spaced repetition
Spaced repetition is a learning technique in which material is reviewed at gradually increasing intervals to improve long-term retention.
Spaced repetition is a learning technique built on the spacing effect, the finding that people remember material longer when reviews are spread out over time rather than crammed together. Items recalled easily are scheduled for review after longer intervals, while forgotten items come back sooner.
Well-known approaches include the Leitner system, which sorts flashcards into boxes, and scheduling algorithms such as SM-2. Flashcard apps such as Anki and many other study tools use the method.
