An adaptation technique of multimodal interfaces based on a cognitive modeling of users is presented in this paper. The adaptation process tries to select a combination of modalities that best fits the cognitive profile of each user. This profile contains indicators of cognitive abilities and styles. This paper focuses on output modalities and…

Discusses the design and maintenance of computer-based teaching and learning environments and illustrates consequences of evolution and change in Web-based courses. Focuses on changes in content; format of the course; infrastructure, including hardware, systems, and software; and pedagogy, or instructional design, including knowledge modeling,…

Describes ECAL (extended computer-assisted learning) which was designed to incorporate artificial intelligence ideas to extend traditional CAL tools. Intelligent tutoring systems are discussed; authoring tasks in CAL and intelligent computer-assisted instruction (ICAI) are described; and the general architecture of the system is explained. (8…

Based on previous research, this article describes an attempt to combine a traditional computer-based training (CBT) approach with intelligent computer-assisted instruction (ICAI) to create training materials. Hardware and software configuration of the Eurobench Workstation is described and courseware generation is discussed. (eight references)…

Discusses some of the major aspects of authoring hypertext documents and databases as forms of interactive instruction. Highlights include knowledge structuring; root documents; authoring tools; screen formats; computer graphics; collaboration among authors; cognitive processes; and degree of learner control. (LRW)

Describes an artificially intelligent multimedia computerized instruction system capable of developing a conceptual image of what a student is learning while the student is learning it. It focuses on principles of learning and adaptive behavioral control systems theory upon which the system is designed and demonstrates multiple user modes.…

Provides an overview of issues concerned with the design and use of computer-based simulations. Learning processes are discussed, and the SIMULATE project, which was developed to design an integrated set of authoring tools for the construction of an intelligent simulation learning environment (ISLE), is described. (15 references) (LRW)

Discusses the integration of instructional science and computer science. Topics addressed include motivation for building knowledge-based systems; instructional design issues, including cognitive models, representing student intentions, and student models and error diagnosis; representing tutoring knowledge; building a tutoring system, including…

Explains hyper-systems and discusses their role in active learning, presents results from an expert evaluation of current hyper-systems that use HyperCard, and suggests implications for designers of educational hypermedia. System criteria discussed include purpose, domain or content, structure, navigation methods, control mechanisms, and style of…

This letter to the editor favorably comments on an article by Jerry Willis and Kristen Wright, "A General Set of Procedures for Constructivist Instructional Design: The New R2D2 Model" ("Educational Technology, March-April 2000). The writer notes that though the article's purpose is to describe an alternative to the conventional ISD model, it also…

Reviews research describing computer functions of construction-oriented computer environments and evaluates their contributions to students' learning of geometry. Topics discussed include constructing geometric concepts; the use of LOGO in elementary school mathematics; software that focuses on geometric construction; and implications for the…

Discusses systems dynamics (SD) and considers the types of learning environments that can be designed on the basis of SD models. Highlights include social systems theory; classical systems theory and autopoietic systems theory; models of social systems; computer-based learning environments; simulation modes; and participative design of interactive…

The popularity of web-based learning systems has encouraged researchers to pay attention to several new issues. One of the most important issues is the development of new techniques to provide personalized teaching materials. Although several frameworks or methods have been proposed, it remains a challenging issue to design an easy-to-realize…

This paper reports on research to investigate design features of asynchronous discussion systems for higher education. The research aims to identify features that increase the benefits of discussion systems and reduce the problems. The paper focuses on a major theme that emerged from interviews with learners and teachers: information overload.…

Extracting and applying lessons from history is rarely easy and sometimes risky but there are moments when historical records are so compelling that they rise above mere proof to the level of interocular impact. In this article, the author shares his similar experience while visiting his colleague, Professor Bruce Clark, at the University of…
