THE SHORT ANSWER
Ask yourself to recall the idea without looking, explain why it works, compare it with a nearby concept, produce an example and counterexample, identify where it fails, and apply it to a new case. Check the answer against reliable material afterward.
Ask questions that perform different learning jobs
| Move | Prompt |
|---|---|
| Retrieve | What can I recall without reopening the material? |
| Explain | Why does this work in my own words? |
| Compare | How is this different from the nearest idea? |
| Example | What case demonstrates it? |
| Counterexample | Where would this idea fail? |
| Apply | How would I use it in a new situation? |
Use retrieval to expose what is available
Roediger and Karpicke found that free-recall testing improved delayed retention more than repeated study for prose passages in two experiments. That result supports retrieval practice in similar conditions; it does not make every test well designed or every subject reducible to recall.
Close the source, write what you remember, then check and correct it. The correction matters because confident retrieval can still be wrong.

Turn familiarity into explanation
Research on self-explanation and the National Academies synthesis suggests value in asking why, how and what-if questions. The effect depends on prior knowledge, prompts and domain; beginners may need a worked example or feedback before they can explain well.
Ask: ‘Can I explain the link between these two steps?’ and ‘Which part can I repeat but not yet justify?’

Build a five-minute question set
- One recall question
- One why/how question
- One comparison
- One example or counterexample
- One application question
Answer before looking. Mark what you could not explain, revisit only that part, and try again later. Use Turn Curiosity into a Learning Project when the question deserves a longer investigation.
