What the Case Study Method Really Teaches

by Nitin Nohria

Summary .   

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?”

Creating effective scenarios, case studies and role plays

Printable Version (PDF)

Scenarios, case studies and role plays are examples of active and collaborative teaching techniques that research confirms are effective for the deep learning needed for students to be able to remember and apply concepts once they have finished your course. See  Research Findings on University Teaching Methods .

Typically you would use case studies, scenarios and role plays for higher-level learning outcomes that require application, synthesis, and evaluation (see  Writing Outcomes or Learning Objectives ; scroll down to the table).

The point is to increase student interest and involvement, and have them practice application by making choices and receive feedback on them, and refine their understanding of concepts and practice in your discipline.

These types of activities provide the following research-based benefits: (Shaw, 3-5)

• They provide concrete examples of abstract concepts, facilitate the development through practice of analytical skills, procedural experience, and decision making skills through application of course concepts in real life situations. This can result in deep learning and the appreciation of differing perspectives.
• They can result in changed perspectives, increased empathy for others, greater insights into challenges faced by others, and increased civic engagement.
• They tend to increase student motivation and interest, as evidenced by increased rates of attendance, completion of assigned readings, and time spent on course work outside of class time.
• Studies show greater/longer retention of learned materials.
• The result is often better teacher/student relations and a more relaxed environment in which the natural exchange of ideas can take place. Students come to see the instructor in a more positive light.
• They often result in better understanding of complexity of situations. They provide a good forum for a large volume of orderly written analysis and discussion.

There are benefits for instructors as well, such as keeping things fresh and interesting in courses they teach repeatedly; providing good feedback on what students are getting and not getting; and helping in standing and promotion in institutions that value teaching and learning.

Outcomes and learning activity alignment

The learning activity should have a clear, specific skills and/or knowledge development purpose that is evident to both instructor and students. Students benefit from knowing the purpose of the exercise, learning outcomes it strives to achieve, and evaluation methods. The example shown in the table below is for a case study, but the focus on demonstration of what students will know and can do, and the alignment with appropriate learning activities to achieve those abilities applies to other learning activities.

(Smith, 18)

What’s the difference?

Scenarios are typically short and used to illustrate or apply one main concept. The point is to reinforce concepts and skills as they are taught by providing opportunity to apply them. Scenarios can also be more elaborate, with decision points and further scenario elaboration (multiple storylines), depending on responses. CETL has experience developing scenarios with multiple decision points and branching storylines with UNB faculty using PowerPoint and online educational software.

Case studies

Case studies are typically used to apply several problem-solving concepts and skills to a detailed situation with lots of supporting documentation and data. A case study is usually more complex and detailed than a scenario. It often involves a real-life, well documented situation and the students’ solutions are compared to what was done in the actual case. It generally includes dialogue, creates identification or empathy with the main characters, depending on the discipline. They are best if the situations are recent, relevant to students, have a problem or dilemma to solve, and involve principles that apply broadly.

Role plays can be short like scenarios or longer and more complex, like case studies, but without a lot of the documentation. The idea is to enable students to experience what it may be like to see a problem or issue from many different perspectives as they assume a role they may not typically take, and see others do the same.

Foundational considerations

Typically, scenarios, case studies and role plays should focus on real problems, appropriate to the discipline and course level.

They can be “well-structured” or “ill-structured”:

• Well-structured  case studies, problems and scenarios can be simple or complex or anything in-between, but they have an optimal solution and only relevant information is given, and it is usually labelled or otherwise easily identified.
• Ill-structured  case studies, problems and scenarios can also be simple or complex, although they tend to be complex. They have relevant and irrelevant information in them, and part of the student’s job is to decide what is relevant, how it is relevant, and to devise an evidence-based solution to the problem that is appropriate to the context and that can be defended by argumentation that draws upon the student’s knowledge of concepts in the discipline.

Well-structured problems would be used to demonstrate understanding and application. Higher learning levels of analysis, synthesis and evaluation are better demonstrated by ill-structured problems.

Scenarios, case studies and role plays can be  authentic  or  realistic :

• Authentic  scenarios are actual events that occurred, usually with personal details altered to maintain anonymity. Since the events actually happened, we know that solutions are grounded in reality, not a fictionalized or idealized or simplified situation. This makes them “low transference” in that, since we are dealing with the real world (although in a low-stakes, training situation, often with much more time to resolve the situation than in real life, and just the one thing to work on at a time), not much after-training adjustment to the real world is necessary.
• By contrast,  realistic  scenarios are often hypothetical situations that may combine aspects of several real-world events, but are artificial in that they are fictionalized and often contain ideal or simplified elements that exist differently in the real world, and some complications are missing. This often means they are easier to solve than real-life issues, and thus are “high transference” in that some after-training adjustment is necessary to deal with the vagaries and complexities of the real world.

Scenarios, case studies and role plays can be  high  or  low fidelity :

High vs. low fidelity:  Fidelity has to do with how much a scenario, case study or role play is like its corresponding real world situation. Simplified, well-structured scenarios or problems are most appropriate for beginners. These are low-fidelity, lacking a lot of the detail that must be struggled with in actual practice. As students gain experience and deeper knowledge, the level of complexity and correspondence to real-world situations can be increased until they can solve high fidelity, ill-structured problems and scenarios.

Further details for each

Scenarios can be used in a very wide range of learning and assessment activities. Use in class exercises, seminars, as a content presentation method, exam (e.g., tell students the exam will have four case studies and they have to choose two—this encourages deep studying). Scenarios help instructors reflect on what they are trying to achieve, and modify teaching practice.

For detailed working examples of all types, see pages 7 – 25 of the  Psychology Applied Learning Scenarios (PALS) pdf .

The contents of case studies should: (Norton, 6)

• Connect with students’ prior knowledge and help build on it.
• Be presented in a real world context that could plausibly be something they would do in the discipline as a practitioner (e.g., be “authentic”).
• Provide some structure and direction but not too much, since self-directed learning is the goal. They should contain sufficient detail to make the issues clear, but with enough things left not detailed that students have to make assumptions before proceeding (or explore assumptions to determine which are the best to make). “Be ambiguous enough to force them to provide additional factors that influence their approach” (Norton, 6).
• Should have sufficient cues to encourage students to search for explanations but not so many that a lot of time is spent separating relevant and irrelevant cues. Also, too many storyline changes create unnecessary complexity that makes it unnecessarily difficult to deal with.
• Be interesting and engaging and relevant but focus on the mundane, not the bizarre or exceptional (we want to develop skills that will typically be of use in the discipline, not for exceptional circumstances only). Students will relate to case studies more if the depicted situation connects to personal experiences they’ve had.
• Help students fill in knowledge gaps.

Role plays generally have three types of participants: players, observers, and facilitator(s). They also have three phases, as indicated below:

Briefing phase:  This stage provides the warm-up, explanations, and asks participants for input on role play scenario. The role play should be somewhat flexible and customizable to the audience. Good role descriptions are sufficiently detailed to let the average person assume the role but not so detailed that there are so many things to remember that it becomes cumbersome. After role assignments, let participants chat a bit about the scenarios and their roles and ask questions. In assigning roles, consider avoiding having visible minorities playing “bad guy” roles. Ensure everyone is comfortable in their role; encourage students to play it up and even overact their role in order to make the point.

Play phase:  The facilitator makes seating arrangements (for players and observers), sets up props, arranges any tech support necessary, and does a short introduction. Players play roles, and the facilitator keeps things running smoothly by interjecting directions, descriptions, comments, and encouraging the participation of all roles until players keep things moving without intervention, then withdraws. The facilitator provides a conclusion if one does not arise naturally from the interaction.

Debriefing phase:  Role players talk about their experience to the class, facilitated by the instructor or appointee who draws out the main points. All players should describe how they felt and receive feedback from students and the instructor. If the role play involved heated interaction, the debriefing must reconcile any harsh feelings that may otherwise persist due to the exercise.

Five Cs of role playing  (AOM, 3)

Control:  Role plays often take on a life of their own that moves them in directions other than those intended. Rehearse in your mind a few possible ways this could happen and prepare possible intervention strategies. Perhaps for the first role play you can play a minor role to give you and “in” to exert some control if needed. Once the class has done a few role plays, getting off track becomes less likely. Be sensitive to the possibility that students from different cultures may respond in unforeseen ways to role plays. Perhaps ask students from diverse backgrounds privately in advance for advice on such matters. Perhaps some of these students can assist you as co-moderators or observers.

Controversy:  Explain to students that they need to prepare for situations that may provoke them or upset them, and they need to keep their cool and think. Reiterate the learning goals and explain that using this method is worth using because it draws in students more deeply and helps them to feel, not just think, which makes the learning more memorable and more likely to be accessible later. Set up a “safety code word” that students may use at any time to stop the role play and take a break.

Command of details:  Students who are more deeply involved may have many more detailed and persistent questions which will require that you have a lot of additional detail about the situation and characters. They may also question the value of role plays as a teaching method, so be prepared with pithy explanations.

Can you help?  Students may be concerned about how their acting will affect their grade, and want assistance in determining how to play their assigned character and need time to get into their role. Tell them they will not be marked on their acting. Say there is no single correct way to play a character. Prepare for slow starts, gaps in the action, and awkward moments. If someone really doesn’t want to take a role, let them participate by other means—as a recorder, moderator, technical support, observer, props…

Considered reflection:  Reflection and discussion are the main ways of learning from role plays. Players should reflect on what they felt, perceived, and learned from the session. Review the key events of the role play and consider what people would do differently and why. Include reflections of observers. Facilitate the discussion, but don’t impose your opinions, and play a neutral, background role. Be prepared to start with some of your own feedback if discussion is slow to start.

An engineering role play adaptation

Boundary objects (e.g., storyboards) have been used in engineering and computer science design projects to facilitate collaboration between specialists from different disciplines (Diaz, 6-80). In one instance, role play was used in a collaborative design workshop as a way of making computer scientist or engineering students play project roles they are not accustomed to thinking about, such as project manager, designer, user design specialist, etc. (Diaz 6-81).

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.

Create a Case Method Group Activity to Engage Students in Critical Thinking

The case method group activity is an instructional design strategy that involves faculty members providing one or more case studies to which groups of students respond. The case(s) could be a real-life case or simulation. It could be description of key concept(s) applied, a story or scenario, an actual case study, a problem or mystery, a performance, a visual, or an example.

The case method in online learning as an intervention presents students with ill-structured, real-world derived problems with multiple solutions (Choi & Lee, 2009). In a group activity this case method has the potential to harnesses the effectiveness of collaborative learning (Kolb, 1984) and group activities provide a space for collaborative problem solving, fostering a constructivist learning environment with potential to build a community of learning (Jonassen, 1997). The teaching facilitator can influence learners’ engagement in and adoption of the activity by communicating the relative advantage of key features of the online environment (Karamanos & Gibbs, 2012), as well as mapping and intervening in the group interactions to keep students focused on the problem (Etmer & Koehler, 2014). This mapping creates a plan for instructors to scaffold (or build in techniques to progressively support students to greater levels of learning independence and effective group interactions). Introduction of scaffolds and learning resources, perhaps additional readings and activities, presented at later stages of problem solving were associated with deep meaningful learning and critical thinking (Choi & Lee, 2009).

Because the case reflects a real-life situation, as the group members interact with each other, they should uncover multiple solutions, perspectives, or methods of analyzing the situation, with no single right answer. This divergence is important to encourage for fostering deeper levels of learning and critical thinking (Choi & Lee, 2009). A guiding question for the lesson can offer some parameters for faculty to map and scaffold activities, guiding students’ interactions as they engage with others in their groups about the case. This guiding question should depend on the purpose of the instruction (University of Illinois, 2015). The process of a faculty member scaffolding activities should result in more than one individual or group deliverable associated with it and a corresponding timeline for each. Consider, too, whether each component will have a group or individual grade (Carnegie Mellon University, 2015).

Link to example artifact(s)

As an example of the case method group activity, a faculty member teaching an industrial/organizational psychology course divided the students into groups based on time zones and created a discussion forum for each group. They completed a learning team charter to establish their group covenant. The parameters for the group activity were well-defined: students completed a group charter to agree on expectations for each member’s contribution to the group, the faculty provided an explanation of the purpose of the group activity for learning the material and succeeding in the course. The faculty explicitly stated how the quality of interactions and ideas derived from the group conversation and supported with evidence could contribute to the success of individual assignments.

The faculty provided the same case scenario across each group discussion forum. The case described in writing a company whose strict hierarchy and “us” (management) versus “them” (workers) mentality had led to a dysfunctional workplace environment with punitive acts from management and passive aggressive behaviors from employees. The faculty prompted students to analyze the situation using management and leadership approaches and theories from the course as a group by midway through the course, brainstorm as a group solutions to remedy the situation by applying key course concepts from middle to the end of the course, and submit an individual solution to the problem the case presented as the final assignment.

The faculty member interacted with each group several times throughout the course in their discussion forums, guiding them to consider important motivational and management theories (like Maslow’s hierarchy of needs and McGregor’s theory x and y) to analyze the behavioral dynamics of management and the employees in the case. Additionally, a rubric was associated with each component presented prior to the assignment to set expectations and utilized by the faculty member for grading. To assess critical thinking, elements from the AASU Value rubric were incorporated into the individual solution activity rubric (2017). Students were graded individually even though they were interacting as a group for their mid-course analysis of the scenario, as a group on the solution brainstorming activity for a group grade, and individually on their submissions of their individual solution to the case.

Students’ critical thinking improvements and favorable reaction provided good evidence for the success of the case scenario activities in this course. During the discussion, students often related the scenario to their own real-life experiences in workplace settings. As the discussions progressed, students began identifying these experiences with key concepts, referring and citing course content, and this habit transferred to their individual solutions to the case presented in their papers. Some students developed a clear thesis for their perspectives, recounting nuances of the situation in the scenario (such as the organizational structure and emerging management styles) to substantiate their position. Even fewer students gave multiple solutions and explained why one is better than another. Students generally responded positively to the course and case scenario format. They indicated that they appreciated the real-life examples from other students and expressed that the group discussion contributed development of their individual submissions. Satisfaction with the course, as indicated on students’ end-of-course reviews, was high to very high.

Applying this case method group activity strategy to other disciplines should result in similar success, strengthening students’ critical thinking skills. This strategy is definitely generalizable, as the aim is for students’ collaboration for achieving the course or module objective(s) associated with the activity/assignment (University of Illinois, 2015), guiding students to:

• Identify key concepts reflected by a case, • Situate a case within a given system, • Summarize or recapitulate a case, • Generalize patterns or symbolic representations within a case, • Generate plausible causes that result in a case, • Analyze the components of a case, • Assess or judge the appropriate application presented in a case scenario, • Solve a problem that the case presents or that the faculty presents about the case Any discipline where students would benefit cognitively from collaboration to achieve one of the above objectives could apply this strategy: create a case method group activity to engage students in critical thinking.

Students were asked to discuss case studies relating to their subject, and Edmodo was used as a learning platform for handling them. The purpose of integrating the technological tool was to encourage students to actively participate in the teaching and learning process even beyond their classroom. Besides this, Edmodo, as an application could be accessed both in a computer and a mobile, which in turn helps teachers to post resources, initiate discussions, create small groups, and enroll students to do collaborative tasks.

As part of the classroom based research, the students were put in small groups, and inputs for case study was posted as video files and reading texts to each group in the Edmodo page. Each group was given guidance on holding case study discussions. The preliminary discussion was initiated through brainstorming questions, which encouraged students to get to the important issue or aspect of the case study. For example, the following questions were posted related to the case study on ‘ Regenerative medicine- Current therapies and future directions’:

• What do you know about regenerative medicine?
• How does it help common man?

Similarly, one of the groups discussed ‘Genetic Engineering of Animals: ethical issues, including welfare concerns’ and the following questions were asked:

• Discuss how ‘deletion of genes, or the manipulation of genes already present’ affects the animals.
• What do you think about this as a biotechnology student?

After a few dialogues online, it was felt that most of the students could not identify the main aspect of the case study and the teacher researcher had to intervene by posting guidelines for discussing a case study (Source: https://plato.acadiau.ca/courses/Busi/IntroBus/CASEMETHOD.html#CASEMETHOD ). They were told about the process by which a case study has to be analysed. They were asked to look for issues that are stated in the case study, critically read and see how the issue is handled in depth. Then, they had to look for opening paragraph, background information, specific area of interest covered, specific problem stated, alternatives given and the conclusion drawn from the discussion, in the case study.

Besides posting these tips for handling case studies, the teacher explained the components of a case study (stated above) in the class. It was felt that this online collaborative activity had to be handled by following the online collaborative theory advocated by Harasim (2012). According to her, a teacher plays an important role (in an online collaborative learning scenario) in the process of knowledge construction among students, by providing inputs and integrating the core concept along with the subject domain. In this context, it must be stated that the teacher researcher had already brought in the integration of biotechnology related case studies for discussion. However, considering the extent to which they could use the subject knowledge for discussing the given case study, it was evident that the students expected teacher’s intervention. In other words, the teacher had to draw their attention to the main issue of the case study by posting a few specific (case study related) questions.

For example, the group which was working on the case study, ‘Genetic engineering of animals’, were asked to focus on the specific concepts. The following question was posted in Edmodo group page:

• How does it affect an animal when it is genetically modified or genetically altered or genetically manipulated or transgenic, and biotechnology-derived
• How will the animal cope with when it is modified?

The extent to which the students of respective groups (group A & B) could discuss the case study by using their subject knowledge was evaluated by comparing two groups (both before-the-intervention and after-the-intervention of the teacher) using Causal-Comparative method. The analysis of performance of the group members was done with the help of the rubrics, ‘Undergraduate Case Analysis Rubrics’ (Source https://www.onlineethics.org/File.aspx?id=31203&v=859a7ffb ). The frequency polygon drawn for both groups (Figures 1 and 2) and the ANOVA test scores evaluated showed variation, particularly in group A’s performance (ie before and after teacher’s intervention).

It was evident that students’ application of subject knowledge in their discussion had promoted communicative ability. Further, it proved the application of online collaborative theory in encouraging students to contribute to online discussions.

Making Learning Relevant With Case Studies

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

Your content has been saved!

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:

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.

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

What is case-based learning.

Using a case-based approach engages students in discussion of specific scenarios that resemble or typically are real-world examples. This method is learner-centered with intense interaction between participants as they build their knowledge and work together as a group to examine the case. The instructor's role is that of a facilitator while the students collaboratively analyze and address problems and resolve questions that have no single right answer.

Clyde Freeman Herreid provides eleven basic rules for case-based learning.

• Tells a story.
• Focuses on an interest-arousing issue.
• Set in the past five years
• Creates empathy with the central characters.
• Includes quotations. There is no better way to understand a situation and to gain empathy for the characters
• Relevant to the reader.
• Must have pedagogic utility.
• Conflict provoking.
• Decision forcing.
• Has generality.

Why Use Case-Based Learning?

To provide students with a relevant opportunity to see theory in practice. Real world or authentic contexts expose students to viewpoints from multiple sources and see why people may want different outcomes. Students can also see how a decision will impact different participants, both positively and negatively.

To require students to analyze data in order to reach a conclusion. Since many assignments are open-ended, students can practice choosing appropriate analytic techniques as well. Instructors who use case-based learning say that their students are more engaged, interested, and involved in the class.

To develop analytic, communicative and collaborative skills along with content knowledge. In their effort to find solutions and reach decisions through discussion, students sort out factual data, apply analytic tools, articulate issues, reflect on their relevant experiences, and draw conclusions they can relate to new situations. In the process, they acquire substantive knowledge and develop analytic, collaborative, and communication skills.

Many faculty also use case studies in their curriculum to teach content, connect students with real life data, or provide opportunities for students to put themselves in the decision maker's shoes.

Teaching Strategies for Case-Based Learning

By bringing real world problems into student learning, cases invite active participation and innovative solutions to problems as they work together to reach a judgment, decision, recommendation, prediction or other concrete outcome.

The Campus Instructional Consulting unit at Indiana University has created a great resource for case-based learning. The following is from their website which we have permission to use.

Formats for Cases

• “Finished” cases based on facts: for analysis only, since the solution is indicated or alternate solutions are suggested.
• “Unfinished” open-ended cases: the results are not yet clear (either because the case has not come to a factual conclusion in real life, or because the instructor has eliminated the final facts.) Students must predict, make choices and offer suggestions that will affect the outcome.
• Fictional cases: entirely written by the instructor—can be open-ended or finished. Cautionary note: the case must be both complex enough to mimic reality, yet not have so many “red herrings” as to obscure the goal of the exercise.
• Original documents: news articles, reports with data and statistics, summaries, excerpts from historical writings, artifacts, literary passages, video and audio recordings, ethnographies, etc. With the right questions, these can become problem-solving opportunities. Comparison between two original documents related to the same topic or theme is a strong strategy for encouraging both analysis and synthesis. This gives the opportunity for presenting more than one side of an argument, making the conflicts more complex.

Managing a Case Assignment

• Design discussions for small groups. 3-6 students are an ideal group size for setting up a discussion on a case.
• Design the narrative or situation such that it requires participants to reach a judgment, decision, recommendation, prediction or other concrete outcome. If possible, require each group to reach a consensus on the decision requested.
• Structure the discussion. The instructor should provide a series of written questions to guide small group discussion. Pay careful attention to the sequencing of the questions. Early questions might ask participants to make observations about the facts of the case. Later questions could ask for comparisons, contrasts, and analyses of competing observations or hypotheses. Final questions might ask students to take a position on the matter. The purpose of these questions is to stimulate, guide or prod (but not dictate) participants’ observations and analyses. The questions should be impossible to answer with a simple yes or no.
• Debrief the discussion to compare group responses. Help the whole class interprets and understand the implications of their solutions.
• Allow groups to work without instructor interference. The instructor must be comfortable with ambiguity and with adopting the non-traditional roles of witness and resource, rather than authority.

Designing Case Study Questions

Cases can be more or less “directed” by the kinds of questions asked. These kinds of questions can be appended to any case, or could be a handout for participants unfamiliar with case studies on how to approach one.

• What is the situation—what do you actually know about it from reading the case? (Distinguishes between fact and assumptions under critical understanding)
• What issues are at stake? (Opportunity for linking to theoretical readings)
• What questions do you have—what information do you still need? Where/how could you find it?
• What problem(s) need to be solved? (Opportunity to discuss communication versus conflict, gaps between assumptions, sides of the argument)
• What are all the possible options? What are the pros/cons of each option?
• What are the underlying assumptions for [person X] in the case—where do you see them?
• What criteria should you use when choosing an option? What does that mean about your assumptions?

Managing Discussion and Debate Effectively

• Delay the problem-solving part until the rest of the discussion has had time to develop. Start with expository questions to clarify the facts, then move to analysis, and finally to evaluation, judgment, and recommendations.
• Shift points of view: “Now that we’ve seen it from [W’s] standpoint, what’s happening here from [Y’s] standpoint?” What evidence would support Y’s position? What are the dynamics between the two positions?
• Shift levels of abstraction: if the answer to the question above is “It’s just a bad situation for her,” quotations help: When [Y] says “_____,” what are her assumptions? Or seek more concrete explanations: Why does she hold this point of view?”
• Ask for benefits/disadvantages of a position; for all sides.
• Shift time frame— not just to “What’s next?” but also to “How could this situation have been different?” What could have been done earlier to head off this conflict and turn it into a productive conversation? Is it too late to fix this? What are possible leverage points for a more productive discussion? What good can come of the existing situation?
• Shift to another context: We see how a person who thinks X would see the situation. How would a person who thinks Y see it? We see what happened in the Johannesburg news, how could this be handled in [your town/province]? How might [insert person, organization] address this problem?
• Follow-up questions: “What do you mean by ___?” Or, “Could you clarify what you said about ___?” (even if it was a pretty clear statement—this gives students time for thinking, developing different views, and exploration in more depth). Or “How would you square that observation with what [name of person] pointed out?”
• Point out and acknowledge differences in discussion— “that’s an interesting difference from what Sam just said, Sarah. Let’s look at where the differences lie.” (let sides clarify their points before moving on).
