As physics laboratory courses (labs) transition from traditional, model-verifying activities to discovery-based investigations, it becomes crucial to understand the role of the instructor in the implementation of various lab types. Prior work has started to address this need by examining either coarse-grained frequencies or fine-grained content of…

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…

While the autonomous nature of free-choice learning can have numerous positive effects on student learning in science fields, there is a lack of research on how college-age adults learn in informal settings. The purpose of this study was to quantitatively describe college-age adults' experiences at informal learning settings by administering the…
