This paper presents a quantitative approach to multimodal discourse analysis for analyzing online collaborative learning. The coding framework draws together the fields of systemic functional linguistics and Activity Theory to analyze interactions between collaborative-, content- and technology-related discourse. The approach is used to examine…

This paper reports on the uses of interactive whiteboards in "connected classrooms" in rural New South Wales, Australia. The research specifically focuses on the e[superscript 2] program, a senior school initiative among five schools that seeks to extend the range of curriculum options available for students by connecting classrooms…

Analyzes requirements for text-based online conferencing through the use of a minimal prototype. Topics discussed include prototyping with a minimal system; text-based communication; the system as a message passer versus the system as a shared data structure; and three exercises that showed how users worked with the prototype. (Contains 61…

Introduces an extension of the Session Initiation Protocol (SIP) for closed multiparty conferences; the extension expands SIP for discovery of participant identities in a conference, and ensures that each participant is notified before a new participant joins. Verifies this extension by applying it to two SIP conference models. Concludes with an…

Recent developments in Internet technologies have enabled new, more flexible forms of telematic simulation and have raised issues that were not considered in the early days of networked learning. Ultimately, these questions revolve around: (1) the learning cost-effectiveness of telematic simulation (quality and quantity of learning as opposed to…

A project undertaken at the University of Minnesota evaluated two microcomputer teletraining systems (audiographic conferencing) to determine the effectiveness of this technology for point-to-point and multipoint distance education. System design requirements included broadcast keystrokes, error checking, master-slave linkages, simultaneous voice…

Asynchronous web-based learning environments are not usually as interactive or adaptive compared to traditional classrooms. The use of synchronous communication tools may be a solution to recreating the link between students and professors. However, synchronous collaborative learning environments are often restricted to a set of communication…

Describes an integrated computer-based conferencing and mail system called ICMS (Integrated Conferencing and Mail System) that was developed to encourage students to participate in class discussions more actively. The menu-driven user interface is explained, and ICMS's role in promoting self-assessment and critical thinking is discussed. (eight…
