Educational Technology and AI: Bridging Cognitive Load and Learner Engagement for Effective Learning

Artificial Intelligence (AI) has rapidly permeated online learning environments, promising enhanced personalization, automation, and engagement. However, empirical evidence remains fragmented on how AI-driven systems influence effective learning—defined here as the integration of knowledge acquisition, retention, and application. Existing research often isolates key elements such as design quality, learner attributes, and instructional support, while the role of learner engagement has received comparatively less attention. Addressing this gap, this study examines how design principles, technology proficiency, adaptive learning pathways, self-efficacy, and learner engagement interact to shape educational outcomes in AI-mediated environments. Drawing on Cognitive Load Theory (CLT), Social Cognitive Theory (SCT), and Vygotsky’s Sociocultural Theory, the analysis of 372 university students reveals that adaptive learning pathways and technological proficiency play pivotal roles in optimizing cognitive load. Self-efficacy functions as a key mediator, while instructor involvement moderates the effectiveness of AI design and personalization. These findings highlight the importance of aligning AI technologies with both pedagogical design and learner psychology to foster sustainable, equitable, and effective online education.
