The method of improving math scores quickly in the second day of junior high school 1. Read textbooks carefully and improve self-study ability.
(1) Preview reading before class. When previewing the text, you should prepare a piece of paper and a pen, and write down the key words, questions and problems that need to be considered in the textbook. You can simply repeat the definitions, axioms, formulas and rules on paper. Key knowledge can be approved, marked, circled and marked in textbooks. Doing so not only helps us to understand the text, but also helps us to concentrate on listening in class.
(2) Classroom reading. In the preview, we only have a general understanding of the contents of the textbooks we want to learn, and not all of them have been thoroughly understood and digested. Therefore, it is necessary to further read the text in combination with the teacher's teaching, so as to grasp the key points and solve the difficult problems in preview.
(3) Review reading after class. After-class review is an extension of classroom learning, which can not only solve the unresolved problems in preview and classroom, but also systematize knowledge, deepen and consolidate the understanding and memory of classroom learning content. After a class, you must read the textbook first, and then do your homework; After learning a unit, you should read the textbook comprehensively, connect the content of this unit before and after, summarize it comprehensively, write a summary of knowledge, and check for missing parts.
Second, the cultivation of self-study ability.
Develop the habit of thinking and strengthen the understanding and memory of knowledge. Independent thinking is an essential ability to learn mathematics. When studying, students should think while listening to lectures and do problems while reading books. Through your own positive thinking, you can deeply understand mathematical knowledge, sum up mathematical laws, and solve mathematical problems flexibly, so as to turn what the teacher says and what is written in the textbook into your own knowledge. Don't think you understand what you should remember and recite. We should remember the definitions, laws, formulas and theorems of mathematics, and use them to deepen our understanding when solving problems on the basis of memory.
Do more exercises and summarize the methods of solving problems. When learning mathematics, you must do problems and do them properly. The purpose of doing the problem is first to master and consolidate the knowledge learned; Secondly, initially inspire the flexible use of knowledge and cultivate the ability of independent thinking; The third is to achieve mastery through a comprehensive study and communicate different mathematical knowledge. When solving a specific problem, we must carefully examine the problem, firmly grasp all the conditions of the problem and thermal reaction, and don't ignore any condition. There is a certain relationship between a problem and a class of problems. You can think about the general idea and general solution of this kind of problem, but it is more important to grasp the particularity of this problem and how to grasp the difference between this problem and this kind of problem. Is there a simple solution? Think and summarize while doing, and deepen the understanding of knowledge through practice.
Be good at asking questions and cultivating ability. Being good at finding and asking questions in the process of learning is one of the important signs to measure whether a student has made progress in his study. Experienced teachers believe that students who can find problems and ask questions have a greater chance of success in learning; On the other hand, students who ask three questions and ask any questions themselves can't learn math well. So, how can we find problems and ask them? First, we should observe deeply and gradually cultivate our keen observation ability; Second, you should be willing to use your head instead of thinking about it. Of course, you can't find any questions and you can't ask any questions. After discovering the problem, through your own independent thinking, you should consult teachers, classmates and parents humbly when the problem is still unresolved. Only those who are good at asking questions and learning with an open mind can become real strong learners.
Expanding reading: What are the skills of taking the exam in senior high school entrance examination? First, make full use of the ten minutes before the exam, read through the whole volume, and grasp the overall situation.
The senior high school entrance examination stipulates that "distribute the examination papers ten minutes in advance, so that candidates can fill in the admission ticket number, seat number and name, and fill in the answer sheet, but they can't answer." Candidates can use this time to browse the test paper, grasp the overall situation of the test paper, roughly understand the number of problem solving, the types of questions, the distribution of scores, understand the difficulty of the test paper, and know which questions are easy and which ones are difficult, so as to make correct moves.
Second, scientifically coordinate the order of answering questions, first easy and then difficult, and reasonably control the time of answering questions.
Most of the math test papers in the senior high school entrance examination are basic and intermediate questions, and there are few questions. In order to make the test-taking mentality in the best state, candidates should scientifically coordinate the order of answering questions and reasonably control the time of answering questions. The first step is to do questions that are easy to score and require little calculation, improve the score quickly, and experience the sense of success, which is conducive to eliminating the tension at the beginning of the exam; The second step is to do problems that have certain problem-solving ideas, but need to calculate and express time, and constantly supplement the scores. At this time, most of the topics are completed, and the psychological success is constantly experienced, which makes the thinking in an exciting state and is conducive to activating the knowledge context in the brain; The last step is to concentrate on "firepower" and attack the so-called problems in your mind in a relaxed and stable state without worries. Don't do it from beginning to end. Once you encounter a hurdle, you will spend too much time, which will affect the answers to the following questions, causing a heavy psychological burden, leading to poor examination, missing this and that, confusion and repeated loss of points.
Third, carefully examine the questions, seek speed and gain time on the basis of accuracy.
Read the general topic at least twice, find out the meaning of the topic, find all the information, find out the trap in the topic and dig out the hidden conditions. The more cautious you are about familiar graphics and topics, don't rely on old experience, old ideas and old methods, and take it for granted to answer questions without seeing them clearly. Because graphics are the same as content, it doesn't mean that the questions are the same. Read the new questions carefully and patiently for several times. List the conventional reflections of known conditions one by one, and then find a "bridge" to connect the known quantity with the quantity to be solved. Only on the basis of accurate inspection can it be fast.
Fourth, the answer is standardized, and no "wrong" points are lost.
Candidates understand the grading standards and insist that "deduction will be exempted; Score points and write more; The key points cannot be saved, the answers are standardized, and the writing format is correct. It is not easy to lose points, but you can also get more scattered points in the questions that you can't completely solve. In addition, the handwriting should be neat and clear, the surface of the paper should be neat, and the order of answers should generally be from top to bottom, from left to right, and so on. These will make the marking teacher not deduct your points where he can, but give you points where he can give or not, so that you will benefit a lot and not be "wronged" to lose points.
