Active recall is a method that lets learners retrieve previously learned information from their minds. This type of recall is concentrated on the active effort of retrieving the information from memory instead of merely reviewing it. Some synonyms for active recall include "retrieval practice," "spaced repetition," and "memory consolidation." Retrieval practice entails consciously attempting to remember the information that has been learned previously; spaced repetition is the method of spacing out the practice sessions to keep the learned information fresh in one's mind, and memory consolidation is the process of strengthening the retrieval paths in the brain of newly learned information. Using any of these synonyms, students can improve their retention and recall what they've learned.
