高中物理必修本对“电场”一章进行删减，从而减轻了学生的学习负担．但学生在理解必修本中的电场强度、电场线、电势差和电容等抽象概念时仍有不少困难．为有效突破教学难点，我在平时教学中，着力做好以下几点：一、提高演示实验的效果“电场”一章的抽象概念，如果教师... High school physics required revision of the “Electric Field” chapter, thereby reducing the student’s learning burden. However, students still have difficulties in understanding the abstract concepts of electric field strength, electric field lines, potential differences, and capacitance in the compulsory books. In order to effectively break through the teaching difficulties, I do my best to do the following in the usual teaching: First, to improve the effect of the demonstration experiment The abstract concept of the “Electrical” chapter, if the teacher...
