AHIS equation describes a new model for instructional system design and develops a system based on Merrill's Component Display Theory incorporating appropriate selection of Media, Ergonomics and Navigation Structures to produce learner engaging and effective learning outcome. A significant component of the proposed model is the integration of…

Curb cuts and automatic doors are a commonplace in the physical world as they provide access to our buildings for persons with disabilities. In the world of the web, millions of individuals have the legal right to rely on electronic curb cuts so they too can access the web. To this end, a new generation of information systems graduates must…

Learning has transcended into a life-long endeavor in the information age. It is no longer restricted to confines of formal classrooms. Consequently, a student is not restricted to traditional learning resources like teachers, textbooks or printed content. Digital resources available on the Internet form a very significant component of…

Advances in the Google Earth virtual globe and the concomitant Keyhole Markup Language (KML) are providing educators with a convenient platform to cultivate and assess one's place location knowledge (PLK). This article presents a general framework and associated implementation methods for the online testing of PLK using Google Earth. The proposed…

This article presents KnowledgePuzzle, a browsing tool for knowledge construction from the web. It aims to adapt the structure of web content to the learner's information needs regardless of how the web content is originally delivered. Learners are provided with a meta-cognitive space (e.g., a concept mapping tool) that enables them to plan…

Typical web lectures consist of two different kinds of media linked together: an audio- or video-recording and the corresponding slides or desktop recording. Both media are synchronized so that the slide or image shown corresponds to the position currently played in the time-based media stream. Web lectures are thus composite media consisting of a…

This article describes how the author applied principles of universal design to hybrid course materials to increase student understanding and, ultimately, success. Pulling the three principles of universal design--consistency, color, and icon representation--into the author's Blackboard course allowed her to change the types of reading skills…

The rapid growth of e-business and e-commerce has made server-side programming an increasingly important topic in information systems (IS) and computer science (CS) curricula. This article presents an overview of the major features of several popular server-side programming technologies and discusses the factors that influence the selection of…

Describes a management system developed by BT Laboratories (United Kingdom) that is based on ISO 9001 using the World Wide Web, a hypermedia system, and part of the Internet. Subject matter is presented as an alphabetical list of linked entries, numerous navigational techniques are available, and searching options function within an index file.…

This paper provides a brief description of Hyper-G, the first second-generation hypermedia system. The first section identifies problems with first generation hypermedia systems. The following sections discuss the new concepts that are implemented in Hyper-G, including user accounts and billing, structuring of data, caching and replication, native…

This paper examines the main issues in hypermedia navigation, proposes research questions, and suggests a methodology for resolving those questions. The paper begins with an overview of navigation and a discussion of design issues in hypermedia databases, including being lost in hyperspace, the use of hypermaps, proper balance between links and…

Describes Microcosm, an open hypermedia system for browsing through large bodies of multimedia information via links in external linkbases; explains HyTime (Hypermedia/Time-Based Structuring Language), an international standard for representing relationships between document objects; and examines HyTime features which are relevant to Microcosm.…

Explains ODA (Open Document Architecture), an international standard for representation and interchange of multimedia documents to support document interchange between document processing systems provided by different vendors on different platforms. Plans for future development are discussed, including HyperODA extensions; and worldwide product…

Offers a redefining of three problem areas associated with the cognitive effects of the semiotic characteristics of hypermedia: hypertext associativity, non-linearity, and the rapprochement of real and hypertext navigation. Focuses on navigation and discusses characteristics of hypermedia and its rapport with knowledge. (Author/LRW)

Personalized adaptive learning requires semantic-based and context-aware systems to manage the Web knowledge efficiently as well as to achieve semantic interoperability between heterogeneous information resources and services. The technological and conceptual differences can be bridged either by means of standards or via approaches based on the…
