This pdf is a must read. It is just 6 pages.
It is done by professor dunlosky, who has gone through many studies on efficient learning techniques and summarized it in this paper.
Most Efficient
1. Active Recall
2. Spaced Repetition
3. Interleaved Learning
Least Efficient
1. Rereading
2. Highlighting
3. Note Making or Summarizing
I find that even the least efficient methods have some or the other utility, especially in the initial stages of collating information. But thanks for the interesting read, I’m sure I’ll find utility for it in my B.Ed classes 😅
