  The objective of this exploratory study was to examine the interpersonal
dynamics of an afterschool math club for middle schoolers. Using social network
analysis, two networks were identified and analyzed: (a) a network of
friendship relationships and (b) a network of working relationships. The
interconnections and correlations between friendship relationships, working
relationships, and a student opinion survey were studied. We identified a core
working group of students from within the network of working relations. This
group acted as a central go-between for other members in the club. This core
working group also expanded into the largest friendship group in the friendship
network. A second group was formed from popular but aloof students who reported
less impact from the club. Although there were working isolates, they were not
found to be socially isolated. Students who were less popular tended to report
a greater favorable impact from club participation than those who were more
popular.
