“…Because we were most interested in relatively objective outcomes related to student performance, and due to the limits of the primary studies in this area, we did not consider attitudinal outcomes such as science motivation, science interest, and bridge program satisfaction. Rather, we focused on outcomes such as STEM major retention (e.g., Smith, 2017), STEM graduation rates (e.g., Kopec and Blair, 2014), math assessment scores (e.g., Ami, 2001), and class-specific GPAs (e.g., chemistry; Graham et al, 2016). Other outcomes considered in STEM bridge program research are general (non-STEM specific) academic outcomes, including time to graduate (e.g., Whalin et al, 2017), overall GPA (e.g., Graham et al, 2013), and university retention (e.g., Wischusen et al, 2011).…”
