A lot of practice has proved that the knowledge after understanding is easy to remember and unforgettable. It can be seen that understanding is the premise and foundation of memory.
If you want to review your lessons well, you must first digest the knowledge, which requires students to concentrate on the classroom and understand the classroom. The problems of the day should be solved on the same day and never put off until the next day.
Ebbinghaus, a famous psychologist, found that people can only remember 44% of new knowledge after one hour, 28% after two days and 25% after six days.
These data show that knowledge is forgotten quickly after learning. After a long time, although the memory retention is reduced, the speed of forgetting is also slow. That is, the law of forgetting is: first fast, then slow, first more, then less.
