ABSTRACT
This chapter examines several recently developed computer-aided instructional design systems. Instructional design theories attempt to specify the space of instructional situations, to identify the space of instructional methods, and to develop statements, called principles. Prescriptive principles are the kind of statement used in design to identify the optimal method to use in a given situation. Instructional Design Environment (ISD) Expert is a prototype expert system intended for use as a consultation system by inexperienced instructional designers. It is in part dependent on a frame-based representation of various types of content structures, course organizations, strategies, and transactions. In contrast to ISD Expert and Expert CML the Instructional Design Environment (IDE) centers on experienced users driving their way through the system. IDE is a hypermedia system in which instructional designers can enter, edit, and manipulate their analyses and specifications.
