概要	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.	The exploratory sequential mixed methods design is a two-phase research framework in which a qualitative phase is conducted first to explore a poorly understood phenomenon, and the findings then inform a subsequent quantitative phase — typically to develop and test a survey instrument, measure a theory, or generalize qualitative insights to a larger population. The qualitative strand guides what is measured; the quantitative strand tests or extends those findings at scale.
