Science study focuses on weekdays and is not suitable for surprise review. On weekdays, it is important to study for 45 minutes in class. Listen carefully and follow the teacher closely. At the same time, it should be pointed out that many students tend to ignore the mathematical idea mentioned by teachers: mathematical methods, and pay attention to the answers to questions. In fact, thinking methods such as "transformation" and "combination of numbers and shapes" are far more important than the answers to some questions.
Chapter 2: Finish homework with high quality.
The so-called high quality refers to high precision and high speed. When writing homework, sometimes the same type of questions will be repeated. At this time, we should consciously examine the speed and accuracy, and we can have a deeper thinking about this kind of problem every time we finish it, such as the content it examines, the mathematical thinking method used, the rules and skills of solving problems, etc. In addition, the thinking questions assigned by the teacher should also be carefully completed. If you don't give up easily, you must carry forward the spirit of "nails" and think quietly whenever you have time. Inspiration always pops up in front of you. What is important is that this is an opportunity to challenge yourself. Success will bring self-confidence, which is very important for learning science; Even if you fail, this question will leave a deep impression on you.
Chapter 3: Think hard and ask more questions.
First of all, we should know not only "why" but also "why" to understand the law: theorem given by the teacher. This is the best way to understand it. Secondly, we should be skeptical about learning any subject, especially science. If you have any questions about the teacher's explanation and the content of the textbook, please feel free to ask questions and discuss with the teacher. In short, thinking and asking questions are the best ways to eliminate hidden dangers in learning.
Chapter four: Summarize and contrast, and clarify the thinking.
(1) summary and comparison of knowledge points. After learning each chapter, you should make a frame diagram of the content of this chapter or go through it in your mind to clarify the relationship between them. Similar and confusing knowledge points should be classified and compared, and sometimes they can be distinguished by association.
(2) Summary and comparison of topics. Students can set up their own question bank. I have two sets of problem sets. One is wrong and the other is accurate. Write down the mistakes in the usual homework and exams selectively, and mark the matters needing attention with a red pen on one side. Just read what is written in red pen before the exam. I also wrote down some extremely clever or difficult problems I saw, and marked the methods and ideas used in this problem with a red pen. After a long time, I can sum up some types of problem-solving rules and write them down in red notes. * In the end, they will become your precious wealth and be of great help to your math study.
Chapter 5: Do extracurricular exercises selectively.
Spare time is very precious to us middle school students, so when you do extracurricular exercises, you should be less and better. As long as you do two or three questions every day, your mind will be broadened after a long time.
