Research on Structured Teaching of New Textbooks Based on the ISM Method—The Example of "Vegetation and Soil" of the Humanistic Education Edition

This paper adopts the ISM method to study the structured teaching of the chapter "Vegetation and Soil" in the Humanistic Version of High School Geography Compulsory 1. The knowledge structure of the textbook was analyzed by extracting the core elements, determining the relationships of the elements, establishing the adjacency matrix, forming the hierarchical distribution table and constructing the systematic hierarchical directed graph. Based on the analysis results, a sequence of teaching activities and a unit teaching framework were designed, aiming to help students construct a systematic knowledge system. The structured analysis of the content of this chapter using the ISM method can clarify the hierarchical relationship between the geographic elements and determine the teaching sequence of each element accordingly, which can provide certain reference for the teaching of high school geography courses and the analysis of geography teaching materials.
