单元复习课如何上好,这是大家都在探讨的课题。近几年来,我通过实践,深感要提高复习课效益,课堂结构设计是颇为重要的一环。针对青少年思维活动的特点,用“设疑、析疑、答疑”的方法,由浅入深、由表及里、举一反三、巧拟问题,启发学生用脑、动手,确能收到事半功倍的成效。现就初三物理《电功、电功率》这一单元的一堂复习课,谈谈自己的做法与体会。按物理教学大纲规定,这一单元的教学目的是:掌握电功、电功率的物理意义、公式和单位,掌握没定电功率的方法;解决有关简单的 How the unit review class is good is a topic that everyone is discussing. In recent years, through practice, I have felt deeply that we must improve the efficiency of review classes. The design of classroom structure is an important part. According to the characteristics of young people’s thinking activities, using the method of “problem, doubt, and suspicion”, from the shallow to the deep, from the surface to the inside, from the surface to the inside, and from the top to the bottom, the problem is ingeniously solved. This will inspire the students to use their brains and hands, and they can really get twice the result with half the effort. . Now I will talk about my practice and experience in a review class for the third year of the physical “electric power, electric power” unit. According to the syllabus for physics syllabics, the purpose of this unit is to grasp the physical meanings, formulae, and units of electrical power and electrical power, and to grasp the method of not determining the electrical power;
