初中化学教材的内容比较广泛,具有一定的普及性与完整性,由于化学自身的特性及教材编排体系的特点可以看出对其中各知识点的教学不应是孤立的。在教学实践中,各知识点之间的联系是广泛的,相互间形成了一个逻辑系统很强的网络,如果我们在教学中强化这一意识,会使学生全面而系统地掌握化学基础知识与基本技能。我们可以把教材中各知识点之间的关联分为以下5种类型。
The contents of junior middle school chemistry textbooks are relatively extensive, and they have a certain degree of popularity and completeness. Because of the characteristics of chemistry and the characteristics of the teaching material arrangement system, it can be seen that the teaching of each knowledge point should not be isolated. In the teaching practice, the connection between various knowledge points is extensive and forms a strong network of logic systems. If we strengthen this awareness in teaching, students will be able to master the basic knowledge of chemistry comprehensively and systematically. basic skills. We can divide the relationship between the knowledge points in the textbook into the following five types.
