长期以来,人们普遍认为幼儿数概念的获得是从计数开始的。这种看法实际上并不全面,幼儿早在数数以前就已经有了对少量物体的模糊数量观念,这其实就是对集合的笼统感知。幼儿从对集合的笼统感知到学会计数、掌握初步的数概念,其中要经历一个中间环节,这就是对集合的确切感知和用对应的方法比较集合中的元素,这个过渡环节正是幼儿形成初步数概念的必要基础。许多实验研究结果表明,从感知集合入手,对幼儿学会计数,理解数的实际意义,学习运算和促进幼儿初步的抽象概括能力的发展有着显著的效果。幼儿在日常生活中会经常看到成人把同类的事物归 For a long time, it is generally accepted that the concept of early childhood is obtained from the count. In fact, this view is not comprehensive. Toddlers already had the concept of fuzzy numbers of small objects as early as their own. This is actually a general perception of the collection. Children from the general perception of the collection to learn the count, grasp the preliminary concept of several, which go through an intermediate link, which is the exact perception of the collection and the corresponding method to compare elements in the collection, the transition is precisely the formation of early childhood The necessary basis for the concept of numbers. Many experimental studies have shown that starting from the perception set, it has a significant effect on the counting of young children, understanding the practical significance of numbers, learning and computing, and promoting the development of early abstract abilities of young children. Young children often see adults in their daily lives to the same kind of things
