What are the good learning methods to learn mathematics, physics and chemistry in junior high school

Learning strategies for beginners – "Complete", "Clear", "Easy", and "Fast".

"Complete": That is to say, all the basic things within the scope of the requirements of the college entrance examination, such as basic knowledge points, basic problem-solving skills and examination skills, etc., you must learn "complete", and there must not be a certain part of the knowledge that has not been learned.

Clarity": If you have doubts about the basic things, whether you are learning them now or those you have learned them before, you must understand them as clearly as possible. It doesn't matter how many reference books you read, how many people you consult, or even learn from scratch.

If your foundation is too poor, you can use methods such as asking a tutor to make up the lessons, listening to the lessons with your junior classmates, and reading the textbooks and reference books you have learned before.

"Easy": Mainly do simple and basic questions, do a small number of moderately difficult questions, and try not to do difficult and comprehensive questions. Only master basic, general problem-solving skills, and give up complex and overly ingenious problem-solving skills.

"Fast": It does not mean that you are "fast" in doing a certain problem, but that you must complete a sufficient amount of learning tasks in a period of time, such as a few weeks or a month, such as completing the basic questions in a reference book, reading a previously learned textbook, and so on. If you are in the elementary stage of mathematics, it may take a long time to do a certain problem, at this time, don't worry, you can read some reference books, ask teachers and classmates, as long as you can really understand some problems, you are improving.

If you are in the primary stage of mathematics, if you do not have enough time to study mathematics every day, you can temporarily give up the standardization and rigor of doing problems, give up difficult problems and comprehensive problems, give up "one problem with multiple solutions, multiple problems with one solution", give up ingenious problem-solving skills, and so on.

The learning strategies of intermediate stage students - "fine", "ruthless", "deep", "fine" and "accurate".

"Fine": Do the question is not expensive, don't be greedy, make a count.

"Ruthless": When doing the question, the "ruthlessness" is constantly increased, and the question that can be done must be made; If it is possible, do your best to make the problem; Continuously increase the number of exercises you do every day, and you will do 30 questions yesterday and 31 questions today.

Continuously improve your "hard work" when doing time-limited mock questions and exams. No matter what the topic, when doing time-limited mock questions and exams, you must try it and do your best to make it; Be quick when you do the questions! If you can do a question in one minute, don't use it in two minutes.

"Deep": think more deeply and summarize more. Think deeply about how to use basic definitions, formulas, and theorems, think deeply about the deep connections between different topics, and think deeply about the same solutions to different problems.

"Fine": to be careful, to develop rigorous, rigorous study habits. You can give up certain questions, such as difficult questions, comprehensive questions, strange questions, etc.

However, for basic questions and moderately difficult exercises, the solution ideas, problem-solving skills and problem-solving methods should be carefully mastered, and every small problem should not be missed; For questions that you feel are important and typical, after completing the questions, you should also compare them with the standard answers to see if your process is complete.

Then do more questions, and it's still okay to have sea tactics.

Mathematics, physics and chemistry in junior high school are relatively simple, and they are the most promising subjects to get a perfect score.

Here are some tips for learning mathematics, physics and chemistry well.

One. High-quality lectures (this applies to all subjects).

It is important to pay attention in class. Remembering that listening in class is more important than taking notes. There is a group of students who remember their notes very carefully and are clearly organized, but they are not good at doing the questions.

Why? Because his classes were all used to take notes, he didn't pay attention to listening at all. The class is mainly listening, and you need to memorize it quickly and simply, and then make it up again.

A math teacher once said that his class wanted his students to be "high." Take a closer look at this "Hi". Students follow the teacher's train of thought and listen attentively to the class, indulge in it, understand a knowledge point, and understand a question, and the joy in their hearts is indescribable.

It's really learning "Hi".

Two. Completed assignments with high quality.

Assignments are a reinforcement of what has been learned in class and must be done meticulously. Before writing homework every day, recall whether you have mastered what you have learned today, and if you have any questions, it is recommended to review the textbook and notes before doing homework. The process of doing homework should be timed.

How many minutes you estimate and how many minutes you actually use, and gradually you will have more accurate control of the time you have to write your homework. Every assignment is considered an exam, and it cannot be delayed, and it is completed within the specified time.

Three. Learn from the past.

The knowledge points of science learning are linked one by one, so you can't learn the new and forget the old, and you must review it from time to time. Especially in junior high school chemistry, there are many things that need to be memorized, and they must be reviewed and memorized frequently.

Four. Correct mistakes in time and use the wrong question book well.

One of the most effective ways to improve scores in mathematics, physics and chemistry is to correct mistakes. We can prepare a book of mistakes for each subject of mathematics, physics and chemistry, accumulate the wrong questions, write down the reasons for the mistakes, and do it all over again, and even do the difficult mistakes two or three times. The accumulation of mistakes can be copied directly, or the mistakes in the paper can be cut and pasted directly (provided that the paper is useless), the latter is more time-saving.

Before each big exam, take out the wrong question book and look through it, and remind yourself not to make the mistakes you have made again.

Five. Expand appropriately.

On the premise of completing the school learning tasks, mathematics, physics and chemistry should ensure a certain amount of practice every day. In practice, you can choose your weak points first, most of them can choose basic questions, and then choose one or two difficult finale questions to expand your thinking. Remember that quantitative change will inevitably lead to qualitative change.

Six. Good at summarizing after the exam.

Whether it is a small test or a big test, you must analyze and summarize the test paper after the test. See why you are wrong, whether it is because you have not mastered the knowledge points or because of careless miscalculation. Carelessness is actually caused by insufficient practice and proficiency.

Seven. Know how to give up.

Students who are not too good at the degree will not be able to do the math finale question in the big exam every time, at this time you don't panic, first do what you will know in front of you, the finale question depends on the situation, you can do a question to do a question, you can do two questions to do two questions, and the third question really won't give up. (Based on experience, the third difficult question in the finale of junior high school mathematics will not be low.

The learning method is universal. Although it is about how to improve the score of mathematics, physics and chemistry, in fact, these small methods are used well, and other subjects are still improved.
