“…In the studies reviewed by Dubetz and de Jong (2011), a number of teacher advocates reported that personal and/or professional experiences shaped the curricular and linguistic choices they made. Personal experiences that inform teachers' advocacy efforts include previous K-12 educational experience, experiences they have had as members of immigrant families and as minorities, and their previous experiences as activists (Bos & Reyes, 1996;Flores, 2001;Galindo, Aragon, and Underhill, 1996;Lemberger, 1997;Lenski, 2006;Petrón, 2006;Rodriguez, 2011;Varghase & Stritikus, 2005). Additionally, a number of studies have suggested that formal education, i.e., teacher preparation and professional development, support teachers' ability to challenge subtractive views of bilingualism (Arce, 2004;Flores, 2001;Gersten & Rivera, 1996;Montero-Sieburth & Perez, 1987;Lemberger, 1997;Leone, 1995;Ramos 2005).…”
