Comparative Research On The Structure Of High School Physics Teaching Material Based On ISM

Based on the 2017 version of the general high school physics curriculum standard and the core literacy concept of physics as the core,a comprehensive revised general high school physics textbook has been officially published in 2019.The 2019 version of the high school physics textbook is an important carrier of educational goals and educational content,and it is a grand blueprint for nurturing people.This article takes the mechanics modules of the 2019 edition of the People's Education Edition textbook and the textbook version of the ordinary high school physics textbook as the research object,and uses the ISM method to focus on the four aspects of key element selection,starting element arrangement,node element arrangement,and element formation path.Comparative analysis of the structure of the textbook reveals the structural characteristics of different versions of textbooks.The research shows that the similarities and differences between the two editions of textbooks are as follows:1.Both editions of the textbooks focus on the basic and contemporary nature of the knowledge content;2.Both editions of the textbooks focus on the integrity and systematicity of the knowledge structure;3.The development paths of the two versions of the textbooks are different.By comparing the similarities and differences between the two editions of textbooks,it is intended to help textbook users understand the structural features and usage of physics textbooks in the context of the new curriculum reform,so that first-line physics teachers can promptly change their education concepts and accelerate the achievement of students' core literacy.
