To cultivate interest in mathematics, read more stories about mathematicians and read more books about the history of mathematics. Secondly, we should learn to think independently, try to solve some mathematical problems and improve our mathematical creativity. For example, Mr. Yang Shiming, an expert in elementary mathematics, put forward a conjecture about the self-intersection number of plane closed broken lines. I have done in-depth research and found several theorems for constructing plane self-intersection numbers. This achievement was later published in China Elementary Mathematics Research Collection (II), which greatly aroused my interest in learning and studying mathematics. Finally, we should insist on doing more math problems, for example, junior high school math teachers should do more math finale problems in the senior high school entrance examination, study math problems in the senior high school entrance examination, and understand the direction of teaching and research. At the same time, you can learn some math software, such as learning to make math courseware for primary and secondary schools with geometric sketchpad, learning to integrate math teaching ability with geometric sketchpad, and improving the ability to solve math problems with information technology.
