How to improve high school chemistry?

1. Insist on pre-class preview and active learning.

How to prepare for class: read the new lesson, find out the difficult points, and review the basics.

2) Find out the difficulty: mark the place you don't understand.

3) Revision foundation: as a knowledge preparation for learning a new course.

2. Pay attention to in-class learning to improve classroom efficiency.

Methods of in-class learning: listen carefully to the lectures; Take good notes.

1) Listen carefully: pay attention and learn actively. (2) Take good notes: be detailed and appropriate, and grasp the essentials to remember.

3. Implement after-class review to consolidate what you have learned in class.

Here's how to review after class:

2) "Post" homework: Do homework only after reading the textbook, and get twice the result with half the effort. Some students did not read the textbook before doing their homework, so they used rigid formulas or example problems to do their homework, which was half the effort.

4) Question more: Ask more about the key points and difficulties of knowledge. It can cause re-learning, re-thinking, and constantly improve the level of knowledge understanding.

5) Have a plan: arrange the extracurricular time every day; Review what you have learned in the previous paragraph; It can improve the efficiency of learning.

4. Consciously memorize and systematically master knowledge.

Methods of conscious memorization: deep understanding, natural memorization; Summarize the formula, which is conducive to memorization; Compare similarities and differences, simplify memorization; Combine reading and writing to deepen literacy.

Conscious memorization is the way to systematically grasp scientific knowledge. The method of conscious memorization varies from person to person and is eclectic. Form a conscious memorization method that suits you, so as to systematically master scientific knowledge.

Memory is very important, chemistry is nothing more than substances and reactions, memorize the physical and chemical properties of typical substances, practice more, do not depart from the textbook, memorize important chemical reactions, draw inferences from one another, make a summary of knowledge in each chapter, you must do it yourself, which should be able to do a good job of combing knowledge. Hope it helps.

Read more notes and do some typical questions. Familiar with the equations and some rules. The key is note-taking.

It's good to have a feeling. Raise interest.

I don't think there is any trick, as long as you pay full attention in class, listen carefully and follow the teacher's ideas, complete the homework assigned by the teacher on time and don't procrastinate, and solve problems in time. I came from that era, that's what I do, I don't usually engage in any problem-solving tactics, and I've always been against this. The mastery of knowledge lies in understanding, especially in science, that there are rules to follow.

Many years after graduating from high school, I can still remember the current exercises that are similar to those we had back then, and I still remember very clearly how I thought about solving them.

Chemistry is not a pure science subject, there are many things to memorize, and on the other hand, to master things with strong regularity.

I even used it as a liberal arts science at the beginning, and it worked pretty well.

Chemistry should be the best subject in high school science courses! But it's not easy to learn chemistry well! It's useless to read too much!

The key is to solve more questions, summarize more, and make a wrong question book, so that you can figure out every wrong question in the college entrance examination, and chemistry is not a problem when you get to the college entrance examination!

Error books all have a theme.

The knowledge of chemistry is relatively trivial, so you need to memorize more, and you can use chemical equations to put together the knowledge points

Chemistry is like liberal arts, the key is to memorize.

Memorize chemical equations and chemical names, you don't have to memorize them, you have to understand them, and if you understand them, you will write a group.

Remember the principle of reaction, don't memorize any equations. That's an endless hunger.

High school chemistry shouldn't be too difficult, do more experiments, some chemical formulas can be memorized smoothly, and now I forget them, almost 10 years ago.

Chemistry is equivalent to the liberal arts in science, and you can learn more by remembering more things, memorizing and practicing more.

Chemistry is a discipline between liberal arts and science, which requires memorization + continuous practice.

The most important thing is to master the basics, and then it is to do more questions, think more, draw inferences, and ask the teacher in time if you don't understand.

Proficient in writing chemical equations. Categorize and summarize the various equations, and which equations are available under each requirement. How the various equations evolved.

Find the rules, and when you learn it, you will find that all chemical reactions have their own classification and attributes, and they are always the same. Another point is not to use habitual thinking to deal with the type of question you are familiar with.

After the new curriculum reform, the examination pays more attention to the basics, and at present, as long as you master the basic knowledge and basic question types, there is no problem in getting a high score in chemistry.

In terms of how to learn, how to ask, and how to do questions, have you read books and done questions in a solid way? There are a lot of students in my class, who usually sleep, read magazines, and play with their mobile phones, and suddenly one day they want to do it overnight and then ask me, "Teacher, how do you study chemistry well?" If there really is such a universal treasure book, then is there a latecomer?

Let me give you an example of reading a newspaper that you are familiar with. Only when you recognize Chinese characters and understand their meanings can you read them, and you can understand them. That's when you're able to talk about reading skills.

What's the point of talking about reading skills when you don't understand words or words?! Techniques and methods can only be the icing on the cake after mastering the basics. And after you have mastered the basic words, you can naturally understand the skills such as fast reading, etc., at this time, feel free to aim at the master's point, in order to make a reference for your own learning.

Other people's experience is someone else's, not necessarily suitable for you, only through your own understanding and experience can play a role, and the experience of being rigid will make you more confused and hesitant.

This reminds me that our students buy materials first to learn chemistry, and to learn English, they also buy equipment one after another, but they don't learn well. The reason for this is that they are always looking for objective reasons, and subconsciously always hope for shortcuts.

If you want to ask if there are any skills and methods in chemistry, of course there are, what difference method, conservation method, etc., those are all ways to solve a certain type of problem. I can also give you some knowledge points of chemistry in the college entrance examination, which I think can be said casually because they are familiar and do not need to think about it. I understand them as well as you understand that one plus one equals two.

However, this is only because I teach chemistry and I deal with it every day and am familiar with it. Familiar with 300 Tang poems, I can't chant poems.

Your question is too general and abstract. There are only suggestions that will help you, not suggestions that will help you study!

After saying ugly things for a long time, I finally annoyed you by saying: From now on, master the basics, and do targeted questions.

Do the questions, and the same questions can be solved.

Memorize, memorize basic concepts, equations, and principles, and apply them flexibly in problem-solving.

I scored 104 in chemistry in the college entrance examination, and I relied on this trick.

Chemistry needs to remember a lot of things, listen carefully in class, follow the teacher's ideas, take notes, and at the same time absorb and master the knowledge points in class, saving review time after class.

Both chemistry and mathematics have strong logical analysis and reasoning, and if mathematics is good, chemistry will also be good. But the main thing is to see more and practice more and lay a good foundation.

Chemistry is basically something to memorize, but you have to memorize it after you understand the mechanism, which is much easier, because I studied chemistry.

According to the classification of the main group, the periodic table of elements, the properties of the elements of each family are similar, after knowing the commonalities, and then to understand each small difference, it is OK to write them down.

Chemistry has to be memorized, but not just rote memorization, you have to discover and summarize some of the rules by yourself, for example, when memorizing the steps of some important experiments, you can imagine that you are really doing experiments, and at the same time think about what kind of order it should be, and then add some professional language, and you can memorize it quickly. And it's very important in chemistry to memorize equations, but don't memorize them, because you can't remember them, and for the equations that you find difficult, you can write down the substances that are reacting, and then you can close the book, and you can make up the substances that you produce based on redox, valency changes, and so on, and then you can think about and summarize the equations that are correct in the book. It's a very interesting approach.

With this stupid method, I can get a perfect score in the chemistry part of the science, but the physics is very miserable. . .

Remember, chemistry is actually a liberal arts in science.

To improve quickly in high school chemistry, here are some suggestions:

Establish a knowledge framework: Chemistry is a fundamental discipline with a wide range of knowledge points and interrelated knowledge. Building a clear knowledge framework is fundamental to learning chemistry.

Multiple exercises: Chemistry is a very practical subject, and you can improve your understanding and application of knowledge by doing a lot of exercises. You can choose the exercises from the textbook or find some supplementary workbooks to practice. When you encounter a problem, you can seek help from your teacher or classmates.

Focus on experiments: Chemistry is an experimental subject, which can not only deepen the understanding of knowledge, but also cultivate experimental skills and scientific spirit. In the experiments of the school or laboratory, the experimental process and results should be carefully recorded, and the experimental phenomena and causes should be analyzed.

Participate in more discussions: Participate in class discussions or group learning, communicate and share understanding with classmates, and deepen your understanding and memory of knowledge. You can also join a chemistry learning community or forum to communicate and learn from other chemistry enthusiasts.

Make a study plan: Make a reasonable study plan, break down the chemistry learning into small goals, and study in a step-by-step manner. Arrange your time reasonably, insist on a certain amount of study every day, and avoid procrastination.

Auxiliary tools: You can use scientific and technological means to improve learning efficiency, and use auxiliary tools such as chemistry learning software, mobile app or ** course. These tools can provide more learning resources and practice questions to help consolidate and expand knowledge.

Communicate with teachers: When you encounter problems and confusion in learning, ask them for advice in time. Teachers are the best learning resource, they can give guidance and advice to help solve doubts in learning.

Think and practice: Chemistry is a discipline that requires thinking and practice. In learning, we should think more about the logic and application of the learning content, and try to apply the knowledge to real life. Through practice and exploration, students will deepen their understanding and memory of chemistry.

Most importantly, maintain an interest and passion for chemistry. Chemistry is an interesting subject, and only by loving learning can you keep making progress in your studies.

If you want to ask which stage of study is the hardest to improve your grades, high school definitely comes first.

Whether it's a freshman in high school, a sophomore year who is trying to improve himself, or a senior year who is about to end his high school life, improving his grades in the past three years is not achieved overnight.

If high school students want to improve their grades, they must first use the right study methods, otherwise they will not only waste time if they take the wrong path, but also cause psychological pressure on themselves.

First, don't compare your grades with others.

High school students' grades, while important, are not used to compare capital.

Sometimes it's easier to say that you get a little higher. If you have low grades, you will fall into a slump.

Before all the efforts, students must keep in mind that grades are used to show the appearance of their hard work, not to compare capital, maintaining a good attitude, facing study and life with a positive attitude is the most important.

Second, weak subjects should be re-learned from the basics.

It is very common for students to deviate from the subject in high school, and the solution for this situation is generally to work hard to consolidate the questions.

But for a subject that you don't know much about, if you don't have a solid foundation, you can't build a tall building.

Don't find yourself seeing nothing, so that the method of filling in the blanks will not work fundamentally.

3. If you encounter problems that you don't know, you should deal with them in a timely manner, and you can ask the teacher and your classmates.

When high school students encounter problems that they can't do, there are generally three solutions, one is to meditate, one is to ask others, and the other is to let go.

The second of these is the most labor-saving and the most able to promote the active mind.

High school students should not put too much psychological pressure on themselves when studying.

No matter how good the learning method is, it needs to be slowly improved after applying it to yourself.

Only by trying to combine these methods in the learning process can you improve your grades.

1. Find out the reason for poor learning and poor grades, whether it is because you can't remember the knowledge points, or can't understand them, or other reasons, and analyze the reasons before you can prescribe the right medicine.

2. After finding the reason, modify the learning method, and if you want to improve your chemistry score, you need to have the right learning method. Although chemistry is a science subject, there are many things to memorize, such as: chemical equations, periodic table and so on.

Therefore, when senior high school students learn chemistry, they can't rely on doing all the questions, but also take time to memorize.

3. Cultivate interest in learning chemistry. As the saying goes, "interest is the best teacher". No matter what course you study, you must first be interested in order to learn well, and if you are not interested but are forced to learn, you will not learn well after all.

4. Develop 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.

5. Pay attention to chemical experiments. In particular, the process, principle, results and use of experimental equipment in chemical experiments must be mastered.
