This study contributes to sustainable EdTech research by developing a Dual-Sided Equity Model that explains how digital learning platforms can simultaneously expand educational opportunities and reproduce structural inequalities. It introduces the concept of Conditional Educational Equity, arguing that digital access alone does not ensure equitable outcomes; learners must also have the capability to participate meaningfully and benefit from digital learning. By integrating platform affordances, structural digital divides, and PESTEL conditions, the study provides a context-sensitive framework for evaluating the sustainability and human impact of EdTech in Bangladesh and similar developing contexts.
