“…The traditional theoretical model of developing supportive teacher beliefs, or buy‐in, regarding PBM is that increasing teacher knowledge and use of PBM will result in improved student behavior, which will then foster teacher supportive beliefs and sustained implementation (Guskey, 2002; Mitchell, Hirn, & Lewis, 2017). However, research has shown that this model often does not hold (e.g., Johnson et al, 2014; Simonsen et al, 2017), potentially due to a variety of faulty assumptions about teacher implementation, including that teachers can readily detect changes in student behavior and that implementation will require little adjustment to other aspects of teacher practice (Gersten, Vaughn, Deshler, & Schiller, 1997). On the contrary, in some contexts, changes in teacher beliefs may be necessary to enact sustained changes in practice (Brownell & Leko, 2018).…”
