“…When playing games that included challenges, students were more curious about the content area and developed an understanding of the topic (Tan et al, 2013); it seems that, in the presence of challenges, the students felt that although the game was difficult, it was still fun. As a result, the students were engaged (Ke, 2008a;Simkins, Egert, & Decker, 2012). When facing challenges, the students explored the environment and were less frustrated by difficult tasks (Sadler et al, 2013); their knowledge of the subject and their identification of appropriate strategies to solve specific issues also seemed to improve as a result of challenges (Rubin-Vaughan, Pepler, Brown, & Craig, 2011).…”
