The advanced learning internet technologies indicated a need for methodologies, tools and pedagogues that support the introduction of synchronous e-learning applications and especially Interactive Videoconferencing (IVC) into the whole learning environment. This book presents the theoretical background and the methodology that have been developed, to implement a pedagogical model for IVC instruction. The proposed pedagogical model constitutes the results experienced from an IVC project in the University of Crete during the last seven years, under the title 'ODUSSEAS', which took place between eight hundred students and thirty teachers in eighteen elementary schools in Greece and Cyprus.
