本研究的目的是评估动态评估（DA；学习不熟悉的数学内容所需的支架程度）对于预测一年级计算（CA）和应用题（WP）发展的价值，同时控制传统评估的作用。 Among 184 1st graders, predictors (DA, Quantity Discrimination, Test of Mathematics Ability, language, and reasoning) were assessed near the start of 1st grade. CA 和 WP 在一年级结束时进行评估。计划回归和共性分析表明，在预测CA发展方面，数量歧视是最有力的预测因子，占解释方差的8.84%，其次是数学能力测试和DA；语言和推理并不是唯一的预测能力。相比之下，在预测 WP 发展方面，DA 是最强大的预测因子，占解释方差的 12.01%，数学能力测试、数量辨别和语言也具有独特的预测能力。结果表明，CA 与 WP 发展需要不同的认知资源，DA 可能有助于预测一年级数学发展，尤其是 WP。（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
The purpose of this study was to assess the value of dynamic assessment (DA; degree of scaffolding required to learn unfamiliar mathematics content) for predicting 1st-grade calculations (CAs) and word problems (WPs) development, while controlling for the role of traditional assessments. Among 184 1st graders, predictors (DA, Quantity Discrimination, Test of Mathematics Ability, language, and reasoning) were assessed near the start of 1st grade. CA and WP were assessed near the end of 1st grade. Planned regression and commonality analyses indicated that for forecasting CA development, Quantity Discrimination, which accounted for 8.84% of explained variance, was the single most powerful predictor, followed by Test of Mathematics Ability and DA; language and reasoning were not uniquely predictive. By contrast, for predicting WP development, DA was the single most powerful predictor, which accounted for 12.01% of explained variance, with Test of Mathematics Ability, Quantity Discrimination, and language also uniquely predictive. Results suggest that different constellations of cognitive resources are required for CA vs. WP development and that DA may be useful in predicting 1st-grade mathematics development, especially WP.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
