高中物理教学中,演示实验是新课导入的重要方法之一。演示实验一般只需要一套仪器,基本上是教师表演,学生观察。演示实验受到时间和空间的限制,一般只做定性实验。演示实验必须紧密配合课堂教学的目的要求进行,不是变魔术,为演示而演示。演示实验有利于培养学生的观察能力、思维能力和科学的思想方法,提高他们发现问题、分析问题和解决问题能力。
In high school physics teaching, demonstration experiment is one of the important ways to introduce new class. Demonstration experiment generally only need a set of equipment, basically teacher performance, student observation. Demonstration experiments by the time and space constraints, generally only qualitative experiments. Demonstration experiment must work closely with the requirements of classroom teaching, not magic, to demonstrate and demonstrate. Demonstration experiment is conducive to the development of students’ observation skills, thinking skills and scientific thinking, improve their ability to find problems, analyze problems and solve problems.
