演示实验教学,是在课堂上主要由教师操作,并通过教师的启发引导,帮助学生对实验进行观察思考,以达到一定教学目的的实验教学方式.演示实验是物理教学中重要的组成部分.通过演示实验教学,可以指导学生观察和分析物理现象,获得生动的感性知识,从而更好地掌握物理概念和规律;还可以培养学生的观察和分析能力、逻辑思维能力和探索发现的能力.下面,笔者择取在教学实践中积累的鲜活案例,对演示实验的教学功能展开剖析.
Demonstration experiment teaching is a kind of experimental teaching method that is mainly operated by teachers in the classroom and guided by teachers to help students observe and think about experiments in order to achieve a certain teaching purpose.Demonstration experiment is an important part of physics teaching. Demonstration of experimental teaching, students can guide the observation and analysis of physical phenomena, access to vivid emotional knowledge, so as to better grasp the concepts and laws of physics, but also to develop students’ ability of observation and analysis, logical thinking and exploring the ability to explore the following, The author chooses fresh cases accumulated in teaching practice and analyzes the teaching function of demonstration experiment.
