“…Likewise, the rise of cooperative learning to this discipline has brought about not only the implementation of general methods of cooperative learning in this area of knowledge, such as Jigsaw (Naomi & Githua, 2013;Novianti, 2013a;Zakaria, Solfitri, Daud, & Abidin, 2013), STAD (Novianti, 2013b;Zakaria, Chin, & Daud, 2010), or TGT (Ismail, 2000;Ke & Grabowski, 2007), but also the appearance of specific methodologies for this scope, like "Small Group Learning and Teaching in Mathematics" by Davidson (1990b) ), "Team Assisted Individualization" by Slavin (Slavin, Leavey, & Madden, 1984, 1986, "Learning Together" by Johnson and Johnson (Johnson & Johnson, 1991;Özsoy & Yildiz, 2004) or "Cooperative-Individualized Learning Approach in Mathematics" by Serrano . This has triggered a line of research organized around the comparison of the effectiveness of different cooperative learning methods on specific intra-subject variability and, especially, on students' performance on mathematics (Awofala, Fatade, & Ola-Oluwa, 2012;Parchment, 2009;Syahrir, 2011).…”
