分数到分式,不仅仅是整式的一种补充,它与整式一样,也是解决问题的常用工具。那么,如何引领学生走进这具有多种“承上启下”的知识体系之中呢?具体的学习不仅仅是机械灌输,也是情境引入;不仅仅是被动接受,也是自主合作;不仅仅是故步自封,也是探究延伸,以此打造坚实、多姿、高效的理想数学课堂。 Fraction to fractional, not just a whole complement, it is the same as the whole, but also a common tool to solve the problem. So, how to lead students into this knowledge system with a variety of “inheritance”? Specific learning is not only mechanical infusion, but also the introduction of context; not only passive acceptance, but also independent cooperation; not just self-styled , Is also an extension of inquiry, in order to create a solid, colorful and efficient mathematical math class.
