Educational television

From educational television towards mobile, active acquisition of skills in meaningful contexts.


The museum as education center: active learning with virtual exhibits, also for collecting and sharing.

Technology Enhanced Textbook (TET)

The Technology Enhanced Textbook as a mobile, interactive textbook supports its future user with didactic, technological extensions of reality, through a high degree of content modularity and by a variety of tools for individual and joint construction of knowledge. TET adds new approaches of interacting with the environment to established concepts of the textbook: interactive media modules enable experimentation and exploration in locations and in situations that are not available in reality.
