“…National calls for better graduate training programs have echoed this need (Leshner, 2018;Leshner & Scherer, 2019;Love Stowell et al, 2015;Tanner & Allen, 2006), as well as the inherent benefits of pedagogical training for the research field as well (Feldon et al, 2011). Some of these needs may be met by course-based learning about pedagogy (Baumgartner, 2007;Deshler et al, 2015), while other methods include explicit mentorship (Lockwood et al, 2014), community-based practice (Brower et al, 2007;Price et al, 2021), or apprenticeship in K-12 teaching (Ufnar & Shepherd, 2021). Frequently, these efforts are targeted at the level of the graduate teaching assistant (DeChenne et al, 2015;Deshler et al, 2015;Gilmore et al, 2014;Reeves et al, 2016;Rivera, 2018;Schussler et al, 2015;Wan et al, 2020), which is an environment that is well suited for improving TA-led classroom effectiveness and introducing graduate trainees to pedagogical development.…”
