1. Forgetting Curve Can Be Quantified
- Without review, memory retention is approximately 58% after 20 minutes
- Approximately 66% after 1 day
- Approximately 80% after 1 week
2. Active Recall is Better Than Passive Review
- Research shows self-testing nearly doubles memory retention compared to re-reading
3. Spaced Repetition is Effective
- Review with increasing intervals (5-30 minutes, 1 day, 1 week, 1 month)
4. Tools Like Anki are Effective
- Medical education research shows Anki usage frequency is positively correlated with test performance
5. Understanding Before Memorization
- Knowledge with a conceptual framework lasts longer than isolated facts
6. Output Strengthens Learning
- Teaching, blogging, code sharing creates stronger memory traces than passive consumption
7. Manage Learning Pace
- Distributed practice (short, regular sessions) is better than cramming
8. Reduce Search Dependency
- Try recalling before searching to build stronger internal knowledge
Core Perspective
“Forgetting is controllable, not inevitable. The key is using scientific strategies to smooth the forgetting curve.”
