Junior high school is a critical period for students. Many children get good grades in primary school and start to get confused as soon as they get to junior high school. Other children's grades in primary school were average, and junior high school suddenly began to understand, and then it was smooth sailing.

Here mainly refers to math scores, which determine academic performance.

Geometry is an important content in junior high school mathematics, and the learning methods are typical and representative. The previous article involves less knowledge of geometry and the learning method is rough. Here, let me explain it in detail. According to the method mentioned above, how to learn geometry knowledge in middle school.

The geometry knowledge in middle school textbooks is messy, with many definitions, terms and propositions, scattered content, lack of coherence and logic, which easily confuses students. Here I help you sort out the knowledge points and introduce how to learn.

Geometry is an abstraction of the shape, position and spatial form in reality, which ignores the differences of personality and only pays attention to the most fundamental characteristics. It is an imaginary perfect space.

For example, the concept of a straight line is abstracted from the edges of various straight trees and objects. From calculating the size of the land, the concept of plane is abstracted, and from the shapes of the moon and the sun, the concepts of circle and ball are abstracted.

Only by abstracting the perfect shape and spatial form can we study the characteristics and laws of shape and spatial form without the influence of individual differences of specific objects, and then apply what we have learned to practical occasions to get the most accurate approximation, such as measuring the size of land, calculating the amount of grain, comparing the height of big trees and so on.

Geometry is a typical axiomatic theory and the origin of axiomatic thought. All other propositions are derived from the simplest and most basic propositions. All our scientific theories must abide by this principle, otherwise it is not science, and it is difficult for the human brain to learn and apply.

Chinese medicine, for example, does not abide by this principle, and its knowledge is a hodgepodge of various prescriptions. A few theories come from Yin-Yang and Five Elements, and their concepts are vague, and the derivation process does not meet the most basic logical requirements, so it is extremely difficult to learn and apply.

Axiomatic thought is the origin and foundation of science. Only by axiomatizing knowledge can people learn and apply knowledge. Only a few memory geniuses can learn and only geniuses can apply hodgepodge of knowledge.

Most people can learn axiomatic knowledge, only need to recite a few propositions and deductive methods, and it is also handy to apply them. For specific problems, they can think of corresponding knowledge according to fixed logic to solve them.
