做练习是高中物理课堂教学的重要环节。学生将所学的书本知识运用于实际大部分是通过习题训练完成的。做练习既可使学生获得新的技能,还可以促进学生对已有知识的理解巩固和深化,为教师提供反馈信息的重要依据。如何才能强化练习环节呢?笔者认为主要从以下几个方面入手。一、精心设计练习题教师必须精心设计练习题,做到突出重点,层次分明。设计高 Exercises are an important part of high school physics teaching. Most students apply the book knowledge they have learned to practice through exercises. Do exercises can not only enable students to acquire new skills, but also to promote students to consolidate and deepen the understanding of existing knowledge, provide an important basis for teachers to provide feedback. How can we strengthen the practice session? I think the main aspects from the following aspects. First, well-designed exercises Teachers must carefully design exercises, to highlight the key points, structured. High design
