“…There is a multitude of evidence confirming that the STAD model of cooperative learning is not only ideal for improving students' conceptual understanding and achievement in mathematics (Ardiyani et al, 2018;Kramarski & Mevarech, 2003;Mukuka, Balimuttajjo, et al, 2020a) but also for improving students' social interactions, motivation, self-confidence and attitude towards mathematics (Hossain & Ahmad, 2013;Slavin, 1987;2015).
