在物理教学中,为培养学生举一反三的能力,需要引导学生对一些典型习题进行开拓,把题目打开,让其所包含的物理过程全部摆出来,然后改变已知条件和所求问题,深入讨论,使一题变成多题。经常注意进行一题多用的训练,就能收到“学一题,会一类”的效果,与一题多解 In physics teaching, in order to cultivate students’ ability to perform inferences from others, we need to guide students in the development of some typical exercises, open the topics, put all the physical processes involved in them, and then change the known conditions and problems to be discussed in depth. Make the question more than one question. Often pay attention to a multi-purpose training, you can receive “study a problem, will be a class ” effect, and a solution
