Active Recall: What It Is and How to Use It
Active recall means trying to pull an answer out of your memory before you look at it. By the end of this guide you will have five ways to do it with the notes you already own, a same-day routine to try, and a clear picture of how it differs from rereading.
We keep this article practical. The experiments behind the idea have their own write-up in the testing effect explained. Researchers often call the same idea retrieval practice: bringing information back from memory instead of looking at it again.

Active recall versus rereading
Rereading and highlighting are passive, because the answer sits in front of you the whole time. Active recall hides the answer first, so you have to produce it. A major review of study techniques rated practice testing as high utility, rated rereading and highlighting as low utility, and suggested using practice testing in place of rereading (Dunlosky et al., 2013).
| Question | Rereading your notes | Active recall |
|---|---|---|
| What you do | Read the page again, often with a highlighter. | Close the page and try to produce the answer. |
| How it feels | Smooth and familiar. Familiarity can be mistaken for understanding (Bjork and Bjork, 2011). | Harder, with gaps you can see. Some effort is the point. |
| What it tells you | Little about what you can produce on your own. | Which items you can retrieve and which you cannot. |
| What you do next | Read on. Nothing flags the weak spots. | Mark the misses and ask them again after a short break. |
Another review, this one focused on retrieval research, reports that retrieval practice often produces large gains in long-term retention compared with repeated studying, and that it can help knowledge transfer to different contexts (Roediger and Butler, 2011). The size of the benefit depends on the materials, the delay and the test format. Read it as a direction, not a promise.
Five ways to do active recall with ordinary notes
Each method below turns notes you already have into something you must answer. They are practical applications of the retrieval idea, and the studies we cite did not test each one separately. For more solo options and their time costs, see how to quiz yourself.
- Blank-page recall. Close your notes and write everything you remember about one topic. Then open the notes and add what you missed in a different color.
- Heading questions. Turn each heading in your notes into a question, such as 'What are the stages of this process?', and answer it before you look.
- Cover and recite. Fold the page, or cover one column of a two-column note. Say the hidden side aloud, then uncover it to check.
- Flashcards. Put one question on the front and one short answer on the back. How to write flashcards that work covers card design.
- Explain it aloud. Act as if you are teaching the topic to someone who has not seen your notes. Mark the places where you stall. Those spots are your gaps.
A same-day routine to try today
- I tried to answer before I looked.
- I checked every answer against my notes, including the ones that felt right.
- I marked what I missed.
- I picked a date for the next review, even if it is only a note in my calendar.
The checking step matters. Retrieval practice is often effective even without feedback, but feedback enhances the benefits (Roediger and Butler, 2011). The details are in why you should check every answer.
When recall feels too hard or too easy
Difficulty helps only up to a point. Bjork and Bjork (2011) stress that a difficulty is desirable only when the learner has the background knowledge or skills to respond to it successfully. If you draw a blank on something you barely studied, read the answer, close it, and try again after a short pause.
Prefer producing an answer to recognizing one. A meta-analysis found that initial recall tests produced larger testing benefits than recognition tests, which the author reads as support for effortful processing (Rowland, 2014).
Once an item feels easy, do not stop. Spread the next attempts over days, as described in what spaced repetition is. You can also practice with a starter deck on active recall in Practice.
Common mistakes
- Peeking after a few seconds. Commit to a best guess first, by saying it or writing it. Then you can tell whether you really knew the answer.
- Recalling only what feels easy. Start with the headings you like least, and use the misses from your last session to choose.
- Skipping the check. Compare every answer with your notes. Feedback enhances the benefits of retrieval practice (Roediger and Butler, 2011).
- Using recognition when you need production, such as picking from options. Write or say the answer from scratch. Recall tests gave larger benefits than recognition tests in a meta-analysis (Rowland, 2014).
- Doing one round and stopping. Come back after a day or more and ask the missed questions again. Spreading rounds apart is the idea behind spaced repetition.
Frequently asked questions
Is active recall the same as the testing effect?
They are closely related. Active recall is the study method: you try to retrieve an answer. The testing effect is the research finding that taking a test can improve later memory. The research side is covered in our testing effect article.
How long should an active recall session last?
None of the sources we read for this article sets a length. A block of 10 to 20 minutes on one topic is a reasonable start, and this is our suggestion rather than a finding. Stop when your answers turn sloppy.
Does active recall help with understanding, or only with facts?
A review reports that retrieval practice promotes knowledge that can be flexibly retrieved and transferred to different contexts (Roediger and Butler, 2011). Our suggestion, not a finding: ask why and how questions, not only what questions.
Can I use active recall without flashcards?
Yes. Flashcards are only one of the five methods in this guide, and the other four need nothing but your notes and a pen. Blank-page recall, heading questions, cover and recite, and explaining aloud all work the same way: hide the answer, produce it, then check. Cards suit short facts, while blank-page recall and explaining aloud suit topics with several linked parts. That pairing is practical advice, not a tested comparison.
