高中物理现行教材对静电平衡问题只作了概括论述,大多数老师在教学中也只对静电平衡状态下导体的性质作结论性的罗列,缺少对相关问题的深入思考,甚至对学生提出的深层问题采取敷衍的态度,不利于学生思维能力的提高及学科兴趣的培养。本文选取静电平衡知识的几个侧面进行讨论,涉及的都是与高中学习有关而且容易忽视的,或者高中阶段感到困惑的问题,以求对中学老师的备课有所帮助,进而使学有所长的学生有所收益。
The current textbook for high school physics only gives a general overview of the issue of electrostatic balance. Most teachers in teaching only make a conclusive list of the nature of conductors in electrostatic equilibrium, lacking in-depth consideration of relevant issues, and even deeper questions for students. The perfunctory attitude is not conducive to the improvement of students’ thinking ability and the cultivation of subject interests. This article selects several aspects of electrostatic balance knowledge and discusses issues that are related to high school learning and are easily overlooked, or that are confusing during high school, in order to help middle school teachers prepare for the lesson, and then to make learning Students benefit.
