Preview is the process of actively acquiring new knowledge, which helps to mobilize the initiative of learning. Before explaining new knowledge, it is an important means to read the teaching materials carefully and develop the habit of previewing actively.

Therefore, we should pay attention to cultivating self-study ability and learn to read books. For example, if you teach yourself an example, you should find out what the example is about, what the conditions are, what you want, how to answer it in the book, why you answer it like this, whether there is a new solution and what the steps are.

Grasp these important problems, think with your head, go deep step by step, and learn to use existing knowledge to explore new knowledge independently.

Active thinking

Many students just listen and can't think actively in the process of listening, so when they encounter practical problems, they don't know how to apply what they have learned to answer them.

The main reason is that you didn't consider the trouble caused in class. In addition to following the teacher's thinking, we should also think more about why we define it like this, and what are the benefits of solving problems like this. Taking the initiative to think can not only make us listen more carefully, but also stimulate our interest in some knowledge and help us learn more.

Rely on the teacher's guidance to think about the way to solve the problem; The answer is really not important; What matters is the method!
