(2) Do the problem independently. Do some problems independently with good quality and quantity (meaning not relying on others). There must be a certain number of topics, not too few, but also a certain quality, that is to say, there must be some difficulty. Anyone who studies mathematics and physics can't learn this level well. Solving problems independently may sometimes be slow, sometimes you have to take detours, and sometimes you can't even solve them, but these are normal and the only way for any beginner to succeed.
(3) Physical process. To clarify the physical process, there must be hidden dangers in solving problems if the physical process is not clear. No matter how difficult the topic is, try to draw as much as possible, some can draw sketches, and some need to draw accurate pictures, using compasses, triangles, protractors and so on. To represent geometric relationships. Drawing can turn abstract thinking into image thinking and master physical process more accurately. With this diagram, we can make state analysis and dynamic analysis. State analysis is fixed, dead and discontinuous, while dynamic analysis is alive and continuous.
(4) attending classes. Listen carefully in class, don't be distracted or try to be less distracted. Don't be self-righteous, learn from the teacher modestly. Don't give up listening just because the teacher speaks simply. If this 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 self-study. After getting started, with a certain foundation, you are allowed to have your own activity space, that is, you are allowed to have something of your own. The more you learn, the more things you have.
(5) Notebook (corrected version). Class is mainly based on listening, and there are notebooks, and some things should be written down. Knowledge structure, good problem-solving methods, good examples, places you don't understand, etc. Should be recorded. After class, you should organize your notes. On the one hand, you should "digest" and on the other hand, you should supplement your notes. Notebook is not only to remember what the teacher said in class, but also to make some reading notes. Good problems found in homework and good solutions should also be recorded in a notebook, which is what students often call a "good problem book". Hard-won notebooks should be numbered, studied later and kept for life.
(6) learning materials. Learning materials should be well preserved, classified and marked. The classification of learning materials includes exercises, papers, experimental reports and so on. Marking refers to, for example, marking exercises. General questions are not marked. Good questions, valuable questions and error-prone questions are marked differently for future reading. Marking can save a lot of time.
(7) time. Time is precious. Without time, there is no time to do anything, so we should pay attention to making full use of time, which is a very superb art. For example, we can save time by "recalling" learning methods. Before going to bed, waiting for the bus, walking on the road, etc. We can recall the lessons of the day section by section, so that we can learn them again and again and achieve the goal of strengthening. Some physics problems are more difficult, and some problems may be solved on foot. People who study physics often have several problems in their minds that they can't do and won't forget. I don't know when they will make a breakthrough and find the answer to the question.
(8) learn from others. We should learn from others, from our classmates, from people around us and see how others learn. We should often have "academic" exchanges with them, teach each other, learn from each other and improve together. We must never be self-righteous. Cann't be conservative Tell others if you have a good method, so that others will tell you that you have a good method. You should have some good friends in your study.
(9) Knowledge structure. We should attach importance to the knowledge structure, master it systematically, and systematize scattered knowledge. From the whole knowledge structure of physics to the knowledge structure of mechanics, even to chapters, such as the knowledge structure of statics and so on.
(10) Mathematics. The calculation of physics depends on mathematics, which is too important for learning physics. Physics is difficult to do without mathematics as a calculation tool. In the physics department of the university, mathematics and physics are equally important. To learn mathematics well, we must make good use of this powerful tool.
(1 1) Sports activities. Healthy body is the guarantee of good study, and vigorous energy is the guarantee of high efficiency in study. You should always take part in sports activities, know one or two kinds of exercise methods, take part in sports activities all your life, and do sports activities continuously. Just because you are interested in fishing for three days and drying the net for two days, it will not do much good to your health. Consciously exercise. To ensure adequate sleep, it is not advisable to increase study time by reducing sleep time. You can't get some good grades at the expense of overdraft health, you can't talk about the so-called "sprint" and "struggle" at every turn, and you should pay attention to the regularity in your study, that is to say, you should always work hard and don't engage in surprise attacks.
Specific practices:
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.
