“…However, questions about implementation and scaling-up of the SDLMI remain, particularly in terms of supports needed by teachers to sustain the SDLMI as a part of ongoing instruction over time and as other interventions are introduced. Researchers have begun to define and examine the impact of an SDLMI coaching model (Hagiwara, Shogren, Lane, Raley, & Smith, in press; Shogren et al, 2019) as well as online supports or online plus coaching supports for implementation of the SDLMI (Shogren, Wehmeyer, Lane, & Quirk, 2017) to explore the impact of these factors on adoption. Although research has generally suggested adequate fidelity of implementation in large-scale studies (Burke, Shogren, Antosh, LaPlante, & Masterson, 2019; Shogren, Raley, et al, 2018), less is known about how teachers perceive their ability to implement the SDLMI with fidelity, and the degree to which these perceptions are stable over time and/or shaped by the introduction of other intervention and instructional demands.…”
