Exploration of Essential Knowledge in Chinese Senior Middle School Mathematics
Essential knowledge refers to the basic and universal knowledge that students have accumulated in their longterm learning; The principle of exploration is to rely on the curriculum standards for breadth and the textbooks for depth. In China, the vast majority of essential mathematical knowledge is presented in the form of knowledge points in the curriculum standards. The necessary knowledge of marginality, in terms of breadth, should be intersection for the connection between junior middle school and senior middle school. The marked content should be based on the needs of the university and the wide use of high school, and infiltration knowledge should be defined as “entering the dictionary”; In terms of depth, what is clearly provided in the textbook is essential knowledge. For those who appear in other forms of the same textbook, the “Triple degree ” are used to define essential knowledge. For those who penetrate the same textbook or have different textbook settings, they are defined in a unioned manner. Generalization and inclusion are the overall methods for determining essential knowledge.
