The use of computers to provided an integrated environment for teaching a variety of disciplines has received much attention in recent years. Indeed many frameworks [10][6][3] have been developed for such purposes. The material provided by such courseware varies a great deal from the provision of lecture notes and lecture support material through to integrated and interactive tutorial packages. Until recently courseware has existed as stand alone packages [10][3], however with the advent of the World Wide Web (WWW) [4] on Internet and accompanying WWW (hypertext) browsers, such as Mosaic [8], the provision of courseware has taken on a new dimension.
