I carefully read the students' papers and found a common phenomenon: students are still prone to make mistakes in some topics they do. Ask the students carefully, some of them didn't digest it in time, and the other part was careless, so that they lost a lot of points in the exam. Faced with this phenomenon, I suggest that they adopt the wrong problem set. The "wrong title book" refers to that students organize the wrong questions in their homework, exercises and test papers into a book in the learning process, which is convenient for finding the weak links in their own learning, making the learning focus more prominent and learning more targeted, thus improving learning efficiency and academic performance.

The "wrong question book" can change students' attitude towards mistakes, and the attitude towards wrong questions is the key to reduce them. Mistakes are precious, because mistakes can make students realize their own shortcomings, and they can't be ignored because there are few wrong questions or simple reasons. A mistake is actually a blind spot. If you don't take a positive attitude towards mistakes, or lack an ideal way to solve them, mistakes will happen at any time, and often happen repeatedly. We must treat mistakes "kindly" and "strictly". "Wrong title book" can get rid of the bad habit of carelessness. Students do their homework seriously for fear of copying wrong questions or losing face because of too many wrong questions, and they are no longer so-so.

If the wrong problem set is established, how to use it?

(1) Read frequently. Most mistakes are made because of the lack of solid knowledge, so we should often "encounter" when dealing with mistakes, just like the problem of "1+ 1=2", and we will not make mistakes even in our dreams. Especially before the exam, students are advised to take it and watch it to prevent it from happening again.

2 communicate with each other. Students exchange "wrong books", learn from each other, inspire each other, and look for "gold" in "wrong questions" in order to improve together.

③ Extended functions. It is suggested that several functions should be improved on the "wrong question book", just like modules, so as to make the "wrong" clear, such as: marking the wrong reasons such as "conceptual error", "thinking error", "understanding error" and "examination error"; Mark "wrong knowledge points, etc." ; Write the methods and skills of answering questions.

④ Persistence is the key to the use of the wrong book, and only persistence can be effective.

In the process of using the wrong problem book, some students not only sort out the wrong problems themselves, but also sort out the "easy-to-mistake problems", "difficult problems", "typical problems" and "good problems" together, which is called "good problem book"
