We sought to better understand the roles and expectations of the peer mentors themselves in a pre-health program for first-generation students, many of whom identify as…

Understanding social interactions among students comprises a rich area of physics education research. Here we focus on the social interactions in introductory physics laboratories (labs). Most existing research in such contexts focuses on within-group social dynamics, however, we argue that interactions between different lab groups are just as…
