요약	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.	The sequential exploratory mixed methods design begins with a qualitative phase to explore a poorly understood phenomenon, then builds on those findings in a second quantitative phase — most commonly to develop and test a measurement instrument, or to test whether themes identified qualitatively generalise across a broader population. The two phases are conducted in sequence, with qualitative results explicitly informing the design and content of the quantitative strand.
