中学里的物理实验往往是在提出实验的要求以后,随即给出实验方案、实验原理、实验条件、操作步骤等内容,学生按部就班地完成实验.这种实验教学方法对于学生初步掌握物理实验基本知识和技能是必要的.作为教师可以进一步引导学生思考:这个实验为什么要这样安排?如果不看书,或者老师不事先告诉你,你会怎样想,怎样做?那么,学生的收获会更大些.在此思想的指导下,我们根据
The physics experiments in middle schools are often after submitting the requirements of the experiment, and then the contents of the experimental program, experimental principles, experimental conditions, and operation steps are given. The students complete the experiment step by step. This experimental teaching method provides students with a basic knowledge of physical experiments. Skills are necessary. As teachers can further guide students thinking: Why should this experiment be arranged? If you do not read books, or if the teacher does not tell you in advance, what would you think and how would you do? Then, the students’ gains will be greater. Under the guidance of this idea, we
