“…By``educational multimedia database'' we mean a computer system that can store multimedia learning objects, allow a person to search through the collection of learning materials and retrieve learning objects. There are many definitions of``learning objects'' (Persico et al, 1992;Olimpo et al, 1990;Chalon, 1994;Rada, 1995); for our model it does not matter much which definition is chosen. The fact that the learning material is stored in a database that allows search and retrieval enables the reuse of learning materials; there are many factors, however, that may inhibit or reduce the reusability of these learning materials.…”

Observes that the widespread use of the World Wide Web for educational purposes creates many opportunities for reusing learning material. However, many factors are involved that may decrease the amount of actual reuse that occurs. Presents a theoretical model of these factors, one of which is the physical layout of learning objects. Approaches this problem by separating the layout of learning objects from their content. This is achieved by describing the content in the eXtensible Markup Language (XML) and the layout in the eXtensible Stylesheet Language (XSL). The architecture of a prototype is presented showing how this technology can be used in an online learning environment.

“…It adopts an intermediate solution between authoring environments that include all necessary tools in their architecture (tools of this kind are described in Otsuki and Takeuchi (1985); Mispelkamp (1992); Wallsgrove (1992)) and those that provide a platform for integration of other existing tools (such as Derks and Bulthuis (1992); Philips and Nuns (1992)). Development of a training application using the former is usually pedagogically-driven, while the latter place emphasis mainly on the reusability of intermediate courseware products of different complexity levels (Olimpo et al, 1992).…”

This article presents the functional architecture and the interaction model of GENITOR, a generator of Intelligent Tutoring Systems (ITSsj. The major design issues that arise during the functional design and development of an ITS-generator concern the provision of mechanisms capable of supporting the description of the teaching subject domain and the specification of pedagogical features of the ITSs that it produces. The system described in the article provides ready-to-use yet flexible solutions for the instructional features of the developed ITSs. In this way, authors can concentrate on the compilation, description, and design of training material that relates directly to their area of expertise. Interaction between GENITOR and authors has been designed using IDFG, an interaction model that supports the representation of multiple aspects of interaction, including data flow, control flow, and task decomposition. As a consequence of using this model, the tasks that make up the authoring process are visualized by a number of authoring tools that are grouped into three subsystems: the reusability subsystem, the authoring subsystem, and the execution subsystem. The functionality of these subsystems and the tools they contain are described, as well as interaction with the overall system. Finally, conclusions drawn from the development of two ITSs using the system are presented in order to validate the design. 0 1997 by Elsevier Science Inc.
