After a decade of correlational research, this study is the first to measure the causal impact of (general) smartphone use on educational performance. To this end, we merge survey data on general smartphone use, exogenous predictors of this use, and other drivers of academic success with the exam scores of first-year students at two Belgian universities. The resulting data are analysed with instrumental variable estimation techniques. A one-standard-deviation increase in daily smartphone use yields a decrease in average exam scores of about one point (out of 20). When relying on ordinary least squares estimations, the magnitude of this effect is substantially underestimated.

智能手机使用和学习成绩:相关还是因果关系?

经过十年的相关研究,这项研究是第一个衡量(一般)智能手机使用对教育绩效的因果影响的研究。为此,我们将关于一般智能手机使用的调查数据、这种使用的外生预测因素以及学业成功的其他驱动因素与两所比利时大学一年级学生的考试成绩相结合。使用工具变量估计技术分析所得数据。每日智能手机使用量每增加一个标准差,平均考试成绩就会下降约 1 分(满分 20 分)。当依赖普通最小二乘估计时,这种影响的大小被大大低估了。
