Spaced repetition is an evidence-based learning technique usually performed with flashcards, in which newly introduced or more difficult flashcards are shown more frequently and older or easier ones less frequently, exploiting the psychological spacing effect; its use has been shown to increase the rate of learning. It is applied especially in contexts where a learner must acquire many items and retain them indefinitely, such as vocabulary acquisition during second-language learning, and can be performed either with spaced repetition software or with physical flashcards using the Leitner system; combined with the testing effect, spaced repetition can further improve long-term memory and ease memorization.
Facts
Core ClaimReviewing information at increasing, spaced intervals produces stronger long-term retention than repeating it in one massed session, exploiting the psychological spacing effect. 1 Origin YearMarks Sebastian Leitner's 1973 Leitner system; the underlying spacing effect was identified earlier, in the 1880s, by Hermann Ebbinghaus. FAQs
Does spaced repetition require the gaps between reviews to keep growing?
No. A uniform review schedule also counts as spaced repetition.
No. Expanding intervals, where the gap grows after each review, are the pattern most commonly associated with spaced repetition, but a uniform schedule, with the same gap between every review, is also a form of spaced repetition procedure.
