      abstract = {Digital learning initiatives in the Global South are frequently designed on the tacit assumption of continuous, affordable, and high-bandwidth connectivity, an assumption that does not hold for the learners such initiatives most aspire to reach. When connectivity is intermittent, metered, and expensive, “connected-by-default” designs degrade into unusable ones, widening rather than narrowing educational inequality. This paper argues that offline operation should be treated not as a degraded fallback but as the primary, first-class design condition for learning technology in low-connectivity environments. Grounded in the literatures of information and communication technologies for development (ICT4D), human–computer interaction for development (HCI4D), mobile learning, and delay-tolerant networking, we propose TIDAL, a Tolerant, Inclusive, Device-first, Adaptive Learning framework. TIDAL couples five design tenets with a four-layer reference architecture (a local-first content and data layer, an opportunistic synchronization layer, an adaptive experience layer, and a pedagogical continuity layer), bound together by a cross-cutting concern for data integrity, security, and sustainability. The framework reframes connectivity as an intermittent resource to be exploited opportunistically rather than a precondition to be assumed. We illustrate TIDAL through a worked scenario of teacher-mediated secondary-school delivery in a rural setting and discuss the framework’s strengths, limitations, and boundary conditions. TIDAL is offered as a conceptual scaffold for designers, implementers, and evaluators, and as a research agenda for empirically validating offline-first learning design.},
