“…The second largest set of studies used mostly single-subject, experimental and quasi-experimental methodologies to demonstrate the efficacy of multicomponent approaches for increasing teachers’ knowledge, instructional skills, and/or student outcomes in a variety of areas (e.g., functional behavioral assessment, vocabulary instruction, and elementary reading, writing, and mathematics instruction) using mostly single-subject and quasi-experimental designs (see Online Appendix A). Multicomponent innovations incorporated some combination of initial training in strategies (and sometimes content knowledge underlying those strategies) with at least two or more of the following active learning opportunities: modeling, practice in structured settings, action research projects, professional learning community, and/or feedback (e.g., Browder et al, 2012; Cavazos, Linan-Thompson, & Ortiz, 2018; Hoover & Soltero-González, 2018; Horrocks & Morgan, 2011; Kennedy et al, 2018; Lembke et al, 2018). Findings from 10 studies showed that multicomponent interventions were able to change teachers’ use of discrete instructional behaviors (e.g., Horrocks & Morgan, 2011) and more complex instructional routines (e.g., Kennedy et al, 2018; Lembke et al, 2018).…”
