“…Researchers have examined how UDL can be applied to teacher-developed lessons and curricula (Browder, Mims, Spooner, Ahlgrim-Delzell, & Lee, 2008;Dymond et al, 2006;King-Sears et al, 2015). Several studies have examined academic outcomes and engagement with UDL-based digital learning environments (Coyne, Pisha, Dalton, Zeph, & Smith, 2012;Dalton, Proctor, Uccelli, Mo, & Snow, 2011;Hall, Cohen, Vue, & Ganley, 2015;Marino et al, 2014;Rappolt-Schlichtmann et al, 2013). Studies have demonstrated that UDL-based instruction results in positive academic gains and increased engagement for students.…”
