Abstract

This study’s purpose was to examine the effects of the concrete-representational-abstract integrated (CRA-I) sequence on the performance of students who struggled with rational number concepts. Three students in fifth grade participated in the study. The CRA-I intervention was grounded in the principles of explicit instruction and showed rational number concepts related to fractions and decimals using fraction blocks, number lines, base 10 blocks, and coins. Students learned about unit fractions, fraction magnitude, fraction equivalence, addition of fractions with unlike denominators, equivalent decimals, and notation of fractions as decimals. The researchers used a multiple probe across behaviors design and demonstrated a functional relation between CRA-I and three behaviors: decreased fraction estimation error, accuracy in adding fractions with unlike denominators, and accuracy writing fractions as decimals.

向数学学习有困难的五年级学生教授有理数概念

本研究旨在考察具体-表象-抽象综合（CRA-I）序列对有理数概念学习有困难的学生的影响。三名五年级学生参与了研究。CRA-I 干预以显性教学原则为基础，使用分数积木、数线、10 基数积木和硬币展示了与分数和小数有关的有理数概念。学生们学习了单位分数、分数大小、分数等价、分母不相同的分数加法、等价小数以及分数记作小数。研究人员采用了跨行为的多重探究设计，并证明了 CRA-I 与三种行为之间的功能关系：分数估计错误的减少、分母不相同的分数加法的准确性以及将分数写成小数的准确性。
