教材是数学教学的显性知识系统,许多重要的法则、公式,教材中只能看到结论;许多例题的解法,也只能看到过程的处理,而看不到实例中观察、试验、分析、归纳、抽象、概括或探索、推理的心智活动过程,学生在学习时很容易错过这些宝贵的体验,这样学到的知识往往会使智慧含量缩水。学习数学的目的“就意味着解题”(波利亚),解题关键在于找到合适的解题思路,数学思想方法就是帮助学生构建解题思路的方法。因此,向学生渗透一些基本的数学 Textbook is the explicit knowledge system of mathematics teaching, and many important laws, formulas and teaching materials can only see the conclusion; many examples of solutions can only see the process of processing, but can not see the examples of observation, test, analysis , Induction, abstraction, generalization or exploration, reasoning mental activity process, students are easy to miss these valuable experience in learning, this knowledge will often make the wisdom content shrink. The purpose of learning mathematics “means solving the problem ” (Polonia), the key is to find a solution to the problem solving ideas, mathematical thinking method is to help students build ways to solve the problem. Therefore, infiltrating some basic math into students
