实验是物理教学的重要内容,也是学生学习物理知识的重要手段,但是有些时候,由于实验条件的限制或实验本身的因素,有些实验的效果并非都非常理想,有的实验即使做了,现象也不是很明显,学生们也未必能够观察到老师所设想的效果,因此,利用一些辅助手段把实验现象定格化或夸张化,就会使学生比较明显地观察到我们所期望的效果。在多年的物理教学中,我认为使用多媒体就能够很好地解决上述问题。
Experiment is an important part of physics teaching and also an important means for students to learn physics knowledge. However, some experiments are not always ideal due to the limitation of experimental conditions or the factors of experiment itself. Even if some experiments are done, It is not obvious that the students may not be able to observe the effect envisaged by the teacher. Therefore, by using some auxiliary means to freeze or exaggerate the experimental phenomena, students are more likely to observe the effect we expect. In many years of physics teaching, I think that the use of multimedia will be able to solve these problems.
