在现行的人教版高中物理选修3-1静电场一章的教学中,学生普遍感觉概念抽象,学习容易脱离实际,对一些物理量的数量级也缺乏基本了解,学生难以解决实际的物理问题。遍览本章,在教材编排上,编者的意图显然是将全章分为电荷、电场、应用三个单元,第一单元也就是前两节,重在建立电荷的概念,学习电荷的相关规律,学生学习相对容易。第三单元也就是最后三节,重在应用电场知识,进一步学习静电现象,学习电容和带电粒子在电场中的运动,由于有较多的演示实验、探究实验和课外阅读,学生学习起来也相对容易。唯独第二单元中的《电场强度》
In the current PEP physical education elective 3-1 chapter electrostatic field teaching, students generally feel the concept of abstraction, easy to learn from reality, the magnitude of some physical quantities also lack a basic understanding of students difficult to solve the actual physical problems. Throughout this chapter, in the textbook layout, the editor’s intent is clearly the whole chapter is divided into charge, electric field, the application of three units, the first unit is the first two sections, focusing on the concept of charge, learning charge related laws, Students learn relatively easily. The third unit is the last three sections, focusing on the application of electric field knowledge, to further learn static phenomena, learning capacitance and charged particles in the electric field in the movement, due to more demonstration experiments, exploration experiments and extracurricular reading, students learn relatively easy . Only in the second unit of the “electric field strength”
