为了加深学生对透镜成像这部分知识的理解和掌握,使他们能利用所学知识来熟练解题,本人在教学实践中采用了:先利用列表的方式,带领学生对原有的知识作简明扼要的回顾,然后,再用图像的方式,对一些学生普通感到疑难的问题进行分析和总结的复习方式。通过这样的复习,学生在解决一些具体问题时便感到更加的方便和快捷。 In order to deepen students’ understanding and mastery of this part of the lens imaging knowledge, they can use the knowledge they have learned to solve the problem proficiently. I have adopted it in teaching practice: first, use the list method to lead the students to make concise briefs on the original knowledge. After reviewing, and then using the image method to analyze and summarize some of the problems that students often find difficult to review. Through this review, students feel more convenient and faster when solving specific problems.
