“…In the field of education, performance feedback is defined as the process of providing “verbal, written, or graphical feedback about [teachers’] implementation of an intervention during an observation in an effort to improve their implementation during subsequent interventions” (Casey & McWilliam, 2011, p. 1). The field has identified performance feedback as a means for providing ongoing support following training to promote the implementation of evidence-based classroom practices such as positive verbal behaviors such as expansions (Barton & Wolery, 2007) and descriptive praise (Hemmeter et al, 2011), instructional strategies (Boat et al, 2009), incidental teaching (Casey & McWilliam, 2008), and family-centered practices (Brown & Woods, 2011), as well as early intervention home visiting practices (Marturana & Woods, 2012).…”
