The science behind it
Memory follows a forgetting curve: we lose newly learned information quickly unless we revisit it. Spaced repetition times each review to land just as memory starts to fade, which strengthens recall with each successful retrieval and stretches the interval before the next review.
Spaced repetition in an LMS
A learning platform can automate this by tracking which flashcards or passages a student struggled with and re-surfacing them on an optimised schedule, while letting well-known items appear less often — so study time concentrates where it is needed.
Pairing with active recall
Spaced repetition is most powerful when combined with active recall — testing yourself rather than re-reading. The platform schedules the review; active recall makes each review count.
Frequently asked questions
What is spaced repetition?
Spaced repetition is a study technique that schedules reviews at increasing intervals — just before you would forget — to move knowledge into long-term memory more efficiently than cramming.
Does spaced repetition work for exam prep?
Yes. Scheduling reviews of weak material at optimal intervals improves long-term retention, which is what high-stakes exams test.
