Write down the questions you don't understand in class in time, so that you can ask your classmates or teachers after class and make the questions clear. When organizing classroom teaching, teachers are limited by time and space, so it is impossible to take care of every student. Therefore, some questions are difficult for some students. Because there is no time to think mature in class, write down the difficult questions, continue to think and explore after class to understand and master, and avoid the fault of knowledge and the defects of methods.

2 content outline

Most teachers have an outline when giving lectures. When giving lectures, the teacher will present the clues, key points and difficulties of a lesson on the blackboard concisely and clearly. At the same time, the teacher will make it organized and intuitive. Write down these outlines so that you can review after class, grasp the knowledge framework as a whole, and be clear and complete about what you have learned.

Three inductive summaries

Paying attention to the teacher's after-class summary is very useful for concentrating the content of a class, finding out the relationship between the key points and each part, mastering the basic concepts, formulas and theorems, finding the rules and integrating the classroom content. At the same time, many experienced teachers, when summing up after class, on the one hand inherit what they have learned, on the other hand assign preview tasks or point out what to learn later. Taking notes can master the initiative of learning, make preparations in advance, and make clear the objectives and tasks.

Four ways of thinking

The problem-solving methods and analytical ideas introduced by the teacher in class should also be recorded in time and digested after class. If you are in doubt, analyze it independently first, because it may be your own misunderstanding or the negligence of the teacher. After writing it down, it is convenient to discuss it with the teacher in time after class. Remembering the problem-solving skills, ideas and methods taught by teachers is helpful to inspire thinking, broaden horizons, develop intelligence, cultivate ability and improve the level of problem solving. On this basis, it will be more valuable if we can actively study and find another way.

5 Experience and feelings

Mathematics learning is the synthesis of intelligence, emotion, will and action. The process of mathematics learning is accompanied by positive emotional experience and will experience. Recording your feelings in the learning process can be used to better regulate your learning behavior. For example, after a complicated exercise is successfully solved by a strong will, you can write a self-encouraging sentence beside it to motivate yourself.

Six wrong ideas

It is inevitable to make mistakes of one kind or another in the learning process. Smart people don't make the same mistakes or fewer mistakes. Write down your mistakes and mark them with a red pen to warn yourself. At the same time, they should also point out the reasons for their mistakes, correct their thinking methods, mature in reflection and improve in reflection.
