摘  要：通过对人教版（2012版）初中化学教科书的分析，教材内容可分为三个领域：一、观察物质、了解其性质、描述其变化，要通过实验认识物质的变化及伴随着能量转化的现象；二、从分子、原子水平解释观察到的化学现象；三、要重视涉及和渗透到日常生活所有领域的化学知识。初中化学教材以化学核心知识为主，化学生活知识为辅。本文从物质的组成与结构、物质的化学变化、化学用语、物质的相互转化、物质的鉴定与鉴别、物质制备、溶液配制、化学实验、化学与生活、社会、安全知识、化学观念、化学思想与化学方法等来整理知识结构，使纷繁复杂又零碎的化学知识形成体系，为教师教学和学生学习提供帮助。

Research on Knowledge Structure System in New Chemistry Textbook of Junior Middle School

Abstract：Through the analyses of the junior high school chemistry textbook of the People's Education Press (2012 Edition), the content of the textbook could be pided into three areas.First, students should observe the substance, understand its nature, and describe its changes. It was necessary to know through experiments the changes in the material and the energy transformation. Second, students should explain the observed chemical phenomena from the molecular and atomic level.Third, we must pay attention to the chemical knowledge that involving and penetrating into all fields of daily life. Junior middle school chemistry textbooks were mainly based on chemical knowledge and supplemented by chemical life knowledge. From the composition and structure of matter, chemical changes in matter, chemical terms, mutual transformation of matter, identification and identification of substances, preparation of substances, solution preparation, chemical experiments, chemistry and life, society, safety knowledge, chemical ideas, chemical ideas and chemical methods, etc. these organized the knowledge structure.A variety of complex and fragmented chemical knowledge form of a system for teacher education and student learning to help.
