Spaced Repetition
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Based on the Ebbinghaus forgetting curve, review at the critical point just before memory decays (e.g., 1 day, 3 days, 7 days, 15 days). Software like Anki is based on this principle. Scaffolding role: memory anti-aging. This is the only mathematical solution against forgetting. For key knowledge (such as cognitive scaffolds), a spaced repetition mechanism must be established, otherwise 90% will be returned to the teacher.
SCAFFOLDING EFFECT
Reduce cognitive load
Memory anti-aging. This is the only mathematical solution against forgetting. For key knowledge (such as cognitive scaffolds), a spaced repetition mechanism must be established, otherwise 90% will be returned to the teacher.
Anchor fast decisions
Review at the critical point just before forgetting, and repeat with gradually lengthening intervals, achieving long-term memory with the fewest repetitions. The system schedules reviews accordingly.
