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…

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…

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…

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,…

Researchers have claimed that while educational computer software does not necessarily improve students' academic performance, it does provide for students a more interesting and motivational environment for learning. It naturally fits in the context of students' learning since it can deliver nonstop actions, realistic sounds and vivid colors to…

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…

This paper presents a model for designing computer-based simulation environments within a constructivist framework for the K-12 school setting. The following primary criteria for the development of simulations are proposed: (1) the problem needs to be authentic; (2) the cognitive demand in learning should be authentic; (3) scaffolding supports a…

Pressure to make graduate study in Australia more responsive to individual learner needs and autonomy is discussed. It is proposed that in this context, three groups of individuals will have important roles: those involved in institutional administration; educational technologists and computer software designers; and teachers. Those evolving roles…

A difficult task in creating rich, exploratory interactive learning environments is building an environment that is truly engaging. Engagement can be defined as the nexus of intrinsic knowledge and/or interest and external stimuli that promote the initial interest in, and continued use of a computer-based learning environment. Complete and total…

This paper describes an alternative delivery approach for training personnel in observation skills using interactive multimedia technology. The "Classroom Behavior Record (CBR) Observation Training Program," includes three videodiscs that contain video and audio scenes of children in classrooms/playgroups and instructional narrations.…
