“…The interdisciplinary research on co-teaching has been largely top-down in nature, utilizing self-reporting methods such as surveys or interviews to generate descriptions of effective practices ( Friend et al, 2015 ); however, a small body of work employing methods that fall under the umbrella of discourse analysis uses a more bottom-up approach to understanding teacher collaboration. Whether it be through the lens of positioning theory (see e.g., Martin-Jones & Saxena, 1996 ), systemic functional linguistics (see e.g., Gardner, 2006 ;Luo, 2013 ), critical discourse analysis (see e.g., Ashton, 2010Ashton, , 2014Ashton, , 2016Creese, 2002 ), conversation analysis (CA) (see e.g., Butterfield & Bhatta, 2015 ;King, 2016, King, 2018Lee, 2016 ;Park, 2014 ), or a loosely defined analysis of classroom discourse (see e.g., Roth et al, 2005 ), these studies provide a detailed analysis of co-teaching by using recordings of naturally-occurring data to capture and shed light on the nuances of actual classroom interaction. In addition to inclusion and teacher training settings, these studies often examine English as a Foreign or Second Language (EFL or ESL) classrooms where teachers with different language backgrounds are paired to enhance the linguistic and cultural repertoire in the classroom ( Barratt & Kontra, 20 0 0 ;Carless & Walker, 2006 ).…”
