Describes a theoretical model of stages in the comprehension of a machine from diagrams and accompanying text, and considers the implications of this model for designing hypermedia manuals that explain how machines work. Reports on three experiments with undergraduates that evaluated hypermedia and multimedia manuals based on this model.…

Presents a framework for organizing research and theory in the areas of psychology, pedagogy, and technology as they relate to interactive multimedia; and derives principles and implications for the design of interactive multimedia. Highlights include prior knowledge, the organization and utilization of knowledge, feedback, concept maps, and…

This paper describes the ongoing project EONT--Experiment in Open and Distance Learning using New Technologies. The main objective of the project is to examine whether ODL using new technologies is effective. EONT will achieve its goals through experimentation, using an ODL environment based on some of the available new technologies (i.e.,…

This paper describes an approach for developing adaptive electronic textbooks and presents InterBook, an authoring tool based on this approach which simplifies the development of adaptive electronic textbooks on the World Wide Web. The following topics are discussed: (1) content structuring, including the domain and user models, the glossary, and…

Examines a design model for hypermedia materials and gives direction in the development of course support materials for teacher education. Describes design guidelines for matching hypermedia activities to instruction goals and presents results of pilot test conducted in support of methods. (JKP)

Chronicles the effect of using a hypermedia learning (HL) model for graduate students to learn about hypermedia authoring for the creation of computer-based instruction (CBI). The model details how students feel and act in each of the five sequential stages: dependent, interested, involved, engaged, and independent. It also specifies expected…

This paper presents aspects of modeling, authoring, and presenting structured documents corresponding to teaching material presented in the World Wide Web. In this context, the importance of providing the formalization of the structure of the documents using Standard Generalized Markup Language (SGML) is discussed. Next, specifications for…

This paper presents an approach for developing flexible Hypermedia Learning Environments (HMLE) and applies this theoretical framework to the creation of a layered model of a hypermedia system, called HyperDisc, developed at the German Institute for Research on Distance Education. The first section introduces HMLE and suggests that existing…

Discussion of the educational effectiveness of textbooks focuses on a model of a virtual textbook that relies on hypermedia. Highlights include changing roles of teachers, students, and content; systemwide features of the virtual textbook, including interface and object-oriented design; classroom environment; sequencing; and a prototype. (Contains…

This paper proposes a framework for supporting the authoring process of distance learning courses. An overview of distance learning courses and the World Wide Web is presented. The proposed framework is then described, including: (1) components of the framework--a hypermedia design methodology for authoring the course, links to related Web sites,…

This paper describes the electronic ACT-R Bookshelf, a system which supports learning ACT-R, a well-known theory in the field of cognitive psychology, over the World Wide Web. ACT-R Bookshelf is a collection of electronic books on various aspects of ACT-R. The primary role of ACT-R Bookshelf is to serve as a 24-hour information resource for…

Interactive multimedia (IMM) and problem-based learning (PBL) are both promoted in response to the current need to offer authentic and effective professional education. An emphasis on collaborative work in PBL contexts may have discouraged the application of IMM, more commonly designed for individual use. This paper describes preliminary…

The accessibility of the World Wide Web and its flexibility for conveying digital information in various forms makes it a convenient mode of communication for education. With the help of a distance learning application called "Easy Ed," this paper demonstrates how these properties of the Web along with a data model can be used to provide…

This paper presents a framework for producing learning environments (LEs) on the World Wide Web that improves productivity and quality at a reduced cost for both designers and learners. The resulting LEs are germane to fractals. Changes in scale are likened to levels in LEs; each level expresses a given viewpoint on knowledge. Self-similarity…
