“…Despite high levels of funding and publicity for STEM education, systemic reform across the disciplines at the undergraduate level has been slow (Dancy and Henderson, 2008; Fairweather, 2008; Austin, 2011; Marbach-Ad et al ., 2014). Breadth of coverage continues to dominate depth of coverage in many introductory, gateway science courses (Daempfle, 2006; Momsen et al ., 2010; Alberts, 2012; Luckie et al ., 2012), student attrition in STEM fields continues at a high rate (Chen, 2013; King, 2015), and a gap between men and women and between majority and minority students persists in in-class participation, overall course grades, and degree attainment (Madsen et al ., 2013; Eddy et al ., 2014; Gayles and Ampaw, 2014; Brown et al ., 2016), although some conflicting evidence shows that the gender gap is closing (Ceci et al ., 2014; Miller and Wai, 2015). …”
