“…Teachers with a variety of expertise and experience have benefitted from collaborating in Lesson Study programs. For example, pre-service (Roberts, Benedict, Kim, & Tandy, 2017;Sims & Walsh, 2009), elementary (Cheung, 2011;Gutierez, 2016), middle (Lieberman, 2009), and high school (Cajkler, et al, 2015) teachers have developed professionally; so too have college instructors (Dotger, 2011). Scholars have used Lesson Study to investigate contexts where teachers have taught students Math (Leavy & Hourigan, 2016), Science (Lewis & Tsuchida, 1997), English (Nami, Marandi, & Sotoudehnama, 2016), Modern Languages (Cajkler & Wood, 2016), and social studies (Halvorsen & Kesler Lund, 2013;Marton & Pang, 2006;Matoba et al, 2007).…”
