1, the design dimension collects the corresponding wrong questions and arranges them into a book. A subject should not have only one wrong book. Of course, it doesn't matter if there is a detailed dimension to distinguish the wrong book. What does dimension mean? It refers to an independent parameter, that is, you can sort out related wrong questions according to this parameter, and then find its law to help.

2. Wrong questions need to be judged first and then sorted out. Not all wrong questions need to be collected. After designing the dimensions and preparing the corresponding wrong problem books, not all the wrong problems are suitable for collection when students sort out the wrong problems.

How to sort out the wrong problems in mathematics saves time and effort;

It is best to press the time, followed by the wrong frequency. You should change the revised edition regularly, because it needs to be used. It will be updated when it is finished. If it is wrong, continue to add the wrong version, otherwise delete it, which can simplify the version, save time and improve efficiency.

The following practices:

1. Prepare a thick notebook, which is the wrong book. Don't buy fancy ones in the market, just use a notebook, just a little thicker.

2. When encountering a wrong problem, write it in the wrong problem book, the stem of the problem and the solution of the wrong problem are written in black, the relevant fuzzy formula knowledge is written in red+positive solution process, and the key places are specially marked.

3. After learning a chapter, come to a wrong topic summary meeting to see which pits you will fall into in this chapter, and form a framed wrong topic summary to avoid in the future.

4. Show your wrong problem book to the math teacher and let the teacher show you the way from the side. It depends on the master.

5. Sort out the wrong questions in the test paper separately, use post-it notes with different colors to help classify, analyze the results and reasons for gains and losses, and sort out the wrong questions in a separate folder. If it is a little troublesome to cut the test papers, compile them separately, especially when there are many test papers in junior and senior high schools. This is more practical.

It is a very good method and habit to sort out the wrong questions in science, especially mathematics. Let's talk about several sorting methods of wrong questions:

1. Students who don't have many wrong questions and have time should copy them down and do them again, which is generally suitable for once a week. Remember to keep a copy for the second wrong exercise.

2. Shooting printing method is suitable for students who have printers with wrong questions at home, which is convenient, fast and costly.

3. Cut and paste directly on the wrong question book, which is suitable for non-double-sided wrong questions. Cut and paste directly in the wrong book, and then practice the wrong questions in the blank.

4. Nail the test papers and exercises with wrong questions directly, and only read the wrong questions at a time, which is the most time-saving, but it is not convenient for centralized viewing. We should use the wrong book to analyze the types of wrong questions, find the weak points, causes and solutions of wrong questions, and truly achieve the purpose of sorting out wrong questions.
