What should I pay attention to in the first round of physics review in the third year of high school

Psychological preparation First of all, we must always maintain a confident attitude Self-confidence is the first prerequisite for doing a good job in the review of the third year of high school Especially students with poor foundation should be more confident, and they can lower their requirements for themselves at the beginning according to their actual situation In a round of review, you can first give up those comprehensive questions with a high starting point, a large span, and a complex process, and only grasp the basic knowledge and do basic questions Gradually improve the level, and confidence will gradually come

You must know that it is not others who can defeat yourself, but yourself. You encourage yourself every day: I can do it, I am the best.

Even if you encounter setbacks, learn from them; Even if you fail, then you think that failure is the mother of success; No matter how hard and tired you are, you think that this is "the heavens will descend on the people, and they will suffer their minds, strain their muscles and bones, and starve their bodies and skin", and they will become great things in the future. In this way, students are not only prepared to endure hardships, but also have the determination to overcome difficulties, and every day is very fulfilling, every day to think about "what I have gained", and always make themselves full of a sense of achievement, so that learning is bound to be happy, and will achieve twice the result with half the effort.

The third year of high school is a mirror, if you smile at it, it will smile at you; If you cry to it, it will cry to you. The correct mentality of every senior high school student is: laugh at the senior year.

Secondly, we must dare to face difficulties The review of the third year of high school is a systematic project, and it is inevitable to encounter some difficulties in the review, such as poor memory of concepts, poor understanding of rules, inflexible solution methods, unsatisfactory test results, etc

Be sure to pay attention to the basic knowledge points and the in-depth understanding of some concepts, and do not have to do difficult problems, it is best to do synchronous training questions.

Pay attention to the integration and classification of knowledge, try to understand each type of question, and take notes in an organized manner.

It depends on whether your physics is good or not.

1 The directional movement of the charge forms an electric current (the direction of the directional movement of free electrons in a metallic conductor is opposite to the direction of the current), and the directional movement of the positive charge is specified as the direction of the current.

2 The ammeter cannot be directly connected to the power supply.

3 Voltage is the cause of the formation of current, the safety voltage should not be higher than 36V, and the home circuit voltage should be 220V.

4 The resistance of a metal conductor increases with temperature (the higher the temperature of the glass, the smaller the resistance).

5 An object that can conduct electricity is a conductor, and an object that cannot conduct electricity is an insulator (false, "easy", "not easy").

6 Under certain conditions, conductors and insulators can be converted into each other.

Physics belongs to the sciences, but in the process of learning, it needs to be treated with the learning methods of the liberal arts. That is to say, whether it is physics or chemistry, we need more knowledge points to memorize, and secondly, we need to think about problems, and we also need to have a certain logical thinking ability and reasoning ability.

In addition to memorization, we must also learn to think, learn to learn, find a breakthrough point when doing each question, or keep up with the teacher's rhythm when the teacher is lecturing, and master our own learning methods, that is to say, when the teacher lectures, we must not only understand the questions, but also master the teacher's methods in the process of learning. At that time, one of the important reasons why I felt that I was better in science was that when I was doing the questions, I would talk to myself in the teacher's tone, that is, I would do the process while talking to myself. Well, this question is more impressive, and some breakthroughs that are easy to miss will be obvious.

Usually, when revising, start with the basic questions and try not to lose points for these basic questions. If you have spare energy, increase the difficulty, do intermediate questions, and strive for points. I won't give up on questions that are too difficult, and it would be better if I could get a score or two on the difficult questions.

Organize and classify the knowledge points (mastery, remember but not master, memory disorder, do not remember), and then arrange study and practice time one by one, and study in a targeted manner! Don't panic, keep a clear head, follow the teacher's review plan to take lecture notes, practice after class, summarize knowledge points, etc., understand the basics and master them! It is necessary to take it seriously, do a good job of making mistakes, and analyze the knowledge points and reasons for mistakes.

High school physics is really not difficult to learn, because the knowledge points of high school physics are closely connected, and the modules are neat and unscattered. Just grasp the main knowledge and string them together.

Physics is a matter of thinking. In the science comprehensive exam in the third year of high school, the score of physics is very large, and of course there are many questions. When high school students do physics problems, whether they are multiple-choice questions or big questions, they must first have the idea of solving the problem, and then they can solve the problem.

When doing a big physics problem, you must have a clear idea, and then write down each step and pay attention to the specifications.

As long as you have time, you must look at your own mistakes, remember the physical formula and master its principles, summarize the ideas for solving the problem, and if the conditions allow, you can do some to deepen your impression.

Master the relevant basic knowledge, memorize some theorem formulas, and do more relevant topics, establish a complete knowledge structure, and do a series of integrations of related knowledge.

You must brush up on the questions more, you must understand the knowledge points in the textbook, you must practice more, who will draw inferences from one another, and you must conduct more than two rounds of review.

At this time, you should review more professional knowledge points, and you should read more mistakes that you didn't know before, and memorize especially important knowledge points.

As for the question of how to review, the following two points are mentioned: First, review comprehensively and meticulously. A comprehensive review is not a simple, mechanical skimming.

A physical knowledge system composed of physical phenomena, physical concepts, and physical laws is like a big tree, with a trunk, branches, and leaves. When reviewing all the knowledge points chapter by chapter and section by section, we should pay attention to deeply understanding the internal relationship between each knowledge point, establish a knowledge structure, and equip ourselves with rich and systematic knowledge of physics, which is the basis for improving ability. My suggestion is that now is a critical period, no matter what your grades are now, this time is a critical time to sprint, or you can go to a tutorial class, and if you want to apply, you can apply for the general education course of Beijing New Oriental Middle School.

1. Basic knowledge: compulsory 12 is the foundation, almost the entire high school physics problem solving ideas and methods are established in these two books, the analysis of the motion situation, the analysis of the force situation is two important contents, and other knowledge points are added on this basis to add some new knowledge. The basics are in**?

In the textbook, so don't give up the textbook in the third year of high school review, be sure to familiarize yourself with the textbook, try to understand what every sentence said in the textbook means, and what conditions can be excavated.

2. Pay attention to listening in class, whether the teacher will or will not know the knowledge points, you must listen carefully, you will, you will compare with the teacher's ideas, see whose simplicity, whose superiority, you have to listen more carefully, and you have to continue to ask the teacher or classmates after the class if you don't understand it thoroughly!

3. In most cases, the solution method of high school physics test questions is relatively unified, and the mode is relatively simple.

4. The problem we need to pay attention to is that almost all physical problems can only be solved by listing equations, so we must strive to find out the equivalence relationship according to the conditions given in the problem, and list the equations to solve the problem.

5. Physics formulas, theorems, laws and general processing methods are like the rules of the game, if you are not familiar with the rules of the game, how can you apply the high school physics test game with ease?

The above is my own opinion on learning high school physics, and I would like to ask you to add the shortcomings!

To get the knowledge done, you have to build a physical model in your mind, like a bullet hitting a wooden block, a conveyor belt, and so on.

The basics, the content of the book.
