15. The entire eTwinning “network”

16. Example SNA How dependent is the eTwinning social network structure on a small core group of eTwinners?

17. Example SNA How dependent is the eTwinning social network structure on a small core group of eTwinners? “ ... no super-hubs who exclusively connect the clusters. Clusters are typically connected via several hubs. In conclusion, although eTwinning is dependent on a core group, this is a large and well connected”

19. Different roles in the network In Figure 5a, the larger nodes indicate that those teachers play an important role as a “b r oker ” in the network by connecting to different clusters of teaches who collaborate within different projects . In Figure 5b, the larger nodes in the project cooperation network indicates that those teachers are part of more projects than the other teachers with the smaller nodes.
