This paper discusses problems concerning the design of educational applications in general, as well as specific problems connected with educational applications meant to be published on the Web. A new approach to the authoring and maintaining of Web-based educational applications is proposed which is based on the concept of hypermedia composites.…

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…

Discusses downloadable executable content, or mobile code, on the World Wide Web; evaluates the security features offered by the Java and Safe-Tcl programming languages; and describes the basic mechanisms of each of the proposed security models. Presents current implementations, as well as upcoming extensions, and evaluates their efficiency and…

One of the problematic issues in the content development for learning environments is the process of importing various types of course material into the environment. This paper describes a method for importing material into the A&O open learning environment by introducing a material model for metadata recognized by the environment. The first…

This paper describes a methodology for use in teaching an introductory Database Management System (DBMS) course. Students master basic database concepts through the use of a multiple component project implemented in both relational and associative data models. The associative data model is a new approach for designing multi-user, Web-enabled…

Recently, platform independent software components, like JavaBeans, have appeared that allow writing reusable components and composing them in a visual builder tool into new applications. This paper describes the use of such models to transform an existing course into a modular construction kit consisting of components of teaching text and program…

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…

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…

Engaging learners on the World Wide Web is more than sending Web pages to the user. However, for many course delivery software programs, the smallest unit of delivery is a Web page. How content experts can create engaging Web pages has largely been ignored or taken for granted. This paper reports on an authoring model for creating pedagogically…

This book examines human-computer interaction (HCI), with a focus on designing computer technology to be more usable by people. The book provides a multi-disciplinary approach to the subject through a synthesis of computer science, cognitive science, psychology, and sociology, and stresses a principled approach to interactive systems design that…

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…

The construction of a very fast network backbone between all Scottish universities, in conjunction with the formation of a common core curriculum for Scottish medical schools teaching child health, has provided the schools with an opportunity to provide collaborative, computer assisted learning (CAL) across the World Wide Web, delivered by a…
