习题课不应是简单地做几道类型题,习题课应有“主题”。我们感到习题课的教学目的应突出三个方面:1.使学生准确、灵活地掌握物理知识,扩大知识的联系。2.使学生建立分析和求解物理题的思路和方法。3.习题课是发展学生思维能力的重要环境,因此要改革习题课的教学方法,以利于培养学生的思维能力和思维习惯。当然不是每节课都能等量地达到这三个目的,具体课节往往是有所侧重。下面以具体的一节习题课为例进行探讨。在学完《机械能》和《动量》两章之后,为了培养和锻炼学生综合应用所学力学知识的能力,开了一节主题为“多过程力学综合题分析”
Practice classes should not be simply a few types of questions, and problem classes should have “topics”. We feel that the teaching purpose of the exercises should focus on three aspects: 1. To enable students to acquire physical knowledge accurately and flexibly, and to expand the connection of knowledge. 2. Enable students to establish ideas and methods for analyzing and solving physical problems. 3. Exercise class is an important environment for the development of students’ thinking ability. Therefore, we must reform the teaching methods of the exercises to help students develop their thinking ability and thinking habits. Of course not every class can achieve these three goals in equal amounts. The specific lessons are often focused. The following takes a specific one-step exercise class as an example. After finishing the two chapters of “Mechanical Energy” and “Momentum”, in order to cultivate and train students’ ability to comprehensively apply the learned knowledge of mechanics, he opened a section entitled “Analysis of Synthesis Problems of Multi-Process Mechanics”.
