چکیده (انگلیسی):

The educational use of the Internet and the World Wide Web has grown enormously over the last few years and continues to grow at a tremendous rate. Instructional systems, based on these networked technologies, have been constructed to solve instructional problems. There is evidence that these systems efficiently support the instructional process. Instructional developers should follow effective and quality driven development methodologies, which are specifically developed to support the development of network-based instructional systems. This article presents a methodology, CADMOS, which accords to the principles of the third and partially the fourth generation of Instructional 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-systems.
