How to improve chemistry scores in high school, how to improve chemistry scores in high school what

1. To understand more is to firmly grasp the preview, listen to lectures and review, and understand the knowledge learned at multiple levels and from multiple angles. Preview can be divided into coarse reading and intensive reading. Take a cursory look at what you're going to learn and circle the important parts under subheadings.

Then read the circle part carefully for a deeper understanding, i.e., intensive reading. During class, you can purposefully listen to the teacher explain the difficult points and answer questions. In this way, the knowledge will be understood more comprehensively and thoroughly.

In addition to understanding and memorizing the formulas and theorems, we should also deeply understand the teacher's lecture ideas and understand the "central idea" of problem solving, that is, grasping the knowledge points of the example problems and prescribing the right medicine, what theorem formulas to apply, so as to make them organized and procedural.

2. More practice refers to the practice of consolidating knowledge and the "practice" of psychological quality. Exercises to consolidate knowledge not only mean completing in-class exercises, but also completing a certain amount of extracurricular exercises. However, it is not advisable to simply "question sea tactics", and some representative question types should be done selectively.

Students with a good foundation should also do some comprehensive questions and application questions. In addition, you should pay attention to adjusting your mentality on weekdays and cultivate a calm and confident psychological quality.

3. To summarize more, we must first classify and sort out the classroom knowledge in detail, especially the theorem, and deeply understand its connotation, extension, derivation, application scope, etc., summarize the connection between various knowledge points, and form a knowledge network in the mind. Secondly, it is necessary to analyze and summarize the solution methods of various question types. It is also important to summarize your mistakes and weaknesses after your daily practice and exams so that you can overcome them later.

Chemistry is actually a subject that relies on memorization to improve, I mean high school, usually memorize more, especially those with characteristics, moderate and excessive ones, usually take more exams, practice more, accumulate slowly, and learn well if you have more.

I have experience. Chemistry is an experimental science that cannot be memorized by rote, such as equations, you must understand the principles, and you must also understand the fixed skills of some problems, such as equation system thinking, atomic conservation, difference method, etc. Hope it helps.

Theory plus practice, pay more attention to the results of experiments, and read more relevant books and exercises.

Take good notes: Be detailed and grasp the essentials. Some students do not have the habit of taking notes; Some students remember as much as they want; Some students only remember and don't think; None of this is good.

For the new lesson, mainly write down the teacher's syllabus, key points and the teacher's in-depth and enlightening analysis.

First, the chemistry score is not improving, a big reason is: the concept of the formula is not memorized, the method of solving the problem is not mastered, or the key knowledge is not understood.

The key to solving this problem is: don't pretend to understand. Therefore, when dealing with the knowledge points that you don't understand, you must be stalking and understand it! Find out what you missed and make up for it.

Second, do a good job of sorting out the wrong questions, and you can't get the same type of questions wrong twice. Clarify the problems that you don't know, and then internalize them into your own knowledge. In particular, it is necessary to solemnly remind students who want to improve their chemistry scores to prepare a wrong question book.

Recording previous mistakes can also remember regular knowledge, knowledge that you think is important and that you are easy to forget.

Third, according to the question types of the test papers, they should be tackled one by one.

The first is multiple-choice questions, which has always been the easiest type of question to improve, a question of 6 points, an all-round examination of our basic knowledge, relying on short-term breakthroughs can be greatly improved, although the college entrance examination questions are novel, but the examination is the knowledge points in the book.

And don't forget about elimination, which is a magic weapon for multiple-choice questions. Then there are the four big questions, for the four big questions, what we have to do is to study its question type structure, their answer mode is the same, you should start with a fixed answer mode, study each question.

In addition to the daily learning methods of chemistry, the skills of doing questions are also related to the test results of chemistry, and efficient questioning is not only to learn to review and analyze, but also to know how to summarize and summarize, so as to ensure that every time you finish the questions, you will have a harvest and can provide help for the next learning.

1. Master the steps of doing the questions and pass the three levels.

Examination level: It is necessary to see clearly in three aspects, see the chemical process mentioned in the question, see the conditions of the question, and see the problem to be solved. That's the premise.

Analysis: It is necessary to think about the chemical concepts involved in the chemical process and the chemical principles used, the relationship between the given conditions and the problems sought, whether there are hidden conditions and the content of the question.

Answer: The writing should be standardized, the terminology should be correct, and it should be in line with the topic.

2. Summarize after the question.

What is the intent of the proposition? What's so clever about the design of the title? What is the key to solving this problem?

Why? Is there a pattern to the questions, and can you draw inferences from them and apply them to a series of questions? What weaknesses did you expose in the process of doing the questions?

Could this question change its perspective and become something else?

3. Be good at accumulation.

The first thing to accumulate is the successful experience, and the second is the lesson of failure. Establish a file of wrong questions, accumulate the questions that are done wrong in the usual practice or exam, and often read and study, which is not only targeted, but also saves time, and can greatly improve learning efficiency.

1. Do more representative exercises: In the problem training, there are many students who just blindly pursue the amount of questions, want to improve their grades, and the effect of the sea of questions tactics is not obvious, so they should do more representative selected questions, so that the understanding and application ability of knowledge will be significantly improved.

2. Sort out the wrong questions: when doing the problem training, it is inevitable that there will be some mistakes, which are also a key point to improve the learning performance of chemistry.

3. Pay attention to the review of basic knowledge: review the basic knowledge of chemistry to a certain extent, and review it every once in a while, which can effectively improve the chemistry score.

Chemistry should pay attention to hands-on ability, some chemical equations should not be memorized, do two experiments and naturally remember, it is recommended to register for a class, online recommended by him, go and see.

If you want to learn chemistry well, you need to understand, and rote memorization will not work. Be sure to master the rules. In your spare time, you can rely on his network and let the teacher tutor you.

Also, some mantras are quite helpful. You can search for specifics. There are quite a lot of them on the Internet.

There is no class that is difficult to learn, and the most important thing is that you must not be disgusted with it, and it is impossible to love it from the beginning. Usually more back (periodic table, chemical equations...) Practice more (do some practice questions), rely on him to communicate with the teacher after class, and the grades will slowly go up, come on!

Chemistry in middle school is a relatively easy course to improve grades, and it is done in the following ways:1There are a lot of knowledge points in chemistry, so you have to memorize, and you can only improve your grades if you remember the knowledge points.

2.On the premise of remembering, you should make a summary of the knowledge points you have learned, so that after a systematic summary, your understanding of knowledge will be at a higher level. 3.

After doing the first two points well, you should do some questions, the amount of questions is appropriate, and strive to cover most of the knowledge points, to understand what you have learned, how it is tested. If you do this well, your chemistry will definitely improve your score in your future studies.

Easy to learn and easy to practice, learn artifacts in middle and high school. Users can learn and practice according to the test points and knowledge chapters, and provide you with solutions such as a question bank based on the information of big data, which can effectively improve your scores.

Make a study plan according to your own study habits;

Knowledge collation and systematization.

Knowledge connects life, often uses, and remembers more.

First, don't be afraid, cover yourself with a shadow.

Second, you should read more books, review them first when doing problems, and even junior high school chemistry.

Third, you must remember more, and you must memorize the element symbols or something.

Chemistry topics in junior high school are relatively simple, listen carefully in class, and you must complete them carefully after class, anyway, you must memorize more chemistry.

It is recommended to start learning chemistry in the third year of junior high school. Since chemistry is only learned in the third year of junior high school, the third year of junior high school is like you learning mathematics in the first grade, even if the amount of knowledge and content is not very much, only chemistry is more suitable for learning from scratch, and the effect is more obvious, which is equivalent to laying a solid foundation for you again, and it is on a certain foundation.

You can use the sea of questions tactics, but not blindly doing the questions, but to understand each question type. Of course, the equation must be able to memorize well. It's a good idea to do some tidying up and summarizing often.

Write down the questions that I don't know in a notebook, write down the problem-solving process below, and write down the ideas that I don't have, and I never mark the copied questions, so that the answers can be covered and can be done as new questions. In preparing a book, classify and organize equations, concepts, formulas. Sort out while reviewing.

In the last month of my junior year of high school, I didn't read books, I only looked at the things I organized, and because I organized them according to my habits, it looked very pleasing to the eye. I hope my advice will be helpful to you and I wish you all the best in your review.

1. The right way to learn. If you want to improve your chemistry score, you need to have the right way to study. Although chemistry is a science subject, there are many things that need to be memorized, such as:

Chemical equations, periodic table, and much more. Therefore, when senior high school students learn chemistry, they can't rely on doing all the questions, but also take time to memorize.

2. Good study habits. This is not only for the subject of chemistry, but also for studying other subjects in the third year of high school. A good study habit is the premise for you to improve your chemistry score.

Senior high school students can preview and understand the content that the teacher is going to talk about before class, prepare all the things to be used during class, and then tidy up the paper cleanly, which is conducive to concentration.

In chemistry, chemical reactions are very important, so if the first step to improve chemistry scores is to memorize chemical reactions, not only to remember, but also to understand, because in junior high school, chemistry only needs to remember chemical reactions, but high school should deepen your understanding on the basis of memory, if you are a chemistry equation hard memorized, then when the exam is written, you are likely to not answer, high school chemistry exam is not like a junior high school chemistry exam, sometimes there will be the original question, so when memorizing chemical equations, You have to learn to think.

There are many special elements in chemistry, and these special elements have the highest test rate, so we must remember these, because these are also our test points in the college entrance examination syllabus. The teacher's teaching is also focused on teaching from the chemistry test center.

There may be times when many reactions and principles in chemistry need to be inferred by ourselves, so after the teacher finishes the lecture, we must learn to judge and try to reason some principles by ourselves.

Regarding the review of chemistry in the third year of high school, the teachers of Chengdu Meibo shared with the students four tips for improving their chemistry test scores for students' reference.

1. First of all, it is clear that any chemical reaction should be considered from the perspective of the periodic table.

The reaction principle of chemistry is the question of whether the outermost electron shell is "saturated", and the valency of the state of matter is basically in line with the law of the periodic table, and only a few polyvalency are to be copied and remembered. Make a notebook specializing in chemistry and keep a "non-conventional" record, including all reactions of special colors, gases, precipitations, valences, etc.

By reviewing the reaction equations (the equations that appear in the textbook chapters step by step) and thinking against the periodic table, you can draw conclusions. You will find that with reference to the distribution law of the outermost electron shell and the order of the elements of the same main group, all the redox and hydrolysis ionization, you who were originally unable to figure out the concept, now in front of you, the gods and horses are floating clouds, everything has become clear and clear, you will find that a small periodic table is very helpful for you to learn chemistry!

2. Secondly, the key records and special elements must be kept in mind to distinguish them.

Shenma is a special element, that is, an element that can produce special gases, precipitation, and colors by reaction, as well as valence elements, combination elements (acid roots), etc., which are the test points and starting points for solving problems in chemistry in the college entrance examination. In this blog, there is a complete set of starting points for inductive chemistry problem solving, which is full of special reactions and easy-to-mix knowledge points. I hope that everyone will summarize it for themselves, and not think that with this content, you can sit back and relax.

3. Judgment and derivation should be learned.

Inorganic chemistry focuses on judgment, judging the reaction mechanism, reaction principles, such as whether the valency is equal, whether it can participate in the reaction, and how to balance, all of which are judged and deduced based on the laws of the periodic table. The judgment of organic chemistry is first the judgment of functional groups, and then the derivation of carbon chains. Grasp the reaction characteristics of functional groups, and then according to the distribution law of carbon chain (4 key positions), you can thoroughly understand the knowledge points and win the problem.

4. Compass review method.

What is the compass review method is based on a center, and then constantly expand the circle to the outside. The center of inorganic chemistry is the valency, and the center of organic chemistry is the functional group.

In inorganic, whether it is redox or hydrolysis ionization, it is the process of valency migration, so the whole central point valency is formed. The law of valency comes from the periodic table, so to learn the inorganic part, we must take valency as the center, adhere to the periodic table, and adhere to special phenomena.

In organic, with the functional group as the main axis, it is necessary to distinguish the characteristics of the functional group, the formation rules of organic compounds (mainly the carbon chain and benzene ring rules), and all organic reactions and test points revolve around this formation rule and functional group characteristics.
