初二物理的第二章讲到了参照物的概念,对于刚学物理的初中生来讲有一定的难度.我在教学中总结出初中物理关于参照物的题目可分为三类:一、两物体都静止;二、一物体运动、另一物体静止;三、两物体都运动.我摸索出用“三步曲”的方法去解这类题具有思路清晰,过程具体、学生易理解的特点. The second chapter of the second day of physics talked about the concept of reference objects. It is difficult for junior high school students who just studied physics. In my teaching, the topics of junior high school physics about reference objects can be divided into three categories: one or two. The objects are still; two, one object movement, another object is stationary; three or two objects are moving. I find out that using the “trilogy” method to solve such problems has clear thinking, specific process, students easy to understand specialty.
