物理实验是人们根据研究目的,运用科学仪器设备,人为地控制、创造或纯化某种自然过程,使之按预期的过程发展,同时在尽可能减小客观状态干扰的前提下进行观测,以探究物理过程变化规律的一种科学活动。实验所得到的事实不但给思维活动提供了原始材料和主要依据,而且是检验思维正确与否的标准。在教学中有目的、有计划和有成效地进行实验,不但可以激发学生思维,而且可以多方面训练学生思维,从而培养他们正确
Physical experiment is based on the purpose of research, the use of scientific instruments and equipment, people artificially control, create or purify a natural process, so that the process of development as expected, while minimizing the objective state interference under the premise of observations to explore A scientific activity that changes the law of the physical process. The fact that the experiment obtains not only provides the original material and the main basis for the thinking activity, but also is the standard to test whether the thinking is correct or not. There is a purpose in teaching, a planned and effective experiment, not only can stimulate students ’thinking, but also can train students’ thinking in many aspects so as to cultivate them correctly
