光学知识在初中物理中课时比例不大,但涉及到了光学的三个重要规律。对这部分知识的考察主要体现在概念的把握和实际应用上。为了让学生扎扎实实的掌握这部分内容,笔者尝试着将实验探索的学习方式应用到复习中去,收到了较好的效果。下面就谈一谈在实施过程中的一些体会和感受。一、通过实验探索,串起每个小的知识点,有利于形成准确的概念既然是复习,就要充分利用学生头脑中已经存在的知识印象,再结合日常教学中学生没有掌握好的薄弱环节,设计有针对性的小实验。当然,在这里设计的实验不同于新课
Optical knowledge in junior high school hours in physics is not large, but involves the three important laws of optics. The investigation of this part of knowledge is mainly reflected in the grasp of the concept and practical application. In order to let students have a solid grasp of this part of the content, the author tries to apply the experimental exploration of learning methods to review, received good results. Here to talk about some of the experience in the implementation process and feelings. First, through the experiment to explore, strung each small knowledge points conducive to the formation of an accurate concept Since it is a review, we must make full use of the minds already exist in the student’s impression of knowledge, combined with daily teaching students do not have a good grasp of the weak links, Design targeted small experiments. Of course, the experiment designed here is different from the new one
