概要	Participatory Conversation Analysis (PCA) extends classical Conversation Analysis by actively involving the people whose talk is being studied in the analytical process. Rather than treating analysis as the researcher's exclusive domain, PCA invites practitioners, community members, or research participants to co-review recordings or transcripts of their own interaction, contribute insider meanings, and collaboratively refine the interpretation of interactional patterns. The approach is widely used in education, healthcare communication, and professional learning contexts.	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.
