Retrieval practice: what it is and 15 classroom activities to try
The research behind retrieval practice in plain English, the principles that make it work, and fifteen activities you can use in any lesson.
Pupils often feel they know something because it looks familiar when they read it again. But recognising information is not the same as being able to recall it. Retrieval practice closes that gap: instead of rereading, pupils pull information out of their memory, and that effort makes it stick.
This guide explains the idea in plain English and gives fifteen activities you can use in any subject.
What is retrieval practice?
Retrieval practice is any activity where pupils bring knowledge back to mind without looking it up. Answering quiz questions, writing down everything they remember, or explaining an idea from memory all count.
Researchers call the benefit the testing effect. In a well-known study, Henry Roediger and Jeffrey Karpicke found that students who practised recalling a text remembered more of it a week later than students who spent the same time rereading it, even though the rereaders felt more confident. The Association for Psychological Science has a readable introduction to test-enhanced learning, and RetrievalPractice.org collects research and guides for teachers.
Four principles that make it work
Keep the stakes low
Retrieval practice is for learning, not grading. No marks in the gradebook, no ranking, no pressure. Pupils should feel safe getting answers wrong, because the mistakes show what to revisit.
Space it out
Recalling something the day after you learned it is good. Recalling it again a week later, and again a month later, is better. Mix old topics into your quizzes, not just last lesson's. Rosenshine's Principles of Instruction include weekly and monthly review for exactly this reason.
Give feedback
Always go through the answers. Pupils need to know which of their memories were right, and wrong answers need correcting before they stick.
Make it effortful but achievable
If questions are too easy, there is little benefit. If they're far too hard, pupils give up. Aim for questions most of the class can answer with some effort.
15 retrieval practice activities
Quick quizzes
- Five-a-day. Five short questions at the start of every lesson: two from last lesson, two from last month, one from last term.
- Mini whiteboard round. Ask a question, everyone writes, everyone shows. Repeat for five questions.
- Multiple-choice with "why". Pupils choose an answer, then write one sentence explaining why the others are wrong.
- Quiz, quiz, trade. Each pupil has a question card. Pairs quiz each other, swap cards and find a new partner.
- Retrieval grid. A grid of questions worth one, two or three points depending on how long ago the topic was taught. Pupils aim for a target score.
Free recall
- Brain dump. Two minutes to write everything you remember about a topic. Then check notes and add missing points in a different colour.
- Concept map from memory. Draw a map linking the key ideas from a topic, without notes.
- Draw and label. Draw a diagram from memory, such as the heart, a river or a plant cell, and label as much as you can.
- Timeline from memory. Put five events in order and add one detail to each.
Talk-based retrieval
- Think, pair, share. Each pupil recalls on their own first, then compares with a partner.
- Just a minute. Speak for one minute on a topic without notes; partners note anything missed.
- Teach it back. Explain yesterday's lesson to a partner as if they had missed it.
Games with a purpose
- Retrieval bingo. Pupils fill a bingo grid with key words; you read definitions and they mark the matching word.
- Last one standing. Everyone stands; take turns naming a fact about a topic. Repeat a fact or hesitate and you sit down.
- Flashcard sort. Pupils test themselves with flashcards, putting cards they knew in one pile and cards to repeat in another.
How to fit it into your lessons
- Use a retrieval quiz as your starter most lessons. Our lesson starter ideas include several more formats.
- Keep a list of key questions for each unit, so you can mix older topics into quizzes quickly.
- Teach pupils why you do it. When they understand that recalling helps memory, they're more likely to use it in their own revision.
- Use the results formatively: if the class has forgotten something, plan a short recap. See formative assessment strategies for more.
Common mistakes
- Only asking about last lesson. Spacing is where much of the benefit comes from.
- Grading every quiz. It raises anxiety and turns practice into performance.
- Skipping feedback. Without it, pupils may remember their wrong answers.
- Questions that only need recognition. Mix in questions that ask pupils to explain, not just pick.
Lesson Dino's slides can include quiz, true or false and fill-the-gap slides, and its worksheets include an answer sheet, so you can turn any lesson into retrieval practice for a later one.
Questions teachers ask
What is retrieval practice?
Retrieval practice means bringing information back to mind from memory, for example by answering questions without looking at notes. The act of recalling strengthens memory, so it is a way to learn, not only a way to check learning.
Is retrieval practice the same as testing?
It often uses quiz-style questions, but it works best when the stakes are low: no grades, no pressure, quick feedback. The purpose is to help pupils remember, not to rank them.
How often should pupils do retrieval practice?
Little and often. A few minutes in most lessons, spread out over days and weeks, works better than one long revision session before a test.
Does retrieval practice work for young children?
Yes, with simple formats such as picture quizzes, 'show me' cards and talking with a partner. Keep it playful and quick.
