Abstract. The virtual laboratory (VILAB) supports interactive problem solving in computer science with access to complex software-tools. During the problem solving processes the le...
: This paper presents an evaluation study that compares two different problem selection strategies for an Intelligent Tutoring System (ITS). The first strategy uses static problem ...
In this paper we suggest a new approach to analysis and design of IR systems. We argue for design space exploration in constructing IR systems and in analyzing the effects of ind...
As ubiquitous computing technologies mature, they must move out of laboratory settings and into the everyday world. In the process, they will increasingly be used by heterogeneous ...
