Case studies are stories that are used as a teaching tool to show the application of a theory or concept to real situations. Dependent on the goal they are meant to fulfill, cases can be fact-driven and deductive where there is a correct answer, or they can be context driven where multiple solutions are possible. Various disciplines have employed case studies, including humanities, social sciences, sciences, engineering, law, business, and medicine. Good cases generally have the following features: they tell a good story, are recent, include dialogue, create empathy with the main characters, are relevant to the reader, serve a teaching function, require a dilemma to be solved, and have generality.

Instructors can create their own cases or can find cases that already exist. The following are some things to keep in mind when creating a case:

• What do you want students to learn from the discussion of the case?
• What do they already know that applies to the case?
• What are the issues that may be raised in discussion?
• How will the case and discussion be introduced?
• What preparation is expected of students? (Do they need to read the case ahead of time? Do research? Write anything?)
• What directions do you need to provide students regarding what they are supposed to do and accomplish?
• Do you need to divide students into groups or will they discuss as the whole class?
• Are you going to use role-playing or facilitators or record keepers? If so, how?
• What are the opening questions?
• How much time is needed for students to discuss the case?
• What concepts are to be applied/extracted during the discussion?
• How will you evaluate students?

Case method 1 teaching is an active form of instruction that focuses on a case and involves students learning by doing 2 3 . Cases are real or invented stories 4  that include “an educational message” or recount events, problems, dilemmas, theoretical or conceptual issue that requires analysis and/or decision-making.

Case-based teaching simulates real world situations and asks students to actively grapple with complex problems 5 6 This method of instruction is used across disciplines to promote learning, and is common in law, business, medicine, among other fields. See Table 1 below for a few types of cases and the learning they promote.

Case Method Teaching and Learning at Columbia

The case method is actively used in classrooms across Columbia, at the Morningside campus in the School of International and Public Affairs (SIPA), the School of Business, Arts and Sciences, among others, and at Columbia University Irving Medical campus.

Case method teaching has been found to improve student learning, to increase students’ perception of learning gains, and to meet learning objectives 8 9 . Faculty have noted the instructional benefits of cases including greater student engagement in their learning 10 , deeper student understanding of concepts, stronger critical thinking skills, and an ability to make connections across content areas and view an issue from multiple perspectives 11 . 

Through case-based learning, students are the ones asking questions about the case, doing the problem-solving, interacting with and learning from their peers, “unpacking” the case, analyzing the case, and summarizing the case. They learn how to work with limited information and ambiguity, think in professional or disciplinary ways, and ask themselves “what would I do if I were in this specific situation?”

The case method bridges theory to practice, and promotes the development of skills including: communication, active listening, critical thinking, decision-making, and metacognitive skills 12 , as students apply course content knowledge, reflect on what they know and their approach to analyzing, and make sense of a case. 

Though the case method has historical roots as an instructor-centered approach that uses the Socratic dialogue and cold-calling, it is possible to take a more learner-centered approach in which students take on roles and tasks traditionally left to the instructor. 

Cases are often used as “vehicles for classroom discussion” 13 . Students should be encouraged to take ownership of their learning from a case. Discussion-based approaches engage students in thinking and communicating about a case. Instructors can set up a case activity in which students are the ones doing the work of “asking questions, summarizing content, generating hypotheses, proposing theories, or offering critical analyses” 14 . 

The role of the instructor is to share a case or ask students to share or create a case to use in class, set expectations, provide instructions, and assign students roles in the discussion. Student roles in a case discussion can include: 

• discussion “starters” get the conversation started with a question or posing the questions that their peers came up with; 
• facilitators listen actively, validate the contributions of peers, ask follow-up questions, draw connections, refocus the conversation as needed; 
• recorders take-notes of the main points of the discussion, record on the board, upload to CourseWorks, or type and project on the screen; and 
• discussion “wrappers” lead a summary of the main points of the discussion. 

Prior to the case discussion, instructors can model case analysis and the types of questions students should ask, co-create discussion guidelines with students, and ask for students to submit discussion questions. During the discussion, the instructor can keep time, intervene as necessary (however the students should be doing the talking), and pause the discussion for a debrief and to ask students to reflect on what and how they learned from the case activity. 

Note: case discussions can be enhanced using technology. Live discussions can occur via video-conferencing (e.g., using Zoom ) or asynchronous discussions can occur using the Discussions tool in CourseWorks (Canvas) .

Table 2 includes a few interactive case method approaches. Regardless of the approach selected, it is important to create a learning environment in which students feel comfortable participating in a case activity and learning from one another. See below for tips on supporting student in how to learn from a case in the “getting started” section and how to create a supportive learning environment in the Guide for Inclusive Teaching at Columbia . 

Table 2. Strategies for Engaging Students in Case-Based Learning

Approaches to case teaching should be informed by course learning objectives, and can be adapted for small, large, hybrid, and online classes. Instructional technology can be used in various ways to deliver, facilitate, and assess the case method. For instance, an online module can be created in CourseWorks (Canvas) to structure the delivery of the case, allow students to work at their own pace, engage all learners, even those reluctant to speak up in class, and assess understanding of a case and student learning. Modules can include text, embedded media (e.g., using Panopto or Mediathread ) curated by the instructor, online discussion, and assessments. Students can be asked to read a case and/or watch a short video, respond to quiz questions and receive immediate feedback, post questions to a discussion, and share resources. 

For more information about options for incorporating educational technology to your course, please contact your Learning Designer .

To ensure that students are learning from the case approach, ask them to pause and reflect on what and how they learned from the case. Time to reflect  builds your students’ metacognition, and when these reflections are collected they provides you with insights about the effectiveness of your approach in promoting student learning.

Well designed case-based learning experiences: 1) motivate student involvement, 2) have students doing the work, 3) help students develop knowledge and skills, and 4) have students learning from each other.  

Designing a case-based learning experience should center around the learning objectives for a course. The following points focus on intentional design. 

Identify learning objectives, determine scope, and anticipate challenges. 

• Why use the case method in your course? How will it promote student learning differently than other approaches? 
• What are the learning objectives that need to be met by the case method? What knowledge should students apply and skills should they practice? 
• What is the scope of the case? (a brief activity in a single class session to a semester-long case-based course; if new to case method, start small with a single case). 
• What challenges do you anticipate (e.g., student preparation and prior experiences with case learning, discomfort with discussion, peer-to-peer learning, managing discussion) and how will you plan for these in your design? 
• If you are asking students to use transferable skills for the case method (e.g., teamwork, digital literacy) make them explicit. 

Determine how you will know if the learning objectives were met and develop a plan for evaluating the effectiveness of the case method to inform future case teaching. 

• What assessments and criteria will you use to evaluate student work or participation in case discussion? 
• How will you evaluate the effectiveness of the case method? What feedback will you collect from students? 
• How might you leverage technology for assessment purposes? For example, could you quiz students about the case online before class, accept assignment submissions online, use audience response systems (e.g., PollEverywhere) for formative assessment during class? 

Select an existing case, create your own, or encourage students to bring course-relevant cases, and prepare for its delivery

• Where will the case method fit into the course learning sequence? 
• Is the case at the appropriate level of complexity? Is it inclusive, culturally relevant, and relatable to students? 
• What materials and preparation will be needed to present the case to students? (e.g., readings, audiovisual materials, set up a module in CourseWorks). 

Plan for the case discussion and an active role for students

• What will your role be in facilitating case-based learning? How will you model case analysis for your students? (e.g., present a short case and demo your approach and the process of case learning) (Davis, 2009). 
• What discussion guidelines will you use that include your students’ input? 
• How will you encourage students to ask and answer questions, summarize their work, take notes, and debrief the case? 
• If students will be working in groups, how will groups form? What size will the groups be? What instructions will they be given? How will you ensure that everyone participates? What will they need to submit? Can technology be leveraged for any of these areas? 
• Have you considered students of varied cognitive and physical abilities and how they might participate in the activities/discussions, including those that involve technology? 

Student preparation and expectations

• How will you communicate about the case method approach to your students? When will you articulate the purpose of case-based learning and expectations of student engagement? What information about case-based learning and expectations will be included in the syllabus?
• What preparation and/or assignment(s) will students complete in order to learn from the case? (e.g., read the case prior to class, watch a case video prior to class, post to a CourseWorks discussion, submit a brief memo, complete a short writing assignment to check students’ understanding of a case, take on a specific role, prepare to present a critique during in-class discussion).

• The origins of this method can be traced to Harvard University where in 1870 the Law School began using cases to teach students how to think like lawyers using real court decisions. This was followed by the Business School in 1920 (Garvin, 2003). These professional schools recognized that lecture mode of instruction was insufficient to teach critical professional skills, and that active learning would better prepare learners for their professional lives. ↩

Making Learning Relevant With Case Studies

The open-ended problems presented in case studies give students work that feels connected to their lives.

To prepare students for jobs that haven’t been created yet, we need to teach them how to be great problem solvers so that they’ll be ready for anything. One way to do this is by teaching content and skills using real-world case studies, a learning model that’s focused on reflection during the problem-solving process. It’s similar to project-based learning, but PBL is more focused on students creating a product.

Case studies have been used for years by businesses, law and medical schools, physicians on rounds, and artists critiquing work. Like other forms of problem-based learning, case studies can be accessible for every age group, both in one subject and in interdisciplinary work.

You can get started with case studies by tackling relatable questions like these with your students:

• How can we limit food waste in the cafeteria?
• How can we get our school to recycle and compost waste? (Or, if you want to be more complex, how can our school reduce its carbon footprint?)
• How can we improve school attendance?
• How can we reduce the number of people who get sick at school during cold and flu season?

Addressing questions like these leads students to identify topics they need to learn more about. In researching the first question, for example, students may see that they need to research food chains and nutrition. Students often ask, reasonably, why they need to learn something, or when they’ll use their knowledge in the future. Learning is most successful for students when the content and skills they’re studying are relevant, and case studies offer one way to create that sense of relevance.

Teaching With Case Studies

Ultimately, a case study is simply an interesting problem with many correct answers. What does case study work look like in classrooms? Teachers generally start by having students read the case or watch a video that summarizes the case. Students then work in small groups or individually to solve the case study. Teachers set milestones defining what students should accomplish to help them manage their time.

During the case study learning process, student assessment of learning should be focused on reflection. Arthur L. Costa and Bena Kallick’s Learning and Leading With Habits of Mind gives several examples of what this reflection can look like in a classroom: 

Journaling: At the end of each work period, have students write an entry summarizing what they worked on, what worked well, what didn’t, and why. Sentence starters and clear rubrics or guidelines will help students be successful. At the end of a case study project, as Costa and Kallick write, it’s helpful to have students “select significant learnings, envision how they could apply these learnings to future situations, and commit to an action plan to consciously modify their behaviors.”

Interviews: While working on a case study, students can interview each other about their progress and learning. Teachers can interview students individually or in small groups to assess their learning process and their progress.

Student discussion: Discussions can be unstructured—students can talk about what they worked on that day in a think-pair-share or as a full class—or structured, using Socratic seminars or fishbowl discussions. If your class is tackling a case study in small groups, create a second set of small groups with a representative from each of the case study groups so that the groups can share their learning.

4 Tips for Setting Up a Case Study

1. Identify a problem to investigate: This should be something accessible and relevant to students’ lives. The problem should also be challenging and complex enough to yield multiple solutions with many layers.

2. Give context: Think of this step as a movie preview or book summary. Hook the learners to help them understand just enough about the problem to want to learn more.

3. Have a clear rubric: Giving structure to your definition of quality group work and products will lead to stronger end products. You may be able to have your learners help build these definitions.

4. Provide structures for presenting solutions: The amount of scaffolding you build in depends on your students’ skill level and development. A case study product can be something like several pieces of evidence of students collaborating to solve the case study, and ultimately presenting their solution with a detailed slide deck or an essay—you can scaffold this by providing specified headings for the sections of the essay.

Problem-Based Teaching Resources

There are many high-quality, peer-reviewed resources that are open source and easily accessible online.

• The National Center for Case Study Teaching in Science at the University at Buffalo built an online collection of more than 800 cases that cover topics ranging from biochemistry to economics. There are resources for middle and high school students.
• Models of Excellence , a project maintained by EL Education and the Harvard Graduate School of Education, has examples of great problem- and project-based tasks—and corresponding exemplary student work—for grades pre-K to 12.
• The Interdisciplinary Journal of Problem-Based Learning at Purdue University is an open-source journal that publishes examples of problem-based learning in K–12 and post-secondary classrooms.
• The Tech Edvocate has a list of websites and tools related to problem-based learning.

In their book Problems as Possibilities , Linda Torp and Sara Sage write that at the elementary school level, students particularly appreciate how they feel that they are taken seriously when solving case studies. At the middle school level, “researchers stress the importance of relating middle school curriculum to issues of student concern and interest.” And high schoolers, they write, find the case study method “beneficial in preparing them for their future.”

Case-Based Learning

This guide explores what case studies are, the value of using case studies as teaching tools, and how to implement them in your teaching.

What are case studies?

Case studies are stories that are used as a teaching tool to show the application of a theory or concept to real situations. Dependent on the goal they are meant to fulfill, cases can be fact-driven and deductive where there is a correct answer, or they can be context driven where multiple solutions are possible. Various disciplines have employed case studies, including humanities, social sciences, sciences, engineering, law, business, and medicine. Good cases generally have the following features: they tell a good story, are recent, include dialogue, create empathy with the main characters, are relevant to the reader, serve a teaching function, require a dilemma to be solved, and have generality.

How to use cases for teaching and learning

Instructors can create their own cases or can find cases that already exist. The following are some things to keep in mind when creating a case:

• What do you want students to learn from the discussion of the case?
• What do they already know that applies to the case?
• What are the issues that may be raised in discussion?
• How will the case and discussion be introduced?
• What preparation is expected of students? (Do they need to read the case ahead of time? Do research? Write anything?)
• What directions do you need to provide students regarding what they are supposed to do and accomplish?
• Do you need to divide students into groups or will they discuss as the whole class?
• Are you going to use role-playing or facilitators or record keepers? If so, how?
• What are the opening questions?
• How much time is needed for students to discuss the case?
• What concepts are to be applied/extracted during the discussion?
• How will you evaluate students?

To find other cases that already exist, try the following websites (if you know of other examples, please let us know and we will add them to this resource) :

• The National Center for Case Study Teaching in Science , University of Buffalo. SUNY-Buffalo maintains this set of links to other case studies on the web in disciplines ranging from engineering and ethics to sociology and business
• A Journal of Teaching Cases in Public Administration and Public Policy, University of Washington
• The American Anthropological Association’s Handbook on Ethical Issues in Anthropology , Chapter 3: Cases & Solutions  provides cases  in a format that asks the reader to solve each dilemma and includes the solutions used by the actual anthropologists. Comments by anthropologists who disagreed with the “solution” are also provided.

What the Case Study Method Really Teaches

• Nitin Nohria

Seven meta-skills that stick even if the cases fade from memory.

It’s been 100 years since Harvard Business School began using the case study method. Beyond teaching specific subject matter, the case study method excels in instilling meta-skills in students. This article explains the importance of seven such skills: preparation, discernment, bias recognition, judgement, collaboration, curiosity, and self-confidence.

During my decade as dean of Harvard Business School, I spent hundreds of hours talking with our alumni. To enliven these conversations, I relied on a favorite question: “What was the most important thing you learned from your time in our MBA program?”

• Nitin Nohria is the George F. Baker Jr. and Distinguished Service University Professor. He served as the 10th dean of Harvard Business School, from 2010 to 2020.

• Teaching with Cases

At professional schools (like Harvard’s Law, Business, Education, or Medical Schools), courses often adopt the so-called "case method" of teaching , in which students are confronted with real-world problems or scenarios involving multiple stakeholders and competing priorities. Most of the cases which faculty use with their students are written by professionals who have expertise in researching and writing in that genre, and for good reason—writing a truly masterful case, one which can engage students in hours of debate and deliberation, takes a lot of time and effort. It can be effective, nevertheless, for you to try implementing some aspects of the case-teaching approach in your class. Among the benefits which accrue to using case studies are the following:

• the fact that it gives your students the opportunity to "practice" a real-world application;
• the fact that it compels them (and you!) to reconstruct all of the divergent and convergent perspectives which different parties might bring to the scenario;
• the fact that it motivates your students to anticipate a wide range of possible responses which a reader might have; and
• the fact that it invites your students to indulge in metacognition as they revisit the process by which they became more knowledgeable about the scenario.

Features of an Effective Teaching Case

While no two case studies will be exactly alike, here are some of those principles:

• The case should illustrate what happens when a concept from the course could be, or has been, applied in the real world. Depending on the course, a “concept” might mean any one among a range of things, including an abstract principle, a theory, a tension, an issue, a method, an approach, or simply a way of thinking characteristic of an academic field. Whichever you choose, you should make sure to “ground” the case in a realistic setting early in the narrative, so that participants understand their role in the scenario.
• The case materials should include enough factual content and context to allow students to explore multiple perspectives. In order for participants to feel that they are encountering a real-world application of the course material, and that they have some freedom and agency in terms of how they interpret it, they need to be able to see the issue or problem from more than one perspective. Moreover, those perspectives need to seem genuine, and to be sketched in enough detail to seem complex. (In fact, it’s not a bad idea to include some “extraneous” information about the stakeholders involved in the case, so that students have to filter out things that seem relevant or irrelevant to them.) Otherwise, participants may fall back on picking obvious “winners” and “losers” rather than seeking creative, negotiated solutions that satisfy multiple stakeholders.
• The case materials should confront participants with a range of realistic constraints, hard choices, and authentic outcomes. If the case presumes that participants will all become omniscient, enjoy limitless resources, and succeed, they won’t learn as much about themselves as team-members and decision-makers as if they are forced to confront limitations, to make tough decisions about priorities, and to be prepared for unexpected results. These constraints and outcomes can be things which have been documented in real life, but they can also be things which the participants themselves surface in their deliberations.

• The activity should include space to reflect upon the decision-making process and the lessons of the case. Writing a case offers an opportunity to engage in multiple layers of reflection. For you, as the case writer, it is an occasion to anticipate how you (if you were the instructor) might create scenarios that are aligned with, and likely to meet the learning objectives of, a given unit of your course. For the participants whom you imagine using your case down the road, the case ideally should help them (1) to understand their own hidden assumptions, priorities, values, and biases better; and (2) to close the gap between their classroom learning and its potential real-world applications.

What is the Case Method?

The core pedagogy of Harvard Business School since the early 20th century, the case method boasts a unique ability to make complex concepts accessible and develop students’ leadership skills, all while creating an engaging intellectual atmosphere.

A “case” is a short narrative document – a story – that presents a particular challenge facing an individual or organization. Each case reflects the information available to decision-makers at the time, and builds to a particular decision point, but without revealing what decision was actually made. For each class, students are asked to read the case and to put themselves in the shoes of the actual decision-makers to consider what they themselves would have done given the information available at the time.

To help situate the decision, each case also provides background history on the most relevant issues and events leading up to the decision point. For example, a case that focuses on a decision facing Martin Luther King Jr. during the campaign for black voting rights in 1965 also traces the broader civil rights movement, as well as the history of segregation and black disenfranchisement in the U.S. since the Civil War.

In the classroom, the instructor poses questions to guide student discussion. These carefully designed questions are the key to any successful case-method course. An experienced case-method teacher is often thinking several steps ahead, anticipating what points and questions might be raised and standing ready with follow-up questions to guide the group. Active participation in class is essential to the case method’s success, and the grading metrics reflect its importance. Students quickly learn to speak up, to challenge each other, and to build on each other’s ideas.

Any professor or teacher can teach by the case method. Content expertise beyond the case itself is helpful but not required. To assist both experienced and new case-method teachers, each case has its own teaching plan: a flexible road-map for the instructor that suggests specific questions, strategies for eliciting key insights, and ideas for organizing student responses visually on a blackboard. For some cases, more extensive supporting documents known as “teaching notes” are available to fully brief the instructor on the relevant history and the multiple levels of questions he or she might consider.

“ I’ve never had this experience as a teacher before, and it's explicitly due to the case method — it's a game changer. ”

Case-based learning.

Case-based learning (CBL) is an established approach used across disciplines where students apply their knowledge to real-world scenarios, promoting higher levels of cognition (see Bloom’s Taxonomy ). In CBL classrooms, students typically work in groups on case studies, stories involving one or more characters and/or scenarios.  The cases present a disciplinary problem or problems for which students devise solutions under the guidance of the instructor. CBL has a strong history of successful implementation in medical, law, and business schools, and is increasingly used within undergraduate education, particularly within pre-professional majors and the sciences (Herreid, 1994). This method involves guided inquiry and is grounded in constructivism whereby students form new meanings by interacting with their knowledge and the environment (Lee, 2012).

There are a number of benefits to using CBL in the classroom. In a review of the literature, Williams (2005) describes how CBL: utilizes collaborative learning, facilitates the integration of learning, develops students’ intrinsic and extrinsic motivation to learn, encourages learner self-reflection and critical reflection, allows for scientific inquiry, integrates knowledge and practice, and supports the development of a variety of learning skills.

CBL has several defining characteristics, including versatility, storytelling power, and efficient self-guided learning.  In a systematic analysis of 104 articles in health professions education, CBL was found to be utilized in courses with less than 50 to over 1000 students (Thistlethwaite et al., 2012). In these classrooms, group sizes ranged from 1 to 30, with most consisting of 2 to 15 students.  Instructors varied in the proportion of time they implemented CBL in the classroom, ranging from one case spanning two hours of classroom time, to year-long case-based courses. These findings demonstrate that instructors use CBL in a variety of ways in their classrooms.

The stories that comprise the framework of case studies are also a key component to CBL’s effectiveness. Jonassen and Hernandez-Serrano (2002, p.66) describe how storytelling:

Is a method of negotiating and renegotiating meanings that allows us to enter into other’s realms of meaning through messages they utter in their stories,

Helps us find our place in a culture,

Allows us to explicate and to interpret, and

Facilitates the attainment of vicarious experience by helping us to distinguish the positive models to emulate from the negative model.

Neurochemically, listening to stories can activate oxytocin, a hormone that increases one’s sensitivity to social cues, resulting in more empathy, generosity, compassion and trustworthiness (Zak, 2013; Kosfeld et al., 2005). The stories within case studies serve as a means by which learners form new understandings through characters and/or scenarios.

CBL is often described in conjunction or in comparison with problem-based learning (PBL). While the lines are often confusingly blurred within the literature, in the most conservative of definitions, the features distinguishing the two approaches include that PBL involves open rather than guided inquiry, is less structured, and the instructor plays a more passive role. In PBL multiple solutions to the problem may exit, but the problem is often initially not well-defined. PBL also has a stronger emphasis on developing self-directed learning. The choice between implementing CBL versus PBL is highly dependent on the goals and context of the instruction.  For example, in a comparison of PBL and CBL approaches during a curricular shift at two medical schools, students and faculty preferred CBL to PBL (Srinivasan et al., 2007). Students perceived CBL to be a more efficient process and more clinically applicable. However, in another context, PBL might be the favored approach.

In a review of the effectiveness of CBL in health profession education, Thistlethwaite et al. (2012), found several benefits:

Students enjoyed the method and thought it enhanced their learning,

Instructors liked how CBL engaged students in learning,

CBL seemed to facilitate small group learning, but the authors could not distinguish between whether it was the case itself or the small group learning that occurred as facilitated by the case.

Other studies have also reported on the effectiveness of CBL in achieving learning outcomes (Bonney, 2015; Breslin, 2008; Herreid, 2013; Krain, 2016). These findings suggest that CBL is a vehicle of engagement for instruction, and facilitates an environment whereby students can construct knowledge.

Science – Students are given a scenario to which they apply their basic science knowledge and problem-solving skills to help them solve the case. One example within the biological sciences is two brothers who have a family history of a genetic illness. They each have mutations within a particular sequence in their DNA. Students work through the case and draw conclusions about the biological impacts of these mutations using basic science. Sample cases: You are Not the Mother of Your Children ; Organic Chemisty and Your Cellphone: Organic Light-Emitting Diodes ;   A Light on Physics: F-Number and Exposure Time

Medicine – Medical or pre-health students read about a patient presenting with specific symptoms. Students decide which questions are important to ask the patient in their medical history, how long they have experienced such symptoms, etc. The case unfolds and students use clinical reasoning, propose relevant tests, develop a differential diagnoses and a plan of treatment. Sample cases: The Case of the Crying Baby: Surgical vs. Medical Management ; The Plan: Ethics and Physician Assisted Suicide ; The Haemophilus Vaccine: A Victory for Immunologic Engineering

Public Health – A case study describes a pandemic of a deadly infectious disease. Students work through the case to identify Patient Zero, the person who was the first to spread the disease, and how that individual became infected.  Sample cases: The Protective Parent ; The Elusive Tuberculosis Case: The CDC and Andrew Speaker ; Credible Voice: WHO-Beijing and the SARS Crisis

Law – A case study presents a legal dilemma for which students use problem solving to decide the best way to advise and defend a client. Students are presented information that changes during the case.  Sample cases: Mortgage Crisis Call (abstract) ; The Case of the Unpaid Interns (abstract) ; Police-Community Dialogue (abstract)

Business – Students work on a case study that presents the history of a business success or failure. They apply business principles learned in the classroom and assess why the venture was successful or not. Sample cases: SELCO-Determining a path forward ; Project Masiluleke: Texting and Testing to Fight HIV/AIDS in South Africa ; Mayo Clinic: Design Thinking in Healthcare

Humanities - Students consider a case that presents a theater facing financial and management difficulties. They apply business and theater principles learned in the classroom to the case, working together to create solutions for the theater. Sample cases: David Geffen School of Drama

Recommendations

Finding and Writing Cases

Consider utilizing or adapting open access cases - The availability of open resources and databases containing cases that instructors can download makes this approach even more accessible in the classroom. Two examples of open databases are the Case Center on Public Leadership and Harvard Kennedy School (HKS) Case Program , which focus on government, leadership and public policy case studies.

• Consider writing original cases - In the event that an instructor is unable to find open access cases relevant to their course learning objectives, they may choose to write their own. See the following resources on case writing: Cooking with Betty Crocker: A Recipe for Case Writing ; The Way of Flesch: The Art of Writing Readable Cases ;   Twixt Fact and Fiction: A Case Writer’s Dilemma ; And All That Jazz: An Essay Extolling the Virtues of Writing Case Teaching Notes .

Implementing Cases

Take baby steps if new to CBL - While entire courses and curricula may involve case-based learning, instructors who desire to implement on a smaller-scale can integrate a single case into their class, and increase the number of cases utilized over time as desired.

Use cases in classes that are small, medium or large - Cases can be scaled to any course size. In large classes with stadium seating, students can work with peers nearby, while in small classes with more flexible seating arrangements, teams can move their chairs closer together. CBL can introduce more noise (and energy) in the classroom to which an instructor often quickly becomes accustomed. Further, students can be asked to work on cases outside of class, and wrap up discussion during the next class meeting.

Encourage collaborative work - Cases present an opportunity for students to work together to solve cases which the historical literature supports as beneficial to student learning (Bruffee, 1993). Allow students to work in groups to answer case questions.

Form diverse teams as feasible - When students work within diverse teams they can be exposed to a variety of perspectives that can help them solve the case. Depending on the context of the course, priorities, and the background information gathered about the students enrolled in the class, instructors may choose to organize student groups to allow for diversity in factors such as current course grades, gender, race/ethnicity, personality, among other items.  

Use stable teams as appropriate - If CBL is a large component of the course, a research-supported practice is to keep teams together long enough to go through the stages of group development: forming, storming, norming, performing and adjourning (Tuckman, 1965).

Walk around to guide groups - In CBL instructors serve as facilitators of student learning. Walking around allows the instructor to monitor student progress as well as identify and support any groups that may be struggling. Teaching assistants can also play a valuable role in supporting groups.

Interrupt strategically - Only every so often, for conversation in large group discussion of the case, especially when students appear confused on key concepts. An effective practice to help students meet case learning goals is to guide them as a whole group when the class is ready. This may include selecting a few student groups to present answers to discussion questions to the entire class, asking the class a question relevant to the case using polling software, and/or performing a mini-lesson on an area that appears to be confusing among students.  

Assess student learning in multiple ways - Students can be assessed informally by asking groups to report back answers to various case questions. This practice also helps students stay on task, and keeps them accountable. Cases can also be included on exams using related scenarios where students are asked to apply their knowledge.

The Case Study Teaching Method

It is easy to get confused between the case study method and the case method , particularly as it applies to legal education. The case method in legal education was invented by Christopher Columbus Langdell, Dean of Harvard Law School from 1870 to 1895. Langdell conceived of a way to systematize and simplify legal education by focusing on previous case law that furthered principles or doctrines. To that end, Langdell wrote the first casebook, entitled A Selection of Cases on the Law of Contracts , a collection of settled cases that would illuminate the current state of contract law. Students read the cases and came prepared to analyze them during Socratic question-and-answer sessions in class.

The Harvard Business School case study approach grew out of the Langdellian method. But instead of using established case law, business professors chose real-life examples from the business world to highlight and analyze business principles. HBS-style case studies typically consist of a short narrative (less than 25 pages), told from the point of view of a manager or business leader embroiled in a dilemma. Case studies provide readers with an overview of the main issue; background on the institution, industry, and individuals involved; and the events that led to the problem or decision at hand. Cases are based on interviews or public sources; sometimes, case studies are disguised versions of actual events or composites based on the faculty authors’ experience and knowledge of the subject. Cases are used to illustrate a particular set of learning objectives; as in real life, rarely are there precise answers to the dilemma at hand.

Our suite of free materials offers a great introduction to the case study method. We also offer review copies of our products free of charge to educators and staff at degree-granting institutions.

Case Study Teaching Method Improves Student Performance and Perceptions of Learning Gains †

Associated data.

• Appendix 1: Example assessment questions used to assess the effectiveness of case studies at promoting learning
• Appendix 2: Student learning gains were assessed using a modified version of the SALG course evaluation tool

Following years of widespread use in business and medical education, the case study teaching method is becoming an increasingly common teaching strategy in science education. However, the current body of research provides limited evidence that the use of published case studies effectively promotes the fulfillment of specific learning objectives integral to many biology courses. This study tested the hypothesis that case studies are more effective than classroom discussions and textbook reading at promoting learning of key biological concepts, development of written and oral communication skills, and comprehension of the relevance of biological concepts to everyday life. This study also tested the hypothesis that case studies produced by the instructor of a course are more effective at promoting learning than those produced by unaffiliated instructors. Additionally, performance on quantitative learning assessments and student perceptions of learning gains were analyzed to determine whether reported perceptions of learning gains accurately reflect academic performance. The results reported here suggest that case studies, regardless of the source, are significantly more effective than other methods of content delivery at increasing performance on examination questions related to chemical bonds, osmosis and diffusion, mitosis and meiosis, and DNA structure and replication. This finding was positively correlated to increased student perceptions of learning gains associated with oral and written communication skills and the ability to recognize connections between biological concepts and other aspects of life. Based on these findings, case studies should be considered as a preferred method for teaching about a variety of concepts in science courses.

INTRODUCTION

The case study teaching method is a highly adaptable style of teaching that involves problem-based learning and promotes the development of analytical skills ( 8 ). By presenting content in the format of a narrative accompanied by questions and activities that promote group discussion and solving of complex problems, case studies facilitate development of the higher levels of Bloom’s taxonomy of cognitive learning; moving beyond recall of knowledge to analysis, evaluation, and application ( 1 , 9 ). Similarly, case studies facilitate interdisciplinary learning and can be used to highlight connections between specific academic topics and real-world societal issues and applications ( 3 , 9 ). This has been reported to increase student motivation to participate in class activities, which promotes learning and increases performance on assessments ( 7 , 16 , 19 , 23 ). For these reasons, case-based teaching has been widely used in business and medical education for many years ( 4 , 11 , 12 , 14 ). Although case studies were considered a novel method of science education just 20 years ago, the case study teaching method has gained popularity in recent years among an array of scientific disciplines such as biology, chemistry, nursing, and psychology ( 5 – 7 , 9 , 11 , 13 , 15 – 17 , 21 , 22 , 24 ).

Although there is now a substantive and growing body of literature describing how to develop and use case studies in science teaching, current research on the effectiveness of case study teaching at meeting specific learning objectives is of limited scope and depth. Studies have shown that working in groups during completion of case studies significantly improves student perceptions of learning and may increase performance on assessment questions, and that the use of clickers can increase student engagement in case study activities, particularly among non-science majors, women, and freshmen ( 7 , 21 , 22 ). Case study teaching has been shown to improve exam performance in an anatomy and physiology course, increasing the mean score across all exams given in a two-semester sequence from 66% to 73% ( 5 ). Use of case studies was also shown to improve students’ ability to synthesize complex analytical questions about the real-world issues associated with a scientific topic ( 6 ). In a high school chemistry course, it was demonstrated that the case study teaching method produces significant increases in self-reported control of learning, task value, and self-efficacy for learning and performance ( 24 ). This effect on student motivation is important because enhanced motivation for learning activities has been shown to promote student engagement and academic performance ( 19 , 24 ). Additionally, faculty from a number of institutions have reported that using case studies promotes critical thinking, learning, and participation among students, especially in terms of the ability to view an issue from multiple perspectives and to grasp the practical application of core course concepts ( 23 ).

Despite what is known about the effectiveness of case studies in science education, questions remain about the functionality of the case study teaching method at promoting specific learning objectives that are important to many undergraduate biology courses. A recent survey of teachers who use case studies found that the topics most often covered in general biology courses included genetics and heredity, cell structure, cells and energy, chemistry of life, and cell cycle and cancer, suggesting that these topics should be of particular interest in studies that examine the effectiveness of the case study teaching method ( 8 ). However, the existing body of literature lacks direct evidence that the case study method is an effective tool for teaching about this collection of important topics in biology courses. Further, the extent to which case study teaching promotes development of science communication skills and the ability to understand the connections between biological concepts and everyday life has not been examined, yet these are core learning objectives shared by a variety of science courses. Although many instructors have produced case studies for use in their own classrooms, the production of novel case studies is time-consuming and requires skills that not all instructors have perfected. It is therefore important to determine whether case studies published by instructors who are unaffiliated with a particular course can be used effectively and obviate the need for each instructor to develop new case studies for their own courses. The results reported herein indicate that teaching with case studies results in significantly higher performance on examination questions about chemical bonds, osmosis and diffusion, mitosis and meiosis, and DNA structure and replication than that achieved by class discussions and textbook reading for topics of similar complexity. Case studies also increased overall student perceptions of learning gains and perceptions of learning gains specifically related to written and oral communication skills and the ability to grasp connections between scientific topics and their real-world applications. The effectiveness of the case study teaching method at increasing academic performance was not correlated to whether the case study used was authored by the instructor of the course or by an unaffiliated instructor. These findings support increased use of published case studies in the teaching of a variety of biological concepts and learning objectives.

Student population

This study was conducted at Kingsborough Community College, which is part of the City University of New York system, located in Brooklyn, New York. Kingsborough Community College has a diverse population of approximately 19,000 undergraduate students. The student population included in this study was enrolled in the first semester of a two-semester sequence of general (introductory) biology for biology majors during the spring, winter, or summer semester of 2014. A total of 63 students completed the course during this time period; 56 students consented to the inclusion of their data in the study. Of the students included in the study, 23 (41%) were male and 33 (59%) were female; 40 (71%) were registered as college freshmen and 16 (29%) were registered as college sophomores. To normalize participant groups, the same student population pooled from three classes taught by the same instructor was used to assess both experimental and control teaching methods.

Course material

The four biological concepts assessed during this study (chemical bonds, osmosis and diffusion, mitosis and meiosis, and DNA structure and replication) were selected as topics for studying the effectiveness of case study teaching because they were the key concepts addressed by this particular course that were most likely to be taught in a number of other courses, including biology courses for both majors and nonmajors at outside institutions. At the start of this study, relevant existing case studies were freely available from the National Center for Case Study Teaching in Science (NCCSTS) to address mitosis and meiosis and DNA structure and replication, but published case studies that appropriately addressed chemical bonds and osmosis and diffusion were not available. Therefore, original case studies that addressed the latter two topics were produced as part of this study, and case studies produced by unaffiliated instructors and published by the NCCSTS were used to address the former two topics. By the conclusion of this study, all four case studies had been peer-reviewed and accepted for publication by the NCCSTS ( http://sciencecases.lib.buffalo.edu/cs/ ). Four of the remaining core topics covered in this course (macromolecules, photosynthesis, genetic inheritance, and translation) were selected as control lessons to provide control assessment data.

To minimize extraneous variation, control topics and assessments were carefully matched in complexity, format, and number with case studies, and an equal amount of class time was allocated for each case study and the corresponding control lesson. Instruction related to control lessons was delivered using minimal slide-based lectures, with emphasis on textbook reading assignments accompanied by worksheets completed by students in and out of the classroom, and small and large group discussion of key points. Completion of activities and discussion related to all case studies and control topics that were analyzed was conducted in the classroom, with the exception of the take-home portion of the osmosis and diffusion case study.

Data collection and analysis

This study was performed in accordance with a protocol approved by the Kingsborough Community College Human Research Protection Program and the Institutional Review Board (IRB) of the City University of New York (CUNY IRB reference 539938-1; KCC IRB application #: KCC 13-12-126-0138). Assessment scores were collected from regularly scheduled course examinations. For each case study, control questions were included on the same examination that were similar in number, format, point value, and difficulty level, but related to a different topic covered in the course that was of similar complexity. Complexity and difficulty of both case study and control questions were evaluated using experiential data from previous iterations of the course; the Bloom’s taxonomy designation and amount of material covered by each question, as well as the average score on similar questions achieved by students in previous iterations of the course was considered in determining appropriate controls. All assessment questions were scored using a standardized, pre-determined rubric. Student perceptions of learning gains were assessed using a modified version of the Student Assessment of Learning Gains (SALG) course evaluation tool ( http://www.salgsite.org ), distributed in hardcopy and completed anonymously during the last week of the course. Students were presented with a consent form to opt-in to having their data included in the data analysis. After the course had concluded and final course grades had been posted, data from consenting students were pooled in a database and identifying information was removed prior to analysis. Statistical analysis of data was conducted using the Kruskal-Wallis one-way analysis of variance and calculation of the R 2 coefficient of determination.

Teaching with case studies improves performance on learning assessments, independent of case study origin

To evaluate the effectiveness of the case study teaching method at promoting learning, student performance on examination questions related to material covered by case studies was compared with performance on questions that covered material addressed through classroom discussions and textbook reading. The latter questions served as control items; assessment items for each case study were compared with control items that were of similar format, difficulty, and point value ( Appendix 1 ). Each of the four case studies resulted in an increase in examination performance compared with control questions that was statistically significant, with an average difference of 18% ( Fig. 1 ). The mean score on case study-related questions was 73% for the chemical bonds case study, 79% for osmosis and diffusion, 76% for mitosis and meiosis, and 70% for DNA structure and replication ( Fig. 1 ). The mean score for non-case study-related control questions was 60%, 54%, 60%, and 52%, respectively ( Fig. 1 ). In terms of examination performance, no significant difference between case studies produced by the instructor of the course (chemical bonds and osmosis and diffusion) and those produced by unaffiliated instructors (mitosis and meiosis and DNA structure and replication) was indicated by the Kruskal-Wallis one-way analysis of variance. However, the 25% difference between the mean score on questions related to the osmosis and diffusion case study and the mean score on the paired control questions was notably higher than the 13–18% differences observed for the other case studies ( Fig. 1 ).

Asterisk indicates p < 0.05.

Case study teaching increases student perception of learning gains related to core course objectives

Student learning gains were assessed using a modified version of the SALG course evaluation tool ( Appendix 2 ). To determine whether completing case studies was more effective at increasing student perceptions of learning gains than completing textbook readings or participating in class discussions, perceptions of student learning gains for each were compared. In response to the question “Overall, how much did each of the following aspects of the class help your learning?” 82% of students responded that case studies helped a “good” or “great” amount, compared with 70% for participating in class discussions and 58% for completing textbook reading; only 4% of students responded that case studies helped a “small amount” or “provided no help,” compared with 2% for class discussions and 22% for textbook reading ( Fig. 2A ). The differences in reported learning gains derived from the use of case studies compared with class discussion and textbook readings were statistically significant, while the difference in learning gains associated with class discussion compared with textbook reading was not statistically significant by a narrow margin ( p = 0.051).

The case study teaching method increases student perceptions of learning gains. Student perceptions of learning gains are indicated by plotting responses to the question “How much did each of the following activities: (A) Help your learning overall? (B) Improve your ability to communicate your knowledge of scientific concepts in writing? (C) Improve your ability to communicate your knowledge of scientific concepts orally? (D) Help you understand the connections between scientific concepts and other aspects of your everyday life?” Reponses are represented as follows: Helped a great amount (black bars); Helped a good amount (dark gray bars); Helped a moderate amount (medium gray bars); Helped a small amount (light gray bars); Provided no help (white bars). Asterisk indicates p < 0.05.

To elucidate the effectiveness of case studies at promoting learning gains related to specific course learning objectives compared with class discussions and textbook reading, students were asked how much each of these methods of content delivery specifically helped improve skills that were integral to fulfilling three main course objectives. When students were asked how much each of the methods helped “improve your ability to communicate knowledge of scientific concepts in writing,” 81% of students responded that case studies help a “good” or “great” amount, compared with 63% for class discussions and 59% for textbook reading; only 6% of students responded that case studies helped a “small amount” or “provided no help,” compared with 8% for class discussions and 21% for textbook reading ( Fig. 2B ). When the same question was posed about the ability to communicate orally, 81% of students responded that case studies help a “good” or “great” amount, compared with 68% for class discussions and 50% for textbook reading, while the respective response rates for helped a “small amount” or “provided no help,” were 4%, 6%, and 25% ( Fig. 2C ). The differences in learning gains associated with both written and oral communication were statistically significant when completion of case studies was compared with either participation in class discussion or completion of textbook readings. Compared with textbook reading, class discussions led to a statistically significant increase in oral but not written communication skills.

Students were then asked how much each of the methods helped them “understand the connections between scientific concepts and other aspects of your everyday life.” A total of 79% of respondents declared that case studies help a “good” or “great” amount, compared with 70% for class discussions and 57% for textbook reading ( Fig. 2D ). Only 4% stated that case studies and class discussions helped a “small amount” or “provided no help,” compared with 21% for textbook reading ( Fig. 2D ). Similar to overall learning gains, the use of case studies significantly increased the ability to understand the relevance of science to everyday life compared with class discussion and textbook readings, while the difference in learning gains associated with participation in class discussion compared with textbook reading was not statistically significant ( p = 0.054).

Student perceptions of learning gains resulting from case study teaching are positively correlated to increased performance on examinations, but independent of case study author

To test the hypothesis that case studies produced specifically for this course by the instructor were more effective at promoting learning gains than topically relevant case studies published by authors not associated with this course, perceptions of learning gains were compared for each of the case studies. For both of the case studies produced by the instructor of the course, 87% of students indicated that the case study provided a “good” or “great” amount of help to their learning, and 2% indicated that the case studies provided “little” or “no” help ( Table 1 ). In comparison, an average of 85% of students indicated that the case studies produced by an unaffiliated instructor provided a “good” or “great” amount of help to their learning, and 4% indicated that the case studies provided “little” or “no” help ( Table 1 ). The instructor-produced case studies yielded both the highest and lowest percentage of students reporting the highest level of learning gains (a “great” amount), while case studies produced by unaffiliated instructors yielded intermediate values. Therefore, it can be concluded that the effectiveness of case studies at promoting learning gains is not significantly affected by whether or not the course instructor authored the case study.

Case studies positively affect student perceptions of learning gains about various biological topics.

Finally, to determine whether performance on examination questions accurately predicts student perceptions of learning gains, mean scores on examination questions related to case studies were compared with reported perceptions of learning gains for those case studies ( Fig. 3 ). The coefficient of determination (R 2 value) was 0.81, indicating a strong, but not definitive, positive correlation between perceptions of learning gains and performance on examinations, suggesting that student perception of learning gains is a valid tool for assessing the effectiveness of case studies ( Fig. 3 ). This correlation was independent of case study author.

Perception of learning gains but not author of case study is positively correlated to score on related examination questions. Percentage of students reporting that each specific case study provided “a great amount of help” to their learning was plotted against the point difference between mean score on examination questions related to that case study and mean score on paired control questions. Positive point differences indicate how much higher the mean scores on case study-related questions were than the mean scores on paired control questions. Black squares represent case studies produced by the instructor of the course; white squares represent case studies produced by unaffiliated instructors. R 2 value indicates the coefficient of determination.

The purpose of this study was to test the hypothesis that teaching with case studies produced by the instructor of a course is more effective at promoting learning gains than using case studies produced by unaffiliated instructors. This study also tested the hypothesis that the case study teaching method is more effective than class discussions and textbook reading at promoting learning gains associated with four of the most commonly taught topics in undergraduate general biology courses: chemical bonds, osmosis and diffusion, mitosis and meiosis, and DNA structure and replication. In addition to assessing content-based learning gains, development of written and oral communication skills and the ability to connect scientific topics with real-world applications was also assessed, because these skills were overarching learning objectives of this course, and classroom activities related to both case studies and control lessons were designed to provide opportunities for students to develop these skills. Finally, data were analyzed to determine whether performance on examination questions is positively correlated to student perceptions of learning gains resulting from case study teaching.

Compared with equivalent control questions about topics of similar complexity taught using class discussions and textbook readings, all four case studies produced statistically significant increases in the mean score on examination questions ( Fig. 1 ). This indicates that case studies are more effective than more commonly used, traditional methods of content delivery at promoting learning of a variety of core concepts covered in general biology courses. The average increase in score on each test item was equivalent to nearly two letter grades, which is substantial enough to elevate the average student performance on test items from the unsatisfactory/failing range to the satisfactory/passing range. The finding that there was no statistical difference between case studies in terms of performance on examination questions suggests that case studies are equally effective at promoting learning of disparate topics in biology. The observations that students did not perform significantly less well on the first case study presented (chemical bonds) compared with the other case studies and that performance on examination questions did not progressively increase with each successive case study suggests that the effectiveness of case studies is not directly related to the amount of experience students have using case studies. Furthermore, anecdotal evidence from previous semesters of this course suggests that, of the four topics addressed by cases in this study, DNA structure and function and osmosis and diffusion are the first and second most difficult for students to grasp. The lack of a statistical difference between case studies therefore suggests that the effectiveness of a case study at promoting learning gains is not directly proportional to the difficulty of the concept covered. However, the finding that use of the osmosis and diffusion case study resulted in the greatest increase in examination performance compared with control questions and also produced the highest student perceptions of learning gains is noteworthy and could be attributed to the fact that it was the only case study evaluated that included a hands-on experiment. Because the inclusion of a hands-on kinetic activity may synergistically enhance student engagement and learning and result in an even greater increase in learning gains than case studies that lack this type of activity, it is recommended that case studies that incorporate this type of activity be preferentially utilized.

Student perceptions of learning gains are strongly motivating factors for engagement in the classroom and academic performance, so it is important to assess the effect of any teaching method in this context ( 19 , 24 ). A modified version of the SALG course evaluation tool was used to assess student perceptions of learning gains because it has been previously validated as an efficacious tool ( Appendix 2 ) ( 20 ). Using the SALG tool, case study teaching was demonstrated to significantly increase student perceptions of overall learning gains compared with class discussions and textbook reading ( Fig. 2A ). Case studies were shown to be particularly useful for promoting perceived development of written and oral communication skills and for demonstrating connections between scientific topics and real-world issues and applications ( Figs. 2B–2D ). Further, student perceptions of “great” learning gains positively correlated with increased performance on examination questions, indicating that assessment of learning gains using the SALG tool is both valid and useful in this course setting ( Fig. 3 ). These findings also suggest that case study teaching could be used to increase student motivation and engagement in classroom activities and thus promote learning and performance on assessments. The finding that textbook reading yielded the lowest student perceptions of learning gains was not unexpected, since reading facilitates passive learning while the class discussions and case studies were both designed to promote active learning.

Importantly, there was no statistical difference in student performance on examinations attributed to the two case studies produced by the instructor of the course compared with the two case studies produced by unaffiliated instructors. The average difference between the two instructor-produced case studies and the two case studies published by unaffiliated instructors was only 3% in terms of both the average score on examination questions (76% compared with 73%) and the average increase in score compared with paired control items (14% compared with 17%) ( Fig. 1 ). Even when considering the inherent qualitative differences of course grades, these differences are negligible. Similarly, the effectiveness of case studies at promoting learning gains was not significantly affected by the origin of the case study, as evidenced by similar percentages of students reporting “good” and “great” learning gains regardless of whether the case study was produced by the course instructor or an unaffiliated instructor ( Table 1 ).

The observation that case studies published by unaffiliated instructors are just as effective as those produced by the instructor of a course suggests that instructors can reasonably rely on the use of pre-published case studies relevant to their class rather than investing the considerable time and effort required to produce a novel case study. Case studies covering a wide range of topics in the sciences are available from a number of sources, and many of them are free access. The National Center for Case Study Teaching in Science (NCCSTS) database ( http://sciencecases.lib.buffalo.edu/cs/ ) contains over 500 case studies that are freely available to instructors, and are accompanied by teaching notes that provide logistical advice and additional resources for implementing the case study, as well as a set of assessment questions with a password-protected answer key. Case study repositories are also maintained by BioQUEST Curriculum Consortium ( http://www.bioquest.org/icbl/cases.php ) and the Science Case Network ( http://sciencecasenet.org ); both are available for use by instructors from outside institutions.

It should be noted that all case studies used in this study were rigorously peer-reviewed and accepted for publication by the NCCSTS prior to the completion of this study ( 2 , 10 , 18 , 25 ); the conclusions of this study may not apply to case studies that were not developed in accordance with similar standards. Because case study teaching involves skills such as creative writing and management of dynamic group discussion in a way that is not commonly integrated into many other teaching methods, it is recommended that novice case study teachers seek training or guidance before writing their first case study or implementing the method. The lack of a difference observed in the use of case studies from different sources should be interpreted with some degree of caution since only two sources were represented in this study, and each by only two cases. Furthermore, in an educational setting, quantitative differences in test scores might produce meaningful qualitative differences in course grades even in the absence of a p value that is statistically significant. For example, there is a meaningful qualitative difference between test scores that result in an average grade of C− and test scores that result in an average grade of C+, even if there is no statistically significant difference between the two sets of scores.

In the future, it could be informative to confirm these findings using a larger cohort, by repeating the study at different institutions with different instructors, by evaluating different case studies, and by directly comparing the effectiveness of the case studying teaching method with additional forms of instruction, such as traditional chalkboard and slide-based lecturing, and laboratory-based activities. It may also be informative to examine whether demographic factors such as student age and gender modulate the effectiveness of the case study teaching method, and whether case studies work equally well for non-science majors taking a science course compared with those majoring in the subject. Since the topical material used in this study is often included in other classes in both high school and undergraduate education, such as cell biology, genetics, and chemistry, the conclusions of this study are directly applicable to a broad range of courses. Presently, it is recommended that the use of case studies in teaching undergraduate general biology and other science courses be expanded, especially for the teaching of capacious issues with real-world applications and in classes where development of written and oral communication skills are key objectives. The use of case studies that involve hands-on activities should be emphasized to maximize the benefit of this teaching method. Importantly, instructors can be confident in the use of pre-published case studies to promote learning, as there is no indication that the effectiveness of the case study teaching method is reliant on the production of novel, customized case studies for each course.

Case Teaching

The professional real world is complex and filled with uncertainty. Rather than avoiding this complexity, case-based instruction centers around cases that tell the stories of real-life protagonists facing difficult decisions. Cases often end with a straightforward question: Which path should the protagonist take? To answer this question, students carefully read the case and its documents before class. They then spend class time discussing the context, analyzing the data, and debating potential courses of action the protagonist could take. As a facilitator of the conversation, the case instructor tracks and guides the conversation, pushing students to further clarify their ideas, teasing out disagreements, and introducing useful frameworks for analyzing the case. The end of a case discussion usually involves a "reveal," where the actual outcome is shared and students have an opportunity to reflect on their predictions. For these reasons, case-based discussion classrooms are an exciting mix: they are intensely grounded in specifics yet centered around an open-ended question. Effective case teaching instructors prepare intensely for sessions but try to always follow their students’ lead as well. 

How do you plan a case-session that will cover the key concepts but is flexible enough to follow a spontaneous conversation? How can instructors effectively follow up with students to ensure their students’ ideas have been clearly articulated and explored? How can student disagreement be harnessed for deeper understanding? How can instructors make sure that all students have an opportunity to be heard in the classroom discussion? In these videos, featured instructor Julie Battilana discusses her approach and strategies for using case teaching with graduate students across the university.

What does the research say.

• Merseth provides the historical context behind the case-based teaching method ( 1991 )

Seen from the lens of constructivism, the use of case studies requires active engagement from students. Because constructivism posits that students actively construct their understanding, instructors using case studies should consider how to build flexibility into their lessons to allow for active student engagement ( Sudzina, 1997 )

Case teaching is linked to student learning gains and positive student perceptions about their learning ( Bonney, 2015 )

How to... Write a teaching case study

• What is a teaching case study?

A discussion-based case study is an education tool to facilitate learning about, and analysis of, a real-world situation.

A case study provides a well-researched and compelling narrative about an individual, or a group of people, that needs to make a decision in an organisational setting.

The case study narrative includes relevant information about the situation, and gives multiple perspectives on the problem or decision that needs to be taken, but does not provide analysis, conclusions, or a solution.

Which publication would suit my case study.

Read about getting ready to publish and visit the Emerald Cases Hub for courses and guides on writing case studies and teaching notes.

Teaching cases expose students to real-world business dilemmas in different cultural contexts.

Students are expected to read the case study and prepare an argument about the most appropriate course of action or recommendation, which can be debated in a facilitated case study class session, or documented in a case study assignment or examination.

A case teaching note, containing recent and relevant theoretical and managerial frameworks, will be published alongside the teaching case, and can be used to demonstrate the links between course content and the case situation to support teaching of the case method.

Teaching case studies have a distinctive literary style: they are written in the third person, in the past tense, and establish an objectivity of core dilemmas in the case.

We have gathered some top tips for you to think about as your write your case study.

Collect information

Cases can be based on primary or secondary data; however, carrying out interviews with the protagonist and others in the organisation, where possible, often results in a better and more balanced case study.

Make sure that you have all the materials you will need before you start the writing process. This will speed up the actual process. Most case studies have a mixture of primary and secondary sources to help capture the spirit of the protagonist.

Structure the narrative

Tell the story in chronological order and in the past tense. Identify and establish the central protagonist and their dilemma in the first paragraph and summarise the dilemma again at the end of the case.

Develop the protagonist

Ensure the protagonist is a well-developed character and that students can identify with their motivations throughout the case.

Get permission

When you submit your case study and teaching note, you must include signed permission from the relevant protagonist or company featured in the case and for any material for which you don’t own the copyright. 

Be clear on your teaching objective

The case method offers a variety of class participation methods, such as discussion, role-play, presentation, or examination. Decide which method best suits the case you want to write. 

Identify case lead author

You might want to consider writing your case study in partnership with colleagues. However, if you are writing a case with other people you need to make sure that the case reads as one voice.

You do not have to share the work evenly. Instead, play to your individual strengths: one author might be better at data analysis, one a better writer. Agree and clarify the order of appearance of authors. This is very important since this cannot be changed after publication.

Write a thorough teaching note

A well-written case study needs an equally well-written teaching note to allow instructors to adopt the case without the need for additional research. The standard teaching note provides key materials such as learning objectives, sample questions and answers, and more. See 'What to include in your teaching note' to produce effective teaching note for your case.

Writing a teaching case requires a distinctive literary style; it should be written in the third person, in the past tense, and establish objectivity of the core dilemmas in the case.

To begin with, a case has to have a hook: an overriding issue that pulls various parts together, a managerial issue or decision that requires urgent attention. 

The trick is to present the story so that the hook is not immediately apparent but ‘discovered’ by students putting the relevant pieces together. More importantly, the hook must be linked to a particular concept, theory, or methodology. 

A teaching case reflects the ambiguity of the situation and need not have a single outcome, as the intent is to create a dialogue with students, encourage critical thinking and research, and evaluate recommendations.

Research cases are a methodology used to support research findings and add to the body of theoretical knowledge, and as such are more academically-focused and evidence-based.

Writing a case study

How to write & structure a case

• Write in the past tense
• Identify and establish an issue/problem which can be used to teach a concept or theory

The opening paragraph should make clear:

• Who the main protagonist is 
• Who the key decision maker is 
• What the nature of the problem or issue is 
• When the case took place, including specific dates 
• Why the issue or problem arose

The body of the case should:

• Tell the whole story – usually in a chronological order 
• Typically contain general background on business environment, company background, and the details of the specific issue(s) faced by the company 
• Tell more than one side of the story so that students can think of competing alternatives

The concluding paragraph should:

• Provide a short synthesis of the case to reiterate the main issues, or even to raise new questions

Before you start, choose where to publish your case study and familiarise yourself with the style and formatting requirements.

Get ready to publish  

What to include in your teaching note

Case synopsis.

Provide a brief summary (approximately 150-200 words) describing the case setting and key issues. Include:

• Name of the organisation
• Time span of the case study
• Details of the protagonist
• The dilemma facing the protagonist
• Sub-field of academia the case is designed to teach (e.g., market segmentation in the telecommunications sector).

Target audience

Clearly identify the appropriate audience for the case (e.g., undergraduate, graduate, or both).  Consider:

• Possible courses where the case can be used
• Level of difficulty
• Specific pre-requisites
• Discipline(s) for which the case is most relevant

If there are multiple target audiences, discuss different teaching strategies.

Top tip: remember that the deciding factor for most instructors looking to find a case for their classroom is relevancy. Working with a specific audience in mind and sharing guidance on case usage helps develop the applicability of your case.

Learning objectives

Set a minimum of one objective for a compact case study and three to four for a longer case. Your objectives should be specific and reflective of the courses you suggest your case be taught in. Make it clear what students can expect to learn from reading the case.

Top tip: Good learning objectives should cover not only basic understanding of the context and issues presented in the case, but also include a few more advanced goals such as analysis and evaluation of the case dilemma.

Research methods

Outline the types of data used to develop the case, how this data was gathered, and whether any names/details/etc. within the case have been disguised. Please note that you will need to obtain consent from the case protagonist/organisation if primary data has been used. Cases based on secondary data (i.e., any information that is publicly available) are not required to obtain consent.

Teaching plan and objectives

Provide a breakdown of the classroom discussion time into sections. Include a brief description of the opening and closing 10-15 minutes, as well as challenging case discussion questions with comprehensive sample answers.

Provide instructors a detailed breakdown of how you would teach the case in 90 minutes. Include:

• Brief description of the opening 10-15 minutes.
• Suggested class time, broken down by topics, assignment questions, and activities.
• Brief description of the closing 10-15 minutes. Reinforce the learning objectives and reveal what actually happened, if applicable

Assignment questions and answers

Include a set of challenging assignment questions that align with the teaching objectives and relate to the dilemma being faced in the case.

Successful cases will provide:

• Three to five questions aligned to the learning objectives.
• A combination of closed, open-ended, and even controversial questions to create discussion.
• Questions that prompt students to consider a dilemma from all angles.

Successful sample answers should:

• Provide an example of an outstanding (A+) response to each question. To illustrate the full range of potential answers, good teaching notes often go on to provide examples of marginal and even incorrect responses as well.
• Draw from recent literature, theory, or research findings to analyse the case study.
• Reflect the reality that a case may not necessarily have a single correct answer by highlighting a diversity of opinions and approaches.

Supporting material

Supporting materials can include any additional information or resources that supplement the experience of using your case. Examples of these materials include  such as worksheets, videos, reading lists, reference materials, etc. If you are including classroom activities as part of your teaching note, please provide detailed instructions on how to direct these activities.

Test & learn

When you have finished writing your case study and teaching note, test them!

Try them out in class to see if students have enough information to thoughtfully address the case dilemma, if the teaching note supports an engaged class discussion, and if the teaching note assignments/lesson plan timing are appropriate. Revise as needed based on the class experience before submitting.

Case studies.

The teaching business case studies available here are narratives that facilitate class discussion about a particular business or management issue. Teaching cases are meant to spur debate among students rather than promote a particular point of view or steer students in a specific direction.  Some of the case studies in this collection highlight the decision-making process in a business or management setting. Other cases are descriptive or demonstrative in nature, showcasing something that has happened or is happening in a particular business or management environment. Whether decision-based or demonstrative, case studies give students the chance to be in the shoes of a protagonist. With the help of context and detailed data, students can analyze what they would and would not do in a particular situation, why, and how.

Case Studies

Case studies can be used to help students understand simple and complex issues. They typically are presented to the students as a situation or scenario which is guided by questions such as “What would you do in this situation?” or “How would you solve this problem?” Successful case studies focus on problem situations relevant to course content and which are relevant “both to the interests and experience level of learners” (Illinois Online Network, 2007).

Case studies can be simple problems where students “work out” a solution to more complex scenarios which require role playing and elaborate planning. Case studies typically involve teams although cases can be undertaken individually. Because case studies often are proposed to not have “one right answer” (Kowalski, Weaver, Henson, 1998, p. 4), some students may be challenged to think alternatively than their peers. However, when properly planned, case studies can effectively engage students in problem solving and deriving creative solutions.

The Penn State University’s Teaching and Learning with Technology unit suggests the following elements when planning case studies for use in the classroom.

Case studies actively involve students as they work on issues found in “real-life” situations and, with careful planning, can be used in all academic disciplines.

• Real-World Scenario. Cases are generally based on real world situations, although some facts may be changed to simplify the scenario or “protect the innocent.”
• Supporting Data and Documents. Effective case assignments typically provide real world situations for student to analyze. These can be simple data tables, links to URLs, quoted statements or testimony, supporting documents, images, video, audio, or any appropriate material.
• Open-Ended Problem. Most case assignments require students to answer an open-ended question or develop a solution to an open-ended problem with multiple potential solutions. Requirements can range from a one-paragraph answer to a fully developed team action plan, proposal or decision. (Penn State University, 2006, para. 2).

Most case assignments require students to answer an open-ended question or develop a solution to an open-ended problem with multiple potential solutions.

Instructor Tasks

To help you get started using case studies in the classroom, a number of tasks should be considered. Following this list are tasks to help you prepare students as they participate in the case study.

• Identify a topic that is based on real-world situations
• Develop the case that will challenge students’ current knowledge of the topic
• Link the case to one (or more) of the course goals or objectives
• Provide students with case study basic information before asking them to work on the case
• Prepare necessary data, information, that will help students come up with a solution
• Discuss how this case would relate to real life and career situations
• Place students in teams in which participants have differing views and opinions to better challenge them in discussing possible solutions to the case
• Review team dynamics with the students (prepare an outline of team rules and roles)
• Inform students that they are to find a solution to the case based on their personal experiences, the knowledge gained in class, and challenge one another to solve the problem

Student Tasks

• Determine team member roles and identify a strategic plan to solve the case
• Brainstorm and prepare questions to further explore the case
• Read and critically analyze any data provided by the instructor, discuss the facts related to the case, identify and discuss the relationship of further problems within the case
• Listen to and be open to viewpoints expressed by each member of the team
• Assess, refine, and condense solutions that are presented
• Prepare findings as required by the instructor

Case studies provide students with scenarios in which they can begin to think about their understanding and solutions to problems found in real-world situations. When carefully planned, case studies will challenge students’ critical thinking and problem solving skills in a safe and open learning environment. Case studies can help students analyze and find solutions to complex problems with foresight and confidence.

Teaching excellence & educational innovation, case studies, what are case studies.

Case studies are stories. They present realistic, complex, and contextually rich situations and often involve a dilemma, conflict, or problem that one or more of the characters in the case must negotiate.

A good case study, according to Professor Paul Lawrence is:

“the vehicle by which a chunk of reality is brought into the classroom to be worked over by the class and the instructor. A good case keeps the class discussion grounded upon some of the stubborn facts that must be faced in real life situations.”

(quoted in Christensen, 1981)

Although they have been used most extensively in the teaching of medicine, law and business, case studies can be an effective teaching tool in any number of disciplines. As an instructional strategy, case studies have a number of virtues. They “bridge the gap between theory and practice and between the academy and the workplace” (Barkley, Cross, and Major 2005, p.182). They also give students practice identifying the parameters of a problem, recognizing and articulating positions, evaluating courses of action, and arguing different points of view.

Case studies vary in length and detail, and can be used in a number of ways, depending on the case itself and on the instructor’s goals.

• They can be short (a few paragraphs) or long (e.g. 20+ pages).
• They can be used in lecture-based or discussion-based classes.
• They can be real, with all the detail drawn from actual people and circumstances, or simply realistic.
• They can provide all the relevant data students need to discuss and resolve the central issue, or only some of it, requiring students to identify, and possibly fill in (via outside research), the missing information.
• They can require students to examine multiple aspects of a problem, or just a circumscribed piece.
• They can require students to propose a solution for the case or simply to identify the parameters of the problem.

Finding or creating cases

It is possible to write your own case studies, although it is not a simple task. The material for a case study can be drawn from your own professional experiences (e.g., negotiating a labor dispute at a local corporation or navigating the rocky shoals of a political campaign), from current events (e.g., a high-profile medical ethics case or a diplomatic conundrum), from historical sources (e.g., a legal debate or military predicament), etc. It is also possible to find published cases from books and on-line case study collections. Whatever the source, an effective case study is one that, according to Davis (1993):

• tells a “real” and engaging story
• raises a thought-provoking issue
• has elements of conflict
• promotes empathy with the central characters
• lacks an obvious or clear-cut right answer
• encourages students to think and take a position
• portrays actors in moments of decision
• provides plenty of data about character, location, context, actions
• is relatively concise

Using case studies

How you use case studies will depend on the goals, as well as on the format, of your course. If it is a large lecture course, for example, you might use a case study to illustrate and enrich the lecture material. (An instructor lecturing on principles of marketing, for example, might use the case of a particular company or product to explore marketing issues and dilemmas in a real-life context.) Also in a large class you might consider breaking the class into small groups or pairs to discuss a relevant case. If your class is a smaller, discussion-format course, you will be able to use more detailed and complex cases, to explore the perspectives introduced in the case in greater depth, and perhaps integrate other instructional strategies, such as role playing or debate. Regardless of the format in which you employ case studies, it is important that you, as the instructor, know all the issues involved in the case, prepare questions and prompts in advance, and anticipate where students might run into problems. Finally, consider who your students are and how you might productively draw on their backgrounds, experiences, personalities, etc., to enhance the discussion. While there are many variations in how case studies can be used, these six steps provide a general framework for how to lead a case-based discussion:

• Give students ample time to read and think about the case. If the case is long, assign it as homework with a set of questions for students to consider (e.g., What is the nature of the problem the central character is facing? What are some possible courses of action? What are the potential obstacles?)
• Introduce the case briefly and provide some guidelines for how to approach it. Clarify how you want students to think about the case (e.g., “Approach this case as if you were the presiding judge” or “You are a consultant hired by this company. What would you recommend?”) Break down the steps you want students to take in analyzing the case (e.g., “First, identify theconstraints each character in the case was operating under and the opportunities s/he had. Second, evaluate the decisions each character made and their implications. Finally, explain what you would have done differently and why.”). If you would like students to disregard or focus on certain information, specify that as well (e.g., “I want you to ignore the political affiliation of the characters described and simply distinguish their positions on stem-cell research as they are articulated here.”)
• Create groups and monitor them to make sure everyone is involved. Breaking the full class into smaller groups gives individual students more opportunities for participation and interaction. However, small groups can drift off track if you do not provide structure. Thus, it is a good idea to make the task of the group very concrete and clear (e.g., “You are to identify three potential courses of action and outline the pros and cons of each from a public relations standpoint”). You may also want to designate roles within each group: for example, one individual might be charged with keeping the others on task and watching the time; a second individual’s role might be to question the assumptions or interpretations of the group and probe for deeper analysis; a third individual’s role might be to record the group’s thoughts and report their decision to the class.  Alternatively, group members could be assigned broad perspectives (e.g., liberal, conservative, libertarian) to represent, or asked to speak for the various “stake-holders” in the case study.
• Have groups present their solutions/reasoning: If groups know they are responsible for producing something (a decision, rationale, analysis) to present to the class, they will approach the discussion with greater focus and seriousness. Write their conclusions on the board so that you can return to them in the discussion that follows.
•  Ask questions for clarification and to move discussion to another level. One of the challenges for a case-based discussion leader is to guide the discussion and probe for deeper analysis without over-directing. As the discussion unfolds, ask questions that call for students to examine their own assumptions, substantiate their claims, provide illustrations, etc.
• Synthesize issues raised. Be sure to bring the various strands of the discussion back together at the end, so that students see what they have learned and take those lessons with them. The job of synthesizing need not necessarily fall to the instructor, however; one or more students can be given this task.

Some variations on this general method include having students do outside research (individually or in groups) to bring to bear on the case in question, and comparing the actual outcome of a real-life dilemma to the solutions generated in class.

Kovin was struggling. He had lost his friend and partner the year before, and after their decades of partnership, taking over as CEO had made sense. But he could feel the tension in the senior management meeting. The team were enjoying the benefits of their commercial success –   they could attract talent, offer competitive salaries, develop more meaningful patents. But at what cost? Could they really still consider themselves a non-profit social enterprise? 

In the age of AI and Co-Pilot, the teaching case is gaining attention as a useful teaching tool. It not only consolidates lessons around central analytical themes, but also tests students’ analytical and interpretation skills. 

• Flip students’ presentations for more in-depth learning
• How to enhance teaching skills in a multidisciplinary environment
• Using experiential learning to teach international relations

A teaching case like this one brings real-world difficulties into the classroom, allowing students to apply what they’ve learned and solve problems. This case tells the story of anti-apartheid activist-turned-optometrist Kovin Naidoo, who finds himself leading a multinational social enterprise after the death of his partner. He struggles to balance his deeply held commitments to social change with the benefits of a fast-commercialising organisation. Studying this, students experience CEO-level tensions balancing profit and purpose, and work through how to balance competing value systems.

How do teaching cases work?

In the classroom, the lecturer introduces the case, describing the main protagonist, the context that they are operating in, and the dilemma that they are faced with. Teaching cases are not short of drama. They typically end on a cliffhanger, that nail-biting “now what?” moment, which students must then solve. Like a detective in a novel, students piece together the main facts, identify the red herrings, and through this process apply theoretical frameworks. Teaching cases are wonderful tools for critical thinking , synthesis and analysis.

For many years, the teaching case was seen as the domain of law and business schools. But steady work by publishers such as Emerald, IVEY, Harvard, Yale and the Case Centre has seen the scope of cases widening. 

What they have in common is a commitment to developing cases that transport students to different contexts, where they can immerse themselves in the detail of the problem and apply their learnings, across a range of disciplines. It is this DNA that makes them a useful tool in the AI learning world.

Cases contextualise and tailor our curriculum. In doing so, they are an anchor in our efforts to build nuanced teaching materials, providing alternatives to standard scenarios which, when repeated, risk one-dimensional, monocausal teaching.

Because of their focus on different situations, they contribute to inclusivity . Not only do they provide contextual variation but they engage with core concepts in a multitude of ways to facilitate learning . They allow us to use storytelling to address difficult topics that have the potential to marginalise or exclude. They encourage simulation and group work and create a dialogue between theory and practice , both teaching processes that contribute to professional relevance . As a result, students are immersed in problem-based, action-oriented learning techniques, which results in them being “ engaged in, and structuring their own learning ” – one of the pillars of inclusive teaching practice .

But it is the teaching note that is the lecturer’s friend. It introduces new pedagogy and approaches. Anchored in Bloom’s Taxonomy , it builds the teaching narrative, specifying the learning outcomes and how theoretical frameworks can be taught.

We are seeing innovations in case writing as the format gains popularity, such as:

• Short cases: Harvard is pioneering cases of 800 words (the length of this article) with a snappy dilemma. These can be fictional or drawn from secondary literature, building an informed narrative around a figure they can relate to. Taylor Swift is the focus of this case, for example, which requires little preparation time and sparks lively discussion. 
• Visual cases: We’ve been seeing comic book-style teaching notes that encourage storyboarding and description of both theory and process. Visual cases encourage broad discussion as students read between the lines, stimulated by both the style of graphics and minimised narrative. IMD’s Netflix: streaming wars and IBS’ Turbulence on the Tarmac are stylistically different, setting a different tone for discussion and debate.   
• Multimedia cases: Animation or short-form interviews that students can interact with are becoming common in teaching cases. Role-playing can range from the classic Oxford-style debate, where students develop opposing arguments, to materials such as this animation by IE Business School, which allows chronological learning across a historical timeline. 
• Raw teaching cases encourage students to research the dilemma that they are presented with. These cases are crisp in their presentation of the dilemma, and require students to then research and investigate the problem and solution. Pioneered by Yale, Raw Cases teach students how to synthesise information. Examples include this case on SELCO , and this debate-style approach to analysing the  Systems of Exchange framework.
• Students writing teaching cases as assignments: The NACRA community and our colleague Maria Ballesteros-Solas have developed the idea of putting students in the driving seat .  Here, students write a teaching case and note as an assignment. It requires students to research a dilemma and establish theoretical links   –   a creative process that encourages deep analysis and application of theory to practice.

Teaching cases are not new but the questions educators are grappling with on the use of AI have refocused our attention on the value that they bring to the classroom. They bring real-world dilemmas for students to think through, where the applied nature of the work means that there is no one-size-fits-all response. By encouraging group work and interactive and inclusive teaching practice, they help us as teachers contextualise our content and create opportunities for rich, structured debate and embedded learning.

Flash 15: Interrupted Case Study

Do you want students to go beyond surface-level learning while tapping into their curiosity? The interrupted case study is a teaching activity in which the instructor provides groups of students with a problem-based scenario in scaffolded chunks, periodically pausing for questions that tap into students' critical thinking.

In this 15-minute micro session video, you’ll learn about interrupted case studies, how you could implement it in your teaching context, and the modifications you could make to make this technique fit your teaching needs.

The interrupted case study is a teaching activity in which the instructor provides groups of students with a problem-based scenario in scaffolded chunks. On this video, you will see:

• What the approach is and the research that supports it.
• How to implement.
• How to adapt it to different teaching contexts.
• How to use a planning tool to help you implement.

Why is this teaching technique effective?

Researchers have found that interrupted case studies i ncrease engagement because they use real-life scenarios that makes the learning relevant to students’ career goals; a llows instructors to address misconceptions about course content in real time; c reates a safe environment for student risk-taking, as they develop a comfort for speculation and being incorrect; and p romotes an inclusive learning environment by providing additional structure to the conversation and supporting those students who may be more hesitant to engage in general discussion.

Accelerated ambitions: living lessons from the CASE More report

The CASE More report was unveiled at CEAC 2023, analysing a decade of giving to higher education and how this informs the future. Digging deep into ten years of data and interrogating the experience of higher education thought leaders and responses to a sector-wide survey, we shared evidence-informed recommendations for the sector – including for how different kinds of institutions can make the best of the cards they are dealt by their history. In this session we will explore the action that has followed the publication of the report, and illuminate three stand-out recommendations for institutions across Europe. (1) Engaging academic and institutional leaders; (2) the design and delivery of inspiring supporter journeys; and (3) growing legacies. We’ll explore the evidence and lessons in each area, and colleagues from the University of York, the University of Manchester and Imperial College London will share institutional case studies. Join us as we mine these vital areas of institutional advancement, inviting contributions and questions – and look onward together at predictions for the decade ahead.
