The study was carried out in an upper comprehensive school in a suburban area of Helsinki, Finland. I n the study, all 33 members of the school’s teacher community took part, including 29 teachers, a principal, 2 school assistants and a school secretary. The participants were asked to respond to a Social Network Analysis (SNA) questionnaire designed to assesses networking relations among the participants according to the following five dimensions: 1) providing technical advice regarding ICT, 2) providing pedagogical advice for using ICT, 3) collaboration regarding web-based learning, 4) acquiring new knowledge or ideas of web-based learning, 5) informal interaction between the members of the community. In addition, the use of different kinds of media and teachers’ other information sources were analyzed. The results of the study indicated that the members of the community differed in terms of ICT-related networks and informal interaction. There were a few central actors in the community, who dominated technical and pedagogical information exchange and to whom their colleagues actively turned in their advice-seeking. Two of the cognitively central actors represented hybrid expertise, a characteristic of which was to merge technological and pedagogical expertise in using ICTs in education. These actors tended also to have their own external networking relations that helped them to keep up their high level of competence. The participants’ ICT-related egocentric network differed in size and density. There were some actors central in the network of informal interaction who were, simultaneously, peripheral in ICT-related networking activities. On the other hand, the central actors of ICT were not necessarily the socially central persons in the community. In the analysis investigators identified four distinct, personal patterns of networking, represented by four teachers; The Counsellor offers advice actively without herself seeking information from colleagues; The Inquirer is an active seeker of ICT-related information through capitalizing on her social relations; The Collaborator engages in collaboration efforts of webbased learning by using several media; and The Weakly Social prefers media rather than face-to-face contacts in his information seeking. Other members of the teacher community were more or less mixtures of these four types. The use of media in relations of information exchange of ICT was a complex phenomenon, which was strongly related to the actors’ personal egocentric networks and the quality and the content of a tie. The use of media explained members’ individual ways of carrying out interaction with others, and the different kinds of actors appeared to have personal media profiles. The results of the study indicate that SNA can productively be applied to examine networking relations within a teacher community.
