Mathematics is a subject that tests logical thinking and is full of theory. If you want to learn mathematics well, you need unremitting efforts, and students need to think repeatedly and keep learning. Then, for junior high school students, how can the guidance of junior high school mathematics be efficient?

First, do a good job in preview.

Different from primary school mathematics, junior high school mathematics pays more attention to improving students' mathematics-related abilities, such as self-study, problem analysis and abstract thinking. The learning difficulty is also increasing, from the previous concept of equations to the range of functions. When dealing with these math problems, we might as well preview them in advance. In the excellent education, their teacher taught a preview method, that is, from extensive reading to intensive reading.

Intensive reading is mainly to understand concepts, formulas, theorems and so on. And try to answer some simple questions related to the preview content and test your preview results. If you don't understand anything, bring it to class to listen to the teacher's explanation, and the class will be more purposeful.

Second, consolidate the review in time.

I don't know if you have heard of forgetting curve, which refers to the law of forgetting new things in the human brain. As time goes on, people's memory of one thing will gradually decline. Therefore, in order to improve our memory of mathematics, we can consolidate and review our knowledge of mathematics in time, and understand our mastery of knowledge through related topics. If we have forgotten and weak knowledge, we can also strengthen our study.

Although the difficulty of junior high school mathematics has changed qualitatively, as long as we master the methods, I believe everyone can learn mathematics well and achieve satisfactory results.
