摘要
静电场是电磁学中非常重要的内容.从实际教学中发现,学生对电容率的物理意义的理解比较模糊,影响了静电场尤其是电介质部分的学习质量.这个问题可以通过紧扣ε的物理意义,前后呼应,统整教学设计来解决.
Electrostatic field is an important part of electromagnetism. It is found in classroom that the understanding of permittivity impair the quality of electrostatic field learning especially dielectric learning. The problem can be solved if we pay more attention to the concept of permittivity and redesign the instruction of electromagnetism.
