在高中物理课堂教学中,习题课主要有两方面功能:一是巩固概念、规律,及时了解教学情况,进而构建知识结构。通过习题课可以帮助学生对已经学习过的知识进行梳理、辨析和应用,达到对知识的巩固和提高,帮助学生形成知识网络和结构,从而加深对知识的理解及知识之间内在联系的把握。二是深化知识、培养学生的思维品质,提高解题能力。而提高习题课的效率,要遵循以下几个原则。 In high school physics classroom teaching, the exercises class has two main functions: First, to consolidate the concepts and laws, keep abreast of the teaching situation, and then build the knowledge structure. Exercises can help students to sort out the knowledge already learned, discrimination and application, to consolidate and enhance knowledge, to help students form a knowledge network and structure, so as to deepen the understanding of knowledge and knowledge of the inner link between the grasp. The second is to deepen knowledge, develop students’ thinking quality, improve problem solving ability. To improve the efficiency of exercise class, we must follow the following principles.
