中学化学教学大纲(修订草案)中明确地指出:“中学化学教学的主要任务有以下各点:使学生自觉地掌握巩固的、系统的化学基础知识;……。”在初中化学教学的过程中,必须特别注意基本概念的讲述。否则,学生难以学得巩固的化学知识;同时也会给高中化学的教学带来很大困难。在讲解初中化学的基本概念方面,我自下列的几点体验: 一、要生动地讲解抽象的理论例如“物质由分子构成”这一概念是不易为学生所接受的。为了使学生确信无疑地接受这一概念,在讲解时,并不是一开始就
High school chemistry syllabus (revised draft) made it clear: “The main task of chemistry teaching in high school has the following points: to enable students to consciously grasp the consolidated, systematic basic knowledge of chemistry; ......” In the process of junior high school chemistry teaching , Must pay special attention to the basic concept of narration. Otherwise, students will find it hard to learn more about chemistry; it will also cause great difficulties in high school chemistry teaching. In explaining the basic concepts of junior high school chemistry, I learned from the following points: First, to vividly explain abstract theories such as the concept of “matter formed by molecules” is not easy for students to accept. In order to convince the students that this concept is accepted without any doubt, it is not the beginning
