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 seven entrepreneur characteristics, close the lesson and write them all from memory: creativity, innovation, risk-taking, communication, negotiation, confidence, determination. For each one, write one sentence showing it in action for a fictional start-up — for example, “Priya at Hatcher’s Hot Sauce showed determination by continuing after her first retailer turned her down.” Check back and highlight any characteristic you missed or described vaguely — those become your focus for the next day’s review.
Brain-dump every fixed cost you can recall (rent, salaries, utilities, insurance, advertising) and every variable cost (raw materials, packaging, wages). This is a high-frequency misconception area: for this qualification, salaries are fixed and wages are variable — the opposite of what many students assume. After the dump, write a two-column table from memory, check it against the lesson, then write a corrected version of any row you got wrong. Do this again in three days 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.
