Retrieval practice that takes five minutes
Retrieval practice is one of the most reliable findings in learning science — and one of the cheapest to run. Here is how to fit it into a normal lesson.
Amelia FordAug 18, 20261 min readRetrieval practice — the act of bringing information to mind rather than re-reading it — is one of the most reliable findings in cognitive science. It also happens to be free, quick, and easy to build into a lesson you have already planned.
Why it works
Every time a student successfully recalls something, the memory for it gets stronger and more durable. Re-reading feels productive but mostly builds familiarity, not recall. The struggle to remember is the point.
Three routines you can start tomorrow
- Last lesson, last week, last term. Open with three quick questions — one from the previous lesson, one from the previous week, one from earlier in the year.
- Brain dump. Give students two minutes to write everything they remember about a topic, then compare with a partner.
- Mini whiteboards. Ask a question, everyone answers, everyone shows. You see the whole class at once.
The goal is not to grade these. The goal is for every student to try to remember, and for you to see what has stuck.
Keep it low-stakes
Retrieval only helps if students actually attempt it, and they will only attempt it if getting something wrong is safe. Mark nothing. Celebrate partial answers. Move on.
