回归课本（The return of textbooks） The return of textbooks The return of textbooks A lot of guidance materials proposed to return to the textbook, I do not agree with this formulation, the so-called regression shows the time away from the textbooks. I advocate Gang Gang, in this the. The pro forma review stage can not leave the textbooks. I claim that at least three books. Every time the focus is different, the first time is very fine, look carefully from the preface, introduction, text and unit are examples of, theorem proving, formula should be repeated several times. Second the textbook ordering up, re integration, form their own knowledge system. The integration should be the combination of abstract and concrete, general and special combination of basic knowledge and exercise combined with approximate analysis of concept and formula, find out the similarities and differences between them. The third is the memory. Now focus on the second. (a) the combination of abstract and concrete. A learning function concept to clear two non empty set, which is the elements of the set must be a number. The real problem is the practical problem, must be to establish the mathematical model of digital. Two to clear the function of the three elements (high two elements) in the combination of abstract and concrete. The system of mathematics in the original concepts and axioms, to establish the concept (definition) then the theorem and formula (theorem proving, formula derivation). The characteristics of mathematics is highly abstract, the abstract from concrete, therefore, to understand the concept must be returned to the specific. As the concept of function which is the basic concept of modern mathematics. Philosophy tells us that things in the world, is not isolated, static, but is associated with movement. All things have the quality and quantity of both sides. The amount of describing things The first is the relationship between the domain is determined by correspondence or law. Pay
