教材分析:从整个电学系统来看,静电是电学的基础知识。由于静电知识比较抽象,所以难点是:摩擦起电的原因,用静电知识解释简单的静电现象。为此教师必须做到做好静电试验,搞好电学入门教学,应该重视以下几点:(1)创设物理情景,培养学生学习兴趣;(2)设计演示程序,突破教学难点;(3)创造条件,注重素质教育,培养学生的观察能力和创造能力。 Textbook analysis: From the perspective of the entire electrical system, static electricity is the basic knowledge. As the static electricity is rather abstract, so the difficulty is: the reason of triboelectric charging, static electricity to explain the simple phenomenon of static electricity. To do this, teachers must do static electricity experiments and do a good job of teaching electric introductions. The following points should be emphasized: (1) to create physical scenarios to cultivate students’ interest in learning; (2) to design and demonstrate programs to break the teaching difficulties; (3) to create Conditions, focus on quality education, develop students’ observation and creativity.
