Sociocultural Learning Theory

A theory of learning developed by Lev Vygotsky that argues cognitive development and knowledge acquisition are fundamentally social, mediated by language, culture, and interaction with more knowledgeable others. Key concepts include the zone of proximal development (the gap between what a learner can do alone and with guidance) and scaffolding — structured support that is gradually removed as competence grows. In accessibility education, sociocultural theory informs the design of cohort-based training, pair-based code review for accessibility, participatory design sessions with disabled users, and serious games that simulate realistic social contexts where accessibility decisions are negotiated rather than merely memorized.
