一般认为，基本的数字能力是更复杂的算术技能的重要组成部分。目前的研究旨在以纵向方法评估这种相互关系。本研究调查了一年级学生在一般的基本数字任务中的表现以及所涉及的具体过程（例如，位值理解）是否可靠地预测了三年级学生在加法任务中的表现。结果表明，早期的位值理解是算术表现特定方面的可靠预测因素。讨论了基本数值能力在复杂算术习得中的作用。(C) 2011 Elsevier Ltd.版权所有。
It is assumed that basic numerical competencies are important building blocks for more complex arithmetic skills. The current study aimed at evaluating this interrelation in a longitudinal approach. It was investigated whether first graders' performance in basic numerical tasks in general as well as specific processes involved (e.g., place-value understanding) reliably predicted performance in an addition task in third grade. The results indicated that early place-value understanding was a reliable predictor for specific aspects of arithmetic performance. Implications of the role of basic numerical competencies for the acquisition of complex arithmetic are discussed. (C) 2011 Elsevier Ltd. All rights reserved.
