What Is Spaced Repetition?

Spaced repetition leverages the 'spacing effect' — the finding that information is more effectively encoded in long-term memory when study sessions are spaced apart rather than concentrated. The technique uses algorithms to schedule review at optimal intervals, just before a learner would forget the material. Research shows spaced repetition can improve retention by 200% compared to massed study. In corporate training, this translates to better compliance knowledge retention, more effective onboarding, and reduced retraining costs.
