In this article, we extend previous work with respect to interrater reliability measure of computer-mediated conferencing and suggest coding categories relevant to problem-based learning. Calculating interrater reliability agreement by... more
Tools for measuring cognitive engagement within online groups have been concerned only with measuring an individual participant's cognitive engagement, without any concern for measuring cognitive engagement within groups. There remains a... more
This paper presents some preliminary findings from a study with the two aims of examining: (i) gender differences in online participation and (ii) methods for obtaining better online debate. A number of research methods were used. The... more
This paper describes work that has the goal of developing an Internet-based learning environment for enabling the remote engagement with art objects. Our aim was to provide a multisensory experience, incorporating information, sound,... more
Successful engineering and evaluation of complex software depends on successfully completing all the stages of the Software Development Life Cycle. There have been many models which illustrate the stages Software Engineers have to go... more
This article empirically validates an existing content analysis scheme and addresses a main concern of researchers about text-based, online transcripts in the form of code-recoding by mapping our scheme to the practical inquiry, cognitive... more
For this study, we used a subsection of the enhanced Problem-Based Learning Grid (ePBL Grid) as a framework for reflection during the adaptation of the Win-Win Spiral model for the development and documentation of software engineering... more
This paper presents a critical appraisal of the Win-Win Spiral model as a possible process model for developing small-scale software from inception to implementation within a semester framework at higher education institutions. It also... more
This paper presents some preliminary findings from a study with the two aims of examining: (i) gender differences in online participation and (ii) methods for obtaining better online debate. A number of research methods were used. The... more
In many domains there is a need to interpret noisy data. In this paper we propose and describe a new design pattern called REPORTER for interpreting and reporting noisy data sets that can be tailored for particular situations. REPORTER... more
Medical staff in the Intensive Care Unit (ICU) need to interpret the high volumes of noisy data generated from the monitors attached to their patients. In this paper we propose a software architecture which processes the ICU monitor data... more
In this article we validate our REPORTER design pattern for filtering, interpreting and reporting noisy datasets with two detailed empirical studies from the authors’ former research endeavors, and we discuss five further recent and... more
Effective management of device-supported patients in the Intensive Care Unit (ICU) is complex, involving the interpretation of large volumes of high frequency data from numerous cardiac and respiratory parameters presented by the ICU... more
Recent research in content analysis has shown the difficulties of achieving acceptable levels of inter-rater reliability with CMC transcripts. This has lead to the development of semi-structured computer conferencing systems, in which... more
Engineering module. The case studies fulfil one of the two core capabilities covered in the module. The marking scheme and two diflerent resolutions to the ethical dilemma posed in one of the scenarios (case studies) reached by particular... more
The main goal of this research is to make learning fun for Nigerian primary school children. We developed an edutainment system called IELS, a unique software prototype within sub-Saharan Africa. Cognitive psychology and mental model... more
