一、问题的提出初中物理中的概念多为物理学中最基本的概念,而这些概念一般是从大量的物理现象中总结出来的,由于初中生抽象思维能力不强,要独立地形成正确的物理概念有些困难。如静电学的初步知识,学生对摩擦起电的现象比较熟悉,但对摩擦起电的原因——电子的得失难以理解,其原因是电荷太小,学生没有看见。由于对电荷概念难以接受,导致对 First, the problem raised Middle school physics concepts are mostly the most basic concepts in physics, and these concepts are generally summarized from a large number of physical phenomena, as junior high school students abstract thinking ability is not strong, to independently form the correct The physical concept is somewhat difficult. Such as the initial knowledge of electrostatic, students are familiar with the phenomenon of triboelectric charge, but the cause of triboelectric friction - the electronic gain difficult to understand, because the charge is too small, the students did not see. Due to the unacceptable concept of charge, it leads to right
