“…Preservice teachers who completed coursework related to teaching ELLs expressed favorable attitudes toward heritage language maintenance (Markos, 2012), toward using L1 in instruction (Hutchinson, 2013), toward the inclusion of ELLs in mainstream classrooms (Clark-Goff & Eslami, 2016;Hutchinson, 2013), and toward their ability to teach ELLs (Clark-Goff & Eslami, 2016;Jimenez-Silva & Olson, 2012;Turgut, Adibelli Sahin, & Huerta, 2016). Inservice teachers also expressed more positive attitudes after participating in professional development related to teaching ELLs (Andrei, Ellerbe, & Cherner, 2015;Brooks & Adams, 2015;Hansen-Thomas, Grosso Richins, Kakkar, & Okeyo, 2016;2012;Tran, 2014).…”
