一、问题的提出中学数学是一门较成熟的公理化了的学科.它的内容抽象、逻辑严谨,创造过程中的面貌往往不易察见,教材结构呈演绎特征,其突出表现在其中一系列的“规定”.数学中的所有定义是规定的,数学符号是前人制定的,数学名词是约定俗成的,数学公理是规定的,不加证明的,甚至许多数学法则、书写格式等也是有相应的规定.研究表明:数学中这一系列的规定是学生感到数学抽象难懂的原因之一;再加上一些教师教学时处理不得法,认为 First, the problem raised Middle school mathematics is a more mature axiomatic disciplines.Its content is abstract, logical rigor, the face of the creation process is often not easy to see, the textbook structure was a deductive feature, which is highlighted in one of a series of Mathematical rules are established by predecessors, mathematical terms are conventions, mathematical axioms are prescribed, without proof, and even many mathematical rules, writing formats, etc. are also There are corresponding provisions.Research shows that: This series of rules in mathematics is one of the reasons why students find it difficult to understand math abstraction.
