Suggestions on junior high school mathematics learning methods: First, the purpose of active preview is to actively acquire new knowledge, which is helpful to mobilize the initiative of learning. Before explaining new knowledge, it is an important means to read the teaching materials carefully and develop the habit of previewing actively. Therefore, cultivate self-study ability, learn to read books under the guidance of teachers, and preview with teachers' carefully designed thinking problems. For example, if you teach yourself an example, you should find out what the example is about, what the conditions are, what you want, how to answer it in the book, why you answer it like this, whether there is a new solution and what the steps are. Grasp these important problems, think with your head, go deep step by step, and learn to use existing knowledge to explore new knowledge independently. Second, think actively. Many students just listen and can't take the initiative to think, so when they encounter practical problems, they don't know how to apply what they have learned to answer them. The main reason is that you didn't consider the trouble caused in class. In addition to following the teacher's thinking, we should also think more about why we define it like this, and what are the benefits of solving problems like this. Taking the initiative to think can not only make us listen more carefully, but also stimulate our interest in some knowledge and help us learn more. Rely on the teacher's guidance to think about the way to solve the problem; The answer is really not important; What matters is the method! Third, being good at summing up laws and solving math problems is generally regular. When solving problems, we should pay attention to summing up the law of solving problems. After solving each exercise, you should pay attention to reviewing the following questions: (1) What is the most important feature of this problem? (2) What basic knowledge and graphics are used to solve this problem? (3) How do you observe, associate and transform this problem to achieve transformation? (4) What mathematical ideas and methods are used to solve this problem? (5) Where is the most critical step to solve this problem? (6) Have you ever done a topic like this? What are the similarities and differences between solutions and ideas? How many solutions can you find to this problem? Which is the best? What kind of solution is a special skill? Can you sum up under what circumstances? Put this series of questions through all aspects of problem solving, gradually improve and persevere, so that children's psychological stability and adaptability to problem solving can be continuously improved, and their thinking ability will be exercised and developed. Fourth, broaden the thinking of solving problems. Solving mathematical problems should not be limited to this problem, but should be extrapolated and thought more. After solving a problem, think about whether there are other simpler methods that can help you broaden your mind, so that you will have more choices in the process of doing the problem in the future. 5. The title must be wrong. Speaking of wrong questions, many students feel that they have a good memory and can remember a wrong question. This is an illusion. Everyone has this feeling. When the topics increase and the learning content deepens, they will find themselves overwhelmed. Therefore, wrong questions can record your own shortcomings at any time, which is helpful to strengthen the knowledge system and improve learning efficiency. Many schoolmasters got high marks because they used the wrong textbooks on their own initiative. Six, five aspects to think about the "1×5" learning method, that is, to do a problem, we must think from five aspects, and we can combine the above-mentioned "summing up the law" and "expanding our thinking". The five aspects are as follows: ① What are the knowledge points examined in this question? (2) Why do you want to do this? How did I come up with it? What else can I do? Is there any other way? ⑤ Look at the diversity of a topic and don't feel troublesome. The hardest thing to cultivate study habits is the first month, just like a rocket launch. The hardest part is the ignition and take-off stage. Therefore, once you have developed good math study habits and ways of thinking, you will be very relaxed in your future study. 7. Finish your homework independently. Now many students use some apps to help with their homework, find a photo to get the answer, or copy other students' homework. This can be divided into two situations. One is for quick photos and speed. If you do this often, you will form a bad habit of examining questions, which is easy to see at a glance and careless. Another is for convenience, which will lead to students' fear of trouble. Once the topic is a little difficult, they will start to get upset and confused. So everyone must form the good habit of finishing homework independently.
