物理学是一门实验科学,恰当地设计学生实验或演示实验,既能培养学生的观察实验能力,又使他们懂得物理学研究的基本方法.中学生对感性认识接受较快,印象深,记忆牢固.物理教学中的某些结论学生难以接受,即使记下来,也不能理解,很快忘记.所以可通过实验让学生对学过的知识铭刻在心.一、培养学生的兴趣和激发学生的求知欲设计实验,要有针对性,既要直观,又要使效果或现象明显.否则,不但问题没有得到解决,反而把简单的问题搞得复 Physics is an experimental science, the proper design of student experiments or demonstration experiments, both to develop students’ ability to observe experiments, but also to enable them to understand the basic methods of physics research.Secondary students accept the perception of perceptualFast, impressed, solid memory Some conclusions in the teaching of physics students unacceptable, even if you write down, you can not understand, quickly forget, so students can learn by experiment learned knowledge in. First, to develop students ’interest and stimulate students’ curiosity Design experiments should be targeted, it is necessary to be intuitive, but also to make the effect or phenomenon obvious. Otherwise, not only the problem has not been resolved, but the simple problem and make complex
