First, improving class efficiency is the key. During the study period, the efficiency of class determines the learning effect. We should pay attention to the following aspects to improve the efficiency of attending classes: 1. Preview before class can improve the pertinence of lectures. The problems found in the preview are the focus of the class; You can make up the old knowledge that you haven't mastered well in the preview, which will reduce the difficulties in the process of attending classes and help improve your thinking ability; Preview can also cultivate your self-study ability. 2. Pay attention. Concentration is to devote yourself to classroom learning, from ear to ear, from eye to heart, from mouth to hand. Ear listening: it means listening attentively, listening to how the teacher lectures, how to analyze and how to summarize. Eye-catching: while listening to the lecture, read textbooks and blackboard books, and watch the teacher demonstrate the expressions, gestures and actions of the experiment. Heart orientation: that is, think with your heart and keep consistent with the teacher's teaching ideas. Mouth-to-mouth: refers to taking the initiative to answer questions or participate in discussions. Reaching out: I write down the main points of the lecture and my feelings on the basis of listening, watching, thinking and speaking. 3, take notes, notes are not records, but a simple and clear record of the main points in the above lectures for review. Second, review in time. Review is not to read books or notes over and over again, but to do a retrospective review: first recall what the teacher said in class, then open the notes and books and compare the contents that were not clearly recorded, so as to consolidate the contents of the day, and at the same time check the effect of listening on the same day, and also put forward necessary improvement measures for improving listening methods and improving listening effect. Third, finish your homework carefully. Many students pin their hopes of improving their math scores on doing a lot of problems, which is inappropriate. The important thing is not to do more questions, but to do them well and efficiently. We need to do some exercises on the basis of accurately mastering the basic knowledge and methods. In addition, we should pay attention to the efficiency of doing the problem, that is, how much we have gained after doing it. This requires some "reflection" after doing the problem, thinking about the basic knowledge used in this problem, what is the mathematical thinking method, whether there are other solutions, and whether the analytical methods and solutions of this problem are used in other problem solving. If you connect them, you will gain more experience, and more importantly, develop good thinking habits, which will be of great benefit to the future. Of course, it is impossible to form skills without certain practice, and it is also impossible. Fourth, cultivate self-study ability. If you don't learn by yourself and don't rely on reading comprehension, you will lose a solution to the problem. In addition, science is constantly developing, exams are constantly reforming, and the development of math problems is also constantly diversified. In recent years, applied questions, exploratory questions and open questions have been put forward one after another. Only by self-study can students deeply understand and innovate and adapt to the development of modern science. Fifth, establish a good habit of learning mathematics. Habit is a stable and lasting conditioned reflex and a natural need consolidated through repeated practice. Establishing a good habit of learning mathematics will make you feel orderly and relaxed in your study. Good habits of mathematics should be: ask more questions, think hard, be practical, sum up again and pay attention to application. In the process of learning mathematics, students should translate the knowledge taught by teachers into their own unique language and keep it in their minds forever. In addition, we should ensure that there is a certain amount of self-study time every day, so as to broaden our knowledge and cultivate our ability to learn again. In addition, we should put the accuracy and routine of solving problems in the first place, rather than blindly pursuing speed or skills, which is also an important issue to learn mathematics well. Cultivate a good interest in learning. More than 2,000 years ago, Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy." It means that it is better to love something than to do it, to know it, to understand it, and to enjoy it than to like it. "Good" and "happy" mean willing to learn and enjoying learning, which is interest. Interest is the best teacher. Only when you are interested can you have hobbies. If you like it, you have to practice and enjoy it. With interest, we can form the initiative and enthusiasm of learning. Then confidence will be enhanced and it will be natural to learn math well.
