概要	The design-based mixed methods matrix is a systematic framework for selecting and structuring mixed methods research designs. It organises key design decisions — purpose, timing of data strands, point of integration, and weighting of quantitative versus qualitative components — into a coherent matrix that guides researchers toward a defensible, transparent design. The framework draws on the typology traditions of Creswell and Plano Clark and Greene's purposes-based approach.	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.
