“…The positive effects on user motivation of entertaining and interactive environments which feature eye-catching objects has been amply demonstrated (Allison, Miller, Sturgeon, Nicoll, & Perera, 2010;Horton, 2000;Sancho, Torrente, & Fernández-Manjón, 2009). Because 3-D virtual worlds possess such objects, those environments are thought to stimulate motivation levels (Falloon, 2010;Iqbal, Kankaanranta, & Neittaanmaki, 2010;Sierra, Gutiérrez, Garzón-Castro, 2012;Zhou, Jin, Vogel, Fang, & Chen, 2011). In the literature, it has also been demonstrated that other features of 3-D environments, such as interactions between users and between individual users and the environment, participation in the provided activities, and the feeling of being truly in the environment (Kapp & Driscoll, 2010) all increase the users' learning capacities (Mishra, 2009).…”
