The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt.

First of all, before doing all kinds of exercises, you should recall the knowledge points that the teacher said and correctly grasp the reasoning process of various formulas. If you are not clear, you should try your best to recall them instead of turning to the book immediately. Finish your homework independently and be diligent in thinking. For some problems that are difficult to solve for a while because of their unclear thinking, let yourself calm down, analyze the problems carefully and find ways to solve them by yourself.

At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system.
