Close the notes: a small guide to retrieval practice

A page can feel familiar while your explanation still has gaps. Retrieval practice means trying to produce an answer from memory rather than immediately looking it up. A blank sheet, a spoken explanation, or a short question can all give you a concrete response to check.

What the studies found

In 2006 experiments, prior recall practice outperformed rereading on delayed memory tests. [1]

A 2023 preregistered comparison highlighted the importance of matching study time across methods. [2]

A small experiment

1. Choose a small section you have already studied. Close it and explain the central idea in your own words, using a fresh example.
2. Open the source and compare. Mark one missing point and correct it explicitly; guessing a multiple-choice letter is not the same as explaining your reasoning.
3. Return later and try a different question about the same idea. Keep the explanation and the answer key available for checking, rather than treating a score as the whole lesson.

Limits to keep in mind

Task design, feedback, and study time matter. These findings do not show that every quiz beats every other method, or that DinoLock itself has been validated by these experiments.

Use questions to discover what needs another explanation. Getting something wrong can be a useful prompt to revisit the material, not a judgment about your ability.
