Description¶

Case based discussion places learners in front of a rich, authentic case — a patient history, a business dilemma, a legal dispute, an engineering failure — and asks them to analyze it aloud together, typically in a facilitated small-group or seminar format. The instructor acts as discussion leader rather than lecturer, probing reasoning, surfacing assumptions, and withholding the "answer" until learners have committed to and defended a position. It is the interactive core of Case Studies, distinct from merely reading or being told about a case.

Design Implications¶

Discussion of authentic cases forces learners to apply concepts under the ambiguity of real-world conditions, converting inert knowledge into usable judgment Case-based learning improves exam performance over lecture in health professions education. [+M]. Because a single case is one instantiation of a concept, discussing multiple contrasting cases supports flexible, transferable schema formation Multiple contrasting cases support flexible knowledge transfer. [+M]. The facilitator's role is critical: learning gains depend on learners articulating and defending reasoning, not on the case document itself.

Context¶

Requirements¶

• A well-written, authentic case with genuine ambiguity and multiple defensible positions
• Learners who have prepared — read the case and done preliminary analysis before discussion
• A facilitator skilled in questioning, redirecting, and managing turn-taking without lecturing
• Explicit discussion norms so learners commit to positions and respond to one another, not just the instructor

Constraints¶

• Fails when learners arrive unprepared; discussion collapses into the instructor analyzing the case alone [-M]
• Ineffective for novices lacking the foundational concepts the case requires — they cannot reason about what they do not yet know [~M]
• Large groups suppress participation; without structure, a few voices dominate and most learners passively observe [-M]
• Weak facilitation that rushes to "the right answer" reduces the activity to guess-the-instructor's-thought [-W]

Implementation Variability¶

• Harvard Business School method: cold-calling in a plenary session, with the case as the sole preparation for class
• Small-group jigsaw: subgroups analyze different facets or different cases, then teach one another
• Written pre-analysis: learners submit a position memo before discussion, raising accountability
• Flipped variant: content delivery moves online; class time is devoted entirely to case discussion (Flipped Classroom)

Target Learners¶

• Advanced novices and intermediate learners who have foundational concepts but lack application experience Case-based learning improves exam performance over lecture in health professions education. [+M]
• Professional learners (medicine, law, business, teaching) who must develop judgment under ambiguity
• Not suitable as a first exposure for complete novices, who need direct instruction before case analysis [~M]

Target Learning Goals¶

• Applied problem solving and decision-making in ill-structured domains
• Argumentation: constructing, defending, and revising positions in response to evidence and peers
• Professional reasoning and identity: practicing the habits of mind of a discipline
• Transfer: recognizing when and how concepts apply across varied situations

Instructions¶

1. Select or write an authentic case with genuine ambiguity and stakes; prepare discussion questions that require decisions, not recall.
2. Assign the case in advance with a preparation task (position memo, decision recommendation) to ensure readiness.
3. Open with a brief framing of the decision to be made, then hand analysis to learners — use Class Discussion moves such as probing ("What evidence supports that?") and redirecting ("Does anyone see it differently?").
4. Push learners to Argumentation: require them to commit to a position, defend it, and respond to counterarguments from peers.
5. Facilitate as Coaching — diagnose reasoning errors in the moment and probe rather than correct.
6. Close with an instructor wrap-up that names the concepts the case illustrates, contrasts defensible positions, and connects to other cases or principles — after learners have committed, not before.
7. Follow with a second, contrasting case or a written reflection to consolidate the schema (Anchored Instruction).

Related Strategies¶

• Case Studies — the case material itself; discussion is the processing method applied to it
• Think-Pair-Share — a structure that guarantees individual commitment before whole-group discussion
• Debate — a more adversarial variant when the case has two clearly opposed positions
• Socratic Questioning — the facilitation technique underlying effective probing

• Harvard Business School case method — MBA students analyze a business case daily in plenary discussion led by cold-calling; the model for the case-based learning pattern. https://www.hbs.edu/mba/academic-experience/Pages/the-hbs-case-method.aspx

• Problem-based learning in medical education — tutorial groups discuss patient cases (e.g., the Maastricht and McMaster PBL curricula), with the case triggering self-directed learning followed by re-discussion.
