Retrieval Practice
Test yourself — don’t just re-read.
What the Research Says
Retrieval practice is the act of pulling information out of your memory, rather than pushing it in. It sounds simple but it is the most powerful revision technique we have — stronger than highlighting, stronger than re-reading, stronger than watching videos. The harder the retrieval feels, the more your long-term memory is strengthening.
Evidence Base
| Study | Finding | Impact |
|---|---|---|
| Roediger & Karpicke (2006) | Students who self-tested once remembered 50% more a week later than those who re-read four times. | Self-testing > re-reading, even when it feels harder. |
| Karpicke & Blunt (2011) | Retrieval practice beat concept-mapping and elaborative study on a delayed test by ~50%. | Works better than other “active” strategies that feel productive. |
| Agarwal et al. (2017) | Low-stakes retrieval quizzes raised test scores by an average of one grade. | Short regular quizzing moves your real exam score. |
| Smith et al. (2016) | Students who practised retrieval scored higher even on questions testing information they didn’t specifically retrieve. | Builds the skill of remembering itself, not just the facts. |
Step-by-Step Method
- 1Study a chunk of content — read through a lesson, watch a video, or cover a topic in class. Don’t try to memorise. Just understand.
- 2Close everything — book shut, tab closed, notes flipped over. The whole point is that you cannot see the material.
- 3Write down everything you can remember — no looking back. This is called a “brain dump.” Write until you run out. It should feel uncomfortable.
- 4Check against the source — open the lesson. Mark what you missed in a different colour. Don’t just glance — properly compare.
- 5Target the gaps — re-study only the parts you missed. Not the whole lesson again. Just the holes.
- 6Retest tomorrow — hit the same topic again within 24 hours. The second attempt is where the learning locks in.
After studying the Hundred Years War or the Elizabethan period, close the lesson and write every named event from memory with its precise date: the Statute of Labourers (1351), the Treaty of Brétigny (1360), the Peasants’ Revolt (1381), the Armada (1588), the Poor Law (1601). Next to each, add the named individual most closely associated with it. Examiners award marks only for accurate factual recall, so a date one year out or a misspelled name can cost you. Precision matters far more than volume — ten facts you know cold beat thirty you half-know. Check back and highlight anything you misplaced by more than five years or misidentified the person behind.
Brain-dump specialist vocabulary completely from memory for one option. For Germany 1919–1939: Anschluss, Enabling Act, Kristallnacht, Lebensraum, the Reichstag fire and Night of the Long Knives with their dates and a one-sentence definition for each. For the thematic studies, terms like chevauchée (Hundred Years War tactics), recusancy (Elizabethan religious non-conformity) and perestroika (Soviet reform under Gorbachev) carry marks in both recall questions and the SPaG band of extended responses. Spell them correctly in your dump. Wait three days and retest cold.
Common Pitfalls
- Peeking. If you look back during the brain dump, you’re not doing retrieval — you’re doing copying. Harder is better.
- Only doing it once. One pass strengthens memory a little. Spaced repeats strengthen it permanently. Come back to the same topic 2–3 times over a week.
- Doing it too soon after studying. If you retrieve while the material is still in short-term memory, it’s too easy to count. Leave at least 30 minutes between studying and testing.
- Stopping when it feels difficult. Desirable difficulty is the whole point. If it feels easy, your memory isn’t being challenged and you’re not learning.
When to Use This
Build it in every week, from the start of your course through to your exams. Aim for 15–20 minutes per session, two or three times a week. The last two weeks before an exam is when retrieval practice becomes your main tool — swap passive reading for brain dumps and flashcards. On StudyVault, the Knowledge Check and Flashcard buttons in every lesson sidebar are retrieval practice in disguise — use them.
