Semiotics of the Digital Shift: Multimodal ODL Resources and Philosophical Discourse Articulation at National Open University of Nigeria

Abstract

This qualitative inquiry examines the semiotic transformation initiated by the 
transition from linear print to multimodal Open Distance Learning (ODL) resources at 
the National Open University of Nigeria (NOUN). The purpose of this study is to 
explore how multimedia ensembles including lecture videos, podcasts, and 
interactive diagrams reshape the rhetorical texture of student articulation regarding 
complex philosophical concepts, moving beyond traditional focus on comprehension 
scores. The research employed a qualitative approach, utilising semi-structured focus 
group discussions with 30 students to identify how multimodality provides new 
semiotic affordances for fluid expression in academic English. The findings reveal a 
significant shift in conceptual depth for 80% of participants, with student engagement 
rising by 36% compared to traditional text-only approaches. These results indicate 
that the multimodal medium alters the nature of the philosophical message itself, 
effectively aligning with African sociocultural modes of knowledge transmission. 
Consequently, the study concludes that multimodal resources are essential 
instruments for epistemic justice. It recommends institutionalising multimodality as 
a core pedagogical component, investing in high-fidelity digital infrastructure, and 
providing specialised faculty training in social semiotics. By advocating for a digital 
humanities approach within the NOUN curriculum, the study highlights the 
significance of multimodal resources in fostering contemporary African critical 
discourse and bridging the gap between theoretical knowledge and lived experience. 
This research offers substantial value by providing context-sensitive evidence of how 
digital shifts can enhance student success and belonging in large-scale ODL 
environments.
