Physics learning methods in the second year of junior high school... What should I do if my physics

The first point is to completely change the way of learning in junior high school, from writing more and doing more to thinking and summarizing more; The learning link should be complete, not just listening to lectures and writing homework; Learn mathematics well, establish the relationship between mathematics and physics, and usually put more effort into the knowledge points of combining physics and mathematics when studying, and do more similar questions for training; Fourth, the details determine success or failure, and if the details are handled in place, the results will be on a higher level.

Physics is the study of the most general laws of the motion of matter and the basic structure of matter. As a leading discipline in the natural sciences, physics studies the most basic forms and laws of motion of all matter, from the universe to elementary particles, and thus becomes the research foundation of other natural science disciplines.

Its theoretical structure makes full use of mathematics as its working language.

Taking experiment as the only criterion for testing the correctness of theories, it is one of the most sophisticated natural science disciplines today.

Tips to improve your physics scores in the second year of junior high school:

1. Listen carefully; Listen carefully in class, and don't think or think as little as possible. Don't be self-righteous and learn from teachers with an open mind. Don't give up listening to the lecture because the teacher is simple, if this situation really happens, it can be regarded as review and consolidation.

Try to be consistent and synchronized with the teacher, and you can't do it yourself, otherwise it will be equivalent to complete self-learning. After getting started, if you have a certain foundation, you are allowed to have a certain space for your own activities, that is to say, you are allowed to have some of your own things, and the more you learn, the more you have your own things.

2. Complete the homework assigned by the teacher independently. The homework assigned by the teacher is targeted, which can repeatedly make students understand the definitions and concepts, and must be completed independently, and learn to think about physical phenomena and physical thinking methods when doing homework. Remember, don't put the cart before the horse.

3. Make the most of your time. Time is precious, and without time you can't do anything, so be careful to make the most of it, and using time is a very masterful art. For example, we can use the learning method of recall to save time, and we can recall the lessons of the day one by one before going to bed, waiting for the bus, walking on the road, etc., so that we can learn again and again, so as to achieve the purpose of reinforcement.

Some physics problems are more difficult, and some problems may have been solved by thinking of them while walking. People who study physics often have a few unmanageable questions stored in their minds, and they don't know when they will make a breakthrough and find the answer to the question.

4. Pay attention to the systematization of knowledge, pay attention to the knowledge structure, systematically grasp the knowledge structure, not memorize some definitions in your mind alone, and have a systematic concept of physics textbooks, so as to systematize the scattered knowledge. It is as large as the knowledge structure of the whole physics, as small as the knowledge structure of mechanics, and even down to the chapters, such as the knowledge structure of statics, and so on.

This kind of elastic and extended thinking will collude the entire knowledge of physics and make it easier for people to think. Only by grasping the structure of the system can we be able to solve the final problem of the synthesis and solve the difficulties.

Physics is a completely new subject for junior high school students. It is very different from the language, English, mathematics, politics, history, and geography that I have studied in the past. Not only has the content of knowledge not been covered before, but the study of law is also very different from previous subjects.

Judging from the statistics of the results of the high school entrance examination and the college entrance examination published in the past, the average score of physics is generally lower than that of other subjects, and the students' usual learning also reflects that physics is more difficult to learn than other subjects. The reason for this is that the knowledge of physics is very broad, which will be applied to various subjects such as Chinese, mathematics and even geography and chemistry.

Compared to other subjects, students often need to use logical thinking and reasoning skills. Students need to use the ideas and methods of physics to think, discover and solve problems in physics. From this point of view, the second year of junior high school students should learn physics well, and the results of other subjects are also inseparable.

If you do well in Chinese, your comprehension skills will be good, and if you are good at math, your calculation and logical reasoning skills will not be bad. As for what specific methods can be used to do physics well?

Personal advice: Be confident. If you can learn other subjects well, I believe that physics can also be studied well. It's just that you are new to physics in the second year of junior high school, and it will take a while to adapt and explore the law.

Complete your homework carefully after class and even add an appropriate amount of extracurricular homework to yourself, that is, do more questions. Because homework is the consolidation and expansion of what you have learned, if the knowledge is not consolidated and expanded, the grades will naturally not keep up, and there will be no progress in learning.

Observe more, think more. Physics is inseparable from human life and is ubiquitous, and many common life phenomena can be solved with the physics knowledge you have learned

Solids can transmit sound). Mirage (knowledge point: refraction of light).

Be attentive and patient. Science must not be hypocritical. In the same way, there is no need to be careless and careless in studying physics.

An error of a decimal point or one unit can cause immeasurable consequences and losses. For example, when you are studying the lesson "Measuring Length and Time", you need to be especially careful and patient. Because the use of various measuring instruments and reading rules, as well as the measurement results = accurate value + estimated value + unit, it seems simple, but it is easy to make mistakes, and beginners often fail in this part of the exam.

Use your hands and brains more. Physics is an experiment-based discipline, and physics experiments can help you understand knowledge and deepen your impression faster and better, so as to achieve twice the result with half the effort. Communicate more.

Communicate with the teacher more often, so that the teacher can find out your problems in time and help you solve them in time. Communicate more with your classmates, don't be ashamed to ask, maybe your classmates' opinions can make you smack. If you listen to it, you will naturally get better in physics.

Adjust your learning methods appropriately, personal advice is to have self-confidence, listen carefully in class, take good notes, complete homework carefully after class, and also appropriately increase extracurricular homework, observe and think more, and be careful and patient. In the second year of junior high school, physics is a new course, which is different from other subjects, covering a wide range of knowledge and requiring logical thinking and reasoning skills.

Yes, you should adjust your learning mode and learning mode in time, you must do a good job of pre-study, listen carefully in class, do a good job of review after class, and do more exercises.

That's how it should be. Because the learning method is not correct, it will lead to special difficulty in learning. So be sure to change your study methods, memorize more formulas, and do more exercises.

Many students in the second year of junior high school will feel very confused when they first come into contact with physics, and they don't know how to learn this subject well.

There are skills in memorizing physics.

Although physics as a science subject does not require much memorization compared to liberal arts, basic formulas, theorems, and phenomena need to be properly memorized in order to be able to integrate and cope with them in the examination room.

When memorizing, we should pay attention to finding patterns, characteristics, and accuracy. It is necessary to accurately memorize the written expressions of various definitions and laws and the "units" of various physical quantities, which is conducive to helping us form the ability to express physical words and language. One of the biggest differences between physical formulas and mathematical formulas is that each factor in the formula has a "unit".

Therefore, when memorizing the expressions of the Vertical Formula of the Object, it is important to remember the physical units of each factor.

Think more about physics.

Physics, as a natural discipline, has a very rigorous internal logic, which requires us to use our brains more and think more about the "why".

When our textbooks introduce physics concepts, laws, and formulas, they follow the steps of physics to solve problems. Generally, questions are raised first, and then carried out through experimental research, observation, analytical reasoning, generalization and other steps. Therefore, in the whole process of physics learning, while learning the problem-solving steps in the textbook, you should also pay attention to thinking to see if you can come up with experiments, methods and steps to solve the problem that are different from those in the textbook.

Practice is necessary.

When learning a new course, Ying Lishi should focus on the understanding of concepts and laws and the grasp of physical ideas, and should not rush to do a large number of exercises, and must not take the teacher's example problems and the students' exercises as the core of learning physics. Exercises should be done, but after each exercise, you should summarize it and see what new experiences you have gained in your understanding of physical concepts and laws by doing this exercise;

Check whether you can analyze the specific problems in detail, whether you can independently understand the physical state, physical process and physical situation given in the question, the causes and relevant conditions, and whether you can independently make logical reasoning. Every time you do an exercise, you should strive to improve your ability. Don't blindly pursue the number of questions, drill difficult problems, and fall into the sea of questions.

It's good to memorize all the formulas that should be memorized, brush up on more questions, and don't be afraid to ask the teacher.

Study the textbook

Everything must have an expected goal and a purpose to be achieved, otherwise you will lose the way forward, and the same is true for learning knowledge. Teenagers have a wide range of curiosity, but no amount of curiosity can replace learning goals. Each student should have a good grasp of their curiosity, transform it into a desire for knowledge, and then rationally determine the overall learning objectives of the whole semester, and make their learning process orderly according to the local learning objectives of each chapter of physics class and the detailed learning objectives of each class and each knowledge point.

Listen carefully

Genius is not born. Whether it is a new class, an experimental class, an exercise class, or a review class, every "exam champion" can make full use of the class time, listen attentively, follow the teacher's ideas, think positively, outline the key points from time to time, mark the ones that are still unclear, or record the new questions that arise, so that learning is efficient. Learning is a process, constantly spurring oneself, firm one's belief in learning, perseverance, in order to reach the realm of "learning" and "learning".

Self-inspection

Exercises are consolidation, review is systematic, and exams are tests. Every homework, every exam, complete independently, carefully review the questions, carefully calculate, refine the conclusions, think comprehensively, and standardize the answers; Correct in time, ask questions if you don't understand, learn to generalize, solve multiple problems in one question, draw inferences from one another, and unify multiple questions.

The key to learning physics well is to understand the characteristics of physics as soon as possible, otherwise, we will "take a plane", be in the clouds, be exhausted to cope, and lose the initiative to learn.

Method migration

As a beginner in physics, you will read "The Revelation of the Pendulum Story", and at the same time, you will be exposed to the use of the control variable method to study the factors that affect the period of the pendulum. Gradually, you have learned the true meaning of the method of controlling variables from experiments such as studying what factors are related to the pitch of sounds, comparing the speed and slowness of object movement, etc., and this method runs through the whole process of junior high school physics learning.
