At a maths-ed workshop I attended recently, one of the other participants (unfortunately I don’t recall who) quoted a piece of advice which neatly sums up the educational benefits of self-explanation, peer instruction, and what I’m just going to call my day job:
If you really want to understand something, there are three steps.
- Explain it to yourself.
- Explain it to a friend.
- Explain it to an enemy.
If anyone knows who should be given the credit for this, please let me know…
