How to learn physics well in senior high school? In addition to the innate factors of small probability, there is indeed a learning method problem here. Who doesn't want to be a good student? But if you want to be a really good student, you must first build your self-confidence. No matter what my starting point is, I will climb bravely. It's too low. I will try to correct it. In addition, to dare to endure hardships means to cherish time, to study tirelessly, to firmly believe that you can learn any course well, to firmly believe in the "law of conservation of energy transformation", and to firmly believe that you have made some contributions, you should have some gains. Please read the following three quotations about this article: I never believe in any innate or acquired talent, and I can succeed without firm and long-term efforts. Dickens (British writer) The main reason why some people can far surpass others is not so much genius as his indomitable spirit of concentrating on his studies and never giving up until he reaches his goal. -Dalton (British chemist) The fastest and slowest, longest and shortest, most common and most precious, most easily overlooked and most regrettable thing in the world is time. -Gorky (Soviet writer) The first thing mentioned above should be said to be the problem of learning attitude and thinking method. The second is to understand that there are eight links in learning as a student: making a plan → previewing before class → concentrating in class → reviewing in time → working independently → solving problems → systematically summarizing → studying after class. The most important thing here is: concentrate in class → review in time → work independently → solve problems → summarize systematically. In the above eight links, there are many learning methods. According to the characteristics of physics and how to learn physics well, this paper puts forward several specific learning methods. (1) Sanji. Basic concepts should be clear, basic laws should be familiar, and basic methods should be skilled. Give an example about the basic concept. Like speed. It has two meanings: one is to express speed; The second is the ratio of distance to time (such as in uniform circular motion), and the speed is the ratio of displacement to time (in uniform linear motion). There are two formulas for calculating basic laws, such as average speed, V=s/t and V=(vo+vt)/2. The former is a defined formula, which is applicable to any situation, while the latter is a derived formula, which is only applicable to the case of uniform linear motion. First of all, the basic methods commonly used to study middle school problems, such as holism and isolation, are typical supplementary methods. Finally, another question belongs to three basic problems. That is, in the process of learning physics, we sum up some concise and practical inferences or conclusions, which are very useful for solving problems and learning physics well. For example, "the potential decreases along the electric field line"; "The tension on the same rope is equal"; "Maximum speed at zero acceleration"; "Lorentz force does not do work" and so on. 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 stored, 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. (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.
How to learn physics well in senior high school? Physics focuses on understanding, which is consolidated by doing problems. First of all, we should try our best to thoroughly understand what the teacher is doing in class, and then do some exercises. Be sure to do it yourself. If you don't understand it, go to the textbook, because you must have forgotten what the textbook is about. If you know what the textbook is about, you will associate the rules with the chapters of the topic when you can't do the problem. Can I use this topic? At first, you will gradually change one by one. You don't have to set it deliberately, you will think about the laws that can be used. The key content of high school physics is not much, force and motion: there is a Newton 3 law, momentum, kinetic energy and energy, which can be obtained by mastering half of physics, and then electricity: mainly experimental circuit analysis. Be sure to pay attention to your own work when you are in Grade One and Grade Two, and then remember 4 to 5 laws. How's the heat? You just need to remember the concepts, and you will have no problem if you remember these questions well.
In short, you should think more about physics. Doing the problem is just to help, you really get it. Doing the problem is just to help you practice your speed in order to cope with the college entrance examination.
How can we learn physics well in senior high school? If you don't understand, you should ask. Teachers and classmates can ask. Don't be afraid of losing face and don't ask for answers. Most seemingly complicated problems are considered in the conservation of energy. Besides, we really need to do more exercise. I think we also have a physics paper a day when we take the college entrance examination. In addition to understanding, speed is also important. Pay attention to others' simple answers. Answer to the point, don't write so many words, not even words. Are all formula steps. There is nothing you can do about the formula, so you must understand it. If you forget, just look at the encyclopedia of physical formulas (most teachers have summaries). To some extent, we can skip the obvious problems and encounter more problems. The tactic of challenging the sea is the way to become a master.
How can we learn physics well in senior high school? A lot of physics in senior high school focuses on understanding. To find a way, sound and light, heat and electricity are five pieces, and photoelectricity is relatively difficult, especially electromagnetism. There are many things to remember, so we should learn to use them flexibly, do more exercises and learn to sum up. I wish you good grades ~
What's the difference between 89 1 college physics and 92 1 college physics? This is the hierarchical teaching of college physics, and the division standards of different schools are slightly different, but they are roughly as follows:
Grade A: I have a good foundation in physics and mathematics, like studying physics, have a good understanding and understanding of the basic concepts, principles and laws of physics, and can be skillfully applied to solving practical problems, which can meet the requirements stipulated in the national college physics teaching syllabus.
Grade B: Good foundation in physics and mathematics, moderate achievement in mathematics, like physics study, and can basically master the basic concepts, principles, laws and applications of physics. Through hard work, it can basically meet the requirements stipulated in the national college physics teaching syllabus.
Grade C: All students except Grade A and Grade B, these students have low math scores, are afraid of difficulties in learning physics courses, can basically understand the general basic concepts, principles and laws of physics, have the ability to solve practical problems initially, and can basically meet the minimum requirements stipulated in the syllabus through hard work.
Implementing hierarchical teaching is a very important link. Its guiding ideology is to change the traditional exam-oriented education into quality education. The principle of hierarchical teaching is to organize teaching according to different basic teaching requirements without reducing the teaching quality and completing the outline tasks. The purpose of hierarchical teaching is not to artificially create grades, but to help them improve their academic performance by adopting different methods.
How to learn college physics well without high school physics foundation? Learning physics pays great attention to the process, a process of cognition, understanding and application.
1. Cognition: Use things or phenomena around you or even some examples described by the teacher to help you fully understand it and get interested in it.
2. Understanding: memorizing formulas, theorems, experiments, etc. In an understanding way. You can use clever methods such as thinking in images to understand and remember. For example, what is a vacuum can be understood as follows: the vacuum is really empty and there is nothing left.
3. Application: one is to cope with exams, and the other is to explain some physical phenomena around you.
So when studying, don't be afraid at first, because the experience you didn't learn well before may imply something, which may lead to a vicious circle. Trying to tell yourself "I can do it" is actually very useful! However, in order to increase your confidence, you'd better prepare well and know what you are doing.
Secondly, in class, we should follow the teacher's thinking closely, take some notes appropriately, and remember some knowledge points that are not clearly stated or even omitted in the book and are easy to make mistakes. Take more time to practice after class, and don't shirk it for any reason, thus giving up the best period of practice, which will only lead to tragedy in the end.
