Taking Control

Abstract

Libraries are at a crossroad. Down one road are the traditions long accepted by libraries as the proper way to run a library. The other way leads the libraries into the challenges and chaos of the Internet. There are innovative attempts to use the potential of the Internet to redirect traditional patterns of access to information and services.     

CD-ROM Integration Peaks Student Interest in Inquiry

Summary

Members of the faculty of educational science and technology of the University of Twente, The Netherlands, have been making innovative use of WWW-based course-support sites since 1994. By 2000 all of the faculty were involved not only in using the WWW, but also more fundamentally in a new educational approach. In addition, our educational technologists collaborate with other faculties to support the same progression. How has this come about? In this article, the TeleTOP Method (http://teletop.edte.utwente.nl) is described, showing how it has developed based on an implementation model and experience acquired with innovative use of the WWW for course support. The applicability of the model to other faculties and settings is discussed.
