and Discussion and Conclusions. A brief description of each chapter section is below:

• Introduction : The introduction includes background information about the topic of study and its purpose, the significance of the student’s research, and existing literature on the subject. It also provides a summary of the results of one’s study, and their implications.
• Literature Review : This section explains the existing literature on the student’s topic of study, and places the student’s work in the context of existing theoretical frameworks that are relevant to one’s research.
• Research Methodology : This chapter focuses on how the student gathers qualitative and/or quantitative data regarding his or her research query.
• Results and Analysis : This section explains in detail the results of the student’s study, and analyzes it to arrive at actionable conclusions.
• Discussion and Conclusions : This chapter places the student’s findings in the context of the educational system(s) of focus (e.g. private or public education, secondary or post-secondary) to illustrate how the student’s research contributes to the larger understanding of the educational issue at hand. This section also makes recommendations for the application of the student’s findings to real-world education practice as well as further research on the subject.

Dissertations are typically very long, in-depth works. Many dissertations are between 100 and 200 pages in length or longer, and seek to comprehensively investigate a specific issue or problem in education. Due to the intensive nature of dissertation research and writing, students must plan their research query and methodology well in advance, and seek the support of research mentors and other faculty throughout the process.

Overview of the EdD Dissertation Completion Process

In general, students begin thinking about their dissertation topic during the second year of their program. The second year is also when students begin taking courses in research and data analysis. The term prior to the beginning of their independent research, students typically take a dissertation seminar, during which they discuss potential research topics to explore and learn more about the academic research process. During their third year, students delve into independent research, while still receiving guidance from their selected faculty research mentor. Students generally submit several drafts to a dissertation committee for review and revision suggestions before they finalize their paper. Upon the completion of their dissertation, students may be required to publish their writing and/or present on their research.

Below is a general timeline of the dissertation completion process, followed by a description of the eight steps to successfully completing an EdD dissertation. The timeline below should be used for example purposes only, as programs vary in terms of when they have students complete their requisite research courses.

The Steps to Completing an EdD Dissertation

Choose a research topic and review the existing literature.

During their classes, students should take note of the topics within education that interest them and the issues that they have encountered during their work in education that they would like to see resolved. These areas are often rich with potential research questions. Conducting research within these areas of interest by reading academic articles is an important step in finding a potential question or issue in education that merits further investigation. It is important that students select a research question that is specific enough to allow for in-depth research, is not overwhelming, and is engaging enough to students to carry them through over a year of independent research.

After identifying their field of focus and preliminary research query, students must gain a thorough understanding of the existing literature concerning their field, as well as the theoretical frameworks and conceptual models that have shaped current research methodologies. In general, students should start with articles that have been published within the last 3-5 years, and then review less recent studies that are considered flagship works that have shaped the field in important ways. While reading through this research, students should stay organized with their notes, the conclusions they draw from their literature review, and how these conclusions impact their research study, as they will have to write about these topics in their dissertation.

Select a Research Advisor and Committee

One of the most important parts of students’ research process is selecting a dissertation advisor and committee. Students’ dissertation advisors are faculty members within the school’s EdD program who work closely with students to ensure that they select a research question and project that are manageable in scope, meet certain research and writing deadlines, and have the support and mentorship they need to succeed.

The dissertation committee is comprised of a group of faculty members and instructors who are qualified to read through and provide feedback on a student’s dissertation. The chair of the committee is a student’s dissertation advisor, and the student selects other members based off of their work and expertise in their area of research. Many schools have guidelines around the individuals students can select to be a part of their committee. For example, an EdD program may require students to select one more faculty member from within the EdD program (in addition to their faculty advisor), one individual outside of the department who works in a related field, and one subject matter expert from inside or outside the department who can give in-depth advice regarding the student’s research project. Students must obtain approval from their program for their committee member selections.

A student’s dissertation committee not only provides feedback and support on a student’s research, but also serves as a collective evaluator of a student’s research progress and final product. For example, the committee generally sets dissertation chapter completion and submission deadlines to keep students on track, and also listens to and evaluates students’ dissertation defense, which is a requirement for graduation.

Create and Defend Research Proposal

After students receive approval of their dissertation committee, they work individually and with their dissertation chair/advisor to develop a formal research proposal. The proposal typically includes the first three chapters of a student’s dissertation: the Introduction, the Literature Review chapter, and the Research Methodology chapter. In this proposal, students must outline their specific research query and its relevance to and impact on different spheres of education. They must also explain the work that has already been done in their area of research, their methodologies for the study they will conduct, and their tools and plans for analysis.

Once students have written these three chapters and formalized their research proposal, they must meet with their committee to present and defend their research proposal. This defense is meant to identify any issues with a student’s research objective, review of the literature, or study methodology, so that the student can address these issues prior to conducting their research.

Develop a Timeline for Research and Writing

Students work with their dissertation committee to establish timelines for the completion of certain chapters and milestones in their study (e.g. the conducting of surveys or the compilation and analysis of data or records). A reasonable timeline may have students writing the first three chapters during the fall term of their third year, and the fourth and fifth chapters during the spring term of the same year. However, dissertation timelines will vary depending on whether students are pursuing their degree full-time or part-time, how early in their program they are able to take the requisite research courses prior to starting their independent work, how soon they are able to identify a research question, and other factors.

Apply for Institutional Review Board (IRB) Approval

The Institutional Review Board protects the rights and well-being of human subjects of research studies by working to ensure their consent to certain research procedures, and assuring their ethical treatment during the research process. All EdD research projects must receive IRB approval before proceeding. The IRB approval application is generally comprised of any study subject consent forms; copies of any surveys, questionnaires, or other data collection methods and tools to be used; a completed application form; and proof of IRB Training completion. IRB Training is typically completed through an online course module that is delivered through the Collaborative Institutional Training Initiative (CITI) program.

Conduct Study and Analyze Results

Once students have received IRB approval, they are ready to proceed with their planned study. Data collection methods vary depending on the nature and scope of one’s research project, but may include sending out surveys, conducting interviews, conducting student or teacher assessments, compiling student performance metrics from public records, and other methods of collecting relevant data to try and answer their research query. Once students have gathered sufficient data, they move to the analysis of this data to try and find trends or patterns that help answer their research question. Throughout this process, students consult with their advisor and with members of their dissertation committee as necessary.

Complete Dissertation and Submit for Review and Revision

Once students have completed their analysis, they must write the Results and Analysis and Discussion and Conclusions sections of their dissertation. The Results and Analysis chapter is a straightforward explanation of one’s study results and the conclusions that can be drawn from them. The Discussion and Conclusions section places the study results in the context of the larger educational issue(s) affected by one’s research, makes recommendations for the application of one’s findings, and also provides suggestions for further research in the area of study. Upon the completion of a full dissertation manuscript, students submit their work to their committee for review and commentary. Students may go through several revisions and then final edits of their dissertation prior to their final defense and formal manuscript submission.

Conduct Dissertation Final Defense

A milestone in the EdD student’s graduate school career is the dissertation final defense, which is a formal presentation that students make to their dissertation committee, in which they explain their research objectives, methodology, and findings. During and after their presentation, committee members ask questions in an effort to identify any weaknesses, inconsistencies, or other issues in the student’s research. When faced with these questions, students must answer clearly and defend the validity of their research methods, results, and conclusions. After the presentation and questions are over, the committee confers to decide whether the student has passed his or her final defense and will receive the doctoral degree.

Before completing their dissertation defense, it is recommended that students prepare well in advance by attending the defenses of other students within the same program and discussing their dissertation manuscript with their advisor and asking any questions regarding what to expect during the defense. Students should craft a strong and well-organized presentation, and also anticipate questions that their committee members may ask them.

Submit Dissertation for Formal Review

The final step students need to take to complete their dissertation is to submit their fully edited manuscript for formal review by their dissertation committee, after making any necessary modifications in response to recommendations given during their dissertation defense. Some programs require students to publish their dissertation in an academic journal, which requires students to format their manuscript according to journal guidelines.

Department of History

Ph.d. program overview.

The Ph.D. program in History trains students in the skills of conducting original historical research and crafting original historical arguments. In the course of their work as historians, Brown scholars draw on a wide range of methods and engage with a variety of audiences. While training emphasizes the core skills of academic research, writing, and teaching at the college and university level, the program’s goals do not end there. Many Brown Ph.D. students explore teaching and writing for different settings and prepare for a breadth of careers that value the skills that obtaining a Ph.D. in History entails.

Students are expected to complete Brown’s Ph.D. program in five to six years. As a mid-sized program, the department values and cultivates attentive and hands-on faculty who work closely with students throughout their progress towards a degree. Critically, students in an entering cohort proceed through the program together, so that discussions across fields, geographies, and chronologies are built into the Ph.D. program.

Students accepted into the History Ph.D. program who remain in good standing are guaranteed funding for six years. Ph.D. students not supported by external fellowships work typically as teaching assistants in the second, third, and fifth (and, if relevant, a portion of the sixth) years of their program. There are also opportunities to apply for conference, research, and study grants either through the History Department or the Graduate School.

The information presented here is a summary of the Ph.D. program. For a more detailed description, see the Department of History Graduate Handbook. Prospective students should also read carefully the information supplied on the website of Brown’s Graduate School.

The Program is divided into two stages:

Stage 1: Coursework and preparation for the Preliminary Exams (Years 1-3)

During the first and second years, students take seminars that introduce the major historiographical questions and methodologies of various subfields and develop their research skills. They identify the three fields for their Preliminary Exams and begin preparation for the exams, which are usually taken in December of the third year. Students are expected to teach as teaching assistants in their second and third years.

History offers five types of Ph.D. courses, typically to be completed within the first three years of a student’s program:

1)    Required seminars (4): "History Now" features cutting-edge historical research and writing, including that being written by History faculty members; "The Roots of History" traces the development of the historical profession, focusing on the major methodological and theoretical landmarks in that development; an advanced workshop, "Writing History," guides students through the writing of a publishable paper; a Dissertation Prospectus Seminar culminates in the student’s defense of the dissertation plan and proposal.

2)    Field Seminars offer a broad overview of the historiography of particular fields (e.g., Early Modern Europe, Modern East Asia).

3)    Thematic Seminars provide opportunities to explore a particular theme or methodological frame from a transnational and transtemporal perspective.

4)    Special Topics Seminars focus on the historiography of a particular nation or region, historical "event," or historiographical debate. They allow for focused, close training, including in specialized skills and readings in languages other than English.

5)    Independent Study courses, by arrangement with the instructor, offer students, individually or in small groups, opportunities to explore special interests in depth.

In addition, students will receive course credit for attending "The Practice of History," a series of professionalization workshops that provide guidance in grant-writing, applying for jobs, developing inclusive teaching practices, constructing effective syllabuses, etc.

Students typically take four courses per semester. Up to two graduate courses (exclusive of language courses) may be taken outside the department.

A typical schedule looks like this:

* Can be filled in a number of ways, including a language course, a 1000-level class, an independent study, a 2000-level class, or with a placeholder independent study with the DGS (HIST2910)

Preliminary Examinations 

By the end of the first semester, students should have identified three fields (one major and two minor); these are usually subfields of the primary and secondary fields listed under Fields of Study ). These will be the areas examined in the Preliminary Examinations—three written and one oral exam—usually completed by the end of the fifth semester.

Language Requirement

Language requirements are set by the fields of study. They must be completed before the preliminary examinations are taken at the end of the fifth semester.

Stage 2: Prospectus and advancement to candidacy (Years 3-5/6)

After the successful completion of all coursework, the language requirement, and the preliminary examinations, the student, usually during the course of the sixth semester, develops a dissertation prospectus. Once the prospectus is approved by the student’s dissertation committee, the student devotes full effort (outside of work as a Teaching Assistant) to researching and writing the dissertation.

In the sixth semester, students take the Dissertation Prospectus Seminar, which provides a collaborative structure for the process of identifying viable dissertation projects, selecting a Dissertation Committee, articulating the project in the form of a dissertation prospectus, and, when appropriate, developing grant proposals based on the prospectus. The prospectus, in roughly 15 to 20 pages, states the dissertation topic, sets it in the context of the relevant secondary historical literature, explains the significance of the study, outlines the methodology to be followed, describes the types of primary sources to be used, and provides a tentative chapter outline, a bibliography, and a research plan. During the Dissertation Prospectus Defense, usually held in May or June, the Dissertation Committee reviews the prospectus and provides suggestions and advice to the student. Once the prospectus is approved, the student proceeds to conduct research on the dissertation.

Dissertation

Dissertations can vary significantly between students and among subfields. Students should consult regularly with their advisors during the dissertation research and writing process, to report progress and to ensure agreement on expectations for the dissertation. The most basic standard for a dissertation is that it makes an original contribution to the body of relevant scholarship in its field. The doctoral dissertation should be completed within four years after the student passes the preliminary examinations.

The Dissertation Defense is conducted by the graduate advisor and other members of the Dissertation Committee. Its purpose is to provide a forum for a general discussion of the dissertation—its strengths and weaknesses as a contribution to knowledge and its future prospects.  If the dissertation is approved by the Dissertation Committee, the student has completed the final requirement of the Ph.D. program and can prepare to graduate.

Candidates for the Ph.D. must normally demonstrate satisfactory performance as a Teaching Assistant in undergraduate courses at Brown, or in teaching at another institution approved by the department. A Teaching Assistant usually works as a grader and section discussion leader under the guidance of the faculty member teaching the course. Ph.D. students not supported by external fellowships typically work as Teaching Assistants in the second, third, and fifth years of their program, and one semester in their sixth year. Explanation of the rights and responsibilities of teaching assistants may be found in the Department of History Graduate Handbook.

The written exam for each individual field may consist of (1) a timed, written, closed or open book exam, (2) a long essay or series of shorter essays, or (3) a draft syllabus and one or several course lectures. (Other potential outcomes must be approved ahead of time by the DGS.) The written exam may be completed (1) when the student finishes reading for a field, leaving only the oral portion for December, or (2) immediately before the oral exam in December. The oral exam, which normally takes place in December of the third year, is two hours long and consists of all three exam committee members querying the student regarding the written exams, the field at large, and/or any materials from the exam list. For more details on the preliminary exams, see the History Graduate Student Handbook.

Summary of Exam Process

• May 19 : Fields Declaration Form submitted to the student’s primary advisor (who will normally be the chair of the exam committee), the DGS, and the graduate program administrator
• Summer: Students should initiate conversations with examiners regarding lists and procedures. 
• January : Preparation for the preliminarily exam should begin in earnest, continuing through the summer and fall. Students should enroll for an Independent Study in semester 4 with their primary advisor or other examiner (see above).
• March 31 : Submission of Fields Planning Form , along with drafts of the three field lists and a progress report on language and all other requirements
• September : Graduate program administrator circulates information about the oral portion of the exam.
• November : Graduate program administrator circulates schedules for the oral exams, along with all submitted written exam responses.
• Early to mid-December : Oral exams are conducted. 

Sample Exam Preparation Schedule Note : This is intended only to provide a rough framework for exam preparation; individual exam processes may vary, depending on examiner and student availability and preference.

• January : Initiate reading for Field 1 (usually major field, as part of IS)
• April : Complete written exam for Field 1
• May : Initiate reading for Field 2
• July : Complete written exam for Field 2
• August : Initiate reading for Field 3
• October : Complete written exam for Field 3
• November : Review Fields 1, 2, and 3 in preparation for oral exam

December : Complete oral exams

The capstone project of the Ph.D. program is the Doctoral Dissertation. The Department’s required core course sequence concludes with the Dissertation Prospectus Seminar, which students take in the sixth semester, usually after passing their Preliminary Exams.

The Dissertation Prospectus Seminar (spring semester of the third year) provides a shared structure for the process of identifying viable dissertation projects, selecting a dissertation committee, articulating the project in the form of a dissertation prospectus, and, where appropriate, developing grant proposals based on the prospectus. The dissertation committee, the selection of which is a requirement of the course, consists of a chair and at least two additional Brown faculty members. 

The dissertation committee will be responsible for evaluating the student's dissertation prospectus, to be presented no later than the end of the sixth semester. This usually takes the form of a dissertation prospectus defense, which is an important moment to bring together the dissertation committee to provide input and advice on the prospectus as well as the next steps of research and writing.

After passing the preliminary exams and obtaining approval of their dissertation prospectus by the dissertation committee, Ph.D. candidates are encouraged to proceed with speed and efficiency into the research process. During the research and writing of the thesis, it is the student's responsibility to regularly provide the graduate advisor with evidence of satisfactory progress towards completion. The doctoral dissertation should be completed within four years after the student passes the preliminary exams.

The department expects each student to have a dissertation defense The defense will normally be conducted by the graduate advisor and dissertation committee members, whether in person or via video conference. If the candidate wishes, other graduate students may attend and participate in the discussion.

A Dissertation Defense form must be filled out by the student and submitted to the Department staff. This form should be filed at the same time as the submission of the penultimate version of the dissertation, on March 15 for a May graduation, or no later than one month prior to the dissertation defense date if an October or February graduation. 

If the dissertation is approved by the dissertation committee, the student has completed the final requirement of the Ph.D. and is permitted to proceed with preparations for graduation. Students are permitted by the Graduate School to graduate (having fulfilled all requirements) at three points during the year: October, February, and May. Students who wish to take part in Commencement ceremonies may elect to walk in May following their graduation (or at the time of their graduation, if in May). Brown University Commencement usually takes place the Sunday before Memorial Day. There is a separate Graduate School Ceremony as well as a Department Ceremony that graduate students are especially encouraged to attend.

What's the Difference Between a PhD and a Doctorate?

Ria Ghosh ,

Aug 16, 2024 | PhD

Share it on:

PhD vs Doctorate degrees implies that students willing to pursue the career path of research and academics may pursue a PhD, and those who are looking for leadership and advanced roles may pursue a doctorate.

PhD vs Doctorate: The primary difference between a PhD and a Doctorate is that a PhD focuses on academic research while professional doctorate makes a significant and original contribution turning into a further professional practice.

A doctorate combines both coursework and a thesis of between 70,000 and 100,000 words. The PhD and Doctorate have academic requirements may be similar, but there are slight differences in career opportunities.

The difference between a PhD and a doctorate is that PhD programmes offer studies in a particular field with research aspects, providing opportunities in the academic field or any other field, including the government sector and doctorate programmes offer more advanced while a doctorate is a profession of leadership-focused and field-specified research, leading to even more progressive career paths.

The Doctorate degree is a graduate-level college degree for individuals aspiring to work in a more practical environment, like leadership and managerial positions. This degree is considered the terminal degree, as this is the final level of education a professional can achieve in their respective field. There are 2 types of doctorate degrees such as academic and professional. 

The professional doctorate is an applied doctorate with a specific profession, like medicine, surgery, and law. Here are some of the examples of the professional doctorate: 

• Doctor of Business Administration (DBA)
• Doctor of Dental Surgery (DDS)
• Doctor of Dental Medicine (DMD)
• Doctor of Podiatric Medicine (DPM)
• Doctor of Chiropractic (DC)
• Doctor of Veterinary Medicine (DVM)
• Doctor of Naturopathic Medicine (ND)
• Juris Doctor (JD)

An academic doctorate is often referred as the following titles: 

• Doctor of Philosophy (PhD)
• Doctor of Education (EdD)
• Doctor of Design (DDes)
• Doctor of Fine Arts (DFA)
• Doctor of Nursing Science (DNS)
• Doctor of Theology (ThD)

Difference between PhD and Doctorate

Learning about a PhD or doctorate which is better, can be bewildering for students willing to pursue higher education. 

PhD vs Doctorate in terms of research implies that the former is a particular type that majorly focuses on contribution to academics and original research, whereas the latter focuses on a broader category and comprises advanced degrees.

The purpose of a PhD is to conduct in-depth research through data analysis and assess related theories and ideas. A PhD student aims to test out their theories to contribute information and data findings to a specific discipline or field of study.

On the other hand, the main purpose of a Doctorate is to transform students into working professionals by providing them with practical knowledge in their preferred field of study. For working professionals, this degree helps to emphasize their credibility, influence and leadership capabilities.

The goal of a PhD student is to analyze theories accurately and create philosophical concepts in their field of study. They have to evaluate relevant information from contemporary and innovative sources to use in their research work. Finally, they must contribute to their field of study through their own research by analyzing current research material for informational gaps.

The goal and outcome of the Doctorate degree is to be able to apply academic knowledge to real-life situations and environments. This can be done when a student achieves a firm understanding of how to use existing solutions or create innovative solutions to solve complex problems.

The academic requirements for a PhD or Doctorate degree are almost similar. Aspiring students must have a Master’s degree with at least 55% aggregate marks in the field that is relevant to PhDs, or to the Doctorate. In some cases, candidates might require an Master of Philosophy (M.PHil) or Master of Psychology degree. There is also a selection process conducted by many educational institutions, where students need to appear for an entrance exam and interviews. Candidates having relevant working experience were given priority.

The duration of a PhD degree depends on various factors. The total time to complete the study can depend on the status of a student as a full or part-time student, timely completion of research stages, willingness to take up summer courses, etc. Hence, it can be expected for a student to complete the degree maximum within eight years, or a minimum of three to six years.

The time it takes to get a doctorate can depend on the specific course of study. Candidates can finish the degree within four to seven years if they are done with the initial academic requirements. Whereas, some educational institutions allow their students up to 10 years to complete the doctorate degree.

A PhD student has to submit a dissertation paper, which involves preparing, drafting and orally defending the argument of the dissertation in front of a committee of academic professionals. To achieve the required results, they have to do an extensive amount of research and documentation of the findings, literature, materials, reviews and conclusions.

To complete a doctorate program, a student has to draft a proposal that identifies and solves a problem. Based on this, they design a method to conduct their research and develop the solution. Similar to the PhD program, students must conduct extensive research, collect data, and defend their proposal orally in front of a committee.

PhD vs Doctorate Career Prospects

A PhD graduate can work in primary roles related to academics and research and other industries as well, such as Government and Nonprofits, Analysts, etc. This is because they have high expertise and opportunities in various career fields, including academics and research.

On the other hand, a doctorate is involved in advanced practice roles, including leadership roles in the fields of business, education, law, and medicine. They are well-suited for these roles as they have specific industry-centric knowledge that leads to more leadership roles and opportunities in specified sectors.

PhD vs Doctorate: What to Choose?

Candidates must have questions like "PhD or doctorate which is better", "Choosing between PhD and Doctorate", etc. Hence, here are some pointers that will help candidates to make a well-informed decision regarding this.

• Career Goals: Candidates must closely analyze their career goals while making the decision. They must think thoroughly about whether they want a career in academic research or opportunities for working in a practical environment.
• Budget: Students must also determine the costs of pursuing the degree program. They must know that the doctorate program is generally more expensive. For this, they need to compare and analyse both programs and select the one that best suits their academic goals and budget.
• Academic Progress: Aspirants must also consider how far along they are in their academic journey to decide between a Ph.D. vs. a doctorate. They must opt for the one that helps them achieve their career goals in the least amount of time.
• Coursework: Candidates must do thorough research on the coursework of their desired program to understand if that fits their career and academic interests or not. They can do so by researching about the professors, lectures, course offerings, academic opportunities, etc.
• Time Commitments: Students must be aware of the fact that both PhD and Doctorate degrees   require an extensive amount of time for completion.

Dissertation Watch: Developing Self-Evaluation Skills in Interprofessional Simulation Educators: A Multilevel Mixed-Methods Study

• Posted by by Antioch University
• August 20, 2024

Dana G. Trottier, in fulfilling the requirements of the PhD in Counselor Education & Supervision at Antioch’s Seattle campus, has written and published a dissertation titled, Developing Self-Evaluation Skills in Interprofessional Simulation Educators: A Multilevel Mixed-Methods Study.

Trottier’s multilevel mixed methods research examines self-evaluation skills for fellows in an interprofessional simulation fellowship program. Twelve interprofessional fellows and four faculty engaged in a three-phase study using video-assisted learning tools to explore the differences in self-evaluation (perceived performance) and faculty evaluation (actual performance) in developing debriefing skills. 

Trottier’s dissertation used quantitative and qualitative methods. For the quantitative component, he had fellows and faculty complete the DASH© tool to evaluate the quality of debriefing to help close the gaps between fellow self-evaluation and faculty evaluation. For the qualitative component, video-stimulated think-aloud and video-assisted debriefing the debriefer were utilized to understand how video-assisted learning tools contribute to self-evaluation skills from each level separately. 

Trottier used a combined focus group and thematic analysis to identify facilitators and barriers to self-evaluation. The results of this research indicated that fellows generally overestimate their skills performance, and video-assisted learning tools support the development of more realistic self-perception, eliminating underestimation and closing the gap between perceived and actual performance. He proposes a model for interprofessional collaboration, using scaffolded feedback practices to promote self-evaluation of skills and performance. This research contributes to the literature on counselor education, healthcare simulation, and health professions education.

Trottier is currently the Director of the Healthcare Simulation Fellowship Program at NYC Health + Hospitals/Simulation Center. Their research and curriculum development has focused on mitigating implicit bias in maternal substance use screening, forum theater to improve psychological safety among rapid response teams, video-assisted evaluation learning tools to develop interprofessional simulation educators, and debriefing experiential learning. He holds a master’s degree in Drama Therapy from New York University and a Certificate of Advanced Training in LGBTQ Healthcare from the Fenway Institute. Trottier serves as adjunct faculty at New York University (Drama Therapy). He has over 10 years of clinical experience working with individuals across the lifespan in a variety of settings, including acute care, medical, outpatient, private practice, PROS, community mental health, children’s enrichment, private organizations, and workplaces. Trottier is co-editor of the book Creative Arts Therapies and the LGBTQ Community.

Interpersonal violence victimisation of autistic adults: prevalence, correlates and impact

Research has consistently found high rates of victimisation amongst autistic children. There is emerging evidence that this disproportionate victimisation continues into adulthood, however this has not yet been thoroughly investigated. In this thesis, I aimed to examine the extent, nature and impact of interpersonal violence experiences among autistic adults and the factors that shape these experiences. In Chapter 1, I provide a brief overview of the prevalence and risk factors for interpersonal violence in the general population, theoretical approaches to understanding violence and a summary of the research that has been conducted in this area among autistic people. Chapter 2 outlines the methodological approach of this thesis, my reflections on the challenges and mitigations that occurred in the conduct of the research, a reflexivity statement and a summary of the role and impact of the autistic advisory group that I employed for the duration of this project. In Chapter 3, I conducted a systematic literature review to determine the current state of knowledge regarding the prevalence and correlates of interpersonal violence experienced by autistic people during adulthood. In Chapter 4, I conducted a secondary analysis using existing data collected as part of the Australian Longitudinal Study of Autistic Adults (ALSAA) to investigate the prevalence, traumatic impact and rates of disclosure of physical and sexual violence incidents reported by autistic adults in childhood and adulthood and compared this to non-autistic adults. I also examined whether there was a relationship between autistic traits and emotion regulation difficulties and exposure to sexual and physical violence. Chapters 5 to 7 present the findings from a mixed methods study designed for this thesis. In Chapter 5, I compared autistic and non-autistic adults on rates of sexual harassment, stalking and harassment, physical violence and sexual violence, and repeated and multiple violence during adulthood. I also compared gender patterns of violence among autistic and non-autistic adults and examined contextual factors. In Chapter 6, I investigated whether any individual characteristics that are common among autistic people (lower social competence, heightened compliance, emotion regulation difficulties or more ADHD features) were associated with poly-victimisation (experiencing multiple types of violence). In Chapter 7, I examined the nature and impact of interpersonal violence experiences, and possible factors shaping these experiences based on the first-hand accounts of autistic people. Finally, in Chapter 8, I discuss how the overall findings of this thesis contribute to the emerging evidence relating to the disproportionate victimisation of autistic people in adulthood by showing that (a) victimisation extends to a broad range of serious and criminal forms of violence which often go unreported, (b) gender differences in violence patterns appear narrowed among autistic people, (c) the impact of these experiences are exacerbated when reports of autistic victims of violence are dismissed or minimised, and (d) societal attitudes towards autism may contribute to increased vulnerability to violence and abuse. A multi-faceted approach is needed that goes beyond a focus on individual-level factors to address broader structural and systemic factors responsible for the disproportionate victimisation such as stigma, discrimination and epistemic injustice and includes educational strategies, public awareness campaigns, professional training, research efforts and policy change.
