To learn college physics well, we should do the following:
First, preview carefully before class is an important link to read the teaching materials independently and acquire new knowledge by yourself before class. To preview the 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 the textbook. 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 read the typical examples and try to solve them. We should check the reading effect by solving the exercises after the book, and sum up the general ideas and steps of solving problems. Preview before class can make you know the content to be introduced in class in advance, so that you can be targeted when listening to the class. Mark what you don't understand in the preview and go to class with questions; For the content that has been understood, you can listen to the class with an exploratory point of view to see whether the teacher's analysis method is consistent with your understanding, whether there are any omissions, how to analyze the same problem from different aspects, how to establish the physical model, and so on. Adequate preview will make you get twice the result with half the effort.
Second, take notes. As the saying goes, "A good memory is not as good as a bad writing."
You should remember the teacher's explanation of various concepts, definitions, symbols in formulas, the meanings of formulas and the application conditions in class. You should write down what you didn't understand in the preview, not what is already in the book. Only in this way can you gain something from listening to the class.
Third, after-school review After-school review is an important link to digest and absorb what you have learned and turn it into your own knowledge. Be diligent in thinking, and state the new concepts, definitions, symbols in the formula and the meaning of the formula itself in your own language. For the proof of theorems and the derivation of formulas that should be mastered, it is best to work them out with books and notes on your back after understanding the basic ideas. Only in this way can you have a deep understanding of their conditions, key steps, deduction skills and mathematical knowledge that should be mastered.
Fourth, finishing homework in time is an indispensable link to learn physics knowledge well, and it is the basic method to master knowledge and skills. In the usual preview, check your preview effect with the exercises in the book, and do more exercises to solve one problem and analyze the optimal solution when doing homework after class. Select the self-test of extracurricular exercises in chapter review and give feedback in time. Therefore, doing homework carefully can deepen the understanding of what you have learned, find the weak links in your 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, select the physical concepts and laws to be used in solving the problem according to the learned physical knowledge; After calm thinking or analytical reasoning, establish mathematical relations;
