“…Griffith (2010) studied students who were in their first year of college in 1999 and found only 37% of women versus 43% of men persist to graduate with a STEM major. Several studies (e.g., Riegle-Crumb et al, 2012; Xie and Shauman, 2003; Seymour and Hewitt, 1997) have examined the underlying reasons for the differentials in STEM persistence, by examining persistence after controlling for (latent) variables, such as academic achievement (e.g., Maltese and Tai, 2011), math and science identity (Chang, et al, 2011), interest (Sullins, Hernandez and Fuller, 1995), future time perspective (Husman, et al, 2007), sense of community (Espinosa, 2011), goals (Leslie, McClure and Oaxaca, 1998) or personality traits (Korpershoek, Kuyper and van der Werf, 2012). …”
