大学物理课堂演示实验应定位在科学性实验

The University Physics Classroom Demonstration Experiment Should be Positioned in Scientific Experiments

目前大学物理课堂教学中演示实验通常用于演示物理现象，没有充分发挥出演示实验的作用．本文指出，演示实验应定位在科学性实验．为此，课堂演示实验的设计要体现出物理的严密性、科学性，在验证理论知识的同时，让学生也学会科学的分析方法与实验方法．学生应作为大学物理演示实验的主体，参与到演示实验的操作、数据采集、分析中；教师在课堂教学中主要是提出问题、启发思路和引导争论，充当实验操作员与引导学生的角色．

At present, the demonstration experiment of college physics is often used to demonstrate the physical phenomenon, which doesn＇t fully play the role of the demonstration experiment. Demonstration experiment should be positioned in scientific experiments. The classroom demonstration experiment design should reflect the strictness and scientific nature. The demonstration experiment not only verifies the theory knowledge, but also lets students learn the scientific analysis method and experimental method. As the main body of college physics demonstration experiment, students should participate in the demonstration experiment operation, data acquisition and analysis Teachers in the classroom is mainly to question, inspire thinking and guide the debate, and acts as the experiment operator and guides the student
