观察实验是研究物理的根本方法之一,是学习知识过程中不可替代的重要实践活动.在人们的一般实践活动中,思维往往顺向行进.通过笔者多年教学发现,98%的学生上实验课,要么追随老师的动作或分析的过程,要么紧随教材之实验步骤,很少反过来,提出为什么要这样做或不这样做行不行的问题.下面笔者就实验中反思遵循的原则和提出反思问题的策略,结合人教社九义初中物理教材里的实验,谈谈自己的拙见.
Observing experiments is one of the fundamental methods for studying physics, and it is an irreplaceable important practical activity in the process of learning knowledge. In people’s general practice activities, thinking often goes in a straight line. By the author’s many years of teaching discovery, 98% of students have taken experimental courses. , Or follow the teacher’s action or analysis process, or follow the experimental steps of the teaching materials, seldom turn to the contrary, ask why you should do this or not do something that does not work. The following author’s reflect on the principles and reflect in the experiment The tactics of the problem, combined with the experiments in the physics textbooks of the junior high school ninja middle school teachers, talk about their own vision.
