许多教学实践证明:一个学生做过的练习时间超过一个学期或是一年,很少人再去复习、巩固。但是在做过的这些练习中,有许多在以后的学习中会衔接用到的习题,也有很多类似的习题在以后会犯同样的错误。要想尽可能减少失误,必须找到补漏的好办法,而建立错题集就是我们数学学习中查漏补缺的绝佳助手。在数学学习中,无论是练习还是考试,大部分学生对于自己做错的题,经过教师讲解之后,都会觉得自己不应该出现错误。可是,下一次考试仍然会重复过去的 Many teaching practices prove that a student has practiced for more than one semester or one year, and few people go to review and consolidate. However, many of the exercises that have been done converge to the exercises used in later studies, and many similar exercises make the same mistakes later on. In order to minimize mistakes, we must find a good way to trap, and the establishment of the wrong title set is a perfect assistant in our mathematics learning. In maths learning, whether it is practice or examination, most students make mistakes about themselves, and after the teachers explain, they think they should not make mistakes. However, the next exam will still be repeated in the past
