Design-based Explanatory Sequential Mixed Methods Design

This design embeds an explanatory sequential mixed methods structure — quantitative data collection followed by qualitative follow-up — within iterative design-based research (DBR) cycles. The quantitative phase establishes what is happening with a designed intervention or learning environment; the qualitative follow-up explains why. Results then feed directly back into redesign, making the method especially powerful in educational and instructional technology research where both statistical patterns and contextual understanding are needed to refine innovations.
