In this paper, we discuss ways collaborative research groups can be used and what students appear to learn about social science reasoning and quantitative literacy from such groups. Data are from field observations, pre- and post-semester surveys in both collaborative and traditional courses, end of the semester student comments, and student work on semester-long group-based projects. The findings illuminate teaching and learning processes, cognitive and personal learning outcomes, and remaining challenges. Students resist having to work in groups, while simultaneously becoming attached to their group and acknowledging its importance. In the end, many students see the importance of both social science reasoning and quantitative skills and demonstrate the ability to articulate key components of both. Challenges that remain include more specific measures of particular skills, potential group conflicts, and active learning within a culture of consumerism and entitlement.
