This paper describes the underlying concepts, architecture, and design of a Web-enabled CyberCollaboratory (Web-CCAT) for geographically distributed information systems students and working professionals. The primary objectives for Web-CCAT are (1) to provide the opportunity to participate in and enjoy the benefits of cooperative learning without having to coordinate meeting times or come to campus; and (2) to provide a more technologically enriched collaborative environment than is possible in a traditional face-to-face classroom. To meet these objectives, multiuser , collaborative software tools and procedures were designed for use in the asynchronous mode of communication. Web-CCAT is implemented as a tool kit of commercially available applications coupled with software developed at the University of Illinois at Springfield. The system became operational in January 1999.
