A Multimedia Knowledge Module Virtual Tutor Fosters Interactive Learning

For students, the individual dialogue-based session with the VT provides the possibility to apply the knowledge acquired in combination with indirect assessment. The VT was further embedded in the web-based online learning environment. The application of expert systems makes it possible to use different knowledge representation and explanation approaches. Independent from the course content, the web-based online learning environment gives support to the students in various ways, such as tools for asynchronous and synchronous communication and collaboration, a search facility within a background library, and so forth.
