在参加物理大家学堂中,聆听了一节“压强”展示课.在教学过程中生成了常见的一幕,笔者分析这一幕后,发现了不一样的隐性价值,在此和大家交流,欲以此抛砖引玉.1课堂原型学生在展示探究压力作用效果与受力面积和压力大小的关系时,学生第一步已经通过探究得出:当受力面积一定时,压力越大,压力作用效果越明显.随之探究压力作用效果与受力面积的关系,学生进行了如下操作:将一个钩码放在沙子上,钩 In attending physics everyone in the school, listening to a In the teaching process to generate a common scene, the author analysis of this scene, found a different hidden value, and here to communicate, In order to attract scholarship.1 The prototype students in the classroom demonstrate the effect of pressure and stress area and the size of the relationship between the pressure, the students first step has been drawn through exploration: when the force area, the greater the pressure, the effect of stress The more obvious.Seeing the relationship between the effect of stress and stress area, the students conducted the following operations: a hook code on the sand, the hook
