物理学的研究对象大到宇宙,小到微观粒子,有的变化转瞬即逝,有的却悠悠漫长.在传统的物理课堂中,受场地、时间的限制,教师不得不用大量的语言向学生描述这些复杂的物理情景,不仅难以说清,而且效率低下,不易激发学生的学习兴趣.物理教学中一再强调要联系实际、仔细观察、认真思考.其中,仔细观察是重要的一环,而面对变化极快的过程,要仔细观察实在是异常困难.要解决这些问题,就需要选择合适的工具和方法.我国著名物理学家王义道教授在谈科学的方法时指出,人们研究一件事物,一般有两个要求:看清 In the traditional physical classroom, teachers are obliged to describe to students in a large number of languages, subject to the limitation of space and time. These complex physical situations are not only hard to say, but also inefficient, not easy to stimulate students’ interest in learning.Physical teaching has repeatedly stressed the need to connect with the actual, careful observation, serious thinking.Among them, careful observation is an important part, but the face In order to solve these problems, we need to choose the right tools and methods. Professor Wang Yidao, a famous physicist in our country, pointed out in his talk about the scientific method that people study a thing, generally There are two requirements: see
