Social networks make an essential contribution to knowledge sharing in our fast moving and changing world. However, it is difficult to apply new techniques to the complex, firm and Europe-wide differing educational systems. And this process for technology enhanced learning is still evolving and challenging. This paper presents the research results of applying social network analysis methods to a real and lively social network which intends to enhance the cooperation and knowledge sharing among over 45,000 European schools within the eTwinning network. We developed a web-based tool for network analysis and the visualization of various network views and data mining results as proof of concept. This prototype is evaluated on the educational social network eTwinning coordinated by the European Schoolnet, with special regard to its network structure and collaboration activity.
