How to learn mathematics, physics and chemistry in the third year of junior high school, especially

1.Memorize the chemical properties of substances and memorize equations.

2.After completing a part of the workbook, focus on the questions that you have done wrong and can't do, and you can cut them out and paste them, and study more about the key question types.

3 Revision is important.

Chemistry in junior high school should still be very easy to learn, and there is not much content, as long as you are willing to work hard. First memorize the chemical formula or something, and then do the questions, don't do a lot, just figure out each topic. Generally, the teacher will review very systematically before the high school entrance examination, and at that time, it will be no problem to stare at the teacher to figure out each question.

Physics and chemistry are similar. Anyway, I can't copy homework or anything, I think about it, I can't think of it and ask the teacher, and in the end it's all review, and I'll be able to rush up soon. The physical and chemical high school entrance examination should not be very difficult.

Mathematics, no way, do more questions, the basic questions are good, and the high school entrance examination is OK.

Chemistry is very simple, you just have to follow the steps taught by the teacher in class. If you memorize the element symbols, chemical formulas, valencies and equations, then there is no problem with the equations and the calculation of the mass fraction of the elements.

After mastering the basic knowledge of the solution in the later stage, there is not much problem in calculating the solubility and solute mass fraction in the solution.

Also, you must be interested in chemistry, and the second is to believe that you can learn it well. A lot of scientific thinking will be used in comprehensive review, so mathematics, physics and chemistry are not separated. If you want to get a good score in the high school entrance examination, you must start from now on and do everything related to the subject seriously.

The most important thing in learning chemistry, especially in middle school, is to summarize, understand + memorize, and you can write some formulas to help memorization. Like element symbols, common element valency, metal activity order table, insoluble table, chemical equation, etc.

Pay attention to the lectures during class, take class notes in time, memorize them in time after class, and do some more questions to be OK.

Listen carefully in class, review in time after class, and pay special attention to the learning of chemical terms. Compare and summarize similar concepts and principles, and persevere, you will definitely be able to learn chemistry well.

Finding a teacher is the best way, instead of asking those of us who don't know about you, it is better to find your teacher, who has a deep understanding of you, don't be afraid of being embarrassed, your future is the most important.

Listen carefully in class and do more practice! Refresh what you've learned before refreshing! As for chemistry, remember the periodic table, the chemical equation! You have to know the names of some of the equipment you learned earlier! Understand the chemical and physical properties of matter! If you don't know how to ask questions, ask the teacher!

In fact, the knowledge of junior high school is not difficult, it will be useful to study hard, but if you really don't understand chemistry, then memorize it first, and when you memorize it back then, you will find that you also accept and understand.

Chemistry in junior high school is a liberal arts subject in science, and the learning method is simple: rote memorization and flexible application.

Listen carefully in class and practice more after class.

First of all, you don't have to be afraid of failing, the knowledge of the third year of junior high school is a big step up from the second year of junior high school, and everyone has to go through this process. You have to cultivate your interests, do a good job in the book questions, take good notes, memorize formulas, believe in yourself, you will definitely be able to achieve your goals, come on! ^_

Practice is the most important, and mathematics in junior high school is the most difficult in junior high school, with quadratic functions being the most prominent. Chemistry is relatively simple, mainly to lay the foundation for high school, and the high school entrance examination will not be too difficult.

The main thing is to listen carefully in class, don't copy homework, and do more exercises when you come down.

Chemistry is very simple, memorize the element symbols, memorize the chemical equations, and compare the atomic mass.

If I don't do well in math, physics, and chemistry in the third year of junior high school, is there a remedy? Answer: "Yes". Please see below the learning methods of physics and chemistry in the third mathematics of junior high school.

To improve academic performance, the key lies in the students themselves, first of all, hard work is necessary, secondly, to strengthen the collusion with the teachers, they have not fully mastered the knowledge points to ask the teachers in time, third, there are still 5 months before the high school entrance examination, and the mathematics, physics and chemistry of junior high school is not too difficult, to strengthen the knowledge points to summarize, do more types of questions, and the representative question types are sorted out separately, so that the review is handy, but also to expand the scope of knowledge, Don't engage in sea tactics, time is no longer allowed, and it has little effect.

1. Sort out the knowledge framework and clear the knowledge loopholes

The first step in learning any subject is to sort out the knowledge framework, the main purpose of which is to build your own knowledge system, and at the same time check the subject knowledge loopholes and fill in the gaps in time, clear the learning obstacles, and lay the foundation for future learning.

2. Lay a solid foundation and focus on basic knowledge (theorems and formulas).

Basic knowledge determines the upward space, and there are science subjects such as mathematics, physics and chemistry, whose knowledge is often interlocked, and if one link is dropped, then the latter will inevitably not be learned. Therefore, if you want to improve quickly, you must first consolidate the basic knowledge, memorize the theorem formula, and then carry out "actual combat".

3. Do more questions and do more questions

"Knowing by doing" often applies to all kinds of things, but it also applies to learning. Therefore, after mastering theorems and formulas, students should carry out "actual combat", and applying what they have learned is the foundation of learning. However, in the process of doing questions, avoid sea tactics, do more questions, but also do good questions.

If you encounter difficulties or obstacles, you must review and review the book knowledge and corresponding courses you have learned, and make up for and supplement the shortcomings and deficiencies in solving problems by being familiar with the basic knowledge, principles and related content. Generally speaking, as long as you have the relevant knowledge to solve problems, most of the problems encountered in learning can be solved by yourself, and it can even be said that with solid basic skills, there are no problems and problems that cannot be solved. Fully grasp and use the knowledge learned, independent thinking, is the most basic and the most useful way to learn the homework, can not be lazy to ask the teacher as soon as there is a problem, it can be said that casually to ask the teacher, in fact, do not understand the learning method of a performance, can even be said to be a kind of do not cherish their own study time, even, do not cherish the teacher's time a performance.

Therefore, when encountering problems in learning, we must first think independently to solve the problems and defend them, and through solving problems, we must drive the learning of various courses of Tanyan, and gradually integrate and fully grasp what we should learn. When you make full use of the above methods and do encounter obstacles in your learning, you should ask the teacher at this time, and the teacher is relatively relaxed when the questions raised by the students are fully considered, because the questions raised by the students at this moment have already digested a lot of basic knowledge, the quality of the questions encountered and raised is very high, and the efficiency of teacher-student communication is also very high. In short, before asking the teacher, you should solve the problem that you can solve through independent thinking.

A student who uses this way of thinking to study must be a student with good academic performance and a bright future.

The reason why I feel annoyed is that I am not familiar with the knowledge points and feel difficult. Learn the knowledge points first, and then do the questions. You must understand that if you apply what you have learned, you will not be able to achieve results if you do not practice.

Good way: find a famous teacher for one-on-one tutoring, especially smart. A good teacher is not only about helping with homework, but more importantly, about teaching you how to learn.

This requires you to take the initiative, take the initiative to ask your own teacher for advice, lay a solid foundation, and find a learning method that suits you.
