“…This research used social network analysis (SNA) and quantitative content analysis (QCA) to analyze those two dimensions. On the social interaction dimension (see Table 2 ), this research used the group-level SNA metrics to uncover groups’ social attributes, including average path length (APL) , density , average degree , average closeness , average betweenness , reciprocity , global clustering coefficients ( GCC) , the inverse coefficient of variation (ICV) of student interaction, and centralization (see Ouyang, Chen, et al, 2021 ; Ouyang, Ling, et al, 2021 ; Ouyang & Scharber, 2017 ). Since students sometimes did not refer to a specific peer during the online discussions, it was difficult to identify the receiver; in this situation, the receiver was denoted as “all” when the network data was processed.…”
