What are the tips for learning mathematics, physics and chemistry? Urgent!

I'm also a freshman in high school, and I'm studying science. I wasn't good at physics before, and then I went to the teacher and what should I do. Because I was the head of the key class in our school, I always felt that I had to study well.

First of all, I think we must have the determination to learn well, second, ask the teacher which book is good, buy one and insist on finishing it, one is enough, and third, insist on asking the teacher questions every day. You have to work your own, and at the same time, you have to listen to the teacher's advice. It must work, and I did it.

If you have a trick, everyone will become a master!

You should consult the teacher, let the teacher analyze whether your learning method is suitable for you, and consult the teacher or students with excellent grades to see where they start, what kind of thinking they use, choose the learning method that suits you, and then continue to practice to achieve practice makes perfect.

Finally, I wish you to become the Prince of Science!

Hey! It's only a freshman in high school.

This blow will not work.

Actually, it was only later that you realized that the blow was more than just a little.

In fact, these three subjects are to do more questions, read more books, and most importantly, you have to find the feeling.

That feeling of having an idea as soon as you see a question.

Do the questions. It's better to ask the sea.

The more you see, the faster you improve.

But you must do it yourself, you can't hold the book and read the example problems, even if you read it, you have to do it yourself again.

Problem: A difficult question a day!! Then you won't have any problems, of course, make a note so that you can review

Comparative thinking methods.

Reverse thinking approach.

Naturalization of the method of thought.

Combination of numbers and shapes, thinking methods.

Categorical discussion of ideological methods.

I think the most important thing for mathematics, physics and chemistry is a change in thinking. Don't learn it with rote thinking. Don't just copy notes in class, it won't help much.

Let me talk about my suggestions, the first thing is how to prepare, generally in the summer or winter vacation, these two time periods are relatively long, you first put these three subjects in advance, the basic content of your own self-study, do not understand the content of your own marking.

After that, it's a formal class, and it's very important for the teacher to follow his train of thought when talking about problems, and at the same time to see how the teacher explains the problems that I used to mark.

The second word is to touch the class bypass to change yourself when doing the question, and when you can't, you must ask the teacher or classmates, in short, you have to understand the specific mode of the question, so that it is not a problem to encounter other questions.

The last word is to review, I think it is mainly based on the basic formula, and the other is mainly based on the key question type.

Listen carefully in class, and then buy something extracurricular to do by yourself, not only in a question that you have to understand, but mainly in learning methods and ideas.

Let's start with the concept. Memorize the bold text on the book. Do the basics. Generally speaking, the first eight fill-in-the-blank questions, the first three multiple-choice questions, and the big questions except the last two are all basic questions. Get them done first.

Learning methods of mathematics, physics and chemistry There is a sentence that shows the characteristics of each subject of science: "Physics is difficult, chemistry is complicated, and mathematics learning problems can not be completed", many students reflect that physics is difficult to learn, not easy to understand, facing a series of physics problems, just like seeing flowers in the fog, there is always a sense of not knowing the true face of Lushan, in fact, I think it is difficult to find out that you are exploring and mastering the learning skills of the subject, how to learn physics well, I will talk about my feelings, hoping to play a role in throwing bricks and leading the jade First, learn to repeatedly analyze and ponder the concept of things Whether you can learn physics well, to a large extent, depends on whether you can understand the concept of physics thoroughly, because of its abstract nature, there is always a sense of: "can only understand, can not be spoken", such as "energy", "inertia" and so on these concepts, relying on the teacher's "words" alone can not express the true meaning of the concept, and only by doing their own "will" can we truly appreciate its full connotation, this "will" feeling can only be experienced by our repeated analysis and pondering of the concept, the so-called " For example, the concept of "friction" is defined in the book:

When two objects in contact with each other move relatively, a force will be generated on the contact surface that hinders the relative motion, and this force is called friction force", after analysis, we can first find out the key words in the concept, "contact with each other", "relative motion", "contact surface", "hinder relative motion", and then ponder and experience the meaning of these words. "Mutual contact" refers to the primary condition for the occurrence of friction, and it can be associated with the difference between gravity and magnetism, but objects that are not in contact with each other must have friction. Obviously not, the word "when" reveals that the generation of "friction" must be accompanied by "relative motion", so what is "relative motion"?

The word "relative" should refer to "two objects in contact with each other", so it is realized that the basis for judging whether there is friction between two objects in contact with each other should be to see whether the two objects have "relative motion" rather than whether the two objects have "motion", "contact surface" tells us where the friction force is generated, and "hindering the relative motion" explains the role and direction of the "friction force", and its role is to hinder the "relative motion" rather than "hinder the motion". Then its direction should be opposite to the direction of "relative motion" rather than the direction of "motion", and from this we can suddenly realize that friction is not always resistance After such repeated analysis and pondering, we will naturally be clear and thorough about the conditions, position, effect, and direction of friction, and there will be a sense of paradox

How to learn mathematics, physics and chemistry well, I have written him into an article on my **, check the address and many classmates have asked me this question, you can also take a look at the replies to other questions.
