How to learn physics well
Learning physics is important, and mastering the methods of learning physics is even more important. The "magic weapon" to learn physics well includes previewing, attending classes, sorting, applying (homework), reviewing and summarizing, etc. A large number of facts show that full preparation before class is the premise of learning physics well; Active and efficient lectures are the key to learning physics well; It is an important way to consolidate, deepen and activate the understanding of physical concepts and transform knowledge into the ability to solve practical problems, thus forming skills. Being good at reviewing, summarizing and summarizing can make the learned knowledge extrapolate; Reading popular science books properly and participating in scientific and technological activities are beneficial supplements to learning physics well; It is the motivation and guarantee to learn physics well to set lofty goals, make full mental preparation and maintain a good learning attitude. Pay attention to learning methods and improve learning ability. Students can start with the following points.
First of all, prepare carefully before class
Preview is an important part of reading textbooks before class and acquiring new knowledge by self-study.
To preview new lessons that have not been taught before class, we should first read the contents of the new lessons carefully, and understand the knowledge system, key points, difficulties, scope and requirements of the teaching materials through reading, analysis and thinking. For physical concepts and laws, we should grasp their core, as well as the differences and connections with other physical concepts and laws, and record the difficult problems that we don't understand in textbooks. If you forget what you have learned, you can make up for it in time when you preview before class, so that class will not be difficult. Then look at the content of the new lesson, find out the connection between knowledge points, master the context of knowledge, and draw a sketch of knowledge structure. At the same time, we should look at typical examples and find ways to solve them. It is necessary to check the reading effect by solving the exercises at the back of the book and summarize the general ideas and steps of solving the problem. Students with ability can also read extracurricular books with relevant contents appropriately.
Second, actively improve the efficiency of lectures
Listening to lectures with previewed questions can improve the efficiency of lectures and make the focus of lectures more prominent. In class, the teacher talked about what he didn't understand in the preview. He was very active, paid special attention and wanted to understand in class. At the same time, you can check the depth and breadth of your understanding of the textbook against the teacher's explanation, learn the teacher's analysis process and thinking method of difficult problems, and also ask questions, question and put forward your own views. In this way, after listening to the class, we can not only grasp the key points of knowledge, break through the difficulties and grasp the key points, but also better grasp the teachers' ideas and methods of analyzing and solving problems, and further improve their learning ability.
Third, organize your study notes regularly.
In the process of learning, through reviewing what you have learned and comparing preview notes, lecture notes, homework, standard tests, textbooks and reference books, your knowledge can reach a systematic, complete and highly summarized level. Study notes should be concise, easy to read, clear at a glance, in line with their own characteristics. Do it regularly according to the system of knowledge itself, and sort out and summarize the study notes in order to systematize the knowledge. Save the results of these thoughts in time, and when you review later, you can quickly return to the height you have reached. If you trust your memory and don't take notes while studying, you will often forget when to use it. What a pity!
Fourth, do your homework in time.
Homework is an indispensable link to learn physics knowledge well, and it is the basic method to master knowledge and skilled skills. In the usual preview, check your preview effect with the exercises in the book, and do one more question after class to analyze the optimal solution. Choose the self-test of extracurricular exercises in chapter review and give timely feedback. Therefore, doing homework carefully can deepen the understanding of what you have learned, find the weak links in knowledge and consciously strengthen them, gradually cultivate your ability to analyze and solve problems, and gradually establish confidence in solving practical problems.
To do homework well, we must first carefully examine the questions, find out the physical process described in the questions, and make clear the conditions given in the questions and the problems to be solved; According to the physical phenomenon and process stated in the question, according to the physical knowledge learned, choose the physical concepts and laws to be used in solving the problem; Establish mathematical relations through calm thinking or analytical reasoning; With the help of mathematical tools, the units of various physical quantities should be unified into the international system of units when solving; Finally, the answers must be verified and discussed to check whether the laws used are correct, whether the physical units appearing in the operation are consistent, whether the answers are correct and realistic, whether the physical meaning is clear, whether the operation process is rigorous, and whether there are other solutions. Only by verifying the answers and reviewing the problem-solving process can we firmly grasp the knowledge, be familiar with various problem-solving ideas and methods, and improve the problem-solving ability.
Review, summary and improvement of verbs (abbreviation of verb)
If you don't review the knowledge you have learned and the exercises you have done in time, and don't summarize them, it will easily lead to the fragmentation of knowledge and the tendency to learn physics in isolation and mechanically. The result must be a large piece of physical content, a lot of laws and formulas, but the specific process is not clear, and the relationship between physical quantities in the formula is not well understood. We can't focus on the overall situation and use physical concepts and laws flexibly to solve specific problems. So review and summarize in time after class. After-class review should not only organize notes, complete homework after each class, but also review chapters. We should always find out the essence, internal relations and the process of change and development of things through comparison and identification, and summarize them in time to form systematic knowledge. Through analysis, comparison, induction and summary, we can make knowledge coherent and vertical and horizontal, and deepen our understanding of physical concepts and laws from the causal relationship and development of physical quantities. This can not only consolidate and deepen the knowledge learned, but also improve the ability of induction and summary.
Sixth, make psychological preparations and adjust the learning mentality.
In the first class of studying physics, the teacher will talk about the difficulty of physics learning. Before studying physics, I heard senior students say that physics teaching is difficult. Therefore, most students have some abnormal learning mentality when studying physics, which is mainly manifested in the following aspects: (1) nervousness and fear. The difficulty in learning physics left a deep impression on their minds. They are afraid of taking physics classes, doing physics homework, asking questions in class, talking to teachers individually, doing experiments and doing things. They try their best to avoid studying. Their timid heartstrings are always tense, and they cannot combine theory with practice and apply what they have learned to practice. Over time, the more afraid they are of learning, the harder it becomes. (2) the psychology of "eating a fat man in one bite". I want to improve my grades, but after a period of hard work, my grades haven't improved much, and then I have the wrong psychology of "I can't learn well anyway" and "I'm not cut out for learning". (3) negative psychology. Learning is sloppy, lazy thinking is heavy, learning lacks initiative, and it is in a passive coping state. In class, I am often "absent-minded" and look forward to "the class will be over soon" When the teacher asks questions, most of them say "No."
It is true that physics is difficult to learn, but it is by no means bad. As long as you study according to the characteristics of physics, do as mentioned above, understand and pay attention to thinking about the physical process, don't memorize, often do things, often use your head to think, and don't ask your classmates or teachers whenever you encounter problems. If you want to find a suitable learning method and have fun in learning, you can cultivate your interest in learning physics. For example, when a student illustrates his learning ability, he makes up a jingle: "Four fixed points are action points, directions, scales and lengths, and two marks are arrows, values and units." With the development of modern society, physics plays an inestimable role. Students should take the rejuvenation of China as their own responsibility, take learning physics well to serve the motherland as their internal motivation, and realize their sense of responsibility in learning and the sense of mission in building the motherland, so as to study spontaneously, actively and actively, and will certainly learn physics well.
