初中化学所学内容从宏观到微观,知识点多而分散。由于学生刚接触化学学科,对学习化学的方法和规律尚不完全掌握,往往由于对某一知识点理解不深、不透,而造成思维上的障碍。表现在回答问题、作业乃至考题中常出现这样或那样的毛病和错误。为使学生能准确地、完整地理解并掌握各知识点,笔者从1990年开始初中化学知识点目标教学法的实验,学生成绩大面积提高,效果显著。
The content of junior middle school chemistry is from macroscopic to microscopic, and knowledge is scattered and scattered. As students are newly exposed to chemistry, they are still not fully aware of the methods and laws of learning chemistry, and they often cause obstacles in thinking because they do not understand or understand a particular point of knowledge. There are often problems or mistakes in the answers to questions, assignments, or even questions. In order to enable students to accurately and completely understand and grasp the knowledge points, the author started experimenting with the objective teaching method of junior high school chemistry knowledge point since 1990, and the students’ performance was greatly improved, and the effect was remarkable.
