Abstract:
As Nigerian universities navigate a rapid digital transition, the integration of Information and Communication Technology (ICT) and multimedia tools has become essential for pedagogical resilience. This study explores the application of Cognitive Load Theory (CLT) and Mayer's Cognitive Theory of Multimedia Learning (CTML) to optimise instructional design within the unique Nigerian socio-technical context. Despite the transformative potential of tools such as Augmented Reality (AR) and virtual labs, their efficacy is often hindered by significant challenges, including unreliable power supply, high internet costs, varying digital literacy, and the cognitive demands placed on second-language English learners. Employing a qualitative secondary research design and thematic analysis of peer-reviewed literature and National Universities Commission (NUC) publications, the study evaluates how evidence-based design principles such as segmenting and coherence can mitigate extraneous cognitive load. Findings indicate that while multimedia tools enhance student engagement and achievement across diverse disciplines, successful implementation is frequently stymied by a gap between technology procurement and pedagogical expertise. The paper concludes that CLT serves as a vital bridge between technological adoption and effective learning, transforming complex information into manageable knowledge. To ensure sustainable digital transformation, the study recommends that the NUC mandate CLT-based pedagogical training for academic staff, establish a national framework for indigenous multimedia content, and prioritise resilient infrastructure. By aligning instructional design with human cognitive architecture and local realities, Nigerian higher education can foster deeper cognitive engagement and better prepare graduates for 21st-century professional demands.
