【摘要】：探讨中国儿童数字估计的表征模式与发展趋势。包括两个实验,均采用数字线估计任务,实验一以92名幼儿园、一年级及二年级儿童为被试,考察其在0~100范围的数字估计,结果显示,幼儿园儿童在数字估计更多地采用对数表征,而一二年级的儿童在数字估计中更多地采用线性表征;实验二以86名一、三、五年级儿童为被试,考察其在0~1000范围的数字估计,结果显示,一年级儿童有一半采用对数表征,另一半采用线性表征,而三五年级儿童大多采用线性表征。中国儿童的数字估计表现出与美国儿童相同的发展模式,都是由不精确的对数表征逐步向精确的线性表征发展;人的数表征有多种形式,即使在同一年龄阶段,也会因任务难度的不同而选择不同的表征模式。中国儿童精确数字估计能力的出现要早于美国儿童。
[Abstract]:To explore the representation model and development trend of Chinese children's digital estimation.Including two experiments, the task of digital line estimation was used. In experiment one, 92 children in kindergarten, first grade and second grade were taken as subjects, and their numerical estimation in the range of 0 ~ 100 was investigated. The results showed that,Children in kindergarten use logarithmic representation more in digital estimation, while children in grade one and two use linear representation in digital estimation. Experiment two takes 86 children in grades one, three and five as subjects, and examines their numerical estimates in the range of 01000.The results showed that half of the first grade children used logarithmic representation, the other half used linear representation, while the third and fifth grade children mostly used linear representation.The numerical estimation of Chinese children shows the same development pattern as American children, which is gradually moving from imprecise logarithmic representation to precise linear representation. The representation of human numbers has many forms, even at the same age.Different representation modes will also be chosen according to the difficulty of the task.Chinese children's ability to estimate accurate numbers is earlier than that of American children.
