物理学是一门以观察、实验为基础的学科,演示实验是物理教学的重要组成部分,在教学中有着举足轻重的地位。从演示实验的作用来看,大致可分为导入课题、得出结论、原理应用等三种类型。在实际教学中,如果对教材提供的演示实验不加取舍,一概照本宣科,就会受到实验设计及实验装置等方面因素的制约,使学生在学习中产生被动性或神秘感,造成对概念或规律一知半解,甚至扼杀学生的创造性。在教学中,要对演示实验进行适当的处理,从而提高学生 Physics is a subject based on observation and experiment. Demonstration experiment is an important part of physics teaching and plays a decisive role in teaching. From the role of demonstration experiments, can be divided into the introduction of topics, conclusions, principles and other three types of applications. In the actual teaching, if there is no choice of demonstration experiment for the teaching materials, all of them will be subject to the experimental design and experimental device, which will make students feel passive or mysterious in their study, resulting in the change of concept or law Little knowledge, even stifling the creativity of students. In teaching, demonstration experiments should be properly handled to improve students
