概要	Design-based quantitative-priority mixed methods research integrates a design-based research (DBR) framework — which involves iterative cycles of design, implementation, and refinement in naturalistic settings — with a mixed methods approach where quantitative data collection and analysis carry the primary evidentiary weight. Qualitative data are gathered in a supporting role to illuminate, explain, or refine quantitative findings across iterative design cycles.	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.
