Course-based undergraduate research experiences (CUREs) have emerged as a viable platform to engage large numbers of students in real-world scientific practices. Historically, CUREs have been offered throughout science, technology, engineering, and mathematics curricula at both the introductory and advanced levels and have been facilitated by a variety of individuals, including faculty members, postdoctoral fellows, and graduate teaching assistants (GTAs). This latter population, in particular, has increasingly been tasked with facilitating CUREs, yet they often receive little meaningful professional development to improve pedagogical skills vital to this type of instruction. To address this disparity, we designed and evaluated a semester-long intervention to support GTAs (N = 7) responsible for leading CUREs at our institution during the Fall 2020 semester. Intervention activities included synchronous interactive discussions, reflective journaling, and asynchronous practical exercises. Analysis of retrospective postintervention survey responses and focus group interview data revealed that participants exhibited gains in their understanding of the dimensions of CUREs, strategies for mentoring undergraduates, and use of various pedagogical techniques as well as confidence in addressing and adopting those dimensions and strategies in their courses. Furthermore, participants reported finding value in the sense of community created through the intervention, which served as a means to share ideas and struggles throughout the term.
