Find out how to learn physics and math essays well in junior high school

To learn physics well, you must observe more, and look at no physics problem with a questioning eye, there are many concepts to remember, and after learning each lesson, you must also remember to summarize, including exams, it doesn't matter if you don't take the test, you have to sum up your experience. The summary is the most important, including the summary of the classroom teacher, the summary of the self-preview review after class, the summary of the wrong questions, it is best to find a book, record the experience, and usually turn over more, For the formula, the memory also needs to be understood, and the appropriate use is used according to the specific situation, and the scope of application of the formula is noted. Don't equate physics with mathematics, especially calculate problems to develop a good habit of writing format.

For most problems, it is quite important to make diagrams, the key to the circuit diagram of electricity is to simplify, draw so that we can distinguish the connection situation at a glance, the force analysis of mechanics is the basis of the problem, the optical path diagram can help us analyze the problem, and even the boiling evaporation of heat will be used in the diagram Of course, it is easier said than done, but there is no pressure I think the key to junior high school physics is to get started, and the touch class will be bypassed to connect more with reality and do more exercises.

If it's an essay, it's really difficult, after all, I like to be concise. So I'll mention a few of my experiences. In fact, you don't have to work hard to do problems in physics, but the teacher must listen to the class, and the notes will be useful to you and easy to understand, in fact, if you always want to take good notes in class, you will not have the energy to listen carefully to what the teacher is saying, or you can take notes in class and do it directly in the book, and the same is true for mathematics.

I think about how I was often the first in the school in physics, so I really didn't have to work as hard as their so-called nerds.

First, learning must be forward-looking.

That is, you know what the teacher will talk about in this lesson before the teacher starts the class, and then you have to skim through the corresponding chapters at a glance. For example, if the teacher talks about the chapter on quadratic functions, then before the teacher gives a lecture, we should first open the table of contents of the book and look at this chapter, which mainly talks about "the relationship described by quadratic functions, getting acquainted with parabolas, braking distances and quadratic functions, the image of quadratic functions y ax2 bx c, using quadratic functions to solve the problem of maximum profit and maximum area, quadratic functions and unary quadratic equations". I have a general impression in my heart.

2. Correct habits of listening to lectures.

Mathematics and physics, unlike liberal arts knowledge, cannot relax attention all the time when listening to lectures, which is especially important for doing big questions, because it is very likely that a knowledge point will be missed in class, and a big question will not be answered. You must have a good habit when listening to the class, unless the teacher is completely knowledgeable to explain, otherwise, especially when the teacher explains the topic, you must hold a pen in your hand, you can mark down the important places that the teacher has talked about, you can calculate the topics you don't understand again, or you can calculate it on the scratch paper yourself before the teacher explains.

3. Correct learning attitude.

You must enjoy the class from the bottom of your heart, and you should not have a rebellious mentality. This is a matter of learning attitude, and it is also the key to learning well in the classroom.

Fourth, timely consolidation and practice.

The purpose of the exercises is to acquire the knowledge and to be able to do all the questions in this type of question. For the topics of homework after class, we should try to increase the speed as much as possible, and the topics that we don't know how to do should be "thinking - turning the textbook - thinking - finding teachers and classmates - thinking again", a lot of knowledge and skills in science are easy to forget after we do it, I think we must firmly grasp the knowledge and problem-solving skills, and the questions we have done must be repeated once or twice.

In mathematics, I think that I should do more typical exercises, remember to write down the typical exercises to a correction book, the teacher has been emphasizing this at the time, but I have never understood the concept, and the exercises in the textbook are also very important. There's nothing else.,Physics, I think the important thing is the formula and the concept.,After the teacher has talked about it, you have to push the formula on one side by yourself.,On the premise that the teacher has talked about it, you have to push it yourself.,The junior high school physics formula is the most important.,The second is the concept.,Physics, you also get an error correction book.,I don't know how your foundation of these two subjects is.,When I went to school, I felt that these two subjects were not difficult, especially that physics was simple.,Later, I went to high school.,I thought the physics teacher told us about junior high school physics, which is not called physics., At best, it is popular science knowledge. I'm a freshman now, so I guess I can't go too far.

Hehe, you can use these suggestions, I hope your grades are getting better and better!!

First of all, you must listen to the lecture well and memorize the formulas clearly, but not rote memorization, you must be familiar with the application. After each question, if you feel that the classics are classic, you should think more about them, and come up with your own feelings, you should have an experience of how excited you are when you come up with a difficult problem. Also, communicate with good classmates to make progress together, and at the same time promote friendship, the best of both worlds.

The most important thing is for you to develop an interest in physics and mathematics, interest is the most important thing!! Then it's best to preview before class, listen carefully in class, do homework after class, remember that homework must keep up, in fact, physics and mathematics are similar, science subjects, you need to experience with your heart, do the problem with your heart, and then experience the fun of learning in the topic, believe you can do it, come on!

There are two things you have to do now:

The first thing is to make up for what I didn't learn before. Anyone can fall behind in their studies, and it's normal to encounter such a situation. There are two options for you to choose from:

The first is to take out the books that you haven't learned well before, and the questions you haven't done before and re-learn and do them again. The second is to use the follow-up lessons to pull the previous lessons. For example, if you learn plane geometry, you don't learn triangles well, and when you do a topic about circles, you may encounter something that you can't afford because you don't know the previous knowledge, at this time, we can turn out the previous book to see that part or think about why by ourselves, but stop here and don't systematically review the previous content.

The second thing is to change your study habits. For example, if you do the question yourself, if you have a question, you won't be able to look at the answer and turn it over if you understand it, you will at least have to do it again independently, and it is best to think about why you thought of this question and did it. If you can do that, after a while, you will find that different chapters of mathematics have different types of problems, but they all have a unified mathematical idea behind them.

Your foundation is too weak, lay a solid foundation first, let your grades be slightly better, so that you can be a little confident, and then go all out and make a tutoring material seriously, first pick the knowledge points you don't know to do, break each one, and then do the whole set of questions. As long as you want to learn well, you will definitely improve.

Wrong too. No matter what you learn, the most important thing is "interest" in the first place. Gu Leng, your understanding is very good, and you are only in the second year of junior high school, so you have a lot of time, and now you can make up for it.

First of all, you have to make sure that you spend a lot of time (at least 1 hour) in science every day, and it must be voluntary, with interest, and when you solve a problem, that indescribable joy will make you feel confident and interested. Then everything is easy to do, listen carefully to the class, and do your homework. There are still questions that you must understand on the same day, it is best to think about it yourself, use your own strength to solve this problem, think that your head hurts before you can ask other students, and, don't be afraid, learn more with the math masters in your class, and learn well in a team, complement each other!

It's a good idea to have a math class on the weekends that suits you. Believe me, you're absolutely right. Remember, interest is the most important thing.

Haha, you're right.

The last thing I worry about is math and physics.

To be good at mathematics and physics, the key is to understand it well in class, do more example problems, and draw inferences from others

Ask more!

Be sure to keep in mind the definition of physical quantities. Also understand the formula. Do more questions, and do the exercises after class first. Do something simple that is helpful for understanding physical quantities.

Brain-working, especially physics, is entirely based on IQ.

First of all, adjust your own methods, don't have a rejection mentality, be interested in these two courses, and try to make up for the knowledge you didn't know before. In physics, you should memorize the formulas, analyze the actual problem, think clearly about the possible situations, be careful when calculating, and the most important thing is the method.

Although everyone says that the sea of questions tactic is not advocated, it is indeed the most effective, do more questions, kid.

In class, you should listen carefully, do more, practice more, be good at independent thinking, don't be discouraged, have confidence, be calm in the face of problems, and believe in yourself.

Do more questions, there is no other way!

Mathematics: The most important thing in mathematics is to master the method, to know the test point when you get a question, to prescribe the right medicine, to think diligently, and to ask why. To really understand why you can't do it half-heartedly.

English: memorize more articles to practice the sense of language, carry a vocabulary book with you, and memorize words physics when you have time: pay attention to problem-solving ideas, ask questions frequently, think more, communicate more with teachers and classmates, junior high school physics is simple, and usually listen carefully to the lectures.

I'll tell you something that is more suitable for junior high school First, ask more teachers, this trick is king!!

Language: Chinese pays great attention to accumulation, this lesson is more special, not to say how you work hard to achieve good results, to continue to accumulate and is a long-term accumulation! How to learn Chinese well in junior high school?

Accumulate!!! Usually buy some exercises to do: ancient texts modern texts If you can arrange time, you can also buy ancient poems (if you train now, it will be very beneficial for you in high school, because ancient poems are very important in high school), in the process of doing it, you must accumulate books, ancient texts are the accumulation of word meaning, of course, the textbooks should also be paid attention to, and there are broken sentences to be cooked; As for modern literature, it is some methods of answering questions, such as artistic techniques, expression techniques, etc., etc., etc., and the teacher may have a summary for you at that time, and you yourself must also accumulate and then memorize some famous books.

Mathematics: Classes are very important, that is, to listen carefully You should listen a lot of things like this, but that's the way it is, listening carefully is not as simple as not talking and not deserting I used to think like this, but then I found out that I was wrong to know that I had to follow the idea of thinking only when I knew how to think in the first year of high school Summarized as: Follow the teacher's train of thought The teacher is one step faster than the teacher when he talks about the topic The teacher has to turn his mind desperately when teaching knowledge points These three simple sentences It took me three years to summarize these three simple sentences!!

I hope you cherish it! And you have to experience it for yourself!! The above is to listen to the class, usually to do more questions, must do more, math class should be on every day, of course, homework must be completed, every night in addition to homework to buy practice to do (this is a high score method), of course, you only complete the homework usually listen carefully to the class can also get good grades Remember three words:

Brush Brush Brush! English: Like Chinese, it is also a long-term accumulation I usually buy some reading, cloze and picture and word practice, and some common new words need to be accumulated in a notebook, which is miserable, right??? There's no way this can be like this, and you'll know it when you're in high school, and there's a lot of new words in an article, and you don't even know what the four options of cloze ABCD mean.

One thing to pay attention to here is not to look up every word, you must learn to guess the meaning, if it is too difficult, skip the space and read the whole article to understand his meaning. The notes must be read, it is best to read early, the importance of early reading I also did not realize until the third year of junior high school, because the test points of the individual items in the exam are all from the textbook, and there is another point, you should have three minutes before class to read the text or words, right? Must read!

There are still words to memorize, and I think the worst thing is to memorize words, but you also have to memorize them.

Old forget! Do more questions, boys, you won't be able to do questions Brush brush! Also, you should always draw pictures and mark the known quantities, these teachers should have told you.

In mathematics, first of all, you must listen carefully in class, and distinguish between the key and non-key points of what the teacher says. Secondly, do more exercises, distinguish the intention of the questioner, understand its method, master a variety of ideas, and ask questions if you don't understand, and you must spend more effort.

Junior high school physics is mainly formulas, understand the meaning of each formula, not many questions, to be fine, understand the idea of each question, follow the teacher in class, take more notes, exercises, it is definitely not a problem.

Learn with your heart, dear As long as you put your heart into it, you will definitely learn well.

Just memorize the basic formula and do some questions.

I think:

1.First of all, you should be interested in the subject of physics, and you should think that it is very easy!That's a piece of cake for me!

2.Then do a good job of pre-study and after-class exercises, that is the foundation, I want to emphasize that when listening to the lecture, listen to the key points, and then write down (to write down what you think is important, and finally sort it out).

3.Finally, put together what you think is related, and compare the similarities and differences (which is important!!
