In order to improve academic performance, we should not only study hard, but also pay attention to learning skills and methods, so as to achieve better learning results and improve learning efficiency. 1. abbreviation. The so-called abbreviation is to compress the amount of information in memory as much as possible, and at the same time basically remember what should be remembered. Remember that the main point is not to give up other content, but to understand other content, which can greatly increase the amount of information in memory. Improve learning efficiency. This method is used in the notes of liberal arts. Second, comparative learning helps to distinguish confusing concepts and principles and deepen the understanding of knowledge. It requires us to classify knowledge according to different characteristics, and then compare and remember it. For example, the rights and obligations in political textbooks; Metaphor and metonymy in Chinese textbooks: parallelism and verticality in mathematics textbooks; Combination and decomposition in chemistry textbooks: Comparative learning method can be used not only for learning within the same discipline, but also for interdisciplinary comparison. For example, Chinese sentence analysis can be used to analyze political concepts and so on. Third, problem-based learning methods. Reading with questions helps to concentrate and clarify the purpose. It requires us to read the thinking questions after the text first, and think while reading. At the same time, we are also required to look for questions in preview, so that we can concentrate on listening when the teacher explains the questions in class; Finally, try to solve the problem in practice and don't be intimidated by the problem. The process of solving problems is the process of your progress. Fourthly, the fast reading method is not only used in Chinese reading, but also has important application value in the textbook browsing of mathematics learning. The key points of fast reading are: (1) get rid of "hidden characters" and browse quickly with your eyes to get information; (2) broaden your horizons and let your eyes get more information; ⑶ Grasp the teaching materials as a whole and get important information; (4) In the fast reading training, attention, observation and memory can be improved, so that the mind is agile, the brain is flexible, and the learners become smarter and smarter. (5) Realize "Three Grasps" 1. Grasp the attitude: you are required to concentrate and be careful in your study, to be brave in overcoming difficulties in your study, to write accurately, neatly and cleanly, and not to be "anticlimactic" or "scratch the surface". Language expression should be clear, vivid and manual, and oral recitation should be skillful. 3. Grasping ability: mainly observation, attention, memory, imagination and thinking ability. We should pay attention to cultivating these abilities in all after-school studies. To write a good composition, you can strengthen your exercise from the following aspects: 1. Careful observation is the golden key to improve our writing level. An article is the product of objective things reflected in the author's mind and mind, and it should reflect the guests.
