概要	Sequential transformative mixed methods design combines the temporal structure of sequential mixed methods — collecting qualitative and quantitative data in two distinct, ordered phases — with a transformative theoretical framework that centres social justice, equity, and the perspectives of marginalized communities. Either the qualitative or the quantitative phase may come first; the sequence is determined by what the transformative research question demands. The design is guided by the work of Donna Mertens and is systematized in the Creswell and Plano Clark mixed methods typology.	Concurrent transformative mixed methods design collects quantitative and qualitative data simultaneously, guided by a transformative theoretical lens — such as feminist, critical race, disability, or indigenous frameworks — that foregrounds equity, power, and social change. The design gives either strand equal or unequal priority, but both strands are explicitly shaped by the transformative worldview. Findings are merged or compared to generate actionable insights that advocate for marginalized communities.
