高中化学第一册教材的特点是理论性强,起点高,有关元素及其化合物知识比较复杂。根据高一化学教材的特点和要求,就我们的教学体会,提出几点关于抓好复习教学的意见。一、加强知识的系统化高一化学教材,大体上可以分为两部分:基础理论和元素化合物知识。它的体系基本上是以物质结构理论为主线。因此,加强知识系统化,首先要以物质结构等基础理论作指导,把若干族元素化合物的具体知识(这里先侧重于非金属主族元素)联系起来,统一起来。例如,学生已学习了氧族、氮族和碳族,结合初中已学过的卤族元素,总复习时,可以选择硅、硫、磷、氯四种元素,讨论以下几个复习题:(题目可预先布置给学生复习思考)
The characteristics of the textbooks in High School Chemistry Book 1 are strong in theory, high in starting points, and the knowledge of related elements and their compounds is more complicated. According to the characteristics and requirements of the chemistry textbooks for senior high school students, we made several suggestions on how to grasp the teaching of recitation. First, to strengthen the systematization of knowledge Chemistry textbooks, in general, can be divided into two parts: basic theory and knowledge of elemental compounds. Its system is basically based on the theory of material structure. Therefore, to strengthen the knowledge systematization, we must first use the basic theory of the material structure as a guide, and combine the specific knowledge of several groups of elemental compounds (here, first focusing on non-metallic main group elements). For example, students have learned about oxygen, nitrogen, and carbon, combined with halogen elements that have been studied in junior high school. When reviewing, they can choose four elements: silicon, sulfur, phosphorus, and chlorine. Discuss the following review questions: Topics can be pre-arranged for students to review
