1. Pay attention to regular study (1) and study textbooks. The army does not fight unprepared battles, and so does learning physics. I hope you can pick up your physics textbook, open a picturesque chapter, follow the table of contents and get a general idea of the content of this semester. Preview each chapter before each class. You have a lot of doubts, waiting to solve the mystery with the teacher in class. When reviewing, the textbook should be reviewed repeatedly. "Read it a hundred times, and the meaning will appear." Every time, new discoveries will be made. (2) Listen carefully. Genius is not born. Whether it's a new class, an experimental class, a problem-solving class or a review class, every "examination champion" can make full use of class time, concentrate on listening, keep up with the teacher's ideas, think positively, sketch out key points from time to time, mark unclear ones, or record new questions, so that learning will be efficient. Learning is a process. Only by constantly pushing ourselves and strengthening our learning beliefs and perseverance can we reach the realm of "learning" and "learning". (3) self-monitoring. Practice is consolidation, review is system, and examination is testing. Every homework, every exam, completed independently, carefully examined the questions, carefully calculated, refined conclusions, comprehensively thought and standardized answers; Revise it in time, ask if you don't understand, learn to sum up, solve more than one question, draw inferences from one example and ask more than one question. To learn physics well, the key problem is to understand the characteristics of physics as soon as possible, otherwise you will be "flying", confused, at a loss, and lose the initiative to learn. 2. Pay attention to the physical process (1). For example, the teacher pricks several small holes with different heights beside an empty mineral water bottle and pours the water into the bottle. Keep your eyes wide open, just like watching a movie, for fear of missing something. Do the experiment well. The teacher asked what was observed. The collective answer is "water gushes out". In fact, there is another answer, "the smaller the hole below, the farther the water is sprayed." Two phenomena, two conclusions, and the latter is the focus of research. Physics is a subject that focuses on observation and experiment. There are many physical experiments in junior high school, but the experiments are not fun. (2) I can think. What are the two phenomena in the above example? Looking back on the previous knowledge, the wooden block presses on the sea surface and the sponge presses down, indicating that the wooden block has pressure on the sponge. For example, when water comes out, it means that water has pressure on the side wall of the bottle, and the deeper the water, the greater the pressure. So what happens if you pour other liquids? "There are doubts in the heart, small doubts and small progress, big doubts and great progress." Only by thinking with the brain can we realize the sublimation of thinking. (3) will explore. The above is an introductory course to learn the law of liquid pressure. If you want to study in depth, you need to explore in groups. It is very important to prepare enough experimental equipment, design control variables during the experiment, distinguish several rows and columns when compiling data tables, clarify the division of labor among team members, and communicate and cooperate. 4 can talk. "Say" means "induction". According to the measured data, horizontal and vertical comparison, summarize the experimental conclusion. What data can be quantitatively compared to draw a preliminary conclusion? How to process the data and draw further conclusions? When drawing a preliminary conclusion, the language narrative should be refined, and attention should be paid to the control variables and the integrity of the conclusion. When drawing further conclusions, we should understand that the operations of addition (sum), subtraction (difference), multiplication (product) and division (ratio) are to get new physical concepts, which are essentially different from ordinary mathematical operations. There is no process in learning physics, just like building a building without foundation, which is unstable. Can only recite concepts, but can't use them. After a long time, those physical terms, formulas and principles have become "holy books", but they are not "true classics" if I don't understand them. 3. Pay attention to the method transfer of thinking methods (1). As a beginner of physics, you will read the enlightenment from the story of a simple pendulum, and at the same time, you will be exposed for the first time to "study the factors that affect the period of a simple pendulum" with the method of controlled variables. Gradually, you have mastered the true meaning of the control variable method from the experiments such as "What factors are related to the tone of sound" and "Comparing the speed of object movement", and this method has been used throughout junior high school physics learning. It can be said that if you master this method, your junior high school physics study will be half successful. Learn the law of light propagation, and the teacher teaches you to draw light to show the path and direction of light propagation. Is there really "light" Of course not, only "light" has no "line", which is physically fictitious for the convenience of research. Knowing this, you will know that the "magnetic induction line", "particle" and "electric field line" in high school are also "building physical models". The story of Cao Chong calling an elephant has spread to this day, and Cao Chong skillfully used the physical idea of "equivalent replacement". The gravity of the stone placed on the boat is equal to the gravity of the elephant, which "breaks the whole into parts" and solves the problem that there are no big names. Concepts such as "resultant force" and "total resistance" are also used in this way. The image of "distance-time" in junior middle school physics is the basis of learning the image of sports mechanics and other images in senior middle school. Junior high school physics lays the foundation for senior high school physics and college physics, so you should also learn the following research methods: accumulation method, analogy method, comparison method, induction method, image method, list method and so on. (2) Knowledge transfer. Physics curriculum system is divided into five parts: mechanics, heat, optics, acoustics and electricity. Except for the relative independence of optics, other contents are inseparable whole, and matter, motion and energy bind them together firmly. We should grasp the physics textbook as a whole, make clear the position of knowledge in this unit, this textbook and the knowledge system, and pay attention to the connection before and after. 4. Pay attention to the application of knowledge physics. If it comes from life, it is necessary to return to life and learn to use physical knowledge to solve practical problems in study, life and production. (1) brought back to life. Will you be as scared as you were when you were a child when there was a sudden power outage at home? Maybe the fuse is blown. Go and have a look. /kloc-in the 0/00 meter race, why did you ask the timekeeper to start timing when you saw the gun smoking, instead of hearing the gunshot? You already know that the speed of light is much greater than the speed of sound. Just do the math. Why do cars have to travel a long distance after braking? How to reduce traffic accidents when roads are slippery in rainy and snowy weather? This is related to inertia and friction. How to judge whether a ring is pure gold? Measure the mass and volume, calculate the density, and check the density table for comparison! With the deepening of physics study, you will suddenly understand that life is full of physical puzzles, waiting for you to solve them. (2) Extracurricular research. The material world is real and rich. Guess what kind of world there would be without sound? The fantasy article "Silent World" was immediately released. With the modernization of the city, the buildings with glass walls are getting higher and higher, and the night is getting brighter and brighter. The dazzling lights have brought a lot of inconvenience to residents' lives. Then think about how to reduce light pollution. "If there is no friction", "Physics on Bicycle" ... investigation report, extracurricular production and extracurricular exploration can extend physics from one class to another, bringing you joy and surprise in research. (3) interdisciplinary. The allusions of "carving a boat for a sword" and "stealing a clock" contain profound physical principles: reference objects, relativity of motion and static, generation and spread of sound. China's ancient poems, idioms and proverbs describe many physical phenomena. We can learn relevant physics knowledge from Chinese people and appreciate the excellent quality of physicists from history. When you have tasted the pleasure of using physical knowledge to solve practical problems, you will happily and actively devote yourself to the study of physical knowledge. 5. Pay attention to the cooperation of emotional input (1). People are not independent individuals and cannot exist without groups. Some physical problems can't be fully answered by thinking alone, and collective wisdom is needed at this time. Some experiments cannot be operated by one person, and two or even four people need to work together to complete them. Sometimes the answers are varied and need to be discussed collectively to find the truth. (2) insist. Study hard in physics. Einstein said, "Success is one minute of genius and ninety-nine minutes of sweat". Learning physics requires thinking. Archimedes said, "Give me a fulcrum and a lever long enough, and I can move the earth." . Be modest in studying physics. Newton said, "If I see farther than others, it is because I stand on the shoulders of giants". "Diligence is good at diligence, poverty is good at play, success is good at thinking, and destruction is random." Learning physics must be down-to-earth, lay a solid foundation, master systematically, step by step, and don't make a surprise attack.
