Spaced repetition is a general idea that can be combined with any mode of review. For instance, spaced repetition may be done using a [[quiz and recall]] strategy: a list of questions and answers is generated during the original study (or obtained from elsewhere) and the learner quizzes himself or herself using that list of questions after the appropriately spaced intervals. Spaced repetition may also use more active forms of recall (such as trying to reconstruct the whole knowledge base without any cues at all) or more passive forms or recall (such as reading through the learning material again).

Spaced repetition is an approach where material is reviewed at strategic time intervals so as to increase the strength of recall as much as possible. The general idea is to space out the intervals for reviewing the material with the gap between successive review intervals growing exponentially. The theoretical rationale for increasing the spacing between successive recalls is that the forgetting curve decays exponentially. Each attempt at recall increases the strength of the memory, therefore combating the forgetting curve.

Spaced repetition is a general idea that can be combined with any mode of review.

Systems of spaced repetition

  • Leitner system is a simple system that can be implemented relatively easily without computer assistance.
  • The Pimsleur language learning system uses a version of spaced repetition.
  • Anki is a popular computer software that implements spaced repetition with digital flashcards.
