Several studies point out that graduate student teaching assistants have a significant impact on undergraduate learning and student retention ((Bettinger, Long, & Taylor, 2016, Myers, et al. 2012; El-Ghoroury, 2012). Graduate students’ enthusiasm for their discipline affects student learning. One study suggests that Undergraduates who take an introductory course taught by a graduate student are much more likely to major in that subject than those who took the same course from a full-time faculty member (Bettinger, Long, & Taylor).
