集合是现代数学最基本的概念之一,是幼儿学习计数的基础。幼儿认数是从感知和比较集合开始的。所谓集合,就是“具有某种特征(条件)的单个事物所组成的整体”或“具有一定特征的单独物体所组成的整体”。苏联幼儿教育家列乌申娜在《学前儿童数概念的形成》一书中从心理学的角度作了这样的描述:“我们将不同分析器感受的同类对象(物体或现象、声音、运动等等)的总体叫做集合。”从以上观点归纳起米看,集合有两个特点:一是,一类事物的全体,而不是个别;二是,集合所包括的事物是确定的,以某些共同特征为条件。
Set is one of the most basic concepts of modern mathematics, is the basis for counting children learning. Toddler recognition begins with perception and comparison sets. The so-called set, is “a certain feature (condition) composed of a single thing” or “a certain feature of a separate body consisting of a whole.” The Soviet Union early childhood educator Le Ursina in the “preschool children’s concept of the formation of” a book from the psychology point of view made the following description: “We will be different analyzer feel the same kind of objects (objects or phenomena, sound, exercise, etc. Etc.) is generally called a collection. ”From the point of view of rice summarized from the above point of view, there are two characteristics of a collection: one is the entirety of one kind of thing, not the individual; the other is that the things included in the collection are definite, Common features as conditions.
