物理教学中,较普遍存在的问题之一:学生在课堂上听懂了,课后不会做题.这实际上是学生的解题能力问题.造成这一现象的原因是多方面的.有的是因为教师在备课时教材的系统性、科学性未能深入挖掘,因而在课堂上只能作片断的讲解,学生也就不能接受全部的课程内容,东鳞西爪、一知半解地学到一些零碎知识,于是课后作题就发生困难的;有的是因为给学生所留的作业,不能与教材有机的配合,使得学生作题时无从下手;有的是由于过份强调独立作业,使得学生有问题不敢问,这样日积月累使得学生在完成作业上有了困难;有的是因为学生不懂得先掌握理论知识,然后处理习题的学习方法;有的是因为学生在解题时,不能抓住问题的关键,就盲目动手去解习题.这样学生在完 In physics teaching, one of the more common problems is that students understand in class and do not do questions after class. This is actually the problem-solving ability of students. There are many reasons for this phenomenon. Some are Because the teacher’s systemic and scientific teaching materials cannot be digging in depth during class preparation, students can only make lectures in class. Students can’t accept all the course contents. They learn a little piecemeal knowledge from the eastern scales and western claws. Therefore, problems occur after the class; some of them are because the assignments for students cannot be organically coordinated with the teaching materials, making it impossible for students to start their own problems; others are overemphasizing independent assignments, making students have problems and dare not to ask questions. This accumulates and makes students have difficulties in completing their homework; some are because students do not know how to master the theoretical knowledge first, and then deal with the study methods of the exercises; some are because the students cannot grasp the key of the problem when they solve the problem, and then go blindly to solve the problem. This way the students are finished
