家庭和学校数字化学习资源投入对学生数字素养的影响机制研究

The Influence Mechanism of Digital Learning Resource Investment at Home and School on Students'Digital Literacy

基于我国东中西7省24个市(区、县)的11797名小学生和初中生的调查数据,探究家校数字化学习资源投入对学生数字素养的影响机制。结果表明:家庭和学校数字化学习资源均能显著正向影响学生数字素养,其中家庭数字化学习资源和家庭背景的贡献份额较高。通过异质性分析发现,增加家庭和学校数字化学习资源投入均能显著提升城乡学生的数字素养水平;家庭和学校数字化学习资源投入对数字意识和数字社会责任的提升效应呈现下降趋势,对计算思维和数字化学习与创新的提升效应呈现倒U型;家庭和学校数字化资源的影响均存在单门槛效应。通过机制分析表明,家庭和学校数字化学习资源投入均可以通过先前数字化学习经历间接对数字素养产生正向影响。基于这些发现,提出以下建议:数字化学习资源投入应从“学校”拓展到“家庭”,既要发挥家校互补作用,弥补城乡学生数字素养差距,又要发挥家校协同作用,实现数字化学习资源对数字素养“意识层”和“技能层”的差异化效用,同时也要丰富学生数字化学习经验,并加强后续评估,促进学生数字素养的持续提升。

This study explores the impact mechanism of digital learning resources on students'digital literacy from the perspective of home-school collaboration based on survey data from 11,797 primary and middle school students in 7 provinces across eastern,central,and western regions of China.The results indicate that both family and school digital learning resources significantly and positively influence students'digital literacy,with family digital learning resources and family background contributing more significantly.Moreover,the results of the heterogeneity analysis discover that increasing investment in digital learning resources at both home and school can significantly enhance the digital literacy levels of students in urban and rural areas.Quantile regression results reveal a decreasing trend in the effects of family and school digital learning resources on digital awareness and digital social responsibility,and an inverted U-shaped trend for the effects on computational thinking and digital learning and innovation.Additionally,both family and school digital resources exhibit a single-threshold effect on digital literacy.Furthermore,both family and school digital learning resources indirectly influence digital literacy through previous digital learning experiences.Based on these findings,the following suggestions are proposed:(1)to expand digital learning resource investment from“schools”to“families”to leverage the complementary advantages of home and school resources,bridge the urban-rural digital literacy gap,and synergize home-school collaboration to achieve differentiated effects on the“awareness”and“skills”dimensions of digital literacy;(2)to enrich students'digital learning experiences,strengthen subsequent evaluations,and foster continuous improvement in students'digital literacy.
