The wise man described mathematics as "gymnastics of thinking, sparks of wisdom". The science or discipline that can best test or verify how much wisdom a person has! In today's era of knowledge economy, mathematics is moving from behind the scenes to the front. Its combination with computer technology has directly created various values for the society and promoted the development of social productive forces. Mathematics is one of the important components of human culture and has become a basic quality that citizens must possess. Mathematics plays a unique and irreplaceable role in the formation of human rational thinking. As a result, many people choose academic theory during the sprint of the college entrance examination, and many people swear to use mathematics to pull the total score of the college entrance examination. Congratulations! Mathematics as an important subject to measure a person's ability. From primary school to high school, many people have a special liking for it, and most of them have invested a lot of time and energy. However, we can't ignore another fact: not everyone is a success! Many excellent students in elementary school and junior high school entered the high school stage and were planted in mathematics in the first autumn. The survey of successful students who choose liberal arts also shows that although they also want to learn high school mathematics well, their math scores can't be improved, which reflects the phenomenon that they are most afraid of meeting high school math teachers. This phenomenon of "fear" of high school mathematics is relatively common at present, which should be paid attention to. Of course, there are many reasons for this phenomenon. This paper only talks about the reasons and solutions that affect the decline of mathematics scores in senior high schools from the students' learning status. In the face of many students who succeed in junior high school mathematics learning becoming losers in senior high school, the author investigates their learning status. The results show that the main reasons for the decline in grades are: 1. passive learning. After entering high school, many students, like junior high school, have a strong dependence: follow the teacher's inertia. There is no initiative in learning. Its manifestations are: uncertain plan, waiting for lectures, not previewing before class, not knowing what class the teacher will take, being busy taking notes in class, and not hearing the "doorway". All these make you unable to really understand what you have learned. You can't learn law. Teachers usually talk about the ins and outs of knowledge, analyze the connotation of concepts, analyze key points and difficulties, and highlight thinking methods. However, some students can't concentrate on the lecture in class, and they can't hear clearly or fully. So I took a big notebook and left a lot of questions. But after class, we can't consolidate and summarize in time, and we can't find the connection between knowledge. They just did their homework in a hurry and confused the questions. A little knowledge of concepts, rules, formulas and theorems, and the result of rote memorization is blind "mechanical imitation". Some people work overtime at night, are listless during the day, or don't listen at all in class, so they do another set. In the end, get twice the result with half the effort You don't pay attention to the foundation. Some students who "feel good about themselves" often despise the study and training of basic knowledge, skills and methods. The consistent practice is to only know how to do it, without careful calculation and writing. Its psychological inducement is only interested in difficult problems to show its "high level". This condescending attitude, which emphasizes "quantity" rather than "quality", has led to a sea of problems. But when it comes to formal homework or exams, it is a calculation error or "stuck" in the middle. 4. There are no conditions for further study. Compared with junior high school mathematics, senior high school mathematics has deeper knowledge and higher ability requirements. This requires you to master basic knowledge and skills. In order to make full preparations for further study, there are many difficulties, new methods and strong analytical abilities in senior high school mathematics, such as the maximum value of quadratic function in closed interval, the solution of function value domain, the distribution of real roots and parameter equation, the deformation and flexible application of trigonometric formula, the formation of spatial concept, the application of permutation and combination, and the solution of practical application problems. Objectively, the ability requirements of these questions are the differentiation points of mathematics learning. What's more, some knowledge points of mathematics are out of touch with the textbooks of high school and junior high school. If remedial measures are not taken, division is inevitable. Therefore, it is not enough for high school students to just want to learn, but also to "learn". We should pay attention to scientific learning strategies and methods, improve learning efficiency and change passive learning into active learning. In view of the above situation in students' study, teachers should take countermeasures: 1. Strengthen study guidance and cultivate good study habits. Good study habits include making plans, self-study before class, paying attention to class, reviewing in time, completing homework independently, solving problems, systematically summarizing and studying after class. (1) Making a study plan can make the study objectives clear and the time arrangement reasonable. In order to be neither too slow nor too slow. Making a study plan is the internal motivation to promote students' active learning and overcome difficulties, but the plan must be practical, with both long-term plans and short-term arrangements. More importantly, we should be strict with ourselves in the implementation process and temper our learning will. (2) Self-study before class is the basis for students to learn new lessons well and achieve better learning results. Self-study before class can not only cultivate self-study ability, but also improve their interest in learning new lessons and master the initiative in learning. Self-study should not go through the motions, but pay attention to quality, try to understand the teaching materials before class and pay attention to the teacher's ideas in class, so as to grasp the key points, break through the difficulties and do our best. On the other hand, we know that the classroom is the key to understand and master the basic knowledge, skills and methods. "Lack of pre-school learning", experience shows that students who have taught themselves before class can concentrate more in class, and they know where to be detailed and where to omit; Where to carve, where to pass by. Write down what you should remember, instead of writing it all down. (3) Review in time. As the ancients said, only by reviewing the past can we know the new. Timely review is a common method to acquire new knowledge and understanding, and it is also an important part of efficient learning. By reading textbooks and consulting relevant materials repeatedly, we can strengthen our understanding and memory of the basic concept knowledge system. At the same time, link the new knowledge with the old knowledge and make an effective analysis. Review is the only process or way to change new knowledge from "understanding" to "knowing". (4) Doing homework independently is a necessary process for students to further deepen their understanding of new knowledge and master new skills through their own independent thinking, flexible analysis and problem solving, and this process is also a test of students' will and perseverance. Through the application, students can complete the process from "knowing" to "being familiar with" what they have learned. (5) Problem-solving refers to the process of exposing the wrong understanding of knowledge or missing the answer because of blocked thinking, and making the ideas flow by enlightening and supplementing the answers. Be persistent when solving problems and do the wrong homework again. Be sure to think again and again until you think clearly about your mistakes, and ask teachers and people who can't really solve them. Digest what you get from asking teachers or classmates for help and turn it into your own knowledge. Long-term persistence will make the knowledge learned "familiar" to "vivid". (6) Systematic summarization is an important link for students to master knowledge comprehensively, systematically and profoundly and to develop their cognitive ability through positive thinking. In summary, on the basis of systematic review, textbooks, notes and related materials, through analysis, synthesis, analogy and generalization, the internal relationship between knowledge is revealed, so as to achieve the purpose of mastering the knowledge learned. We can change what we have learned from "living" to "understanding". (7) Extracurricular learning includes reading extracurricular books and newspapers, participating in academic competitions and lectures, visiting senior students or exchanging learning experiences with teachers. Extracurricular learning is the supplement and continuation of in-class learning, which can not only enrich students' cultural and scientific knowledge, deepen and consolidate what they have learned in class, but also satisfy and develop students' hobbies, cultivate students' awareness of autonomous learning and improve learning efficiency. Stimulate curiosity and enthusiasm for learning. Step by step to prevent impatience. Due to the young age and limited experience of students, a large number of high school students are prone to impatience, and some students are greedy for quick results and swallow dates; Some students want to "sprint" in a few days; Some people are complacent when they get a little success, and will never recover when they encounter setbacks. In view of these situations, teachers should let students know that learning is a long-term accumulation process of consolidating old knowledge and discovering new knowledge, which can never be achieved overnight. High school should last three years instead of three days, which is an example. A very important reason why many excellent students can get good grades is that their basic skills are solid, and their reading, writing and computing abilities have reached the level of automation or semi-automation. 3. Study the characteristics of the subject and find the best learning method. Mathematics is responsible for cultivating students' computing ability, logical thinking ability and spatial imagination ability. And the ability to analyze and solve problems by using what you have learned. It is characterized by high abstraction, strong logic, wide applicability and high requirements for ability. Learning mathematics must pay attention to "living": you can't just read books without doing problems, and you can't bury yourself in doing problems without summarizing and accumulating. We should be able to get in and out of the textbook knowledge and find the best learning method according to our own characteristics. This is the reason why Mr. Hua advocates the learning process of "from thin to thick" and "from thick to thin". The methods vary from person to person, but the four steps of learning (preview, class, arrangement and homework) and one step (review and summary) are indispensable. These places generally have the characteristics of new methods, great difficulty and strong flexibility. For teachers who are prone to division, we should take repeated measures, strengthen counseling, offer special lectures, and guide reading reference books. , and put forward mistakes for students to discuss, fully demonstrate the thinking process of mathematics. Through variant exercises, students' appreciation ability can be improved, so as to achieve the purpose of mastering and applying knowledge flexibly. In a word, the study of mathematics in senior high school is a new opportunity and challenge for learners' ability, and the necessary strategies and methods are particularly important. The analysis of the above reasons and the guidance of methods have sparked a discussion, hoping to encourage with the teachers and students.
