خلاصه	Design-Based Transformative Mixed Methods Design integrates Donna Mertens' transformative paradigm — which foregrounds social justice, equity, and the perspectives of marginalized groups — with the iterative intervention cycles of design-based research. It systematically combines quantitative and qualitative data across successive design-test-refine cycles to both understand and actively improve conditions for underrepresented communities. The approach is prominent in education, public health, and community-engaged research where changing unjust structures is an explicit goal alongside knowledge generation.	Design-based research (DBR) is an iterative, interventionist methodology that simultaneously designs educational interventions and builds theory about how and why those interventions work in authentic, complex settings. Originating in Ann Brown's 1992 classroom experiments and Allan Collins's parallel work, DBR treats the learning environment as both the object of study and the site of theory generation, cycling through design, enactment, analysis, and redesign until both practical improvement and theoretical insight are achieved.
