Research has shown that youth and their communities benefit from civics education, with its aim to prepare citizens for democracy. However, civics education for adolescents in the United States is not equitable, and determining how to best measure aspects of civic development in younger adolescents is a challenge. In this qualitative study, we explored how the constructs of action civics and civic purpose might inform teachers, other practitioners, and researchers who are interested in understanding the kinds of educational opportunities that promote civic development in young adolescents. Specifically, we examined how activities characteristic of an action civics approach to civic education in the context of a week-long summer civics camp would influence young adolescents' thinking across the dimensions of civic purpose. We conducted focus groups with 49 young adolescents (entering 5th-9th grades) as they participated in the civics camp, and we analyzed transcripts using qualitative content analysis. Our findings reveal four key considerations for promoting civic purpose development in young adolescents: the importance of adult guides, the significance of developmentally matched activities, opportunities for growth in educating diverse and marginalized youth in the civics camp setting, and action civics as a curricular mechanism for promoting civic purpose.
