CADMOS: an approach to developing Web-based instructional systems

The educational use of the Internet and the World Wide Web has grown enormo usly over the last few years and continues to grow at a tremendous rate. In structional systems, based on these networked technologies, have been const ructed to solve instructional problems. There is evidence that these system s efficiently support the instructional process. Instructional developers s hould follow effective and quality driven development methodologies, which are specifically developed to support the development of network-based inst ructional systems. This article presents a methodology, CADMOS, which accor ds to the principles of the third and partially the fourth generation of In structional Systems Development (ISD). The main innovation of CADMOS is its advocacy on splitting an instructional system into four sub-systems: human , webware, other learning resources, and specific infrastructure sub-system s.
