It is difficult to change the mathematics from Beijing Normal University to Soviet Education. Mathematics published by Beijing Normal University has been changed to Jiangsu Education Edition, and the mathematics textbook published by Beijing Normal University focuses on cultivating students' ability to think and solve problems independently. The teaching content is closely related to the theoretical structure and scientific thinking of mathematics itself. However, the mathematics textbook of Jiangsu Education Edition focuses on cultivating students' computing ability and practical application ability, and the teaching content is related to exercises and questions. Therefore, the first day and the second day are very difficult.
