General comments (new)
General methods of junior high school mathematics learning 1. Highlight one? Diligence? Word (overcome one? Idle? Word)
Mathematician Hua said: intelligence lies in learning, and genius lies in diligence?
? Diligence is a good training, and one point of hard work is only one point;
When we study, we should highlight a word of diligence and conquer one? Lazy? Word, how to stand out? Diligence? word
? Cong? Is there any diligent method? Literally speaking, we should be diligent in five aspects. Hard-working ears and eyes? (Listen with your ears, see with your eyes, and receive information)
? Careful? Discuss and answer questions instead of talking and digesting information? Hard-working? (Good at thinking, positive thinking, absorbing and storing information) Are the above four points enough? No. This word is still flawed. Supplement? Hands?
? Handy？ Practice more, not just doing problems, making courseware and making models.
Is such a person smart?
To improve learning efficiency to the greatest extent, we must first listen carefully in class (this is fundamental). Go home and review before you do the problem. I can't listen well in class and I can't digest my knowledge.
2. There are two main points to learn junior high school mathematics well, which should be highly valued:
To learn math well, one must (do) and the other must (use your head).
Thinking is to learn to observe and analyze problems, learn to think, don't do it as soon as you get the problem, find out what is the connection between the known and unknown imagination, and ask more why.
Doing it means practicing more and doing more problems, do you want it? Never leave your hand? (martial arts)? Don't leave your mouth? (singing)
Are you classmates? Never digress? These two points should be remembered.
? Use your head and hands to maximize the efficiency of your brain?
3. do it. Three times?
Have you ever heard of it? Failure is the mother of success? Ever heard that repetition is the mother of learning? Really?
Bacon (18-19th century British philosopher)? Knowledge is power?
? Repetition is the mother of learning?
How to repeat it? Let me explain it to you:
? Listen carefully in class and push your thinking.
? Watch after class?
? Before the exam?
4. Value? Fourth base?
Reading a textbook well is the main basis for teaching and senior high school entrance examination;
Take good notes, which is the crystallization of the teacher's years of experience;
Do a good job of cleaning up a problem set, which is to broaden the knowledge;
Take a class note, and everyone had better prepare a set of wrong questions.
