概要	Embedded transformative mixed methods is a research design that nests one type of data (quantitative or qualitative) inside a dominant dataset of the other type, with both strands guided by an overarching transformative framework — such as feminist, disability rights, or social justice theory. The design serves research questions where statistical breadth and in-depth qualitative insight must both speak directly to equity, empowerment, or systemic change goals.	Critical ethnography is a qualitative research approach that combines sustained fieldwork immersion with explicit critical theory to examine how power, inequality, and ideology shape the lived experiences of marginalised communities. Unlike conventional ethnography, which aims to describe a culture as it is, critical ethnography commits the researcher to questioning what is taken for granted and to producing knowledge that can serve as a resource for social change. Rooted in Frankfurt School critical theory and expanded through feminist, postcolonial, and race-critical traditions, it treats the research process itself as a political act.	Participatory Action Research (PAR) is a qualitative, community-centred methodology in which researchers and community members collaborate as co-investigators to identify a shared problem, take deliberate action, observe outcomes, and reflect critically on results — cycling iteratively until meaningful change is achieved. Unlike conventional research that studies people from the outside, PAR treats participants as active agents who co-own the research process, the knowledge produced, and the practical interventions that follow.
