AHA! is a simple Web-based adaptive hypermedia system. Because of this simplicity it has been studied and experimented with in several research groups. This paper identifies shortcomings in AHA! and presents AHA! version 2.0 which tries to overcome the known problems with AHA! while maintaining its biggest asset: simplicity. The paper illustrates…

Describes the Hypertutor Model, a message design framework for interactive instructional systems that emphasizes learner control, presentation, practice, feedback, and learning resources. Problems with software designed for computer assisted instruction are examined; hypertutor systems are discussed; and MegaMentor, a hypertutor system at the…

This article examines the concept of interactivity and discusses human-to-human interactivity versus computer-to-human interaction in education. Levels of communicative interdependence are explained, variables that are important ingredients of interactivity are discussed, learner control is discussed, and two interactive instructional systems are…

Guidelines are presented for the development of computer-based instructional materials. Steps in courseware development defined by M. D. Roblyer (1988) include: (1) instructional design; (2) preprograming development; and (3) programing. The emphasis is on instructional design, the most time-consuming part of the task. Preprograming development…

Presents an approach to computer science teaching developed at the University of Warwick (England), in which students can choose different tools and techniques according to their needs and preferences; the approach allows the system to evolve with advances in technology. Describes the software designed for the automatic submission of assignments…

Provides a framework for selecting a hypermedia authoring system for use in developing interactive computer-based training (CBT). Criteria for analyzing three major functions are explained: learner control, including user friendliness, and online help; information presentation, including the ability to add audio and visual elements; and source…

The Dynamic Courseware Generator (DCG), which runs on a Web server, was developed for the authoring of adaptive computer-assisted learning courses. It generates an individual course according to the learner's goals and previous knowledge, and dynamically adapts the course according to the learner's success in knowledge acquisition. The tool may be…

Argues that including computer programming in the curriculum as a medium for instruction is a feasible alternative for teaching problem solving. Discusses the nature of problem solving; the problem-solving elements of discovery, motivation, practical learning situations and flexibility which are inherent in programming; capabilities of computer…

Arguing that good screen design is an important part of good instructional design for computer-based training, this article describes how to design screens to facilitate learning and provide for appropriate student-computer interaction. Topics discussed include general text and graphics design, screen layout, use of color, and effective design for…

This paper describes a 4-month-long experiment in computer-based learning called Instructional Software Design and presents aspects of the software evaluation. Results included greater mastery of LOGO and fractions by the experimental class than for either control class and greater acquisition of metacognitive skills. (Author/CW)

Presents guidelines derived from cognitive and constructivist learning theory and instructional design literature for designing effective hypermedia-based courseware. Topics addressed include the influence of learning theory, hypertext and hypermedia, courseware design factors, learner interaction variables, practice, feedback, learner control,…

This paper introduces and analyzes problems and issues in the design and use of cognitive tools in open, user-centered learning environments. It introduces a classification scheme for tool functions, and showcases several tools in a current educational hypermedia research and development effort. Information-seeking, information-presentation,…

In research and development it is not unusual to find the resources driving the instruction; this approach can be modified to a more acceptable one if the new technology is applied in such a way as to integrate sound instructional methods. Research and development personnel of the University of Victoria (Canada) Language Center often initiate…

Current literature pertaining to multimedia programs is reviewed and discussed as it relates to the design and development of instructional programs. Most of the literature reviewed covers the last 4 years. Major areas discussed include: (1) instructional (instructional strategies and cooperative learning); (2) branching (navigation and learner…

Describes the design and use of SCORE (Sales and Customer Service Occupational Readiness Education), courseware developed by AT&T to provide midliterate adult customer service representatives with computer-assisted instruction. Topics addressed include job simulations; skills in reading, writing, math, problem solving, and critical thinking;…
