Level 1: Social networks of the teacher community and the SE teacher’s position
At the first level, we will present the results from the overall teacher community’s networks describing both actor and network level measurements and especially concentrate on SE teacher’s position. It should be mentioned, in the Table 1 concerning knowledge-sharing network, both an actor’s own estimation (out degree) and that of the alters (in degree) are presented. The results rely; however, only on in degrees that represent the centrality of the actor estimated according to incoming ties that the other community members reported. In the cases of collaboration and informal interaction the networks, and consequently the degree values, are symmetrized. It is typical for SNA that some respondents assess the number of their own network ties as relatively large, which consequently overemphasizes their network centrality. Apparently, in degree values and symmetrized degrees provide a more reliable estimate of a person’s centrality.
