儿童对等分概念的认知发展研究综述

摘要

Fraction, as the fundamental digital concept, is a difficult and important point in children's learning. The equal concept of dividing the whole into equal parts in fraction is the basis of the understanding and mastery of fraction. Only after the children master the equal concept can they get a clear understanding of the concept of fraction and conduct fraction computation. Focusing on children's cognitive development of equal concept, this paper makes a comprehensive study into children's cognition of the whole and part, and the equal concept, which helps to analyze children's cognitive development of equal concept and provide a theoretical basis for future research.%分数作为基本的数字概念，是儿童学习的难点和重点。分数中将整体平均分成相同几部分的等分概念，则是认识和掌握分数的基础。儿童只有先掌握等分概念，才能清楚地了解分数概念并对分数进行运算。本文针对儿童对等分概念的认知发展，从儿童对整体与部分概念的认知、对等分概念的认知等方面进行综述研究，有助于系统地分析儿童对等分概念的认知发展情况，并为以后的研究提供理论依据。
