What is active recall? A simple definition with study examples
Active recall means retrieving an answer from memory before checking it. See why it beats rereading and three ways to use it today.
The definition
Active recall is retrieving information from memory, then checking whether you were right. Answering a flashcard before turning it over, explaining a topic without notes and attempting practice questions are all active recall.
The opposite is passive review: rereading, highlighting or watching a summary. These feel productive because the material looks familiar, but recognising something is easier than producing it on a blank page.
Why it works
In a well-known 2006 study, students who were tested on a passage remembered more a week later than students who spent the same time rereading it. Later research found retrieval practice also beat building concept maps when students were later asked to recall and use the material.
Retrieval strengthens the route back to a memory. It also shows you what you cannot yet recall, which rereading hides.
Three ways to use it today
Flashcards: read the front, say or write your answer, then reveal. Blank page: close your notes, write everything you remember about a topic, then check and fill gaps in a different colour. Practice questions: attempt them before reading the worked solution.
Each method works best when the attempt is genuine. If you reveal too quickly, you are back to recognising the answer.
Add spacing
Active recall works even better when you space it out. Reviewing a card after a day, then a few days, then a few weeks takes less total time than cramming and keeps the memory longer.
A flashcard app with spaced repetition handles that timing. You focus on recalling honestly and grading yourself accurately.
Try it yourself
Which of these is active recall: rereading a chapter, highlighting key terms, or writing the steps of a process from memory and then checking them?

Writing the steps from memory and then checking them.
It requires you to retrieve the information before seeing it. The other two only expose you to it again.
