The different forms of MR refer to whose cognitive process is regulated and how the group is involved in the MR process (see De Backer, Van Keer, & Valcke, 2015;Iiskala, Vauras, & Lehtinen, 2004;Malmberg, Järvelä, & Järvenoja, 2017;Ucan, 2017;Whitebread et al, 2009;Volet et al, 2017), while the different foci refer to the level of cognitive activity (high, low) being regulated (cf., Grau & Whitebread, 2012;Iiskala et al, 2011;Khosa & Volet, 2014). To date however, research on the relationship of forms and foci of MR to the quality of the group's learning outcome has not been comprehensively examined.…”
