概要	Design-based concurrent embedded mixed methods design merges the iterative intervention logic of Design-Based Research (DBR) with the concurrent embedded mixed methods structure, in which one data type (typically qualitative) is nested within a dominant dataset (typically quantitative) and both are collected simultaneously within each design cycle. This approach is especially suited to educational intervention and applied research contexts where a product, curriculum, or tool is being developed, tested, and refined through repeated cycles of implementation and analysis.	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.
