“静电平衡”是高中物理中的一个教学难点.笔者在连续十几年的高三物理教学中发现,学生对这部分内容的学习普遍表现为:特点记得很熟,但理解不透,具体运用时会出错.如何在教学中从根本上突破这一难点,使学生全面、正确地理解静电平衡的特点,现介绍笔者在这方面所探索出的教学方法,供参考. “Electrostatic balance” is a teaching difficulty in high school physics. The author found that in the third consecutive physics teaching for more than ten years, students generally expressed this part of the contents of the study: the characteristics are well-remembered, but not understandable, when used specifically There will be mistakes. How to fundamentally break through this difficulty in teaching, so that students fully and correctly understand the characteristics of electrostatic balance, now introduce the author in this regard explored teaching methods for reference.
