Last month I have study a course on Coursera, it is called Learning how to learn. It is a course that teach you how to learn efficiently. I made some notes about it and share here. (I just list each view point which I think is important, but I think I can figure out better way to show next time)

Week 1 Two mode of your brain

1. Your brain has two mode: focus mode, diffuse mode.
2. Focus mode has tight spacing for the rubber bumpers.
3. Diffuse mode has more widely spaced bumpers.
4. If you need figure out a multiply problem you use your focus mode.
5. If you go for a walk, take a shower or drift off to sleep you go into diffuse mode.
6. Your memory is very important to learning.
7. There are four slots in your working memory. Working memory is like a not very good blackboard.
8. Long term memory is like a storage warehouse.
9. If you repeat and practice enough to change working memory to long term memory.
10. Don’t repeat many times in one day.
11. Sleeping is very important for learning. When you sleep, it will wash away the toxins in your brain.
12. Exercise is surprisingly valuable in helping improve both our memory and our ability of learn.

Week 2 Facts of brain
