This study investigated the problems of inefficiency that school technology coordinators (STCs) face in ICT integration instruction by examining their social networks of knowledge sharing. The authors conducted an ego-centric network survey of school technology coordinators' knowledge sharing to explore their brokerages work in exchanging knowledge with colleagues from different positions. The findings revealed that STCs rarely acquired the municipal help of ICT integration instruction. The dissemination of ICT integration instruction practices lacked brokerage pathways. STCs in exemplary schools of ICT-integration instruction had more opportunities to liaise with STCs of other schools regarding ICT practices relative to similar opportunities regarding ICT-integration instruction. STCs are "representatives" who can put technician staffs of their respective schools in touch with STCs of other schools through technology knowledge exchange. This study provides quantitative evidence from social network analysis to answer why STCs have not received the necessary support for them to be effective. Strategies are needed to encourage STCs in exemplary schools to share knowledge to STCs of other schools. Educational administrators should increase or create the institutional supports for practices of ICT integration instruction.
