How do I Promote Clinical Reasoning in the Classroom?
Clinical reasoning develops when students have repeated opportunities to use what they know to interpret information, make connections, consider alternatives, and make decisions. This does not require elaborate simulations, lengthy cases, or major changes to a course. Small changes to a lecture or classroom discussion can shift students from primarily receiving information to practicing how that information is used in clinical thinking. The following are simple ways to infuse clinical reasoning into your teaching practice:
Move Beyond “What?” to “So What?”
Many classroom questions ask students to recall information:
- What are the signs of bacterial keratitis?
Recall is important, particularly when students are developing foundational knowledge. However, clinical reasoning requires students to determine what information means and what to do with it. After asking a knowledge question, add a reasoning question:
- Which of these findings would concern you most? Why?
- How would this finding change your differential diagnosis?
- What would you want to know next?
- How might this affect your management?
A simple follow-up question can turn retrieval of knowledge into an opportunity to practice using that knowledge.
Ask Students to Predict Before Giving the Answer
Before revealing a diagnosis, test result, consequence, or next step, ask students to predict it.
For example:
- Based on what we know so far, what would you expect to find on examination?
- If this mechanism is responsible, what should happen next?
- Which test result would you expect?
- What would you expect to change after treatment?
Prediction requires students to activate their existing knowledge, construct an explanation, and apply it to the situation. Importantly, students do not always need to submit an answer. Even briefly asking them to commit mentally to a prediction before revealing the answer changes the cognitive task.
Ask “Why?”
One of the simplest ways to promote reasoning is to require students to justify an answer. Instead of stopping after identifying the correct diagnosis, treatment, test, or finding, ask, “Why?”
Or, more specifically:
- What information led you to that conclusion?
- Which finding provides the strongest support?
- What mechanism explains this finding?
- Why would you choose this treatment rather than the alternative?
- What makes the other option less likely?
The goal is to make the reasoning behind the answer visible. A correct answer does not necessarily indicate correct reasoning, and an incorrect answer may reveal reasoning that is partially sound but based on a particular misconception.
Reveal Cases Gradually
Clinical encounters rarely begin with all relevant information neatly organized and presented simultaneously. Faculty can approximate this uncertainty without developing elaborate cases by revealing information in stages.
For example, start with the presenting complaint
- A 62-year-old patient presents with sudden painless vision loss in one eye. What possibilities are you considering?
Add history
- The patient reports noticing the vision loss immediately upon waking. Does this change your thinking?
Add examination findings
- Visual acuity is 20/200 and a relative afferent pupillary defect is present. What moves higher or lower on your differential?
Add another finding
- Fundus examination reveals optic disc edema with peripapillary hemorrhages. What is your leading diagnosis now?
Pause briefly after each piece of information. This allows students to practice updating their thinking as new evidence becomes available, an important component of clinical reasoning.
Ask “What Would Change Your Mind?”
Once students have selected a diagnosis or course of action, introduce uncertainty:
- What additional finding would make you reconsider?
- What information would make this diagnosis less likely?
- What finding would cause you to change the treatment plan?
- What alternative diagnosis are you most concerned about excluding?
These questions encourage students to avoid becoming overly attached to their initial conclusion and reinforce the idea that clinical decisions should remain responsive to new evidence.
Compare Similar Conditions
Clinical reasoning frequently requires distinguishing among conditions that share similar characteristics. Rather than teaching related conditions entirely in isolation, periodically ask students to compare them.
For example:
- Both conditions can cause a red eye. What finding would help you distinguish between them?
- Which feature is most useful in differentiating these diagnoses?
- What finding would be unusual for Condition A but expected in Condition B?
A simple comparison table can also become a reasoning activity. Instead of providing a completed table, provide some information and ask students to identify the features that are most diagnostically useful. This helps students move beyond memorizing lists of findings toward recognizing patterns and discriminating among competing possibilities.
Ask for a Differential, Not Just a Diagnosis
When presenting a case, resist immediately asking, “What is the diagnosis?”
Instead, ask: “What are the two or three diagnoses you are considering?”
Then follow with:
- What evidence supports each possibility?
- What evidence argues against each?
- What information would help you distinguish among them?
This shifts the task from recognizing the instructor’s intended answer to evaluating competing explanations. Even a 60-second discussion can provide meaningful practice with differential diagnosis.
Think Aloud
Students often see an instructor’s final conclusion without seeing the reasoning that produced it. Periodically make your own reasoning explicit:
“The patient’s age and symptoms initially make me consider X. However, this particular finding doesn’t fit very well. That makes me more concerned about Y. Before committing to that diagnosis, I would want to know…”
This allows students to observe how an experienced clinician:
- Identifies important information
- Connects findings to prior knowledge
- Generates possible explanations
- Weighs competing evidence
- Recognizes uncertainty
- Determines what information is needed next
Expert reasoning is often highly automated. Thinking aloud makes otherwise invisible cognitive processes available to novice learners.
Ask Students to Identify What Matters
Novices often struggle to distinguish clinically meaningful information from background detail. After presenting a case, image, history, or set of findings, ask:
- Which three pieces of information are most important?
- Which finding should receive the greatest attention?
Then ask students to explain their choices. This provides practice with prioritizing and organizing information, rather than treating every fact as equally important.
Use “One-Minute Cases”
Cases do not need to consume an entire class period. A short case can be inserted into a lecture in only a few minutes:
- Patient: 24-year-old with unilateral red eye and photophobia
- History: Contact lens wearer; slept in lenses last night
- Finding: Small central corneal infiltrate
Then ask one question:
- What should the clinician be most concerned about, and what information supports that concern?
The class can think individually, discuss with a neighbor, respond to a poll, or simply consider the question before the instructor explains the reasoning. Several short reasoning opportunities distributed throughout a lecture may be more practical than a single elaborate case.
Use Polling as a Reasoning Tool
Polling questions do not have to function only as knowledge checks. Present a brief scenario and ask students to choose a diagnosis, next step, additional test, or management decision. Before revealing the correct answer, ask students to discuss why they selected their response.
An especially useful sequence is:
- Students answer individually.
- Students briefly discuss their reasoning with a neighbor.
- Students answer again.
- The instructor discusses the reasoning behind the options.
The discussion is often more educationally valuable than the poll itself.
Occasionally Remove Information
Students are frequently given complete cases in which every piece of information needed to answer the question is already available. Clinical practice rarely works this way.
Instead of asking students only to interpret information you provide, ask:
- What else would you want to know?
- What examination would you perform next?
- What test would help you distinguish between these possibilities?
- What information is missing before you can make this decision?
Determining what information is needed is itself an important component of clinical reasoning.
Make Small Changes Frequently
Developing clinical reasoning does not require abandoning lectures or redesigning every class around complex cases. A useful goal is simply to create frequent moments in which students must do something with their knowledge.
During an otherwise traditional lecture, periodically ask students to:
- Predict what will happen next
- Explain why something occurs
- Identify the most important finding
- Compare two possibilities
- Generate a short differential
- Decide what information is needed next
- Select a course of action and justify it
- Identify what would change their decision
Even a few minutes of reasoning practice can interrupt passive information delivery and require students to retrieve, organize, and apply what they are learning.
Start with One Simple Change
You do not need to use every strategy on this page. For your next lecture, identify one or two places where students would normally receive an answer from you. Pause before providing it and ask them to predict, decide, or explain first.
A useful rule of thumb: Before telling students what an expert would conclude, give them an opportunity to think about what they would conclude and why.
Repeated across courses and throughout the curriculum, these small opportunities help students practice connecting foundational knowledge to the reasoning they will eventually be expected to perform independently in clinical settings.
