Active recall means trying to pull an answer out of your own memory before you look it up, then checking how you did. For a Year 7 to 9 pupil it is one of the most useful changes to make to revision, and it needs nothing more than paper and a few minutes.
The idea is simple enough to state in one line, and easy to get wrong in practice. Reading your notes is putting information in. Recalling is getting it out. Exams mostly ask for the second, so practising the second is the most direct preparation there is.
Why it works
A big review of ten study techniques (Dunlosky and colleagues, 2013) named practice testing as one of the two most useful, because it helps pupils of different ages and abilities across many kinds of task. Two explanations are commonly given. First, the effort of retrieving strengthens the memory more than another look at the answer. Second, it tells you truthfully what you do not know. Rereading cannot do that, because a familiar page always looks familiar.
The EEF's guidance on metacognition makes a related point: it gives self-testing with flashcards as an example of an effective revision strategy, and stresses that effective learners monitor their own progress, for instance by answering past questions. That fits the idea that the check matters as much as the attempt.

- 2CheckLook, and mark what was missing
- 3FixWork on the gaps, then retest
Six ways to do it at home
All of these follow the same three beats: attempt, check, fix.
- Blank-page recall. Shut the book. Write everything you remember about a topic. Open the book and mark in another colour what was missing. Ten minutes, no equipment.
- Question cards. Put a question on the front and the answer on the back. For example, front: "Why does ice float?"; back: "Water expands as it freezes, so ice is less dense than liquid water." Flashcards are just active recall you can carry around; how to make flashcards that work covers writing them well.
- Teach a parent. The pupil explains the topic from memory to someone who does not know it. The parent's only job is to ask "why?" and "what would happen if...?"
- Practice questions, book shut. Do past-style questions with no notes open. Mark them after, and keep a list of what cost marks.
- Cover and test. Fold a page so one column is hidden, say a list of French verbs or key dates, and recall the hidden side.
- Explain a diagram. Draw the water cycle, a cell, or a map from scratch, then compare it with the textbook version.
- Blank-page recallWrite it all, then check
- Question cardsQuestion front, answer back
- Teach a parentParent asks why
- Practice questionsBook shut, then mark
- Cover and testHide one column
- Explain a diagramDraw it from scratch
A worked example
Take a Year 8 pupil revising the topic "photosynthesis" for science.
Attempt. Book shut, they write: "Plants use sunlight to make glucose. Needs carbon dioxide and water. Gives out oxygen." They get stuck on where it happens.
Check. They open the notes. Nothing wrong so far; the missing piece is "in the chloroplasts, using chlorophyll to absorb light". They mark that in green pen.
Fix. They say the full word equation aloud once with the gap filled in, then draw a small leaf-cell sketch with chloroplasts labelled.
Retest. Two days later: a blank page again. If "chloroplasts" comes back without help, it has started to stick. If not, the gap goes at the top of the next list.
The whole cycle took about fifteen minutes and covered only what was actually unknown.
What to watch for
- Peeking too soon. If the pupil glances at the answer after two seconds, it is reading, not recalling. Give it a real go, even a slow one.
- Only doing the easy cards. Easy success feels nice and teaches little. Put the ones you got wrong first.
- Skipping the check. A wrong answer you never correct can be remembered as right. Always look.
- Turning it into an interrogation. Keep the tone light. A tense quiz makes a 12-year-old avoid the practice.
If the same thing keeps going wrong, the trouble is usually not memory but understanding. Go back and get it explained, then return to recall.
Active recall in Heddy
In Heddy, the review room follows this pattern: you see the front of a card, try to answer in your head, then flip and tap Again, Good or Easy, honestly. Heddy's tutors can also turn the lesson you just had into cards, so the raw material comes from your own gaps. But everything above works on paper, which is a fine place to start. For how often to bring each topic back, see spaced repetition explained for parents, and for a full routine, how to revise for KS3 exams.

Questions people ask
What is active recall?
Active recall means producing an answer from memory before checking it, instead of rereading it. Closing the book and writing down what you remember is active recall; reading the page again is not.
Is active recall the same as retrieval practice?
Yes, for practical purposes. Retrieval practice is the name researchers use; active recall is the name students use. Practice testing is a third label for the same thing.
Does it matter if my child gets answers wrong?
No, provided they check and correct. A wrong attempt followed by the right answer is a normal, useful part of the method. The problem is skipping the check, not getting things wrong.
How is active recall different from just being quizzed?
It is not different in kind. A quiz is one way to do it. The key ingredients are that the answer comes from memory first, and that the pupil gets feedback afterwards.
