I was today in Karlsruhe at Learntec, a trade fare and congress for technologies in learning, training and education. Alois Ferscha organized a session on pervasive computing and learning.
My talk was entitled "back to the roots – technologies for interweaving learning and experience". I stared out with the question: What is the difference between an apple tree and a biology book. In essence my argument is that (1) first hand experience can not be replaced, (2) we need consolidated knowledge based on the experience to learn efficiently, and (3) pervasive computing technologies can bridge the gulf between them.
The slides of the talk “Zurück zum Ursprung - Technologien für die Verflechtung von Lernen und Erfahren” (in German) are available on my web page.
