“…Most previous studies used videos roughly 2 minutes long and had anywhere from 6 to 16 segments (Khacharem et al ., 2013; Mayer & Chandler, 2001; Spanjers et al ., 2012; Spanjers, Wouters, Van Gog, & Van Merriënboer, 2011). A few studies have gone beyond 2 minutes in length, but still generally are 9 minutes or less (Biard, Cojean, & Jamet, 2018; Doolittle, Bryant, & Chittum, 2015; Hasler et al ., 2007). Only two longer studies were found, including one that was 15 minutes (Moreno, 2007) and another that was an hour long (Fong et al ., 2012).…”
