“…Finally, students' learning is improved and deepened. Group work was seen to generate a lot of discussion (Greenop, 2007;Li et al, 2010;Ibnian, 2012;Arumugam et al, 2013), lead to the construction of new knowledge (Tuan & Neomy, 2007;Li et al, 2010), help students understand concepts better (Hendry et al, 2005;Greenop, 2007;Al-Sheedi, 2009;Li et al, 2010), learn more (Holloway, 2004;Smialek & Boburka, 2006;Wichadee, 2007) and perform better on final exams (Meteetham, 2001;Smialek & Boburka, 2006). Students in groups support and influence each others' learning (Hendry et al, 2005), clever students help weak students (Smialek & Boburka, 2006;Tuan & Neomy, 2007), weak students start to ask more questions and ask for help when they never do in a lecture (Smialek & Boburka, 2006) and finally students become fully engaged in course content (Yazedjian & Kolkhorst, 2007).…”
