苏科版初中物理九年级教材绝大多数的内容是电学部分。在学生生活实践中,天天看到电现象,享受着电能给我们生活带来的便利和舒适。但很少有学生去研究电路是怎么连接的,电能是怎样从发电厂送到千家万户的。学生对于电学的知识只能从有限的物理课堂中去获取。由于缺少感性的认识,建立不了电路模型,对于运用课本知识解决电路问题就显得非常困难。从初三的物理 Suke version of junior high school physics ninth grade teaching most of the content is the electrical part. In the student life practice, every day sees the electricity phenomenon, enjoys the convenience and the comfortable which the electric energy brings to our life. But few students study how the circuit is connected and how the power is delivered from power plants to millions of households. Students’ knowledge of electricity can only be obtained from a limited number of physical classes. Due to the lack of perceptual knowledge, can not establish the circuit model, the use of textbook knowledge to solve circuit problems is very difficult. From the third day of physics
