This paper addresses some of the challenges and dilemmas faced by two instructional designers as they incorporated visual imagery and audio components into the design of two distinct interactive multimedia products. Each instructional product was designed as a professional development seminar or series of instructional seminars for two distinctly…

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 introduces a new application called multimedia annotation, currently being developed in the European Union-funded project DIANE. A system for instant multimedia authoring, with special features for supporting the creation of multimedia documents in a distributed working environment such as distance education, is described. The system…

Topics of the Proceedings of the 15th Annual Computers in Libraries Conference (March 15-17, 2000) include: Linux and open source software in an academic library; a Master Trainer Program; what educators need to know about multimedia and copyright; how super searchers find business information online; managing print costs; new technologies in wide…

Most campuses, recognizing the important role that student services play in learner success and retention, have a full range of student services in place to support their on-campus learners. Yet, many have failed to provide the same level of service to their off-campus learners who cannot come to campus. All students deserve access to a full array…

Presents the Virtual Reference Desk project, its activities, and a proposed information system architecture to build a human intermediated network of expertise and experience. The project seeks to study, support, and improve current K-12 digital reference services, as well as to build a foundation for a national cooperative digital reference…

The race is on to survive the competitive educational market which nearly everyone can now access with the click of a mouse. Many institutions are turning to DETs to tap into this market. The difficulty is evaluating the effectiveness of these tools and the education that is provided by them. Implementing a new DET is neither a simple matter nor a…

The Reflective Tutorial Dialogue System (ReTuDiS) is a system for learner modelling historical text comprehension through reflective dialogue. The system infers learners' cognitive profiles and constructs their learner models. Based on the learner model the system plans the appropriate--personalized for learners--reflective tutorial dialogue in…

In this paper we describe the ways that SCoT, a Spoken Conversational Tutor, uses flexible and adaptive planning as well as multimodal task modeling to support the contextualization of learning in reflective dialogues. Past research on human tutoring has shown reflective discussions (discussions occurring after problem-solving) to be effective in…

The role of conceptual modeling in Educational Adaptive Hypermedia Applications (EAHA) is especially important. A conceptual model of an educational application depicts the instructional solution that is implemented, containing information about concepts that must be ac-quired by learners, tasks in which learners must be involved and resources…

Computer-based testing (CBT) is typically implemented using one of three general test delivery models: (1) multiple fixed testing (MFT); (2) computer-adaptive testing (CAT); or (3) multistage testing (MSTs). This article reviews some of the real cost drivers associated with CBT implementation--focusing on item production costs, the costs…

This paper describes a system called ANDES, designed for the management and delivery of distance education courses. ANDES enables students to study at home at their own pace, as well as interact with instructors and other students in virtual classrooms. It uses World Wide Web technology for transmission and delivery, with extensions relevant to…

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 author analyzes properties of mutual information between dichotomous concepts and test items. The properties generalize some common intuitions about item comparison, and provide principled foundations for designing item-selection heuristics for student assessment in computer-assisted educational systems. The proposed item-selection strategies…

This paper presents a reference framework to describe educational material. It introduces the PALO Language as a cognitive based approach to Educational Modeling Languages (EML). In accordance with recent trends for reusability and interoperability in Learning Technologies, EML constitutes an evolution of the current content-centered…
