How to Learn

1. The Four Pillars of Learning

Attention: The basic threshold for learning; reduce distractions (turn off your phone, choose a conducive environment), focus through questioning and active participation.
Active Engagement: The brain is a predictor; actively operating, taking notes, etc., can trigger efficient cycles.
Error Feedback: Making mistakes is a sign of progress; feedback should be timely (exams, frequent testing).
Consolidation: Convert short-term memory into long-term memory through sleep (deep and REM sleep), with spaced repetition.

2. Practical Learning Methods and Strategies

Spaced Repetition: Distribute review sessions with increasing intervals (e.g., same day, after 1 day, 3 days, etc.).
Active Recall and Practice: Spend 30% of your time learning, 70% recalling and practicing.
Interleaved Practice: Work on different question types and concepts; it’s more efficient when questions are challenging.
Learn by Seeing Results: If you’re stuck after 20-30 seconds on a problem, look at the solution approach, then redo the problem, similar problems, or independent questions.
Timely and Specific Feedback: Find answers to wrong questions immediately; the more specific the feedback, the better.
Calibrate Your Understanding: Ask yourself if you can clearly teach it to others; only then have you truly learned it.
Create a Learning Environment: Reduce resistance (disconnect from the internet, have coffee, listen to music, find a study buddy).
Sleep: Ensure 7-9 hours; spend the last 10 minutes before sleep reviewing knowledge points to aid long-term memory.

3. Conclusion

Reason: Books contain experiments, case studies, and biological knowledge that videos cannot fully cover.
Key Point: The most important thing is to learn from experimental conclusions and adopt correct, efficient learning methods.
