Abstract

In our research, we synthesize two lines of development that have been dealt with independently so far: 1) the development and evaluation of educational technologies to support problem-oriented and collaborative learning activities inside and outside of the classroom, and 2) interaction design patterns as a means to document and generate design knowledge. Primary contributions are software prototypes for enhancing classroom interaction through interactive whiteboards, multiple clients with pen-tablets and PDAs, and a basic layout of a pattern language for formal and informal learning environments. © Springer-Verlag Berlin Heidelberg 2007.
