摘　　要：随着混合学习的推进,富媒体技术环境带来的学生认知负荷增加问题引发人们关注。为探究混合学习情境下认知负荷对学习投入的影响,本研究基于某中学293位学生的问卷调查结果及其在线学习行为投入数据,利用结构方程模型,探究在线学习行为在心理投入对学习满意度影响中的中介作用,并采用多群组分析法检验认知负荷在其中的调节作用。研究发现,混合学习情境下学生的实质性在线学习投入有限;心理投入与在线学习行为投入对学习满意度有显著正向影响,且在线学习行为投入在心理投入对学习满意度影响中起中介作用;认知负荷通过调节在线学习行为投入对心理投入的表征,改变学习投入对学习满意度的影响机制。本文建议加强教学存在,提升在线学习投入的质量;通过满足学生三种基本心理需求,激发学生内在学习动机,提升心理投入;优化在线学习任务与资源设计,基于动态学情提供及时的学习支持,确保学生的认知负荷处于适当水平,从而保障实质性在线学习,真正发挥混合学习的价值。As blended learning has become an important component of the digital learning in the digital transformation of education in China,the increased cognitive load on students brought about by the rich media technology environment with blended learning has once again raised concerns.To explore the mechanisms of students'cognitive load on learning engagement in a blended learning context,this study used a survey instrument and collected 293 sets of data from students in a middle school.The study first used structural equation modeling to explore the mediating role played by the online learning behavior in psychological engagement affecting learning satisfaction.Then,it used multi-cluster analysis to examine the moderating role played by cognitive load.The findings reveal that online learning engagement is limited in blended learning contexts,and psychological engagement and online behavioral engagement have a significant positive effect on learning satisfaction.In addition,online behavioral engagement mediates the effect of psychological engagement on learning satisfaction and cognitive load moderates the mechanism of the effect of learning engagement on learning satisfaction by influencing the representation effect of online behavioral engagement on psychological engagement.For blended learning,this paper suggests strengthening the teaching presence to enhance the quality of online learning engagement,stimulating students'intrinsic learning motivation to promote psychological engagement through a needs-supportive teaching approach that meets students'three basic psychological needs,optimizing the design of online learning tasks and resources,and providing timely support based on dynamic learning tracking to ensure that students'cognitive load is maintained at an appropriate level to facilitate online learning,which can truly bring in the value of blended learning for education.
