简单枚举是不完全归纳推理的一种,是以对某类事物部分对象的判断作为前提,由此推出关于某类事物全体对象的判断。限于小学生思维发展水平,抽象数学概念常常是学习中的难点,也不宜采用严格意义上属加种差的方法来定义概念,通过简单枚举可以帮助学生抽象概念的内涵、明晰概念的外延,从而化解理解概念的难题。 Simple enumeration is not a kind of incomplete inductive reasoning, based on the judgment of some objects of certain kind of things as a prerequisite, thus the judgment of all the objects of certain kinds of things is deduced. Limited to the level of thinking of primary school students, the concept of abstract mathematics is often difficult to learn, but also not strictly use the method of adding species to define the concept of a simple enumeration can help students abstract the concept of connotation, the concept of explicit extension Solve the problem of understanding the concept.
