“…Several studies have dealt with the contextual factors (including subject context) in teacher identity and its development (de Freitas, 2008;Drake et al, 2001;Goos & Bennison, 2008;Hobbs, 2012a,b;Hodges & Cady, 2012;Kasten, Austin, & Jackson, 2014;Lutovac & Kaasila, 2014;Owens, 2014;Spillane, 2000;van Zoest & Bohl, 2005).
