“…As shown in Table 2, points were examined in 11 of 19 studies (Barata et al, 2013;Berkling & Thomas, 2013;Charles, Charles, McNeill, Bustard, & Black, 2011;Dominguez et al, 2013;Gåsland, 2011;Li et al, 2013;Mayer & Johnson, 2010;Mekler et al, 2013a;Mekler et al, 2013b;Meyer, 2008;O'Donovan, Gain & Marais, 2013) and are the basis of many gamified elements such as leaderboards and levels (Mekler et al, 2013a). Points can be awarded for a wide variety of tasks such as completing quizzes, attending lectures, taking part in class exercises, solving puzzles, creativity in assignments (Charles et al, 2011;O'Donnell et al, 2013), completing practice questions, or correct answers (Mekler et al, 2013a).…”
