物理课后习题有着巩固物理知识,提高学生解决物理问题能力的作用。在教学过程中也会选择一些适合学生学习和发展的物理习题作为学生的练习,以此作为课后学习信息的“反馈”。课后习题对学生错误认识的“矫正”有着十分重要的作用,选择恰当的课后习题也成为日常教学过程中的重要工作。学生通过课后习题既可巩固所学内容,又能发现自身学习的错误和误区,最后再通过教师分析和 Physical exercises after the exercises have to consolidate the physical knowledge, improve the ability of students to solve the problem of physical problems. During the teaching process, some physics exercises suitable for students’ learning and development will also be selected as exercises for students to use as “feedback” for after-school learning information. After-school exercises have a very important role in “correction ” of students’ misunderstanding. Choosing the appropriate after-school exercises has also become an important task in daily teaching.
