课堂教学应尽量让学生多动、多想、多议,使他们主动获得知识,发展智能。为此,我在初三化学教学中,注意从以下几方面入手。一、让学生自己整理知识,教师变“主演”为“导演”。我经常遇到一些学生向我倾诉:初中化学内容杂,无头绪,难理清条理。针对这种情况,我尝试让学生自己动手进行归纳,使他们在整理知识的过程中自觉把握教材的主线和脉胳。每学完一章,我就引导学生按基本概念(全部黑体字)、化学方程式、基本实验(包括原理、装置图、操作步骤、现象、注意事项)、化学计算进行分类。然后在专用的笔记本上将其系统归纳。这样,当全册 Classroom teaching should try to make students more active, more thoughts and more discussions, so that they can actively acquire knowledge and develop intelligence. For this reason, in the chemistry teaching of junior high school, I pay attention to the following aspects. First, let the students organize their own knowledge, teachers become “starring” as “director.” I often meet some students who confided to me: junior high school chemistry is miscellaneous, with no clue, it is difficult to sort out the rules. In response to this situation, I try to let students do their own induction, so that they consciously grasp the main line and pulse of the teaching materials in the process of finishing knowledge. After each chapter is completed, I will guide students to classify them according to basic concepts (all bold type), chemical equations, basic experiments (including principles, device diagrams, operating procedures, phenomena, precautions), and chemical calculations. Then summarize the system on a dedicated notebook. In this way, when the whole book
