Plane vector has an important role in the high school mathematics. The structure system of the chapter "Plane vector and its application" in the new textbook of human education edition has changed greatly. Based on ISM, this paper analyzes the specific changes of the "plane vector and its application" of the old and new textbooks, and compares them from four aspects: the selection of knowledge elements, the arrangement of the initial elements, the arrangement of the highest elements, the formation relationship between knowledge elements and the compilation system of textbooks. The results show that the new teaching material lays mo re emphasis on the integrity of knowledge elements; The new textbooks attach importance to the infiltration study of the essence of vector; The new textbook fully highlights the instrumental role of vector; The arrangement system of new textbooks lays more emphasis on the systematic learning of knowledge.
