本研究探讨了教材中练习题的分布与学生学习十进制算术的关系。在研究一中,我们分析了十进制算术练习题在美国三种主要数学教科书中的分布情况。在3个系列中,十进制算术问题的相对频率也存在类似的不平衡:加法和减法更经常涉及2个小数,而不是整数和小数,但乘法和除法则相反。我们希望孩子们学习十进制算术能反映出这些分布偏差。在研究2,3和4中,我们测试了儿童在解决教科书中出现频率较低的问题类型时会更困难的预测,无论解决问题的内在复杂性如何。我们分析了35年前在不同实验室进行的实验(研究2),当代大规模基于网络的学习平台(研究3)以及最近在我们自己的实验室进行的对照实验(研究4)中学生的十进制算术表现。尽管3项研究之间存在许多差异,但所有3项研究的表现均与预测雅阁。这些研究结果表明,在数学教科书中的分布可能会影响孩子们做什么和不学。本文还讨论了分析教科书问题分布的合理性以及当前研究结果的教育意义。(PsycInfo数据库记录(c)2021阿帕,保留所有权利)
This study investigated relations between the distribution of practice problems in textbooks and students’ learning of decimal arithmetic. In Study 1, we analyzed the distributions of decimal arithmetic practice problems that appeared in 3 leading math textbook series in the United States. Similar imbalances in the relative frequencies of decimal arithmetic problems were present across the 3 series: Addition and subtraction more often involved 2 decimals than a whole number and a decimal, but the opposite was true for multiplication and division. We expected children’s learning of decimal arithmetic to reflect these distributional biases. In Studies 2, 3, and 4, we tested the prediction that children would have more difficulty solving types of problems that appeared less frequently in textbooks, regardless of the intrinsic complexity of solving the problems. We analyzed students’ performance on decimal arithmetic from an experiment conducted in a different lab 35 years ago (Study 2), from a contemporary large-scale web-based learning platform (Study 3), and from a recent controlled experiment conducted in our own lab (Study 4). Despite many differences among the 3 studies, performance in all 3 was in accord with the predictions. These findings suggest that the distributions of practice problems in math textbooks may influence what children do and do not learn. Usefulness of analyzing textbook problem distributions as well as educational implications of the current findings are discussed.(PsycInfo Database Record (c) 2021 APA, all rights reserved)
