“…Much work has been done to understand how different factors influence the effectiveness of collaborative learning. These factors include students’ participation and social behavior when they learn together (e.g., Abdu et al, 2019 ; Barron, 2003 ; Dillenbourg, 1999 ; Kontorovich et al, 2012 ; Webb et al, 2014 ), effects of teacher support (Dekker & Elshout-Mohr, 2004 ; van Leeuwen & Janssen, 2019 ; Webb, 2009 ), and, specifically for the current article, the effects of different group formations on the effectiveness of learning (e.g., Lou et al, 1996 ; Pearlstein, 2021 ). Educators can use learning analytics systems to support collaborative learning (Wise & Schwarz, 2017 ): For example, by presenting data about the indicators of collaborative learning situations (D’Angelo et al, 2015 ; Schwarz et al, 2018 ; Wise & Schwarz, 2017 ), supporting teachers’ decision-making in regard to collaborative learning (Martinez-Maldonado, 2019 ; van Leeuwen, 2015 ), supporting co-reflection on the collaborative learning process (Schwarz et al, 2015 ) and, specifically to this current article, group formation (see Borges et al, 2018 ; Maqtary et al, 2019 ).…”
