为了使学生对化学名词术语要在理解的基础上进行记忆,我在讲解初中化学第二章的“分解作用”和“化合作用”时,采取启发学生的思考力,运用他们的理解力由他们自已来归纳定义。学生们大多数反映较好。现在我把讲课的基本过程写出来,以供大家研究和指正: 在讲解新课前的检查提问中,我安排了一个这样的问题:“什么样的现象叫做化学反应”在问答过程中,使全体学生回忆起“化学反应是‘物质改变了’的现象”。於是,教员即转入氧化汞分解的演示。演示中,教员着重交待“氧化汞是一种纯净物 In order to enable students to remember chemical terms on the basis of understanding, when I explain the “decomposition” and “compounding” of the second chapter of junior high school chemistry, I use the understanding of students to inspire Their own definition of induction. Most students reflect better. Now I wrote out the basic process of lectures for everyone to study and correct: In the examination of the new class before the question asked, I arranged a question like this: “What kind of phenomenon is called chemical reaction” in the process of question and answer, so that All students recalled “chemical reaction is the phenomenon of” material change “. As a result, the instructor turned to demonstration of oxidative mercury decomposition. In the demonstration, the instructor emphasized that ”mercury oxide is a pure substance
