First of all, preview is important.
Effective preview before class is the premise of learning mathematics well. In the preview, junior high school students need to find the difficulties and key points of knowledge and find the doubts in learning. The process of learning mathematics and improving academic performance is the process of finding problems, putting forward problems and solving problems. Boldly questioning the teacher is not a manifestation of stupidity, but a manifestation of pursuing true knowledge and being proactive. Compare the knowledge learned through preview with the teacher's teaching knowledge to see how self-study ability is, and help yourself to improve your thinking ability continuously.
Second, the efficiency of class.
Grasp the beginning and end of the class. At the beginning of the class, the teacher will summarize the main points of the last class and prompt the key content of this class. At the end of the class, the teacher will summarize and highly summarize the important knowledge points. We should not only listen to the teacher in class, but also dare to question and actively think about methods and strategies. You should "know" and "learn" yourself through the teacher's teaching, especially in the process of solving new situation problems, and realize how to think correctly.
In class, you need to concentrate on every link of the teacher's lecture and see how the teacher analyzes, solves problems and chooses the angle of thinking. Pay attention to how the students answer the teacher's questions and see what inspiration they can get from them. In class, we should not only "know why", but also "know why", and then analyze and think to solve problems and make progress in learning.
When you are in class, your energy is highly concentrated, and your understanding and absorption of knowledge will have a good effect. You can skillfully use knowledge, and you will naturally learn math well. In class, you can concentrate on positive thinking, try to keep your thoughts in tune with the teacher's thinking process, keep your eyes open, listen to all directions, and combine your hands and brains to improve the efficiency of class.
Third, practice is effective.
Math exercises are not about how many questions are done, but about the efficiency and quality of doing them. The purpose of the exercise is to check whether the knowledge is mastered and the methods are familiar. Only by accurately mastering the basic knowledge and methods and skills, and then through appropriate practice, the learning effect will be consolidated. Moderate and difficult exercises help to consolidate basic knowledge and improve thinking ability. These questions should be practiced more on the basis of accurate grasp, so that you can come up with more solutions and improve your thinking of solving problems.
Fourth, there is a summary after class.
When learning mathematics, you should spend your energy on induction and summary. To learn mathematics well, as long as you are good at summarizing, you must know what the general solution and thinking of each problem are, and use what you have learned to improve your ability to analyze and solve problems. After learning a unit, junior high school students need to establish a knowledge framework and turn the main ideas, reasoning methods and application skills into their own practical skills. In order to improve the ability of comprehensively applying mathematical knowledge to solve problems, we must be able to link the knowledge of each chapter and apply it comprehensively to avoid analogy.
Learning math well requires care and perseverance. Most of the exam questions come from textbooks, but the questions are novel, the background is complex, and the words are long and difficult to sort out. Therefore, we should pay attention to the study and training in this area, be familiar with and adapt to this kind of questions, and thus find the direction of mathematics learning.
