Reading means reading the text. Students should read the next lesson word for word, find out the central problem, make clear the purpose requirements, and try to understand the basic structure of new knowledge (such as definitions, theorems, problem-solving methods, etc.). ) and make a general grasp.
Second, check
The continuity of mathematical knowledge is strong, the previous concepts are not understood, and the following courses cannot be learned. If you find that the concepts you have learned are not clear or clear in the preview process, you must refer to the relevant content before class to make it clear, and strive to leave no questions after introspection.
Third, think.
Learning begins with thinking, and thinking begins with doubt. Why ask more questions about the previewed content? From the introduction of methods to the connotation and extension of concepts, from the method of proving problems to the basis of proving problems. What are the emphases and difficulties of this section? What are the meanings of concepts, theorems and formulas? What are the conditions? How to use formulas (positive, negative, variable). There are many formulas in the math textbook. Students should temporarily put down their textbooks in preparation, think about how to deduce and compare, or compare with the teacher's deduction process in class, so as to find out whether they have made any deduction mistakes.
