Computational estimation is seen as an important mathematical competence. Little is known, however, about the mathematical skills that are predictive of early computational estimation development. The current study longitudinally followed a group of about 350 children at four time points: second (K2, 4-year-olds) and third grades of kindergarten (K3, 5-year-olds) and first (P1, 6-year-olds) and second (P2, 7-year-olds) grades of primary school. The computational estimation task was administered in two variants: a nonverbal variant, in which the problems were presented with manipulatives and children also answered using manipulatives was administered in K3 and P1; and a verbal variant, in which the problems were presented with Arabic numerals and children had to answer verbally was administered in P1 and P2. Furthermore, children’s basic numerical skills and exact and approximate arithmetic skills were assessed in K2 and K3, respectively. Path analysis showed a positive autoregressive relationship between the verbal variants of the computational estimation task but not between the nonverbal ones. Basic numerical skills were important predictors for computational estimation at all time points. Approximate arithmetic positively contributed to nonverbal estimation, while exact arithmetic positively predicted verbal estimation. In sum, solid basic numerical and arithmetic skills support children when performing computational estimation. Future intervention research should further unravel the causal contribution of each of these basic numerical and arithmetic skills.

哪些技能可以预测计算量?对5至7岁儿童的纵向研究

计算估计被视为重要的数学能力。然而,关于预测早期计算估计发展的数学技能知之甚少。当前的研究在四个时间点纵向跟踪了大约350名儿童:四岁(K2,4岁)和三年级幼儿园(K3,5岁)和一年级(P1,6岁)。 )和小学二年级(P2,7岁)。计算估计任务有两个变体进行管理:非语言变体,其中问题由操作性表示,并且还使用操作性回答的儿童在K3和P1中进行管理;还有一个语言变体,其中问题用阿拉伯数字表示,而儿童必须口头回答的问题在P1和P2中进行。此外,在K2和K3中分别评估了儿童的基本数字技能以及精确和近似的算术技能。路径分析显示了计算估计任务的语言变体之间的正自回归关系,而不是非语言变化之间的正自回归关系。基本的数字技能是在所有时间点进行计算估计的重要预测指标。近似算术积极地促进了非语言估计,而精确算术积极地促进了言语估计。总而言之,扎实的基本数字和算术技能可以在进行计算估计时为孩子提供支持。未来的干预研究应进一步阐明这些基本数字和算术技能的因果关系。路径分析显示了计算估计任务的语言变体之间的正自回归关系,而不是非语言变化之间的正自回归关系。基本的数字技能是在所有时间点进行计算估计的重要预测指标。近似算术积极地促进了非语言估计,而精确算术积极地促进了言语估计。总而言之,扎实的基本数字和算术技能可以在进行计算估计时为孩子提供支持。未来的干预研究应进一步阐明这些基本数字和算术技能的因果关系。路径分析显示了计算估计任务的语言变体之间的正自回归关系,而不是非语言变化之间的正自回归关系。基本的数字技能是在所有时间点进行计算估计的重要预测指标。近似算术积极地促进了非语言估计,而精确算术积极地促进了言语估计。总而言之,扎实的基本数字和算术技能可以在进行计算估计时为孩子提供支持。未来的干预研究应进一步阐明这些基本数字和算术技能的因果关系。基本的数字技能是在所有时间点进行计算估计的重要预测指标。近似算术积极地促进了非语言估计,而精确算术积极地预测了言语估计。总而言之,扎实的基本数字和算术技能可以在进行计算估计时为孩子提供支持。未来的干预研究应进一步阐明这些基本数字和算术技能的因果关系。基本的数字技能是在所有时间点进行计算估计的重要预测指标。近似算术积极地促进了非语言估计,而精确算术积极地预测了言语估计。总而言之,扎实的基本数字和算术技能可以在进行计算估计时为孩子提供支持。未来的干预研究应进一步阐明这些基本数字和算术技能的因果关系。
