First of all, analyze the questions that students generally ask, that is, why can you understand in class and not do it after class? As a science teacher, I have such personal feelings: for example, reading a literary work, the description of the natural scenery and the description of the inner activities of the characters are amazing, and I know it is, but if I have to start writing, I may not be able to write the level of others. There is absolutely no problem listening to others and reading other people's articles, but it is not so easy to write them yourself and become your own things. Another example is what a child would say. If he wants to write it, he must go through repeated writing exercises to get there. Therefore, if you want to understand and do, you must practice more on the basis of understanding, so as to master the laws and mysteries and truly become your own things. This is where you should study physics hard in high school. How to work hard, what specific requirements should be met in the learning process, and what problems should be paid attention to? Let's analyze it in several levels.
Memory: In the study of high school physics, we should memorize the basic concepts, laws and some basic conclusions, which is what we often call the most basic knowledge. Students often ignore the memory of these basic concepts and think that learning physics does not need to memorize these literal things. As a result, few students, even those in cram schools, can accurately state their physical concepts in the review of senior three. I can't absolutely say that the incompleteness of physical concepts has a great influence on your study in a certain exam or a certain stage, but I can definitely say that your understanding of physical problems has an inherent adverse effect on the formation of your knowledge of the whole physical system. You can't tell which question in an exam will lose points because of your inaccurate concept. Therefore, learning Chinese requires memorizing famous sayings and epigrams, learning mathematics requires memorizing basic formulas, and learning physics requires memorizing basic concepts and laws. This is the first condition and the most basic requirement to learn physics well. Without this step, the following study is impossible.
Accumulation: it is the work after memory in the process of learning physics. On the basis of memory, we constantly collect a lot of information about physics knowledge from textbooks and reference materials, some of which come from a topic, some from an illustration of a topic, and some may come from a short reading material. In the process of collecting and sorting out, we should be good at analyzing and classifying different knowledge points, and find out similarities and differences in the process of sorting out, so as to facilitate memory. The process of accumulation is a process of struggle between memory and forgetting. However, it is necessary to make knowledge more comprehensive and systematic through repeated memory, and the relationship between formulas, theorems and laws is closer, so as to achieve the purpose of accumulation. Never repeat your homework like a bear breaking a stick, rote it and think nothing. The result will only be more memories than forgetfulness.
Synthesis: Physical knowledge is divided into chapters and sections, and the contents required by the physical examination outline are also piece by piece. They are both interrelated and different. Therefore, in the process of physics learning, we should constantly carry out small synthesis, and wait until the third grade knowledge is learned before systematically synthesizing. This process requires students' ability, and chapters are interrelated, and different chapters can be compared with each other, so that the knowledge before and after can be truly integrated, so as to gradually find the connection of knowledge from synthesis and find the interest in learning physics knowledge.
Improvement: through the memory and accumulation of previous knowledge and careful synthesis, the ability to solve problems can be improved. The so-called ability improvement, to put it bluntly, is to improve the ability to solve and analyze problems. For a certain topic, we should first look at what the problem is-mechanics, heat, electromagnetism, optics or atomic physics, and then make clear the research object, combine the conditions given in the topic, apply relevant physical concepts and laws, and also use some physical first-and second-level conclusions to get a smooth result. It is conceivable that if the basic concepts of physics are not clear, the given conditions or implied conditions in the questions can not be seen, or the formula used in solving problems is wrong or the primary and secondary conclusions should be used, but the original formula is used, the speed and correct rate of solving problems will be affected, and getting high marks in the exam will become empty talk. Improvement is first of all proficient in solving problems, then flexible in solving problems, and finally innovative in solving problems. This includes multiple solutions of the same problem, and the simplest method can be selected from the multiple solutions; It also includes multiple solutions to one problem and a method to solve multiple similar problems. Really reach the level of dexterity and ease of use.
To sum up, there are roughly six levels in learning physics, that is, understanding first, remembering later, practicing and using, gradually mastering, practice makes perfect and being brave in innovation. In the process of physics learning, according to the cognitive process from simple to complex, and comparing with six learning levels, we gradually find out our own position and level, find out our own shortcomings, and then determine our own improvement direction and efforts.
The study in senior high school is to prepare for university study, which puts forward higher requirements for students' self-study ability. The basic process of physics learning mentioned above-memory, accumulation, synthesis and improvement-is the process of cultivating their self-learning ability. They learned the learning methods, became interested in physics, and mastered the characteristics of the close combination of physics experiment discipline and practice. Through their efforts, they will certainly learn high school physics well.
As the old saying goes: Give people fish, and only have one meal. Give people fish, and you will benefit for life. Learning knowledge requires learning methods. The column of learning methods in Tsinghua Online School is composed of famous teachers with many years' teaching experience and excellent students' learning experience. The purpose is to help students develop good study habits and make them get twice the result with half the effort in their studies.
