第一章“光的初步知识” 由于教学计划的改变和大家对《试用本》的反映,需要在高中讲点几何光学。原来在初中讲的折射定律、全反射、凸透镜成像作图法、凸透镜公式等内容都将移到高中去讲。因此,新编的初三物理课本,光学知识只有这一章,教学内容比较少,要求也比较低。教学时,应注意按
The first chapter The refraction laws, total reflections, convex lens imaging, and convex lens formulas that were originally mentioned in junior high schools will all be moved to high school to speak. Therefore, in the newly-edited junior high school physics textbook, only one chapter of optical knowledge is available, and the teaching content is relatively small and the requirements are relatively low. When teaching, pay attention to
