Self-Efficacy and Performance of Research Skills among First-Semester Bioscience Doctoral Students

Research skills, especially in experimental design, are essential for success in bioscience doctoral training. While there is a growing body of literature on the development of research skills among science, technology, engineering, and mathematics doctoral students, very little is specific to biosciences. We seek to address this gap by characterizing aptitude and self-perceived facility with research skills among incoming bioscience doctoral students, as well as how and why they change over the first semester of doctoral training. Our results reveal variability in research skills self-efficacy and a wide range in aptitude and self-perceived facility with experimental design at the beginning of the semester, both of which are uncorrelated with the duration of predoctoral research experience. We found that students significantly improved in both experimental design performance and research skills self-efficacy over their first semester; students attributed their experience and comfort with experimental design to a variety of factors, including laboratory research, course work, mentoring, and interaction with colleagues. Notably, we found that the largest research skills self-efficacy gains were aligned with material that was covered in students’ first-year course work about experimental design. Together, these results demonstrate the importance of explicit training in experimental design and other research skills early in bioscience doctoral training.
