“集合论”是近代数学的基础,应用十分广泛。目前中学已讲授集合论部分知识,集合的思想更是渗透到中小学数学教材中。让学生扎实地掌握“集合论”的基本概念、基本思想,是中学教师应十分注意的课题。本文试图在集合论基础知识教学上作些探讨,而不涉及较深理论。一、注意讲透集合的基本含义和思想集合是集合理论的奠基概念。什么叫集合呢?这是首先必须回答的问题。凭借人们的生活经验,直观感觉可以判,全体中国人是 “Set theory ” is the basis of modern mathematics, is widely used. At present, high school has taught part of the theory of set theory, and the idea of ​​assembly is to permeate the textbooks for primary and middle schools. It is an issue that should be paid great attention to by middle school teachers so that students can master the basic concepts and basic ideas of “theory of set theory.” This article attempts to make some discussions on the basic teaching of set theory without involving deeper theories.
