实验教学是物理教学的重中之重.做好物理实验首先可以激发学生的学习兴趣.其次可以帮助学生理解物理知识,把抽象的事物演化成直观的物理现象,从而将复杂的问题简单化.此外,物理实验还可以培养学生的科学探究精神,在实验的过程中体会物理学的乐趣.所以做好实验,设计好实验是物理教学的重要一环.但是,目前课本上的一些实验效果不是很明显,对教学 Experimental teaching is the most important part of physics teaching.A good physical experiment can stimulate students’ interest in learning first.Secondly, it can help students to understand the physical knowledge and evolve abstract things into intuitive physical phenomena, thus simplifying the complicated problems. In addition, the physical experiment can also cultivate students’ spirit of scientific inquiry and experience the pleasure of physics in the process of experiment.Therefore, doing experiments and designing experiments is an important part of physics teaching.However, some experimental results in textbooks are not Obviously, for teaching
