Want information is anti-spicy. Some people compare the mathematical process to the process of information transmission. Although this view holds that the learning process is too mechanized and equates the complex thinking activities of the human brain with the storage of goods in the warehouse, there are also similarities. Teachers send teachers' information to students, and there are many feedback channels, such as classroom questions, in-class exercises, homework, unit tests, paper analysis and so on. The first two kinds of feedback are the fastest, the third one is 12 days, and the last one should be about a week. For example, a math exam dragged on for ten and a half months, and the students had forgotten the test questions, and the excitement generated during the exam turned into inhibition. It is much more difficult to rekindle students' enthusiasm for learning, and then the effect is bound to be poor.

2. Bilateral activities between teachers and students. Mathematics activity is a bilateral activity between teachers and students. As an educator said, teachers' teaching activities and educational activities are equal to zero without causing students' positive response. In the teaching process of test paper analysis, if only the teacher makes it clear, it is impossible to stimulate the enthusiasm of students to answer questions. The result can only be that the teacher is very tired and the students passively accept it, as if listening to a new lesson, and the effect can be imagined. Teachers must communicate with students emotionally and make a sound in their hearts, so that teachers and students can be in a harmonious bilateral movement.

3. Be sure to draw inferences. A clever teacher not only teaches knowledge, but also needs to train students' problem-solving ideas and general methods, that is, to draw inferences from others. Examination paper analysis should pay attention to the connection, vertical and horizontal comparison, extension and expansion of knowledge. As long as teachers are diligent in summing up some similar knowledge, differences and connections, the effect of test paper analysis will go beyond the test paper itself.

4. Encourage more compliments. Pupils are between 6- 13 years old, and their emotions, will, personality and outlook on life are all in the process of formation and development. More encouragement, more praise and more persuasion are much better than more accusations, criticisms and restrictions. If the students are still lifeless and unhappy after the analysis class, it is undoubtedly a failed test paper analysis class.

5. Score appropriately. This is consistent with the encouragement principle in the last article. Usually, the initiative of exam results is entirely in the hands of teachers. If the score is too high, students will have the illusion that they are eager to learn mathematics. Too low a score is even worse. Students will think that they can't learn math well anyway, and they have no energy and no expectation. The author has held a small forum on this issue, and some students hope that the score will be gradually improved; Some people want to match high and low. Once they failed in the exam, they will have a consolation match next time. What the author knows is that there are many people in the middle, that is, 100 points, 90 points, 60 points and 50 points, and 80 points and 70 points.
