How to learn physics, please, how to learn physics, please gods

I'm a science student, and my grades are all based on physics and chemistry. I think these two courses have a common learning method - first of all, you must have a general understanding of what you are learning from a macro perspective, that is, first you have to figure out what the teacher is talking about what it is used for and what kind of problems can be solved; In this way, you will probably know what problems you encounter and what part of the knowledge to solve. In this way, the structure and system of knowledge are clear, and it is also conducive to the understanding and learning of detailed knowledge; The next step is to carefully and carefully understand the content of the teacher, that is, to understand and memorize those formulas and theorems.

This method is suitable for me, I may wish to give you an insight, I hope it will also help you.

It depends on what kind of student you are. Junior high school? High school? Or even higher?

First of all, we must have self-confidence, believe that we will be able to learn, there is nothing difficult in the world, but I am afraid that people who have a heart will be interested in physics again, and the so-called interest is half the success.

Practical process: Preview before class, listen to class, take notes.

Note: Preview is not a simple look, after reading it, do you know what the lesson wants you to express, what kind of understanding points are required for you to master, after the class, look back on this lesson, if you have learned something, just read it again and ask again until you master it.

As far as the teaching assistant himself is concerned, I don't approve of the knowledge points, and if you master the knowledge points, you should respond to all changes with the same change, that is, you can use the knowledge points in the process to do the questions given by the teacher

The key is to be consistent with the above to ensure that you are physically OK

1. Develop the habit of pre-studying. Preview can enable you to recall previous knowledge, discover new problems, think about how to solve them, and bring problems that you can't understand to the class to better listen to the teacher's explanation. In this way, it can not only cultivate self-learning ability, but also improve the interest and effect of listening to lectures.

2. The habit of taking notes and sorting them out afterwards. As the content of the course grows and complexes, taking notes helps to get to the point. If the things you remember in class are more messy due to the tight time, then you should organize it after class to make it comprehensive and organized.

The process of sorting out is a very effective process, and it can also exercise one's ability to analyze and summarize. Therefore, you should get into the habit of organizing your notes.

3. The habit of reviewing after class. Because the pattern of forgetting is fast and then slow, what you just remember is forgotten most quickly in the first few hours, and then slower after two days. To consolidate what you have learned, you must review it in a timely manner, reinforce it, and form a habit.

4. The habit of solving problems by yourself. If you have difficulty learning, you should try to "give it a try" by yourself first. When you really can't solve it by yourself, you can complete it on your own under the guidance of your parents, taste the sweetness of victory, increase your confidence in yourself, and bravely meet the challenge of the next problem.

Learning physics is very process-oriented, a process of cognition, understanding, and application.

1.Cognition: Use the things or phenomena around you or even some examples narrated by the teacher to help yourself fully understand it and become interested in it.

2.Comprehension: Use understanding to memorize formulas, theorems, experiments, etc. It can be understood and memorized in clever ways such as visual thinking. For example, what is a vacuum can be understood in this way: a vacuum is really empty, there is nothing.

3.Application: One is to cope with the exam, and the other is to explain some physical phenomena around you.

So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself, "I can do it!! In fact, psychological suggestion is very useful!

However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it.

Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes. Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end.

Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong. How is the correct answer calculated?

Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well.

Junior high school physics is relatively not too difficult, mainly to cultivate students' perceptual understanding of physical phenomena and physical knowledge, and if you want to learn well, pay attention to the following three points:

The first is the understanding of qualitative issues. Qualitative questions are generally not required to be mastered, but you need to know the occurrence and development process of these physical phenomena.

The second is to grasp quantitative problems. Concepts such as velocity, density, solid pressure, liquid pressure, current, voltage, resistance, electrical power, etc., all need to be quantitatively calculated. Memorize and understand the formulas to solve them.

The third is the understanding of physical science. At present, the study of physics has formed a set of scientific systems, such as the concept of velocity, density, pressure, electrical power, power and so on are all in the unit (time, volume, area)...Within (through distance, mass, pressure).

to define. Knowing this kind of law can strengthen the understanding of physics and help to learn physics better.

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, and develop a good habit of writing for special calculation problems. For most questions, making drawings is quite important, the key to the circuit diagram of electricity is simplification, drawing 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 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 Practice more practice, do more exercises, physics is very interesting.

Building Confidence Materials from the front line show that the important reason why students do not learn physics well is not the intellectual factor of students. It is a lack of self-confidence, especially among girls. They often think that studying science is for boys, so they feel sorry for themselves and give up.

I have conducted research and analysis on the diagnostic examination of senior high school in Chongqing for many years, and found that the proportion of science students in the top 10 in Chongqing is usually half male and female, and in most cases there is about one more female student. This shows that learning physics is not the preserve of boys, and that there are half of girls here. In my teaching career, every class has had students who are slightly less intellectually inferior but have learned physics very well.

For example, Li Guojing, a science student in the class of 2002 (now a junior in the Department of Physics of Chongqing Normal University), did not respond quickly, but became a top science student because of his good thinking quality. Looking at students, those who learn well are confident, and those who do not learn well are often not confident. The main reason for students' low self-confidence lies with the students themselves and not with external factors.

It is true that studying physics involves mathematical troubles, verbal barriers, and lack of thinking, but these can all be overcome. The key is to believe in yourself, believe that you can do it, and you can do it. Dr. Wang Sheng, the principal of Qidong Middle School (a key middle school in Jiangsu Province), made such an experiment, and he was not a good student, but as a doctoral principal, he affirmed that he was a good student and would be successful, and he was successfully admitted to Tsinghua University.

You must know that on the long road of life, it is often not others who hinder us from moving forward, but ourselves. Low self-esteem and conceit, like twin brothers, have become stumbling blocks on the road of life. Therefore, we must learn to "accept ourselves", believe in ourselves, and the biggest challenge in life is to overcome ourselves.

For you, and for your family, give yourself a comfortable reward from time to time to make yourself the best person you can be.

Physics is actually very simple, and the most important thing is to memorize formulas! Then you should be careful in your lectures, and it is not difficult to score 80 points in the high school entrance examination.
