物理学是一门以实验为基础的自然学科.物理学的发展离不开实验,在教学中如果能运用实验手段来研究问题,就能让学生获得直接经验,形成感性认识.而物理实验的器材资源不仅限于实验室的现有设备,我们身边的物品和器具等也是重要的实验资源.如果能充分地利用各种资源,巧妙地设计一些演示实验,就能激发学生的求知欲望,从而积极地接受新知识.下面,笔者结合一些教学案例,谈一谈多样化的演示实验.一、“游戏”实验俗话说:“水不激不活,人不激不奋.”提高课堂教 Physics is an experiment-based natural science.Development of physics can not be separated from experiment, if we can use experimental means to study the problem in teaching, we can let students gain direct experience and form perceptual knowledge. Equipment resources are not limited to the existing laboratory equipment, the items around us and appliances are also important experimental resources.If you can make full use of various resources, clever design of some demonstration experiments, we can stimulate students’ desire for knowledge, and thus active To accept the new knowledge .In the following, the author combines some teaching cases, talk about a variety of demonstration experiments. “Game ” experiment As the saying goes: “water is not intimidating, irritating people.” Classroom teaching
