We present a concept-mapping activity, developed within a youth Participatory Action Research (yPAR) after-school program, to demonstrate how the activity contributed to young people's conceptualization of social structures as interconnected. We analyze fieldnotes from the Change 4 Good yPAR program, which includes primarily Latina/o 4th and 5th grade students attending a California public elementary school. We discuss the concept-mapping activity in terms of its processes and outcomes, and how youth constructed interconnected meanings from thematic community narratives.
