“…The mentioned positive effects of the cooperative organization of the math class are proven right, as much in real settings as in virtual ones, in such a way that a promising new line of research on synchronous and asynchronous learning which relies on Information Technologies as an essential backup for cooperation has appeared (Rubia & Guitert, 2014). In this regard, the interactive video, tablet computers, digital pencils, the interactive board or personal computers have turned out powerful tools for the implementation of cooperative learning approaches (Álvarez, Salavati, Nussbaum, & Milrad, 2013;Jackson, Brummel, Poliet, & Greer, 2013;Tsuei, 2012), giving rise to a new, specific line of work known as CSCL (ComputerSupported Cooperative Learning). However, even though the positive effects of cooperation on academic performance are conclusively proven (Roseth, Johnson, & Johnson, 2008), the effectiveness of any cooperative methodology depends on an optimal harmonization between three structures (task, goal and reward) and two parameters (equality and mutuality).…”
