“…Professional learning is also critical to inclusive reform as both teachers (Scruggs & Mastropieri, 1996) and principals (Billingsley et al, in press) frequently reported that they are not prepared to meet the needs of students with disabilities. Across studies of inclusive reform, leaders worked to ensure that teachers and staff had opportunities to learn about topics such as the effects of inclusion, differentiating instruction, collaboration and co-teaching, methods to teach students with specialised needs, and evidence-based practices, such as positive behavioural interventions and supports (e.g., Burstein et al, 2004; Causton-Theoharis et al, 2011; DeMatthews & Mawhinney, 2014; Mayrowetz & Weinstein, 1999; Pierson & Howell, 2013; Shogren et al, 2015). Principals often participated in these professional learning opportunities, modelling their commitment to inclusion (e.g., DeMatthews & Mawhinney, 2014; Mayrowetz & Weinstein, 1999).…”
