Spaced repetition 間隔重複 (间隔重复)

jiàngé chóngfù · from English

What is spaced repetition?

Spaced repetition is reviewing material at increasing intervals, timed just before you would forget it, as done by apps like Anki.

It builds on Hermann Ebbinghaus's 1885 forgetting curve and on the spacing effect. Systems like the Leitner box, SuperMemo and Anki schedule reviews automatically. It is extremely efficient for vocabulary and characters but should support, not replace, real input.

Examples

Anki flashcards for 30 new hanzi a day; Leitner box with paper cards; WaniKani for kanji

Kungfucius says: Forget something, then remember it just in time. Repeat until your brain gives up and stores it.
