“…When investigating the effect of story structure in games, in particular, strong explicit story structures in educational games were found to have a positive effect on declarative knowledge acquisition (Gustafsson, Katzeff, & Bang, 2010;Smith & Baker, 2011), performance (Kelleher, Pausch, Pausch, & Kiesler, 2007) and particularly a positive effect on procedural knowledge or skill acquisition (Serrano & Anderson, 2004). Research also found a positive effect on learning, (programming) skills and engagement (Dickey, 2006;Dickey, 2011;Jemmali, Bunian, Mambretti, & El-Nasr, 2018;McQuiggan, Rowe, Lee, & Lester, 2008;Rowe, Shores, Mott, & Lester, 2011). Moreover, in their recent quantitative meta-review, Wouters and van Oostendorp (2017) report a positive effect of narrative elements in games, especially on motivation.…”
