物理学是一门以实验为基础的学科,物理实验是研究物理现象的基本方法。物理实验是培养学生观察、动手、思维能力的重要手段,是完成教学活动必不可少的环节,实验在中学物理教学中占有重要位置。从教学的角度考虑,物理实验可以分为演示实验、学生分组实验和课外实验三大类。在日常教学中适当地进行各种实验,对学生的学科学习具有重要的意义。演示实验是最常用、最直接、最基本的物理实验,因此,在常规教学中做好演示实验意义重大。
Physics is an experiment-based discipline, and physics experiments are the basic methods for studying physical phenomena. Physics experiment is an important means to cultivate students’ ability of observation, hands-on, and thinking. It is an indispensable link in the completion of teaching activities. Experiments play an important role in physics teaching in middle schools. From the teaching point of view, physical experiments can be divided into three categories: demonstration experiment, student grouping experiment and extracurricular experiment. Conducting various experiments properly in everyday teaching is of great significance to students’ subject learning. Demonstration experiment is the most common, most direct and basic physical experiment. Therefore, it is of great significance to do demonstration experiments in regular teaching.
