1, integrating knowledge points

Compared with the original textbook, the knowledge points and system of the new textbook are more concentrated, and the classification between modules is clear, which is convenient for students to understand and practice.

The difficulty is obvious.

After the reform, the textbook defines the compulsory volumes 1 and 2 as basic exercises, so that students can complete the basic mathematics knowledge exercises in senior high school in the compulsory stage and help students complete the connection and transformation between junior high school and senior high school from the first year of senior high school. At the same time, the pressure of students gradually shifted to the elective part.

In the future teaching, senior one is likely to complete the compulsory study of one or two, and senior two will begin to take elective courses. In this way, from the second year of high school, the difficulty gradually increased.

3. Pay attention to basic exercises and applications.

As can be seen from the textbook, the textbook writers attach importance to the examination of basic knowledge and the infiltration of mathematical culture. Each chapter is followed by similar practical application or related exploration of mathematical culture, which shows that the application ability of mathematical knowledge is a trend in the future.
