物理学中所研究的内容,都是前人对客观世界中的事物进行观察、归纳和推理后得到的结论,我们现在要使学生牢固地掌握这些物理知识,仍有必要让他们深入地观察客观事物中的物理现象,懂得现象的内部联系。在这中间,实验有着极重要的作用。在实验过程中,我们可以挑选出自然界中的典型现象,加以控制或使之强化,排除许多偶然因素的干扰,把复杂的自然现象分析成若干单独的现象,根据需要,使所欲观察的现象重复地出现,便于对学生讲清楚事物在某一方面变化发展的因果关系。所以,做好物理实验,是提高物理教学质量的一个很重要的步骤。
What we study in physics are all the conclusions we got after observing, inducing and reasoning the things in the objective world before. Now, to enable students to grasp these physical knowledge firmly, it is still necessary for them to observe objectively in depth Physical phenomena in things, understand the internal relations of phenomena. In the middle of this experiment has a very important role. During the experiment, we can pick out the typical phenomena in nature, control or strengthen it, eliminate the interference of many accidental factors, analyze the complicated natural phenomena into several separate phenomena, and make the phenomena to be observed Repeatedly appear to make it easier for students to clarify the causal relationship between things in a certain area of change and development. Therefore, doing a good job in physics experiments is a very important step to improve the quality of physics teaching.
