教给学生复习物理概念和规律的方法。要让学生清楚引入这个概念的必要性,明白物理概念的定义式、度量式是怎样规定的,物理量的单位是什么。例如,压力的作用效果与压力大小和受力面积大小有关,因此为了方便比较,我们用单位面积上所受压力来反映,从而得到了压强概念及压强定义式P=F/S。其他如密度、速度、功率等都可让学生依此自主复习以加深理解。 列表总结,强化记忆。应引导学生在通读教材的基础上按力、热、
Teach students how to review physical concepts and laws. Let the students clearly understand the necessity of introducing this concept, understand how the definition of the physical concept, the metrics are defined, and what is the unit of the physical quantity. For example, the effect of pressure is related to the size of the pressure and the size of the force area. Therefore, to facilitate the comparison, we use the pressure on the unit area to reflect the pressure concept and the pressure definition formula P=F/S. Others such as density, speed, power, etc. can allow students to independently review to deepen their understanding. List summary, strengthen memory. Students should be guided on the basis of reading the teaching materials
