Spaced Repetition

Spaced repetition is a learning technique in which increasing intervals of time are used between subsequent reviews. Alternative names include expanding rehearsal, graduated intervals, repetition spacing, repetition scheduling, spaced retrieval and expanded retrieval. Spaced repetition is not simple rote repetition of phrases. It emphasizes active recall rather than recognition, and uses recall methods of memory such as questioning, free recall, free association, intellective reflection, or prompting using other mnemonic triggers or cues.
