STU406’s Learning Units 1–5 present mobile-first learning as a student-centred, equity-focused approach for UNISA ODeL students, showing how smartphones, low-data and offline-friendly design, and platforms like Microsoft 365 Copilot, OneNote, OneDrive, Google Workspace, and Google Meet support flexible study, collaborative work, and efficient organisation while building core mobile literacy and data-conscious habits; together with guidance on ethical, legally compliant digital citizenship (including POPIA and responsible AI use), these units aim to equip diverse South African students with the practical digital skills, academic resilience, and professional readiness needed to participate confidently in an increasingly digital higher education and workplace environment.
