“…During this period, studies tended to locate differences in STEM declaration and persistence within an individual's characteristics, such as their interest or ability (e.g., Goldrick-Rab, 2006;Faulkner, 2009;Cech et al, 2011). In addition, many of these studies used the pipeline model, which focused on how individuals and groups moved through education into careers (Metcalf, 2010). More recently, scholars have found that individual variables, such as aptitude and interest, do not alone account for STEM declaration and persistence (Acker and Feuerverger, 1996;Seymour, 1999;Margolis, et al, 2000;Summers and Hrabowski, 2006;Sax, 2008;Hill, et al, 2010;Shapiro and Sax, 2011).…”
