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)

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…

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…

The Collaboratory Notebook, developed as part of the Learning Through Collaborative Visualization Project (CoVis), is a networked, multimedia knowledge-building environment which has been designed to help students, teachers and scientists share inquiry over the boundaries of time and space. CoVis is an attempt to change the way that science is…

Development of online courses requires the use of appropriate educational philosophies that discourage rote learning and passive transfer of information from teacher to learner. This paper reports on the development, use and evaluation of two second year Biology online software packages used by students in constructivist environments. The courses…

Discusses the eight learner attributes of immersion, reflection, play and flow, collaboration, learner control, curiosity, fantasy, and challenge, which were identified as being important in bringing about motivation and engagement in adult learners. Describes the interactive multimedia learning environment, "Principles of Financial Investment,"…

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…

Describes a software shell, STAR.Legacy, designed to guide attempts to help students learn from case, problem, and project-based learning. STAR.Legacy supports the integration of four types of learning environments: learner-centered, knowledge-centered, assessment-centered, and community-centered. Describes how a STAR.Legacy constructed for an…

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 proceedings of the 1993 convention of the Association for Educational Communications and Technology (AECT) contains 70 papers and 1 symposium. Topics addressed by the papers include computer-based mapping for curriculum development; educational technology equipped classrooms; individual characteristics influencing learning; network resources…

It is increasingly necessary to encourage lifelong learning in order to keep pace with the Information Age. As learners increasingly take charge of their own learning, however, they will require support to enable them to achieve their goals--and a variety of learning opportunities will need to be created. Learners' interests, imagination, and…
