How to study physics and chemistry in high school? 20

It's similar to my situation, I also dangled in my first year of high school, not only in chemistry, but also in other subjects. When I was a sophomore in high school, I used the winter and summer vacations to re-study the knowledge of the first year of high school, did a lot of questions and read many textbooks, and then made up for the knowledge that I didn't learn well, which was a painful thing, but it was very effective. Now that I'm in college, majoring in chemistry, you can communicate with me if you have any questions.

By the way, I forgot to tell you that the definitions and formulas should not only be memorized, but also memorized comprehensibly, and then use the formulas to do the questions, so that you can be familiar with them.

1. Maintain a positive and enterprising attitude towards learning problems.

2. Start learning quickly.

3. Once you start studying, you have to work hard. It is necessary to divide the learning materials with a large mechanical memory content into several parts that are easy to grasp, and study these short materials frequently in order to grasp them firmly.

4. Learn with the intention of learning and memorizing.

5. Establish sub-goals for learning and keep them firmly in mind.

6. Make learning as meaningful as possible.

7. Imagine the meaning of newly learned concepts and terms.

8. Connect the new knowledge with the knowledge that has been learned and the knowledge to be learned. This is done by quickly reviewing the previous lesson and going through the topics of the next lesson before doing a new assignment.

9. Make a quick and preliminary overview of the new assignment before conducting in-depth and detailed study.

10. Try your best to explore the general mode, comprehensive structure and important rules of the new operation.

11. Try your best to write an outline of what you have learned and use the outline.

12. Give yourself concrete and rich examples of general laws and principles.

13. Emphasize the reason for learning and the purpose of learning (for what purpose to learn this knowledge).

14. When you need to review, divide the review into several times.

15. A review should take a longer time to make the most of the "preparation period", but not too long to avoid fatigue.

16. After intense studying, give a break before moving on to learning new materials.

17. Preview on the first day, intensive study on the second day, and review on the third day, which is much better than the three in a day.

18. Pay attention to obtaining information about learning progress.

19. Develop the habit of inner review, and review it immediately after learning a paragraph or section.

20. Write your own outline. The way to do this is to be your own investigator during the preview and determine for yourself what you have learned and what you need to learn further.

21. Pay attention to whether you understand and grasp the lectures, whether they are consistent with the ideas of teachers and teaching materials, improve "metacognitive ability (similar to feedback ability)", find the shortcomings of your thinking methods in time, and adjust them.

22. Whenever possible, learn an activity (skill technique) in the same way as it is used after learning it.

23. The study of particularly important content should exceed the amount of learning that can be recalled at the time (over-learning).

24. Don't rely on review alone to learn, review needs a certain purpose, "review the old and learn the new". In particular, in the study of comprehensible concepts, methods, and laws, we should strive to grasp their significance and fully apply them in the first study.

Children's shoes are good, I'm okay with chemistry, I remember a small fill-in-the-blank ...... when I took the college entrance examinationNegligence.

My approach is to read more textbooks. Chemistry is a very simple thing, and the reason why it's simple is that it's not as deep as what you learn in college, but it's high school chemistry, and one of the principles of junior high school chemistry comes from textbooks, which are slightly higher than textbooks.

So I strongly recommend, read more book knowledge, especially some short stories, many magicians are very proficient in chemistry, read more of the little knowledge in the book, as for the questions, just devote yourself to it, do more basic questions, to understand that if you don't know the basics, what should you do?80% of a test paper is basic. As for the improvement, it is recommended that you listen to the teacher in class, prepare more sticky notes, and memorize them at hand.

Grasp life, chemistry and life are also closely related.

Pay special attention to memorization. Some things are really hard to understand, but it's better to focus on the basics.

When you encounter a problem, you should connect all the knowledge points involved in it, and you may not think about it at the beginning, but stick to it, such as when you see ?c ?When you think about co, co2, co, etc., and their nature, you can't turn the page, that's how I learned.

Hey, good luck, won't ask me, look forward to your reply.

Chemistry is different from materials, it is a direct subject between science and liberal arts, and there are many things to memorize, and there are no shortcuts. When I was in high school, I used to dictate the periodic table, and it took a month to become proficient. This is very useful, not only can the questions be asked directly, but also the properties of different elements can be compared.

There are a few things that this discipline understands, but there are really not many, and the physical and chemical properties of many things have to be memorized. In particular, the reaction equations must be all proficient in the textbook. Without this foundation, you can't do any questions, so don't mention it if you want to learn it well.

First of all, you must listen carefully in class, and secondly, the homework assigned by the teacher must be completed carefully, because most of the topics assigned by the teacher are representative, and you can also do some extracurricular questions if you have the ability, but the premise is that you must complete the homework assigned by the teacher.

Third, you should mentally hint to yourself, I like chemistry, interest is the premise of learning a subject wellps: when doing the questions, you must understand them thoroughly, and when you encounter similar problems, you can be proficient in the methods you are familiar with, and the teacher should remember the teacher's methods when explaining the questions.

You need to memorize more, memorize more, and practice more.

Physics, this is a subject that I don't need to review every time I take an exam, because our homeroom teacher is a physics teacher, and he summarized a lot of questions in the process of leading us to study, and we have already done a lot of questions, so don't be afraid.

Physics is actually a few formulas and then use them in the problem, I can't say how to learn at all, because some people have asked me, I said for a long time they don't understand, but I finally said talk to your teacher, and in the end their grades really improved. What I want to say is that you should communicate your experience with the teacher in a timely manner, **No, the teacher will tell you how to learn.

The teacher's example problems in class are the most important, and a good physics teacher is to see if there will be classic examples in class. Therefore, as long as you pay attention to the explanation of the exercises in class and after class, it is OK. But it's important to do the exercises well!

Chemistry and biology textbooks are heavy, and exercises should not be too much.

There is no space in the exercises, and then look at the textbook.

Chemistry is considered a liberal arts subject in the sciences, and there are many things to memorize. But although there are many rules, the rules also have to be memorized! It's better to be the simplest, read the textbook, don't get tired of reading, the more you read, the better, if you can read it seriously 7 times a semester, the chemistry score is not high, but I must emphasize that when reading the book, you should take questions and thinks, go to read, only in this way will you understand those knowledge, I am now in my third year of high school and always hold the textbook every day to read, chemistry is still full of fun.

I have said so much nothing more than to emphasize the importance of textbooks.

Exercises are the best thing to consolidate textbooks, we should properly deal with these topics, and the amount should be more than other science subjects, after all, we have to grasp the basic knowledge, the first and second years of high school is the time to lay the foundation, if the foundation is good, the third year of high school will be very easy, so the new friends of the first and second years of high school should implement the foundation well. In addition, I still emphasize the importance of the teacher, I don't just ask him, I don't understand him.
