First of all, learn to preview. It is very important to preview mathematics, because all the knowledge we haven't talked about will be related to the knowledge we have learned before, and because many formula theorems are derived from the previous knowledge, we must make clear the origin of formula theorems in the preview process, so that preview can drive the review of previous knowledge points. Remember, if we just look at it, it means that there is no preview, let alone review.
2. Classroom information absorption rate
A western philosopher said that choice is the golden key to the art of listening. This is very suitable for classroom listening. Generally speaking, teachers should listen to everything they say, but sometimes teachers will take different ways to talk about different levels of content in order to take care of students at different levels. At this time, students should listen selectively according to their own actual situation, that is, grasp the key content that is of great significance to them. Every teacher has a certain way of thinking in class, and following the teacher's ideas can achieve good learning results. So, how to grasp the teacher's thinking when listening to the class? Grasp the teacher's thinking according to his prepared logical structure. In most cases, teachers' lectures are based on the knowledge structure of the textbook itself. If you compare the logical structure of knowledge you have understood when preparing for the exam with the structure explained by the teacher, you can grasp the key points. According to the teacher's prompt, grasp the teacher's thinking. Teachers often use some hints in teaching, such as "Please pay attention", "I repeat" and "The key to this problem is ……". Pay attention to what the teacher emphasizes, which is often the focus or difficulty of this class. Following the deduction process of the teacher, when the teacher teaches a conclusion in class, there is usually a deduction process, such as the ins and outs of some formulas in mathematics. According to the questions in class, grasp the teacher's thinking. Teachers often ask some questions in the course of lectures, some require answers, and some ask themselves and answer themselves. Generally speaking, the questions raised by the teacher in class are the key. If we can grasp the teacher's questions and think deeply, we can grasp the teacher's ideas. You must walk in front of the teacher in class. You should not only follow the teacher's thinking, but also try to walk in front of the teacher. For example, as soon as the teacher asks a question, you should take the initiative to find the answer and then check it with the teacher's answer. If you think it's right, the teacher will remember it more firmly when he speaks again; I can't think of it, or it's different from the teacher's answer. Listen to the teacher's explanation again, and my understanding will be deeper.
