Glossary:Spaced repetition

spaced repetition (repetition spacing; expanded rehearsal)

technique of optimizing the learning process by computing optimum intervals that should separate repetitions of individual pieces of knowledge. Those pieces of knowledge are called elements in SuperMemo. SuperMemo pioneered the use of optimization methods in spaced repetition (first implemented in 1987) and has gained acclaim through its impact on the effectiveness of learning.
