Describes a study conducted at the University of South Carolina that examined the frequency of occurrence of several types of errors in a sample of natural language queries submitted by users requesting online searches in information retrieval systems. Implications for system design are suggested, including parsing systems. (28 references) (LRW)

Discusses software sharing on computer networks and the need for proper bandwidth; and describes the technology behind FidoNet, a computer network made up of electronic bulletin boards. Network features highlighted include front-end mailers, Zone Mail Hour, Nodelist, NetMail, EchoMail, computer conferences, tosser and scanner programs, and host…

Introduces a special issue on research on hypertext systems and information retrieval. Systems design aspects, including navigation models, link weighting, multiple representation techniques, automatic authoring, user modelling, varying levels of abstraction, and evaluation techniques are addressed. (EA)

Discusses instructional design models and examines rapid prototyping, a model that combines computer design strategies, constructivist learning theory, and cognitive psychology. Highlights include limitations of linear models; instructional problems appropriate and those not appropriate for rapid prototyping; and rapid prototyping as a paradigm…

The spectacular increase in Internet-based applications during the past decade has had a significant impact on the education delivery paradigms. The user interactivity aspect of the Internet has provided new opportunities to instructors to incorporate its use in developing new learning systems. The use of the Internet in carrying out live…

The Computing Curricula (2005) place Information Systems (IS) at the intersection of exact sciences (e.g. General Systems Theory), technology (e.g. Computer Science), and behavioral sciences (e.g. Sociology). This presents particular challenges for teaching and learning, as future IS professionals need to be equipped with a wide range of…

Affective commitment and intrinsic motivation to share knowledge are important issues in developing successful technology-mediated learning (TML) and knowledge management (KM) systems. This paper investigates an individual's social/self identities and affective commitment as important identity factors for perceived enjoyment to share knowledge by…

In this paper we present the results of research work, that forms part of the activities of the EU-funded project SLOOP: Sharing Learning Objects in an Open Perspective, aimed at encouraging the definition, development and management of Open Educational Resources based on the Learning Object paradigm (Wiley, 2000). We present a model of Open…

The aim of this survey is to provide an overview of the various components of "computer aided affective learning systems." The research is classified into 3 main scientific areas that are integral parts of the development of these kinds of systems. The three main scientific areas are: i) emotions and their connection to learning; ii) affect…

Learning in complex and ill-structured knowledge domains requires accommodation of multiple perspectives embedded in authentic activities and the reconciliation of those perspectives with personal beliefs resulting in conceptual change. Cognitive flexibility hypertext systems support that process by enabling learners to explore authentic cases…

This article investigates the usability of a navigation support tool, which guides learners by generating advice on the next best step to take in a self-study e-learning course. The article draws on log data and responses from online questionnaires to provide insights into learners' evaluation of the tool, their adherence to the advice and their…

In this paper we will focus on a specific category of Collaborative Virtual Environments that aims to support Collaborative Learning. We call these environments Collaborative Educational Virtual Environments. Our aim is to analyze the evaluation process through the study of relevant bibliography and by doing so reveal the existing research gap…

The present research investigates the contribution of an interactive educational virtual environment on milk pasteurization to the learning outcomes of 40 students in a technical secondary school using SOLO taxonomy. After the interaction with the virtual environment the majority of the students moved to higher hierarchical levels of understanding…

User participation and its relationship to system success have been discussed in the information systems (IS) literature from many theoretical and practical perspectives. In reality, most of this discussion is grounded in empirical research that has yielded mixed results on the importance of user participation and its relationship to system…

It has been recognized that in order to drive Intelligent Tutoring Systems (ITSs) into mainstream use by the teaching community, it is essential to support teachers through the entire ITS process: Design, Development, Deployment, Reflection and Adaptation. Although research has been done on supporting teachers through design to deployment of ITSs,…
