前言静电是中学物理教学内容中非常独特的一个部分,也是非常难教的一个部分。说它独特,在于这部分内容与其他部分的关联程度不大,相对孤立,且较为抽象;但因为它又是中学物理教学中少有的能将学生导向原子物理乃至量子论的基础知识,从这个意义上讲,静电内容不可或缺。说它难教,则在于静电的特性和传统实验仪器的限制,导致静电实验难做,教师的压力大。著名物理教学专家袁哲诚先生就在自己的《库仑定律》教案中强调:保持绝缘良好(包括空气干燥)和
Introduction Electrostatics is a very unique part of the physics teaching content in high school and a very difficult part to teach. To say that it is unique is that this part of the content is not related to any other part, relatively isolated and abstract. However, since it is also a rare basic knowledge in secondary school physics teaching that can lead students to atomic physics and even quantum theory, In this sense, static content is essential. To say that it is difficult to teach, lies in the characteristics of static electricity and the limitations of traditional experimental equipment, leading to difficult to do electrostatic experiments, teachers, pressure. Well-known physics teaching expert Mr. Yuan Zhecheng in his “Coulomb’s Law” lesson plans emphasize: to maintain good insulation (including air-dried) and
