One. The purpose of establishing "wrong problem set" is to cultivate students' study habits and learning quality. Insist that every student concentrate the wrong excerpts from daily exercises such as homework and exams, and post them if there are any mistakes. At this time, it is necessary to clarify the purpose and encourage students. I tell students that the purpose of sorting out the "wrong question set" is to cultivate good study habits and reduce wrong questions. At first, I felt as if I had added trouble and increased my study burden. In fact, you can reduce your troubles in the future, urge yourself to study hard, do your homework seriously, and make fewer mistakes or even no mistakes. However, some students with poor study habits and grades are afraid that there will be many wrong questions in their homework, which will lead to ideological conflicts and difficulties in implementation. Although I regard it as a good opportunity to correct their learning attitude and cultivate good habits. With a clear purpose and knowing the benefits, students' consciousness has been improved. After a period of time, students can use the set of wrong questions to classify, simplify and extrapolate, copy down all the wrong questions that the teacher doesn't know, and correct and analyze them well. Second, we should grasp the requirements of establishing "wrong problem set" and persevere. When reading "wrong questions set", I always carefully analyze the characteristics of each student's wrong questions and guide the cultivation of habits. At the beginning, focus on every day, strictly supervise as required, rest first when you finish first, and extend the time appropriately if there are many wrong questions. Guiding methods, training thinking. It not only inspires students to understand the requirements of the topic, but also guides students to learn how to analyze the wrong topic, requires students to read the specific process and key points of solving the wrong topic carefully, and helps students learn to reflect on the process, understand the problem through reflection, and learn to learn. It trains students to think methodically and overcomes the confusion of thinking. After a period of time, students gradually gave up the psychology of not doing it by luck and formed a habit. At this time, I still seize the opportunity to educate students to listen carefully in class, ask if they don't understand, leave no doubt, and try to avoid or make fewer mistakes. Every student's wrong questions in various situations are concentrated on the wrong set according to their true colors, which is equivalent to establishing a ledger, and teachers and students have accurate review basis. Usually, when instructing students to modify the analysis, they should collect the same type of errors, find out the reasons of * * * *, and take corresponding corrective and remedial measures. In unit, mid-term and final review, guide students to comprehensively classify wrong questions. First, classify according to content, so as to systematize knowledge. Second, according to the classification of questions, simplify the complex and focus on the goal; Third, according to the classification of the wrong reasons, we can draw inferences from one instance and get twice the result with half the effort. In this way, students can better master the method, reduce the burden, improve the effect, and realize the superiority of the wrong problem set. Third, the step of sorting out the "wrong question set" (1) classifies all the wrong questions, distinguishes the reasons for the mistakes, and indicates that each question belongs to a certain chapter or section. The advantage of this classification is that it can be found through the error reasons and the knowledge points that are easy to make mistakes in each chapter, which will bring convenience to future review. In addition, the "wrong question set" is simplified. When sorting out the same type of questions, you can only record typical questions, and you may not find every wrong question. (II) Recording Methods When reviewing the examination papers, teachers should pay attention to the analysis and explanation of the wrong questions, annotate the wrong questions, write their own thinking process when solving problems, and expose the analysis of the reasons and roots of their thinking obstacles. If you sum up more, you will naturally have experience and gradually understand the obstacles of thinking. (3) Necessary supplements 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) Learn from each other. A good set of "wrong questions" is the inscription of one's own knowledge loopholes. Usually, we should pay attention to sorting out and summarizing in time. In math review, "wrong problem set" is your most important review material, so you should review it frequently. "Read a book a hundred times, and its meaning is self-evident", thus giving inferences. Although each student's "wrong problem set" is different, the advantages of other students' "wrong problem set" can be used for reference, so students should also pay attention to communicate with each other at ordinary times. Fourth, the role of teachers in sorting out "wrong problem sets" As far as teachers are concerned, after a long time, they can analyze the problem tendencies of different students and the whole teaching, which is convenient for grasping the key points and discovering the rules, overcoming the phenomenon of grasping blindly in the past review, improving the pertinence of review remedy and greatly improving the enthusiasm of students. Students' mistakes are difficulties in their study. Based on this, I not only designed the review questions, but also abandoned the sea tactics to reduce the burden on students. Therefore, the teaching ideas are clearer, the pace of teaching reform is more solid, and students themselves know how to focus on tackling key problems, remedy, reflect, make progress and innovate according to the wrong questions, and all aspects complement each other. Teachers' correcting homework is an important part of teaching. The problem of "batch-by-batch revision" takes too much time, especially for correcting geometry homework. Students are completely passive, and the information obtained by both teachers and students is very distorted. Then the following methods can be adopted: correcting homework in class, correcting homework in groups, checking and approving by teachers, and exchanging information in time by information groups. Through the above points, students become passive and teachers become monologues and directors, giving full play to the enthusiasm of both teaching and learning. 5. The achievement of "Wrong Question Set" (1) enhances students' reflective consciousness and promotes the formation of students' study habits. 1. Students have the habit of reflecting on homework mistakes. 2. Students can analyze problems from the perspective of development. 3. Cultivate students' learning quality (2) Improve students' autonomous learning ability and promote students to "learn to learn". The cooperation between teaching and learning creates a scientific humanistic environment, pays attention to cultivating students' independent thinking and autonomous learning ability in the process of mathematics, and shifts the focus of teaching and learning from acquiring knowledge to "learning to learn" and mastering learning methods. Practice has proved that students can modify and adjust their learning strategies according to the changing learning situation in reflection, which improves learning efficiency.
