演示实验是物理课堂教学不可或缺的重要组成部分。演示实验是指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,以达到引入概念、理解规律的目的的实验教学方式。演示实验可以运用在物理课堂教学的各个环节中,教师在实验操作时一般都配以适当的讲解与引导,学生进行观察、操作、交流与讨论。根据课堂教学各环节功能的特点,演示实验可分为引入课题的演示实验,建立概念、发现规律的演示实验,巩固、深化概
Demonstration experiment is an indispensable part of physics classroom teaching. Demonstration experiment refers to the experimental teaching which is mainly operated by the teacher in the classroom and guided by the teacher’s inspiration to help students observe and think about the experiment in order to introduce the concept and understand the law. Demonstration experiments can be used in all aspects of physical classroom teaching, teachers in the experimental operation are generally accompanied by appropriate to explain and guide students to observe, operate, exchange and discussion. According to the characteristics of the various functions of the classroom teaching, the demonstration experiment can be divided into the demonstration experiment of introducing the subject, the establishment of the concept, the demonstration of the regular discovery experiment, consolidation and deepening
