Mathematics, physics and chemistry, as the main subject, occupies a large proportion in the examination results. If you can't learn the main course well, how can you fantasize about getting into a good school? They are closely related to us in life. From cooking to traveling, distinguishing the truth from the false and enjoying life, we can't do without mathematics and physics.
How to learn mathematics and physics well is not a difficult problem. The key is to be serious and rigorous and diligent in thinking.
By understanding the history of science, we can find that the earliest mathematics and physics belong to the same subject, and they gradually branched after continuous development. Even mathematics, physics or chemistry of the same subject are divided into many small categories, such as discrete mathematics, nuclear physics, polymer chemistry and so on. Just a hundred years ago, most scientists were chemists, mathematicians or physicists. Up to now, we still call mathematics and physics natural sciences.
This history tells us that mathematics and physics are interrelated to some extent. Learning a subject well can often provide good ideas and solutions for solving difficult problems in other disciplines.
In junior high school and senior high school, the knowledge of algebra, equation, function, analytic geometry, plane geometry and solid geometry in mathematics is widely used in mechanics, electromagnetism and optics in physics, and the physical properties in physics are closely related to the knowledge in inorganic chemistry. Understand this relationship, when you encounter difficulties in solving problems, it is often other stones that can attack jade.
If you want to learn mathematics and physics well, you must first have a serious and rigorous learning attitude. If you don't understand, you must understand with your heart. Don't be vague and don't ask for answers. In order to hand in enough homework, no matter right or wrong, you forget it. This attitude will eventually lead to a weak foundation and can't keep up with the learning progress.
A good attitude is to study hard and ask more questions. If you don't know anything, you should carefully check the contents of the textbook word by word. Books are the best teachers. What if I can't read it? Old Master Q said: A threesome must have a teacher. Ask more questions, think more and never let go.
With a good attitude, there must be a good way.
It is not a good habit to go home from school, spread out your homework and bury yourself in your homework. Take a sip of water first, and then look at what you learn every day. Compare the book with the class notes, consolidate what you have just learned, and see what the teacher missed or didn't fully explain. What the teacher didn't say is not very important. Think about whether there is a better language to describe these contents and find out their relationship with the knowledge already learned or other disciplines, so that we can better understand and remember these new knowledge.
When you start doing your homework, you should concentrate, don't be interrupted by external influences, and turn off things that may affect your attention, such as mobile phones, televisions, computers, etc.
We must solve the problem step by step, first understand the meaning of the problem, then analyze the train of thought, find the law, and straighten out the relationship between known conditions and unknown quantities, and the problem will be solved naturally.
Check it again after you finish, and don't let the ducks fly again.
It's best to start a new stove and do it again in a different way. Because sometimes we will suddenly short-circuit the cerebellum and confine it to a dead end, and we can't find it with a wrong understanding or an incorrect method.
Of course, good learning methods also include regular summary and comparison. Look at how the concepts of physics and chemistry are applied in mathematics, and how mathematical methods can help solve difficult problems in physics and chemistry. Compared with each other, it is easier to understand thoroughly and remember firmly. Mastery, learning nature get twice the result with half the effort.
There are many ways to learn, which may not be suitable for you. But there is one that is absolutely suitable for everyone. This is "reading".
Some people say: nonsense, going to school is called reading. In fact, most students don't "read"-except novels.
There is a very good stupid reading method: read chapter by chapter and read word by word. Every time you read it, write a note in the notebook, slowly stroke by stroke, and write a word "read". The words have been written and the book has been read ten times. The Chinese teacher said, "Read it a hundred times, and its meaning will show itself.". That's to teach an old fool like me to say that. I believe that you smart new generations of the century will fully understand after reading it for three or five times.
After you have carefully read the book, if you can take the time to write a book that belongs to you, you will definitely become a master in the future. The method of writing can start with translation. Translate concepts in mathematical language, turn thick textbooks into thin pages, and you will have a well-thought-out plan. A few years later, if the outline recorded in this mathematical language is clearly described in Chinese, English or classical Chinese, which is interesting and clear to all women and children, you can set up your own school and not be afraid of the world.
After learning good methods, we should strictly follow the correct steps, and integrate good methods and good habits into our lives, which becomes an instinct. At this time, your problem-solving speed will be very fast, and you will feel very enjoyable when facing the exam. Everything is so easy, learning will be the best thing in life.
