“…and (2) What variables predict teachers' perceived usefulness of AT? Previous research has demonstrated that teacher training on AT is critical for effective implementation (Abu-Alghayth, 2020; de Joode et al ., 2012; Flanagan et al ., 2013; Mundy et al ., 2012), that teacher knowledge of AT is consistently reported as a barrier to effective implementation (Flanagan et al ., 2013; Lee and Vega, 2005), as is access to AT resources (Lee and Vega, 2005) and administrator support for AT implementation (Morrison, 2007; Raskind et al ., 1999; Reed and Bowser, 2012). Teacher knowledge (Lamond and Cunningham, 2020) and teacher attitudes (Chukwuemeka and Samaila, 2020) are related to greater perceived usefulness of AT, but previous research on the impact of training on perceived usefulness of AT has been mixed (Lamond and Cunningham, 2020; Lee and Vega, 2005).…”
