家庭信息技术使用、父母网络监管与青少年认知能力研究——来自CEPS面板数据的证据

The Influence of Home Computer and Internet on Students'Cognitive Ability in the Digital Age:Empirical Research Based on CEPS Panel Data

认知能力是青少年人力资本形成的关键因素,也是其实现全面发展的基础。在当前数字化背景下,信息技术对青少年认知能力的影响值得深入探究。本文基于中国教育追踪调查(China Education Panel Survey,CEPS)基线数据(2013—2014)与追访数据(2014—2015),采用随机效应面板分位数回归方法研究了家庭信息技术使用、父母网络监管对青少年认知能力的影响,运用倾向得分匹配模型进行了稳健性检验。研究结果显示:第一,家庭信息技术的使用对青少年认知能力发展具有促进作用,但对不同认知能力水平的青少年产生了差异性影响;第二,父母网络监管对认知能力较低的青少年的认知发展呈倒U形影响;第三,青少年与父母之间的“教育期望摩擦”限制了青少年认知能力的发展。研究结论揭示了家庭信息技术使用与父母网络监管对青少年认知能力提升的重要性,对于当前教育信息化建设具有启示意义。

Cognitive ability is the key factor for the formation of teenagers'human capital,and it is also the basis for their all-round development.Under the current digital background,the influence of information technology on teenagers'cognitive ability is worth exploring deeply.Based on the baseline data(2013-2014)and follow-up data(2014-2015)of China Education Panel Survey(CEPS),this paper studies the influence of family information technology use and parental network supervision on teenagers'cognitive ability by using the random effect panel quantile regression method,and tests the robustness by using the propensity score matching model.The results show that:firstly,the use of family information technology can promote the development of teenagers'cognitive ability,but it has different efects on teenagers with different cognitive ability levels.Secondly,parental network supervision has an inverted“U”shaped influence on the cognitive development of teenagers with low cognitive ability.Thirdly,the“educational expectation friction”between teenagers and their parents limits the development of teenagers'cognitive ability.The research reveals the importance of family information technology use and parents'network supervision to the improvement of teenagers'cognitive ability,which is instructive for the current education informatization construction.
