To write a good observation diary, we must pay attention to:

(1) The observation purpose should be clear. Observation has many purposes, or accumulates writing materials; Or used in scientific experiments; Or to find out some kind of "mystery" ... Only when the purpose is clear, can observation have direction and focus. Is to observe the same object, because the purpose is different, the method and angle are different, and the result is different.

(2) observation should be comprehensive and meticulous. To be comprehensive is to observe the whole process of the development of things, the components of things and the relationship between things; Meticulousness means observing thoroughly and grasping the characteristics, laws and essence of proverbs.

(3) Keep observing. It is difficult to observe things at once, and it needs to be observed repeatedly. This requires students to have perseverance.
