“…The results of prior research reviews show that TAs: (a) perform a variety of roles that were generally viewed positively by teachers, TAs, students and parents; (b) often assume primary instructional roles which may hinder the performance of students and should be the responsibility of trained teachers; (c) can foster improved academic, behavioral and social outcomes for students when they are appropriately trained and supervised and; (d) rarely receive adequate training and supervision (Ashbaker & Morgan, 2012;Brock & Carter, 2013;Cajkler & Tennant 2009;Farrell, Alborz, Howes & Pearson, 2010;Giangreco, Suter, & Doyle, 2010;Rispoli, Neely, Lang, & Ganz, 2011;Saddler, 2014;Walker & Smith, 2015). However, the findings of these prior reviews did not include articles published in the last five years (Cajkler, & Tennant, 2009;Farrell et al, 2010;Giangreco, Suter, & Doyle, 2010), did not focus solely on TAs in general education settings (Brock & Carter, 2013;Rispoli et al, 2011;Walker & Smith, 2015), or did not employ a systematic methodology for identifying, selecting, and synthesizing empirical studies (Ashbaker & Morgan, 2012;Giangreco et al, 2010;Saddler, 2014). Furthermore, these reviews were based primarily on research from the United States and the United Kingdom and did not reflect an international perspective.…”
