We compared discussion posts from a data science ethics MOOC that was hosted on two platforms. We characterized one platform as "open" because learners can respond to discussion prompts while viewing and responding to others. We characterized the other platform as "locked" because learners must respond to a discussion prompt…

Information Communication Technology (ICT) is ubiquitous in the 21st century, hence both educators and learners need to integrate relevant ICT resources in their teaching and learning practices, to meet stakeholder's expectations and keep abreast with the race of technological advancement. The current research focuses on the analysis of ICT…

Online discussion plays an increasingly significant role in asynchronous online learning environments. While previous attempts have been made to develop learning analytics dashboards to facilitate such discussions, most of these dashboards have been designed without reference to data or visualization techniques that have been proven to make online…

The majority of the world is multilingual, but inequitably multilingual, and much of the world is also technologized, but inequitably so. Thus, researchers in the fields of computer-assisted language learning (CALL) and second language acquisition (SLA) would profit from considering multilingualism and social justice when envisioning new CALL-SLA…

The recent trend toward patients participating in their own healthcare has opened up numerous opportunities for computing research. This dissertation focuses on how technology can foster this participation, through user interfaces to effectively communicate personal health status and care progress to hospital patients. I first characterize the…

Purpose: The purpose of this paper is to present a user interface for web lectures for engaging with other users while working with video based learning content. The application allows its users to ask questions about the content and to get answers from those users that currently online are more familiar with it. The filtering is based on the…

To investigate the most efficient way to represent text in reading Chinese on computer displays, three typographic variables, character size (41[feet] arc/24 pixels and 60[feet] arc/32 pixels), character spacing (1/4 and 1/8 character width) and font type (Kai and Ming), were manipulated. Results showed that the reading speed for Chinese…

In this study, a Surface Computer Supported Cooperative Work paradigm is proposed. Recently, multitouch technology has become widely available for human-computer interaction. We found it has great potential to facilitate more awareness of human-to-human interaction than personal computers (PCs) in colocated collaborative work. However, other…

Conflicts occur when learners interact with pedagogical agents and virtual characters. Such conflicts--arising from technological limitations, psychosocial perceptions, and pedagogical inadequacies--hinder communication and interaction between virtual characters and learners, and impede successful engagement with learning tasks and experiences. To…

This paper reports on an aspect of the EC funded Argunaut project which researched and developed awareness tools for moderators of online dialogues. In this study we report on an investigation into the nature of creative thinking in online dialogues and whether or not this creative thinking can be coded for and recognized automatically such that…

Purpose: At many universities, web lectures have become an integral part of the e-learning portfolio over the last few years. While many aspects of the technology involved, like automatic recording techniques or innovative interfaces for replay, have evolved at a rapid pace, web lecturing has remained independent of other important developments…

This paper examines the effective deployment of conversational agents in virtual worlds from the perspective of researchers/practitioners in cognitive psychology, computing science, learning technologies and engineering. From a cognitive perspective, the major challenge lies in the coordination and management of the various channels of information…

This study focuses on how to support students who have to work together in small groups, and who do not know each other, in performing grounding discussion. It compares two different implementations of a script, one using a structured interface, one using a textual instruction, on students' discussion behavior. The experiment involved two…

Computer-based communication has tremendous potential to support older adults. But if people are to use such systems autonomously, it is necessary to move beyond current interfaces and systems and develop devices that fit into the environment of the user. Using a Grounded Theory approach, three focus groups were held and, subsequently, 9 older…

This paper describes how the Teaching and Learning Research Programme (TLRP) has implemented and applied DSpace as a digital repository for project and programme outputs, including published articles, conference papers, research reports, briefings and press releases. The DSpace repository has become a major element in the user engagement strategy…
