As for mathematics, I think every curriculum reform is reflected in two aspects: one is to reduce the difficulty, and the other is to further strengthen the connection between mathematics and life practice. As far as the difficulty is concerned, there will be no complicated calculation and boring simple geometric proof as before. As long as students have calculations and ideas, this is enough, which is good for students. Mathematics comes from practice, and the purpose of our study is to apply it to our daily life, so now mathematics is closely related to our daily life. For example, in the past, we took the scientific notation, and directly took the test: 3000000000, which was expressed as _ _ _ _ _ _ _ _ by scientific notation. Now let's do a problem like this: the propagation speed of light is 3000000000 m/s, which is expressed by scientific notation.
I hope my answer is helpful to you!
