“…In recent years, scholars have underscored the potential for collaboration between general education and ESOL teachers (Crandall & Kaufman, 2002;Davison, 2006;Dove & Honigsfeld, 2010;Haynes, 2007;Hoffman & Dahlman, 2007;Rushton, 2008). Our study extends a growing body of research that has examined teacher collaboration in terms of organisational factors, discourse, relationships, perceptions and identity (Arkoudis, 2006;Creese, 2006;Davison, 2006;Gardner, 2006;Naraian, 2010;Pawan & Ortloff, 2011;Sawyer & Rimm-Kaufman, 2007) and instead frames collaborative teaching as a key opportunity for teacher learning (Doppenberg, Bakx, & den Brok, 2012;Hindin, Morocco, Mott, & Aguilar, 2007). In response to previous studies which have highlighted epistemological and pedagogical gaps between ESOL and mainstream teachers (Arkoudis, 2006;Creese, 2002Creese, , 2006Davison, 2006;Gardner, 2006), our study sought to understand what tools teachers may use to bridge those gaps.…”
