“…Since the 1990s, the number of graduate students teaching at larger universities in the United States, Canada, and elsewhere has increased substantially-so much so that the majority of first-year courses in these universities are often taught by graduate students (Austin, 2002;Marbach-Ad, Schaefer, Kumi, Friedman, Thompson, & Doyle, 2012;Wise, 2011). At the same time, the training of graduate teaching assistants (TAs) has received increased attention (e.g., Blouin & Moss, 2015;Boman, 2013;Hoessler & Godden, 2015;Kenny, Watson, & Watton, 2014). The Council of Graduate Schools and the Association of American Colleges and Universities (AAC&U) developed the Preparing Future Faculty (PFF) program, which charged graduate schools with preparing aspiring academics for a career in higher education (DeNeef, 2002;Kniola, Chang, & Olsen, 2012;Wurgler, VanHeuvelen, Rohrman, Loehr, & Grace, 2013).…”
