集合是数学的一个重要概念,它不仅跟高中数学的绝大部分内容都有联系,更在于集合思想当今已经渗透到自然科学的各个领域.因此让学生掌握集合知识不仅是数学教学本身的需要,同时也是提高学生素质的需要.由于集合这一节教材概念较抽象,出现的符号术语比较多,致使部分学生一时难以适应,解题中 Set is an important concept of mathematics, it is not only with most of the content of high school mathematics are linked, but also that set theory has now penetrated into all fields of natural science.So let students master the knowledge of assembly is not only the need of mathematics teaching itself, But also to improve the quality of students .As a result of the collection of textbooks in this section more abstract concepts, there are more symbolic terms, resulting in some students difficult to adapt to a temporary problem-solving
