In recent years a methodology for Courseware design together with a number of Web based courses have been developed at Cardiff. A variety of disciplines have benefited notably C programming, X Window/Motif programming, Computer Vision, Image Processing, Computer Graphics, Artificial Intelligence and Parallel Computing. The range of provision of on-line support included access to lecture notes, exercises and their solutions to more interactive packages suited primarily for teaching and demonstration packages.This last academic year a totally new course, Internet Computing, was introduced as a first year undergraduate course at the University. This paper details the implementation of this new course within the courseware design methodologies already developed at Cardiff. In particular, it highlights some interactive features used to illustrate parts of the course and also how automated feedback and marking have been incorporated into the courseware.
