Presents a framework for the study of hypertext. First, a historical perspective on the evolution of hypertext is provided. Next, hypertext system components are presented, and relevant psychological and pedagogical issues are analyzed. Finally, a framework for the study of hypertext, with implications for theory, research, and development, is…

If learners are to engage in science inquiry, they need significant support, or scaffolding, to help them mindfully do the cognitive science tasks that are just out of their reach. One approach for supporting learners is to design computational tools that incorporate scaffolding features to make new practices accessible and visible so learners can…

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…

Discusses three factors that have particular relevance for the designers of instruction for adult distance learners: (1) support for learner control; (2) access to different levels of interaction; and (3) availability and ease of use of different technology platforms. Topics include motivation for change and the design of courseware. (Author/LRW)

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…

The program demonstrated in this paper, "The Classroom Behavior Record: School Version," is an alternative approach for training personnel in observational skills, designed for educators and health care professionals. The purpose of the program is to provide efficient and effective training in a flexible, learner-centered, hypermedia format. The…

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…

Discusses procedures for storyboard development and provides guidelines for designing interactive multimedia courseware, including interactivity, learner control, feedback, visual elements, motion video, graphics/animation, text, audio, and programming. A topical bibliography that lists 98 items is included. (LRW)

Novices in programming face many problems affecting their learning process and programming success. Learning to program includes using the programming environment, learning a programming language's syntax and semantics, understanding a problem and translating it into an executable plan, developing algorithms and programs, and testing and debugging…

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…
