In the paper we discuss the application of an expert system as an interactive multimedia knowledge module with explanation features, named Virtual Tutor (VT). The evaluation results and redrawn conclusions are presented. The idea of VT was influenced by the research of [Stil 1998] [Maurer 1992] [Lennon 1994] [Elliot 1995] [Colbourn 1995] [Reeves 1997] [Lugner 1997]. The individual dialogue based session with the VT makes it possible for students to experiment and ask various questions with no fears to fail, similar to little children where trial and error is part of their learning process. The interaction and work with the VT provides the possibility to acquire knowledge parallel and in combination with static and dynamic contents. The VT was further embedded in the Web-based on-line learning environment GENTLE [Hyperwave] and applied for the lecture "Knowlede Processing" at Graz University of Technology. The research reported merges qualities of an expert system with advantages of multimedia, thus creating a variety of innovative ways of knowledge mediation. A user survey was conducted and discussed in brief evaluating appliances of the VT within the lecture "Knoweldge Processing". Based on the evaluation results the conclusion can be drawn that dialog based system meets more accurate the requirements of the students in case of solving problems. Problem solution can be found easier and faster than using conventional literature. The possibility of accessing additional information related to the subject domain and explanation on request, VT is an interesting and different tool for knowledge transfer. The interactivity and explanation feature makes VT a useful tool for the knowledge acquisition in business, especially for the education of professionals.
