The Virtual University is an Internet-based learning environment developed at the University of Hagen (Germany). Complex teaching activities based on new concepts integrating net-based communication and cooperation facilities take place in the Virtual University. Experiences show that there is a threshold, especially for tutors in non-computer science fields, in using the new technologies for tutoring activities. The problem is that they have to arrange completely new organizational processes and manage the new technology. In order to ease the tutor's work, a net-based tutoring concept incorporating both organizational and technical support for tutors is being developed. This paper demonstrates the concept of a net-based tutoring wizard as a model for the management of virtual seminars. Topics discussed include: (1) concepts and problems of traditional and net-based tutoring; (2) characteristic functionalities of a tutoring wizard, including templates for World Wide Web-based tutoring, automatic generation of Web pages on the basis of the tutor's information filled in dialog boxes, support for publishing and changing information on the Web server, task management, notification mechanism, support of tutor groups, and integration of workflow aspects; and (3) implementation of a tutoring wizard prototype using Microsoft FrontPage. Four figures present sample screens. (Author/DLS)
