Advantages and Disadvantages of Old and New Mathematics Textbooks for Senior High School
The old textbooks run through the rigor and systematicness of knowledge and the accuracy of concepts, such as analytic geometry, starting from a straight line and talking about parabola.

The new textbook runs through the concept of desalination, introduces knowledge and concepts from the perspective of being close to life or experiment, and divides some knowledge into two parts. The first part is about preliminary study, and the second part is about further study of elective courses. Systematization is broken and knowledge spirals up.
