This research examined the impact of the length and format (video, audio or text) of instructional Web modules (segments of lectures) on information recall, persistence, perceived content difficulty, aesthetic appeal, and perceived module length. Twelve Web-based instructional modules with different formats and lengths were evaluated through an…

Tools to support knowledge elicitation are used more and more in situations where employees or students collaborate using the computer. Studies indicate that differences exist between experts and novices regarding their methods of work and reasoning. However, the commonly preferred approach tends to deal with team members as a single system with…

There is a gulf between the rhetoric of those advocating the use of ICT in education in Africa and the reality of classroom practice. This paper explores some of the reasons for this, and outlines a possible framework for the successful implementation of teacher training programmes that make advantageous use of appropriate ICTs. It argues that six…

This article examines some of the ways graduate students engage in interactive writing in online university courses as a means of discussion. In particular, I present data from course transcripts that suggest that discursive interaction in an asynchronous, text-based, online course may be uniquely suited to fostering higher-order thinking and…

Business organizations are increasingly adopting collaboration tools to increase communication within the firm. CAMS is a home-grown online collaborative environment which makes heavy use of participant's pictures. Participants, both faculty and students, were asked questions about the benefits and usefulness of pictures in the CAMS collaborative…

Generating true learning dialogue as opposed to a collection of loosely affiliated posted messages on a class discussion board can be challenging. This paper presents the results of a cross-case analysis of nine naturalistic case studies of online classes, looking at how activity design and facilitation factors affected various dimensions of…

In post-industrial societies saturated with the multimodal texts of consumer culture--film, computer games, interactive toys, SMS, email, the internet, television, DVDs--young people are developing literacy skills and knowledge in and for a world significantly changed from that of their parents and educators. Given this context, this paper seeks…

The University of Texas at Arlington's Library began using an online chat reference in 2002. The service, called Collaborative Digital Reference Service, later became "Ask a Librarian." Slightly over one year later, the library joined the University of Texas System's "Ask a Librarian" service. Both services are powered by…

Purpose: Aims to investigate the way that the semantic web is being used to represent and process social network information. Design/methodology/approach: The Swoogle semantic web search engine was used to construct several large data sets of Resource Description Framework (RDF) documents with social network information that were encoded using the…

This article presents a sketch for a theory of the rhetorics involved in categorisation and the creation of culture in online communities. Persuasion, or shaping perceptions of the world, is never incidental to social life, but living online necessarily involves persuasion as it is difficult to bring force to bear, although people can be…

Collaborative work is an important part of tertiary education but it is very difficult to arrange and supervise for extremely large classes of students in their first year. The possibility that computer-mediated communication can be used to facilitate this type of learning is appealing from a pragmatic organisational point of view. This paper…

Two experiments investigated if and how visual representation of interactants affects depersonalization and conformity to group norms in anonymous computer-mediated communication (CMC). In Experiment 1, a 2 (intergroup versus interpersonal) x 2 (same character versus different character) between-subjects design experiment (N=60), each participant…

The assessment of learners' metacognitive knowledge level is crucial when developing computer-assisted language learning systems. Currently, many systems assess learners' metacognitive knowledge level with pre-instructional questionnaires or metacognitive interviews. However, learners with limited language proficiency may be at a disadvantage in…

This study investigates gender differences in Internet use by Greek high school pupils within school and out of school environments. A sample of 340 pupils (170 boys and 170 girls), aged 12-16 years, completed a written questionnaire on their attainability, location, frequency and purposes of Internet access. The data analysis showed that more…

This paper reports findings from a study of undergraduates' expectations about, and experiences of, networked learning using computer-mediated conferencing (CMC). The data come from questionnaires administered at the start and end of four different courses, and their interpretation is informed by a set of interviews with students and teachers…
