This thesis is about an investigation of how children with philosophical experience use philosophical discussion as a way of doing research. A Lawrence Stenhouse description of 'research' as "systematic and sustained enquiry made public" served as my starting point for what to count as 'research'. As an interpretive case story of children participating in research as co-researchers, this research is about how I engaged in an after-school Discussion Research Group co-research project with seventeen volunteer students from my Philosophy for Children (...) classes. Our co-research was a methodological experiment in merging genres of research in which we adapted and combined Philosophy for Children and qualitative research techniques in a philosophical exploration of philosophical discussion. Bringing together the children's philosophical expertise and my interest in the use of qualitative research methodologies, I explored how and whether 'to do philosophy' is 'to do research'. (shrink)
