Learning crown education: how to learn junior high school mathematics well
Listen carefully in class and review in time after class. The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay special attention to the learning efficiency in the classroom and seek correct learning methods. Keep up with the teacher's ideas in class, actively develop thinking, predict the next steps, compare your own problem-solving ideas with what the teacher said, and actively raise your hand to speak. The benefits of lifting a finger are really many! Consolidate the knowledge learned in class. Exercised his eloquence. Those vague ideas and mistakes can be taught by teachers. It's killing three birds with one stone. In short, listening should be done with hands, mouth, eyes, ears and heart. Think about it. Most students who learn mathematics well are students who love to think and speak actively in class. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. In a sense, you should not create a learning way of asking questions if you don't understand. For some problems, because of their unclear thinking, it is difficult to solve them at the moment. Let yourself calm down and analyze the problems carefully and try to solve them by yourself. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system. Do more problems properly, develop good problem-solving habits and cultivate the necessary problem-solving ability. If you want to learn math well, it is inevitable to do more problems, and you should be familiar with the problem-solving ideas of various questions. At first, we should start with the basic problems, based on the exercises in the textbook, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general law of solving problems (so we have math homework every day). For some wrong-prone questions, you can prepare a set of wrong questions, write your own thinking and correct problem-solving process, and compare them to find out your own mistakes so as to correct them in time. We should develop good problem-solving habits at ordinary times. Let your energy be highly concentrated, make your brain excited, think quickly, and enter the best state. Practice has proved that the more critical it is (during the exam), the problem-solving habits you show are no different from those you usually practice. If you are careless and careless when solving problems, it is often exposed in the big exam, so it is very important to develop good problem-solving habits at ordinary times. 3) Review and preview. The review of mathematics is arranged every night. After finishing my homework that day, I will briefly look at the new knowledge I will learn the next day, and then recall what the teacher said. When I sleep in bed, I will "watch" the teacher's class in my mind like watching a movie. If you have any questions, get up and read them until I understand them. Use every Sunday to make a summary of the week's homework to review the preview. This is good for learning mathematics. If you master it firmly, you won't forget it. 3. Cultivate good study habits 1. Thinking: Thinking is the core of mathematics learning methods. Thinking is of great significance in learning this course. When solving math problems, we should first observe, analyze and think. Thinking can often find out the characteristics of the topic and find the breakthrough and simple method to solve the problem. Around us, students who really study well have the habit of thinking and thinking hard, so the more they use their brains, the smarter they become, and the more they think hard, the better they become. 2. Try more hands-on: hands-on helps to digest what you have learned and achieve mastery. The new curriculum reform pays attention to the change of students' learning style and the process of knowledge formation. Every lesson in the textbook is permeated with this concept of curriculum reform, and almost every lesson is arranged by "trying" or "doing", so we can make full use of it. You can do more homework, try, do, draw and write before class, which is good for learning geometry well and stimulating your interest and confidence in learning mathematics. For example, when learning the expansion diagram of a cube, we can try to draw all the expansion diagrams of the cube, cut them out and fold them to see if they are correct. And try to summarize its laws. The process of hands-on participation is also the process of knowledge formation, and at the same time, we feel a sense of accomplishment and happiness in the learning process. Personal experience will be very helpful for students to learn mathematics well. 3. Learn to constantly sum up experience and integrate all the knowledge you have learned. For example, we recently talked about linear equations and linear inequalities of one variable, as well as linear equations of two variables and linear inequalities of one variable. We should compare the similarities and differences of their solutions. When solving practical problems with equations (groups) and inequalities (groups), their thinking and steps are the same. The key difference between them is that if the topic is given a certain equivalence relation, the column is the equation (group), if the column given uncertainty is the inequality (group), if we summarize it like this, then when will the equation (group) and inequality be listed? When you form a summary and contrast, you can easily learn math well.
