The challenge to offer more than a traditional classroom extended over space constitutes the background for the design of the "teleteaching classrooms" that were installed during this project. The design aims to include innovative learning concepts that are student centered, allow to select the appropriate technology according to content and context and support peer-to-peer as well as teacher-student interaction. The real ubication of the electronic resources as well as the participants in the respective scenarios remain transparent for the end user. AGI-Teleteaching is part of the "Galician Network for Science and Technology" (RECETGA), which is based on the ATM network maintained by CESGA.
