THE EFFECTIVENESS OF MULTIMODAL TEACHING TECHNOLOGIES IN DEVELOPING STUDENTS' SENSORY-PERCEPTUAL COMPETENCIES

This conceptual review examines the effectiveness of multimodal teaching technologies in fostering the sensory-perceptual competencies of university students. Drawing on established theoretical frameworks — the Cognitive Theory of Multimedia Learning, Dual Coding Theory, Cognitive Load Theory, the multimodality tradition in social semiotics, and sociocultural perspectives on mediated learning — the paper synthesises decades of conceptual and empirical work to clarify how multimodal instruction interacts with the perceptual systems through which higher-education learners receive, integrate, and interpret information. A structured narrative-review procedure was applied to seminal monographs and peer-reviewed articles published between 1966 and 2014. The synthesis indicates that well-designed multimodal environments support sensory-perceptual development by (i) distributing processing load across visual and auditory channels, (ii) enabling referential connections between verbal and non-verbal representations, (iii) cultivating perceptual differentiation through guided attention, and (iv) embedding perception in semiotically rich, socially mediated activity. The discussion outlines design implications and identifies boundary conditions — notably the redundancy, split-attention, and modality effects — that constrain when multimodality is beneficial. The paper concludes that multimodal technologies are most effective when their design is principled rather than additive: multiplying channels does not, by itself, multiply learning.
