一、实验讨论,导出规律我把部分演示实验改为学生实验,以利于学生对物理概念的理解。例如,在“牛顿第一运动定律”一节教学中,我让学生按教材做实验,提出小车通过的距离与摩擦力大小的关系,然后假设:小车在越来越光滑的平面上运动情况又如何呢?这样,从感性认识逐步上升到 First, the experimental discussion, the law of derivation I put some demonstration experiments into student experiments, in order to facilitate students to understand the concept of physics. For example, in the teaching of “Newton’s First Law of Motion”, I asked students to experiment with the teaching materials and put forward the relationship between the distance and the frictional force through which the car passes, and then assume that the car is moving in a more and more smooth plane What is the situation? In this way, from the perceptual awareness gradually increased to
