Now days the growing need for highly qualified computer science educators in modern educational environments is commonplace. This study examines the potential use of Greek School Network (GSN) to provide a robust and comprehensive e-training course for computer science educators in order to efficiently exploit advanced IT services and establish a modern and versatile education environment in the Greek Society. Furthermore, a preliminary questionnaire survey was performed in order to validate the adoption of GSN and also to formulate a realistic training course customized to specific and future needs of computer science educators in primary and secondary education, thus enabling them to immerse in real-world situations (i.e., school computer laboratory). Findings from this preliminary survey are also presented. [For the full proceedings, see ED562127.]
