There are three kinds of common "wrong question sets": one is to modify, that is, to copy down all wrong questions and modify them; The second type is summary, which classifies all wrong questions according to the order of textbook chapters; The third type is error correction, that is, all the wrong questions are sorted according to the reasons for the mistakes.

This paper introduces a new type of "wrong question set"-loose-leaf wrong question set, and its sorting steps are as follows:

1 sort. Classify and sort out all the wrong questions, and distinguish the reasons for the mistakes: vague concepts, carelessness, attention to one thing, charts, skills, new concepts, mathematical ideas, etc. , and indicate that each question belongs to a chapter. The advantage of this classification is that it can not only find the causes of errors, but also find the knowledge points that are prone to errors in each chapter, which brings convenience to future review and simplifies the "wrong problem set" when sorting out.

2 recording method. Teachers should pay attention to the teacher's analysis and explanation of wrong questions, the introduction of questions, the breakthrough point of solving problems, the breakthrough method of thinking, the skills of solving problems, the steps and summary of standardization, etc. Annotate on the wrong side, write down your thinking process when solving problems, and expose the reasons and root causes of your thinking obstacles. This narrative may be difficult or impossible to write at first, so don't force yourself. In the initial stage, you can write a summary in your own language. If you sum up a lot, you will naturally gain experience and gradually realize the various obstacles of thinking (that is, the reasons for mistakes).

3 necessary supplements. The work ahead is just the beginning, and the most important work is yet to come. It doesn't necessarily mean that the wrong questions in the "wrong question set" have been revised perfectly, which proves that the loopholes in your knowledge have been filled. For each wrong question, you must also check the materials or textbooks to find out the same or related questions and make an answer. If there is no difficulty, it means that you may have mastered this knowledge point. If it still can't be solved, it is necessary to further deepen the handling of this problem. Because in the next test, you may make the same mistake on this question.

4 wrong topic adaptation. This work is difficult, and students with rich experience in solving problems may finish it smoothly. Because every question is compiled by the teacher, since the teacher can compile it, of course, as students, we should learn how to correct it, which is the best way to bridge the knowledge gap. In the initial stage, students only need to make a little change in the subject conditions.
