What's the difference between physics and mathematics?
If you want to learn any course well, you must have a good learning method that suits you. This will get twice the result with half the effort. To learn physics well, we should first pay attention to the horizontal correlation of various subjects, for example, the reading ability of Chinese directly affects the learning of physical knowledge and the understanding of physical concepts; The purposeful transfer and application of mathematical knowledge in physics class is the computing ability in physics learning. Secondly, we should attach importance to the experimental science of physics, consciously and purposefully cultivate our own observation ability and experimental operation ability, as well as a scientific attitude of seeking truth from facts. Thirdly, we should attach importance to establishing the consciousness of independent thinking, analysis and summary in the process of group learning and cultivate good independent working ability. Fourth, we should pay attention to exploring the unknown areas on our own learning path, learn to explore scientifically, and rigorous analysis is the golden key to open the door to the unknown areas. Here are some suggestions on how to learn physics well in senior two. 1. Learn to use physics textbooks. What is the whole content of junior high school physics class? What parts of junior high school physics curriculum should be studied in junior high school physics class? What will the physics teacher talk about first, and then what? For a new course, students will have a series of question marks in their minds and want to know the answer. Not difficult. Every question will be answered with the learning process. The key is as a student, whether to wait for the answer passively or actively explore and find the answer, right! Do the latter, of course. At the beginning of school, every student will get textbooks for all subjects. Students in Grade Two will naturally have more physics textbooks than students in Grade One. Open the textbook, and the answers to some simple questions are in front of you. Physics textbooks are the basis for us to learn physics and the guide for students to learn physics. Students should read physics textbooks before class, learn to understand what the teacher will say in physics class, and know what to listen to in physics class, so that the learning process has a purpose. By reading physics textbooks under the guidance of teachers in class, we can achieve the purpose of recognizing knowledge and understanding the main points of knowledge. By reading physics textbooks after class, you can review and consolidate your knowledge and learn to use it to answer questions. There are a lot of words in physics textbooks to analyze and infer physical conclusions according to physical phenomena. After careful reading, students will find that these texts can not only make you understand physics knowledge in a simple way, but also make you organize the discussion language for answering physics questions, which is the language source for answering physics short questions. After we have learned some physical laws that can be written by mathematical expressions, students will read the analysis and process of solving some typical examples in physics textbooks. This is an example of solving physical computing problems. Reading well and carefully is a good process to cultivate analytical ability and comprehensive application of knowledge. This process can improve students' ability to solve physical calculation problems, master writing format and achieve natural results. There are some subheadings and small experimental topics in physics textbooks to guide students to think. You might as well read them when you are relaxing in your study time. It will make your eyes shine. Students' physical thinking will be expanded and their understanding of knowledge will be deepened. 2. Clear learning objectives and pay attention to understanding physical concepts. Everything must have the expected goal and the goal to be achieved, otherwise it will lose the direction of progress, and so will learning knowledge. The junior two students in adolescence have a wide range of curiosity, but the quantity and intensity of curiosity can not replace the learning goal. Every student should grasp his curiosity well and turn it into curiosity. Then, according to the local learning objectives of each chapter in physics class and the detailed learning objectives of each knowledge point in each lesson in peacetime, the overall learning objectives of the whole semester should be reasonably determined to make his learning process orderly. In the process of learning physics, the study of basic concepts and laws is the key and difficult point. Because the establishment of every physical concept and the cognition of every physical law need to be changed from knowing to understanding, in order to achieve the purpose of applying physical concepts and physical laws to solve problems, which can be completed in one day during the learning process. When learning every physical concept and law, students should change from "mechanical memory" to "meaningful memory" and finally rise to "logical memory". As the saying goes: the concept is clear, and it will pass once it is cleared. In other words, concept learning is the most important in knowledge learning. Therefore, in the process of learning physics knowledge, students must pay attention to the study of physical concepts in various chapters, especially to understand every physical concept and every physical law. 3. Cultivate good study habits and explore good study methods. Self-cultivation of good study habits is very important in the learning process of junior high school physics class. In the short term, you can be in a state of active learning, and in the long term, you can have the ability to continue learning independently. In junior high school physics class, students should first learn to preview and consciously cultivate preview habits. The purpose of preview is to know what to learn in the future; Make it clear which parts of the knowledge you want to learn have been basically understood and which knowledge needs to be explained by the teacher in class. Secondly, we must learn to "listen to lectures with goals and priorities", which is inseparable from preview. Only when the purpose of preview is truly achieved can the lecture be targeted and focused. Third, learn to finish your homework independently. Doing homework independently does not simply mean not copying other people's homework, but also means doing homework without referring to textbooks or class notes. It refers to the ability to complete homework independently, and it is to cultivate self-confidence in the process of students completing homework independently. While students are constantly cultivating their good study habits, they can't ignore finding excellent learning methods that suit them. The so-called good learning method should be suitable for two things: one is suitable for the subject you are studying; People who are suitable for using learning methods. Physics is a subject based on experimental phenomena, which requires students to learn to observe physical phenomena, be good at observing physical phenomena with goals, and learn to analyze and summarize according to physical phenomena combined with existing physical knowledge. The specific learning methods will vary from person to person, and every student should explore in the serious learning process. The basic principles are: learn to observe consciously and purposefully, and enrich personal perceptual knowledge; Grasp the three links of "preview, lecture and homework" that have been learned; Summarize or summarize the knowledge learned regularly. 4. Strengthen training and master basic physics skills. In the study of physics, there are two basic skills to master. One is the ability to express problems in physical terms and standardize the writing of physical formulas and problem-solving formats; The second is the basic operation ability of physical experiments. Physical language is a language tool for learning physics, so we must learn it well. Special words and symbols in physical terms need to be memorized. For example, each physical quantity has its name and letter. Every physical law or law has its clear principle. But these contents also have rules to follow. For example, the letters representing each physical quantity are mostly the first letters of English words with physical names; The statement of physical laws or laws is generally a conditional statement or a causal statement. Flexible use of the above laws, correct use of physical terms, memory of physical concepts, statement of physical phenomena or laws, no need to memorize, and no need to worry about the embarrassment of uncomfortable expression. Similarly, the writing of physical formulas and the format of solving physical calculation problems should be standardized and skilled. They are the basis of learning physics well. Physical experiment operation skills can only be mastered skillfully through a large number of hands-on experiments, and operation skills can only be found on the basis of mastery. Use both hands and brains in the experiment, follow the rules and ask yourself more questions. For every physical experiment, we should ask ourselves to understand the experimental principle, make clear the operation methods and precautions, and constantly improve our experimental operation ability and ability to distinguish experimental problems. Gradually reach the level of putting forward experimental principles, selecting experimental instruments, assembling experimental devices and designing experimental steps according to experimental topics, and drawing experimental conclusions through experimental operations. Students, I hope you can design your own physics learning process and improve your learning ability under the inspiration of the above learning methods.
