What if junior high school math is not good? What methods can I preview actively?
The purpose of preview is the process of actively acquiring 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, we should pay attention to cultivating self-study ability and learning to read. 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.
Active thinking
Many students just listen and can't think actively in the process of listening, 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!
Be good at summing up laws
Generally speaking, there are rules to follow in solving mathematical problems. When solving problems, we should pay attention to summing up the law of solving problems. After solving each exercise, we 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.
Methods to improve math scores. Find out what efforts we can make in knowledge.
The key is to be prepared for knowledge. Before the exam, you should check if there are any loopholes in the math knowledge you have learned in junior high school, and if there are any forgotten or confused places. Secondly, be prepared to solve common mistakes, and then look at your own error notes. If there is no wrong book, you can find out the papers you have done before. Look at the revised part, that is, the wrong place. Try not to make mistakes or make fewer mistakes when writing the answer sheet for the senior high school entrance examination, that is, not to make mistakes.
We must have confidence in ourselves and the future. Mentality is the most important reason that affects the exam.
When you enter the examination room, you must have a domineering attitude. Be confident, believe that you have been in junior high school for 1000 days, reviewed for more than 300 days, worked out 3,000 to 4,000 questions, trained for 1000 days, and spent some time fighting. Now is the harvest time, and you will get good grades.
On the other hand, if you lack confidence as soon as you enter the examination room, it will definitely affect your own play. It doesn't matter if you don't study well on weekdays. A journey of knowledge life in junior high school is not the end of life. As long as you work hard, living anywhere is the starting point ... as long as you are negative, living anywhere is the end point.
Examining questions is very important.
Success also examines questions, and failure also examines questions. How to review the questions?
(1) What are the known conditions of this question? Can I separate the known conditions?
(2) What is the goal of the solution? What are the requirements for solving?
(3) Can you draw a picture to help you think? Many problems are caused by not seeing the meaning clearly. The more you do, the more mistakes you may make.
(4) What is the relationship between the given known conditions? Can you find implicit conditions from it?
(5) What is the relationship between the known conditions and solving the target?
Can you get ideas to solve the problem from it? Looking for a threshold to enter the door?
(6) Can we deduce something useful from the known conditions first?
(7) Observe the whole topic and associate the questions I have done in the past.
