讲座主要内容:

The unequal distribution of educational resources has been a major concern of both educators and policymakers around the world. The rise of the digital education industry brings new hope to the problem, but how exactly it affects existing education inequality remains largely unknown. Using data from a unique field experiment by an eBook app, we investigate the effects on K-12 children of improving access to digital educational resources. In particular, our analysis traces out both the short-run and long-run treatment effects of providing children with free access to digital reading resources, and how these effects vary across children with different socioeconomic backgrounds. We find that providing children with free access to digital reading materials leads to a dramatic and immediate increase in reading time for treated children, and that this immediate effect is much larger for children from less developed regions with fewer educational resources. However, children's reading activities decline quickly after the start of their free access. Surprisingly, this decline is much faster for children from less developed regions, despite their strong initial reaction to the treatment. Further evidence suggests that children from more developed regions benefit more from the free access in the long run. Our mechanism analysis further reveals a nuanced complementarity between digital and non-digital education and suggests that the long-run difference in reading patterns likely reflects differing levels of parental involvement in the education of children with different socioeconomic status. We discuss the managerial and policy implications of our study.

教育资源分配不均一直是全世界教育工作者和政策制定者关注的主要问题。数字教育产业的崛起给这个问题的解决带来了新的希望,但我们并不知道它究竟如何缓解教育不平等现状。基于一项在电子书APP上完成的田野实验,我们调查了提供数字教育资源对K-12儿童的影响。重要的是,我们的分析追踪了为儿童长期或短期提供免费数字阅读资源的不同效果,以及这些效果在不同社会经济背景的影响下是如何变化的。我们发现,为儿童提供免费的数字阅读资源显著增加了他们的阅读时间,而且这种影响对教育资源较少、经济欠发达地区的儿童来说更为显著。然而,在免费阅读活动开始后,儿童的阅读时长却迅速下降。令人惊讶的是,虽然在活动初期,来自欠发达地区的儿童的阅读时长的增长更明显;但是在后续阶段他们的阅读时长的下降速度更快。进一步的证据表明,从长远来看,来自较发达地区的儿童从免费数字教育资源中受益更多。我们的机制分析进一步揭示了数字教育和非数字教育之间微妙的互补性,并表明阅读模式的长期差异可能反映了处于不同社会经济地位的父母在教育参与程度方面的差异。最后,我们讨论了本研究的管理启示。
