笔者在组织物理必修2模块的复习教学时,使用了一道典型例题,教学中发现该题具有多方面教育功能:检查学生知识掌握情况,学生物理思维水平情况,学生思考问题方式和质疑能力等情况。现就该题教学过程及教学中的思维成果整理成文,供同仁们参考。原题图文:如图1所示,上表面有一段光滑圆弧的质量为M的小车A置于光滑平面上,在一质量为m的物体B自弧上端自由滑下的同时释放A,则
The author used two typical examples during the reviewing of compulsory 2 modules of physics compulsory education. The teaching found that the question has many educational functions: examining students ’knowledge, the level of students’ physical thinking, ways of students thinking and questioning ability . Now on the problem of teaching process and teaching the results of the finishing order, for my colleagues for reference. Original picture: As shown in Figure 1, the upper surface of a smooth arc mass M car A placed on a smooth plane, a mass m of the object B from the top of the arc free at the same time the release of A, then
