Benefits and Challenges of Instructing Introductory Biology Course-Based Undergraduate Research Experiences (CUREs) as Perceived by Graduate Teaching Assistants

摘要

Graduate teaching assistants (GTAs) are often the primary instructors for undergraduate biology laboratories and serve as research mentors in course-based undergraduate research experiences (CUREs). While several studies have explored undergraduate perceptions of CUREs, no previous study has qualitatively described GTAs’ perceptions about teaching CUREs, despite the essential instructional role GTAs play. The purpose of this phenomenological study was to describe and ascribe meaning to the perceptions that GTAs have regarding benefits and challenges with instructional experiences in introductory biology CUREs. We conducted semistructured interviews with 11 GTAs instructing an introductory biology CURE at a 4-year public university. We found that, while GTAs perceived professional benefits such as experience in research mentoring and postsecondary teaching, they also described challenges, including the time required to instruct a CURE, motivating students to take ownership, and a lack of expertise in mentoring undergraduates about a copepod-based CURE. Feelings of inadequacy in serving as a research mentor and high levels of critical thinking were also cited as perceived issues. We recommend that the greater responsibility and increased time commitment perceived by GTAs in the current study warrants reconsideration by lab coordinators and administrators as to what content and practices should be included in pedagogical training specifically designed for CURE GTAs and how departmental and institutional policies may need to be adapted to better implement CUREs.
