小学数学课本中众多的数学基础知识,包括基本的概念、计算的法则、重要的结论等等,往往通过枚举归纳概括(又称“不完全归纳”)得出.枚举归纳概括,与小学数学教材,教法和小学生的认知特征水乳交融,以致不易觉察它的独特价值和探究的必要. The basic knowledge of mathematics in elementary school mathematics textbooks, including basic concepts, laws of calculations, important conclusions, etc., are often drawn through enumeration and generalization (also called “incomplete induction”). Enumeration generalization, and elementary school The mathematics teaching materials, teaching methods and the cognitive characteristics of the pupils are well-coordinated, so that it is difficult to perceive its unique value and the necessity of inquiry.
