What's the difference between CHALLENGE and WebCT?

Note: The CHALLENGE Suite (with the exception of CHALLENGE FRAP) has been discontinued.  This is an archive site which describes CHALLENGE as it was between 2002 and 2004 for historical purposes.  See this link for further information.  The PBL work now continues with this project (Terry Stewart - 23rd June, 2005)

As I've been receiving feedback on CHALLENGE it's come to my attention that people invariably seem to compare it to WebCT. The two products can complement each other but they are two very different things. WebCT is a Virtual Learning Environment which incorporates a series of tools for delivering course materials over the web.  CHALLENGE is an authoring and delivery tool designed to author and present, problem-based scenarios via computer.  

These scenarios, FRAP forms and the CHALLENGE player, can be delivered to students over the web  using a WebCT learning environment. In this case, students would download them from a WebCT site, install them in their machines and upload (or email in) their reports.

One might ask "Can't problem-based scenarios simply be written as a series of webpages, and delivered from the WebCT server for viewing in the browser"?  The answer is yes, just as problem-based scenarios can be written on paper or a white board.  However, for complex scenarios CHALLENGE has advantages over a more linear method of presentation.  These can be summarised by the table below:
