物理学是一门以实验为基础的自然科学,而实验就是探索物理知识的源泉,加强实验教学是物理教学的时代特征,又是提高物理教学质量的先决条件。同样,实验也是形成物理概念、建立物理规律的重要方法,物理学习就是通过物理现象、过程获得必要的感性认识,这种感性认识可以来源于学生的生活,也可以来源于实验提供的物理事实。但有的实验存在着一定的缺陷,需要一些改进和重新设计,这就取决于教师自身对实验的把握。
Physics is an experiment-based natural science, and experiment is the source of exploring physical knowledge. Strengthening experimental teaching is a characteristic of the times in physics teaching and a prerequisite for improving the quality of physics teaching. Similarly, experiment is also an important way to form the concept of physics and establish laws of physics. Physical learning obtains the necessary perceptual knowledge through physical phenomena and processes. The perceptual knowledge can come from the life of students or from the physical facts provided by experiments. However, some experiments have certain flaws and need some improvement and redesign, which depends on the teacher’s own grasp of the experiment.
