Abstract
Berkowitz et al. (Reports, 9 October 2015, p. 196) described a randomized field experiment testing whether a math app designed to increase parent-child interaction could also bring academic benefits. A reanalysis of the data suggests that this well-designed trial failed to find strong evidence for the efficacy of the intervention. In particular, there was no significant effect of the intervention on math performance.
摘要
伯科威茨等人（报告，2015 年 10 月 9 日，第 196 页）描述了一项随机现场试验，旨在测试一款旨在增加亲子互动的数学应用程序是否也能带来学术益处。对数据的重新分析表明，这项精心设计的试验未能找到干预措施有效性的有力证据。特别是，干预对数学表现没有显著影响。
