RT Journal Article SR Electronic T1 Are Professors Worth It? The Value-added and Costs of Tutorial Instructors JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0417-8752r2 DO 10.3368/jhr.55.3.0417-8752R2 A1 Feld, Jan A1 Salamanca, Nicolás A1 Zölitz, Ulf YR 2018 UL http://jhr.uwpress.org/content/early/2018/12/05/jhr.55.3.0417-8752R2.abstract AB A substantial share of university instruction happens in tutorial sessions— small group instruction given parallel to lectures. In this paper, we study whether instructors with a higher academic rank teach tutorials more effectively in a setting where students are randomly assigned to tutorial groups. We find this to be largely not the case. Academic rank is unrelated to students’ current and future performance and only weakly positively related to students’ course evaluations. Building on these results, we discuss different staffing scenarios that show that universities can substantially reduce costs by increasingly relying on lower-ranked instructors for tutorial teaching.
