Give you some opinions and suggestions: First, we should change our ideas and improve our interest in learning mathematics. Interest and confidence are the best teachers to learn math well. If your interest improves, you will fall in love with learning math. If you love learning math, your grades will naturally improve. The "interest" mentioned here does not mean studying mathematics and becoming a mathematician in the future. But it mainly means not being tired of mathematics and not being a burden. There is a saying: "Great motivation comes from great ideals". As long as you understand the importance of learning mathematics, you will have unlimited motivation and gradually become interested in mathematics. With a certain interest, your confidence will be enhanced, and you won't be discouraged because of an unsatisfactory exam result. In the process of constantly summing up experience and lessons, your confidence will continue to increase, and you will increasingly realize that "interest" and confidence are the best teachers in your study. Second, improving the efficiency of class is the key. During the study period, class time accounts for a large part. So the efficiency of class determines the basic situation of learning. We should pay attention to the following aspects to improve the efficiency of class attendance: 1, and preview before class can improve the pertinence of class attendance. The difficulty found in the preview is the focus of the lecture; You can make up the old knowledge that you don't have a good grasp in the preview, which can reduce the difficulties in the process of attending classes; Preview helps to improve thinking ability. After previewing, you can improve your thinking level by comparing and analyzing what you understand with the teacher's explanation. Preview can also cultivate your self-study ability. 2. Science in the process of listening to lectures. First of all, we should make good material preparation and ideological preparation before class. So that books and books will not be left behind in class; The second is to concentrate on class. Concentration is to devote yourself to classroom learning, from ear to ear, from eye to heart, from mouth to hand. Listen to the teacher attentively, how to teach, how to analyze and how to summarize. In addition, listen to the students' questions and answers to see if they are enlightening. Eye-catching: it means that while listening to the class, we should carefully read the textbook and the teacher's blackboard, as well as the teacher's expressions, gestures and demonstrations, and so on, and accept the ideas that the teacher wants to express vividly and profoundly. Heart to heart: Just think hard, keep up with the teacher's mathematical thinking, analyze how the teacher grasps the key points to solve the problem, and try to think like that myself. Mouth-to-mouth: refers to taking the initiative to answer questions or participate in discussions under the guidance of teachers. Reaching out: It refers to taking out the key points of this chapter (section) on the basis of listening, watching, thinking and speaking, and writing down the main points of the lecture and your own feelings or opinions with innovative thinking. If you can achieve the above five goals, your energy will be highly concentrated, and all the important contents learned in class will leave a deep impression on your mind. Pay special attention to the beginning and end of the teacher's lecture. Before speaking a new lesson, the teacher usually summarizes the main points of the last lesson and points out the content to be talked about in this lesson. This is the connection between old and new knowledge. Teachers often sum up the knowledge of a lesson at the end, which is very general. This is the outline of mastering the knowledge and methods in this section on the basis of understanding. 4. We should carefully grasp the logic of thinking, master the thinking of analyzing problems and the thinking method of solving problems. As long as you insist on doing this, you will be able to draw inferences from others and improve your thinking and problem-solving ability. In addition, we should pay special attention to the hints in the teacher's lecture. For some key and difficult points in lectures, teachers often give hints about language, tone and even some actions. Everyone must pay special attention to this. The last point is to take notes. Notes are not records, but simple and concise records of the main points and thinking methods in the above lectures for review, digestion and thinking. Third, do a good job in reviewing and summarizing. 1, review in time. On the second day after class, you must do a good job of reviewing that day. The effective review method is not to read books or take notes over and over again, but to review through recollection: first, put the books and notes together, and recall the definitions, examples, ideas and methods of analyzing problems that the teacher said in class (you can also write them in a draft book while thinking). Try to think completely, then open your notes and books and compare what you haven't remembered clearly. If you haven't mastered something, fill it up. In this way, the content of the class on the same day was consolidated, and the effect of the class on the same day was also checked. The necessary improvement measures were put forward, and the listening methods and effects were improved. 2. Do a good unit review. After learning a unit, you should review it in stages, and the review method is the same as timely review. We should review retrospectively, and then compare it with books and notes to make its content perfect, and then do a good job of unit plate. 3. Make a unit summary. The unit summary shall include the following parts. (1) Knowledge structure of this unit (chapter); (2) The basic ideas and methods of this chapter (which should be expressed in the form of typical cases); (3) Self-experience: In this chapter, you should record the typical problems you made wrong, analyze their causes and correct answers, and record the thinking methods or examples you think are the most valuable in this chapter, as well as the problems you haven't solved, so as to make up for them in the future. Fourth, on the problem of doing problems, many students pin their hopes of improving their math scores on doing a lot of problems. This is inappropriate. A mathematician once said, "Don't judge a hero by the number of problems you solve." In learning mathematics, the important thing is not to do more problems, but to do them efficiently. The purpose of doing the problem is to check whether you have mastered the knowledge and methods you have learned well. If you don't master it correctly, or even have deviations, then the result of doing so many questions is to consolidate your own shortcomings, which can be described as "doing the opposite"! So we should do some exercises on the basis of accurately mastering the basic knowledge and methods. Especially for topics with moderate difficulty, we should pay attention to the benefits. No matter how much you gain after doing the problem, you need to do some "reflection" after doing it and think about the basic knowledge used in this problem. What is mathematical thinking method? Why do you think so? Are there any other ideas and solutions? Have the analytical methods and solutions of this problem been used to solve other problems? Only by connecting them in this way can you gain more experience and lessons, and more importantly, you will form good thinking habits, which will be of great benefit to your future study. Of course, it is impossible to form skills without a certain amount of practice (homework assigned by the teacher), and it is also impossible. It is absolutely impossible not to do the problem! ! In addition, whether it is homework or exam, we should put accuracy first, and put the methods and ideas of bud solution first, instead of blindly pursuing speed or skills. Learning mathematics well is also an important issue.
