物理学是一门以实验为基础的自然科学,中学物理中大多数的基本概念和定律、理论都是通过观察、实验,然后分析概括出来的。演示和学生实验在中学物理教学中十分重要,许多物理现象、原理、定律,如果教师只在讲台上反复讲解,在黑板上进行图解,学生往往不能理解和掌握,实践证明,课堂实验是中学物理教学的重要手段,通过演示和学生实验既能使学生深刻理解物理概念和规律,又能提高课堂效果。下面我就从以下几方面谈谈课堂实验的方式、做法和教法。一、用引导性、启发性的演示实验引入新课教师从启发性演示实验开始引入新课,不但能
Physics is an experiment-based natural science, most of the basic concepts and laws in high school physics, the theory is summarized by observation, experiment, and then analysis. Demonstrations and student experiments are very important in secondary school physics teaching. Many physical phenomena, principles and laws are often not understood or mastered by students if they are repeatedly explained on the podium and illustrated on a blackboard. Practice has proved that classroom experiments are secondary school physics Teaching an important means, through demonstrations and student experiments both enable students to deeply understand the concept of physics and laws, but also improve the classroom effect. Below I will talk about the following aspects of the classroom experiment, practices and teaching methods. I. Introducing New Class Teachers with Guided and Enlightening Demonstration Experiments Introducing new lessons from inspiring demonstration experiments, not only can
