“…Levitt, 2002), middle (e.g., Hofer & Swan, 2008;Martin et al, 2001), and secondary (e.g., Alazzi, 2008;Chiodo & Tsai, 1997;Vetter, 2010) teachers. Among these studies, multiple content areas were investigated, including ELA (e.g., Camburn & Barnes, 2004;Flynn & Schachter, 2017;Hamel, 2003;Maloch, 2002;Worthy et al, 2015), science (e.g., Diezmann & Watters, 2015;Levitt, 2002;Savasci & Berlin, 2012), and social studies (e.g., Alazzi, 2008;Hofer & Swan, 2008), with researchers examining a variety of practices such as grouping students (e.g., Maloch et al, 2013), using technology in the classroom (e.g., Hughes & Ooms, 2004;Swan & Hofer, 2011), and working with dual language learners (DLL; e.g., Gersten, 1999;Musanti, 2017;Musanti et al, 2009;Palmer et al, 2014). In terms of topical focus, we noted three broad groups of research questions that guided the studies: questions focused on classroom practices (n = 33), particular groups of teachers (e.g., novice, Latinx; n = 16), or the implementation or uptake professional development (n = 10).…”
