“…Research has consistently demonstrated that for early elementary students and older struggling readers, explicit instruction of foundational literacy skills provides stu dents from a wide variety of backgrounds with the greatest opportunity to learn to read proficiently (e.g., Blachman, Tangel, Ball, Black, & McGraw, 1999;D'Angiulli, Siegel, & Maggi, 2004;Torgesen et al, 2001). However, teachers, in general, have an insufficient understanding of foundational literacy skills necessary for providing effective reading instruction based on the science of reading (e.g., Brady & Moats, 1997;Moats & Foorman, 2003;Pittman, Zhang, Binks Cantrell, Hudson, & Joshi, 2020;Spear Swerling & Cheesman, 2012;Washburn, Binks Cantrell, Joshi, Martin Chang, & Arrow, 2016). Literacy researchers have pointed to teacher preparation programs as the reason for knowl edge gaps among educators (Binks Cantrell, Washburn, Joshi, & Hougen, 2012;Greenberg, Walsh, & McKee, 2015;ILA, 2020;Joshi et al, 2009;Moats, 2014Moats, , 2020, which has stimulated interest in rais ing teachers' literacy knowledge (ILA, 2018;Inter national Dyslexia Association, 2018).…”
