The process that accompanies the decision to make an institutional commitment to new ways of teaching and learning supported by a WWW-based course management system is complex. Such a process is underway in the Faculty of Educational Science and Technology at the University of Twente in the Netherlands via its TeleTOP project. A model was needed to guide the change process. In this paper, the development of the first version of the TeleTOP Implementation Model is described and an exploratory study of the generalizability of the model to other settings is reported upon. The general conclusion of this preliminary investigation is that the model appears to be generally applicable in other institutional contexts also involved in systematic change processes involving WWW-based course management systems, but that some revision of the model is needed. Based on the preliminary exploration study, an introduction to version 2 of the model is presented here.
