สรุป	Visual elicitation single case study is a qualitative design that embeds photo or image elicitation techniques within a bounded, in-depth investigation of a single case — a person, community, program, or event. Photographs, drawings, or participant-produced images are introduced into interviews to prompt richer, more vivid accounts than verbal questioning alone can generate, while the single case study frame provides the disciplined contextual analysis needed to understand the case as a whole.	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.
