“…The results show the more facilitative potential of the co-operative learning strategy in promoting achievement in mathematics over the conventional teaching method, thereby supporting the advocates of the former (Awofala, Fatade, & Olaoluwa, 2012;Awofala, Arigbabu & Awofala, 2013). The significant effect of the treatment is consistent with the findings of several studies on student-centred strategies, with co-operative learning being one of these (Lawal & Awofala, 2019;Awofala, 2017a;Awofala, 2014;Awofala, 2011a;Awofala, 2011b;Awofala, Balogun & Olagunju, 2011;Akinsola & Awofala, 2008;Awofala, Fatade & Ola-Oluwa, 2013;Awofala & Nneji, 2011;Ojaleye & Awofala, 2018). However, the significant evidence in favour of co-operative learning strategy is also inconsistent with some findings (e.g., Tracey, Madden, & Slavin, 2010).…”
