First, remember the outline of the content.
Most teachers have an outline in their lectures. When giving lectures, they will present the clues, key points and difficulties of a lesson on the blackboard concisely and clearly, and at the same time, they will be 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.
Second, remember the problem.
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.
Third, remember the way of thinking.
The problem-solving methods and analytical ideas introduced by the teacher in class should also be recorded in time. Digest it after class. If in doubt, analyze it independently first, because it may be your own misunderstanding or the teacher's negligence. 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 and cultivate ability, and also help to improve the problem-solving level. On this basis, it will be even more valuable if we can actively study and find another way.
Fourth, remember to sum up.
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.
Fifth, remember feelings.
Mathematics learning is the synthesis of intelligence, emotion, will and action, and the process of mathematics learning is accompanied by positive emotional experience and will experience. Writing down your feelings in the learning process can be used to better control your learning behavior.
For example, after a complicated exercise is successfully solved by a strong will, you can write down self-encouraging sentences such as "Good things are more grinding" to motivate yourself.
