The authors surveyed faculty (n = 239) at three diverse institutions to probe perceived motivations for and barriers to involvement in undergraduate research, scholarship, and creative activity (URSCA) across scholarly disciplines. URSCA mentors were significantly more likely than nonparticipants to express proficiency in involving students in their research/creative activities, to acknowledge student contributions to their scholarly work, and to state that URSCA mentoring should be considered in personnel decisions. More than half perceived that their institutions did not place sufficient value on mentoring URSCA. Results suggested that institutional URSCA cultures could be enhanced by building mentoring into faculty workload, tenure materials, and promotion documents; using early, course-based research to improve student readiness; providing faculty development on research mentoring aimed at underrepresented disciplines; and seeking novel funding sources targeted at faculty-mentored URSCA.
