在几年的教学过程中,笔者经常碰到这样的情况:课堂上反复讲过多次的题目,练习中也做过多次的题目学生仍然掌握得不好,或者根本就没有印象。也经常听学生说,上课我都听懂了,可自己就是不会做。究其原因,主要是学习缺乏主动性,被动学习,以及学生的学习方法有待改进,学习效率不高所致。 In a few years of teaching process, I often encounter such a situation: the class repeated many times the subject, the practice has also been done many times the subject is still not well-controlled students, or simply no impression. Listen to the students often, I have learned in class, can not do it myself. The reason is mainly lack of initiative to learn, passive learning, as well as student learning methods need to be improved, learning efficiency is not high.
