摘　　要：本研究以115名4~5岁幼儿为研究对象,探讨幼儿非符号数量表征、数轴估计和计算流畅性的关系。结果发现,幼儿非符号数量表征、计算流畅性和数轴估计之间呈显著正相关;计算流畅性在幼儿非符号数量表征与数轴估计关系中起中介作用;计算流畅性水平高的幼儿使用较优数轴估计策略的人数显著高于计算流畅性水平低的幼儿,且前者数轴估计的精确性也明显优于后者。研究者据此提出相关建议。Taking 115 children aged 4-5 as research subject,this paper explores the relationship among children's non-symbolic numerical representation,number line estimation and calculation fluency.The results show that there is significant positive correlation between non-symbolic numerical representation,number line estimation,and calculation fluency.Calculation fluency plays the mediating role in the relationship between non-symbolic numerical and number line estimation;when using better strategies,children with high level of calculation fluency far outnumber that of children with low level of calculation estimation,and the accuracy of the first group of children is also much better than that of the second group of children.The authors provide some suggestions.
