High school physics is a very troublesome subject for many senior students. Complicated formulas and complex question types. If you want to learn physics well in the third year of senior high school, you should grasp the first review stage of senior high school. Let's share some ideas about how to improve your physics performance in the third year of senior high school. I hope it will help you.
Pay attention to the review of basic knowledge
Senior three students want to improve their physics performance, first of all, they need to review the basic knowledge of physics, and review at regular intervals, so that they can quickly and effectively improve their physics performance. Many senior three students often study day and night, and their academic performance may be very good, but this method is not suitable for everyone, so, Learning physics also needs to master a suitable one, so as to maximize the efficiency of improving physical performance.
In fact, learning about is an understanding of physics learning ideas and a mastery of physics, so that we can understand the learning skills of physics. Only in this way can we find a learning method of our own. If you use the spare time every day to study physics or other subjects, the effect on improving your performance will be very significant. Learning will also get twice the result with half the effort, making it easier to use memory to review physical knowledge.
Do more representative exercises
In the training of physics problem solving, many senior three students just blindly pursue the amount of problem solving. In fact, if they want to improve their physics performance, the effect of doing problem solving naval warfare is not obvious. They should do more representative and selected topics, which will significantly improve their ability to understand and apply physics knowledge. If they can thoroughly understand some typical problems in physics, And it can draw inferences from other cases, which is a kind of improvement of physics learning. It is not difficult to improve physics performance. In addition, we should also summarize the knowledge points in the textbook.
Sort out wrong physics questions
When doing exercises in physics, it is inevitable that there will be some mistakes. These mistakes are also a key point to improve the performance of physics learning. If you want to improve the performance of physics learning, you should sort out these mistakes, understand them thoroughly, and review these recorded mistakes more. It is also a very good way to improve the performance of physics in senior three.
Attach importance to the classroom
The first thing is to accept and like your physics teacher. The rejection of the teacher will inevitably affect the learning of the subject. The third year of senior high school is dominated by review lessons. Under the pressure of the college entrance examination, many students will choose to immerse themselves in exercises and give up listening.
But Mr. Gao believes that even if the review lesson is about the knowledge learned, we should correct our attitude and listen carefully. After all, the teacher reviewed the contents of the three years in a few months, and what he said must be the essence.
In the review, the teacher's teaching mainly focuses on classic problems and difficult problems, and seldom involves specific knowledge points. These topics themselves are worth listening to. On the other hand, other students are still listening to the lecture during one round of review. But you start to practice exercises. Will you be tired of it when everyone focuses on the second or third round of review?
Refine Notes
Physics notes must be refined. Note refining can not only save valuable time, but also facilitate searching and review. However, the notes should still be recorded in sections, such as error prone warnings, secondary conclusions, history of physics, etc; For electrical experiments, electromagnetic induction and other parts, those who should draw in the notes should not be lazy. There is no need to copy all the wrong questions. Summarize one question in one sentence. First classify the knowledge of the wrong question and then refine the cause of the error. When reviewing, one sentence can associate with relevant questions and knowledge points.
About Scrolling Questions
Scrolling questions is not equal to the tactics of "question sea". What is worth doing is the questions with high quality and strong comprehensiveness. In terms of difficulty, basic questions need to be practiced, but the amount is not too large. The accuracy of exercises in ordinary times needs to be above the college entrance examination, and higher than the opponent to defeat the enemy. Multiple choice questions have huge scores. Physics requires high scores. Multiple choice questions must be all right. You can use spare time to practice a lot. In the three rounds of review, it is inevitable that there will be a sense of fatigue. If you are upset when you see a big question at this time, practice more multiple-choice questions and focus on the big question when you are energetic. Don't force yourself to change subjects when you really can't keep up.
1. In the process of brushing questions, we must pay attention to that the number of questions is not too many, and the quality is excellent.
There is no need to have too many exercises. You can really do one exercise well, and others can be used as snacks other than staple food, and you can choose some exercises to do. What I said is to do well in the exercise is to know not only the nature, but also the reason, so that you can stand in the perspective of the author to see what knowledge points the topic examines and how these knowledge points are connected, Later, when encountering such problems, we will know how to start, and where to start is easier. This is the real way to do the problem.
2. Pay attention to the accumulation of wrong questions.
Students who can spare no effort in learning can also consider making a separate physics problem book or a complete set of physics problem books. It is really important to brush more problems in physics. Practice makes perfect is an eternal truth, so don't just memorize the formula. The key is to use more of what you have learned to solve problems, I believe everyone knows how to accumulate ideas and skills to solve problems in practice.
3. Summarize
The most important thing in the first round of review of physics is, of course, to go through all the knowledge points learned in high school with the teacher in a down-to-earth way. We should go from some basic concepts and theorems to the formulas of kinematics, mechanics, momentum, energy, electromagnetics, and then to the derivation of some common formulas, As well as some common thinking skills when doing questions can be slowly summarized in the first round of review
4. Choose the right method
In particular, we need to pay attention to the applicable conditions of the formulas and theorems that we ignored in the first and second stages of senior high school, because later you will find that the same two methods can solve problems, but at this time you often do not know when to use what formula, such as a problem that can be solved by the kinetic formula and the momentum energy point of view, If you take the appropriate method, you will get twice the result with half the effort. Another method may take a page of grass paper to calculate the result. It is very important to choose the most appropriate ladder method at this time
5. Pay attention to the extensibility of the basic formula.
Many of them can be directly deduced and memorized. At this time, we'd better write them down. For example, in the chapter of gravity, the basic formula is a law of gravity, but combined with the kinematic formula, we can deduce the secondary formula to directly calculate the mass and density of celestial bodies. Although these secondary formulas can be temporarily deduced by ourselves during the exam, But it is more useful for us to take a little time to write it down, which can greatly save the time for problem solving.
6. Write at the end
I emphasize again that the purpose of the next round of review of physics for the college entrance examination is that we have an overall grasp of the examination points of physics for the college entrance examination. At this stage, the most important thing is to lay down the basic knowledge of each knowledge module. At this time, we must pay attention to the details of basic knowledge, pay more attention to the in-depth understanding and mining of basic knowledge concepts, and pay attention to the applicable conditions of theorems, formulas, etc, We can classify knowledge, such as conservation of energy, conservation of charge, etc. The law of universal gravitation and coulomb law can be fully analogized, and then we can compare the differences in the application conditions of the kinetic energy theorem and the momentum theorem, so as to prepare for two rounds of training on the fusion of knowledge points, so that we can make a qualitative leap in the second round of review and even in the third round of sprint, The scores reflected on the paper will look better.
