概要	Design-based pragmatic mixed methods combines the iterative, intervention-focused logic of design-based research (DBR) with the philosophical pragmatism that underpins mixed methods inquiry. Researchers design, test, and refine an educational or organisational intervention across multiple cycles while simultaneously collecting quantitative outcome data and qualitative process data. The pragmatist worldview licenses the integration of both data strands in service of a practical research question: does this design work, for whom, and why?	Action research is a collaborative research methodology in which researchers work with practitioners and community members to investigate a problem, implement change, and evaluate outcomes, cycling through reflection, action, and learning. Developed by Kurt Lewin (1946), action research bridges research and practice, aiming simultaneously to produce knowledge and practical improvement.
