全日制普通高级中学教科书 (修订本、必修 ,以下简称新教材 )第一册“牛顿第三定律”一节中 ,有一幅插图 ,如图 1所示 .翻阅历年来各种版本的高中物理教材 ,此图经历了两次改变 .新教材所用插图与甲种本中的插图一致 .笔者认为 ,该图作为教学示意图 ,不便向学生深入图 1分析和? There is an illustration in the first volume of “The Newton’s Third Law” in full-time ordinary high school textbooks (revised edition, compulsory, hereafter referred to as the new textbook), as shown in Figure 1. Throughout the years, various versions of high school physics textbooks have been read. This figure has undergone two changes. The illustrations used in the new textbook are consistent with the illustrations in the A. The author believes that this diagram is used as a schematic diagram of the teaching.
