Spaced repetition is a learning technique where review sessions are scheduled at increasing intervals. Instead of cramming everything in one sitting, you revisit material just before you would forget it, strengthening memory each time.
The method is grounded in the forgetting curve, first described by Hermann Ebbinghaus in 1885. Without review, newly learned information decays exponentially. Spaced repetition algorithms (like SM-2, used in Anki and adapted in most modern tools) calculate the optimal moment to review each item based on your past performance. Items you find easy get pushed further out; items you struggle with appear more frequently. Research consistently shows that spaced practice produces better long-term retention than massed practice (cramming), even when total study time is equal.
StudyCheetah's flashcard system uses spaced repetition scheduling. When you review a card and mark it as 'know' or 'don't know,' the algorithm adjusts when you'll see it next. Cards you miss appear sooner; cards you know well appear days or weeks later. Your dashboard shows how many cards are due each day, so you always know what to review.
Active Recall — Active recall is the practice of retrieving information from memory without looking at the answer.
Testing Effect — The testing effect is the finding that retrieving information from memory (being tested) produces stronger long-term retention than simply re-studying the same material for an equal amount of time.
Forgetting Curve — The forgetting curve describes the exponential decline of memory retention over time when no effort is made to review the material.
Distributed Practice — Distributed practice means spreading study sessions over multiple days rather than concentrating them in a single long session.
Understanding spaced repetition is the first step. Here's how to apply it today:
