“…Research such as the study carried out by (Mugla & Seedhouse, 2005), teachers use CS as an interactional resource and as an effective pedagogical tool to achieve their desired objectives (Turnbull & Arnet, 2002). Other scholars (Ariffin & Hussin, 2011;Becker, 2001;Chimbganda & Mokgwathi, 2012;Moghadam, Samad, & Shahraki, 2012;Hisham Ahmad & Jusoff, 2009;Lee, 2001;Mugla & Seedhouse, 2005;Qing, 2010;and Yao, 2011), favor CS as a pedagogical instrument since its usefulness is demonstrated in each study This study acknowledges that CS can be used by monolinguals when changing styles, (Martin, 1999a;Auer, 1998) but the scope is narrowed down to the alternation between two languages, specifically Spanish and English in Mexico. The alternation of L1 and L2 in the classroom is generally known as code-switching (Martin, 1999b;Milroy and Muysken, 1995;Auer, 1998).…”
