  • Heuristic evaluation : Comparing ways of finding and reporting usability problems
  • 2007

  • Journal article (peer-reviewed)abstract
    • Research on heuristic evaluation in recent years has focused on improving its effectiveness and efficiency with respect to user testing. The aim of this paper is to refine a research agenda for comparing and contrasting evaluation methods. To reach this goal, a framework is presented to evaluate the effectiveness of different types of support for structured usability problem reporting. This paper reports on an empirical study of this framework that compares two sets of heuristics, Nielsen's heuristics and the cognitive principles of Gerhardt-Powals, and. two media of reporting a usability problem, i.e. either using a web tool or paper. The study found that there were no significant differences between any of the four groups in effectiveness, efficiency and inter-evaluator reliability. A more significant contribution of this research is that the framework used for the experiments proved successful and should be reusable by other researchers because of its thorough structure.

  • Social Software for Professional Learning : Examples and Research Issues
  • 2006
  • In: Proceedings - Sixth International Conference on Advanced Learning Technologies, ICALT 2006. - 0769526322 ; , s. 912-915
  • Conference paper (peer-reviewed)abstract
    • Social software is used widely in organizational knowledge management and professional learning. The PROLEARN network of excellence appreciates the trend of lowering the barriers between knowledge and learning management strategies for organizations and individuals. But, companies should not underestimate the needs for systematic support based on sound theories and technologies. We illustrate the requirements by examples and research issues for collaborative adaptive learning platforms for workplace learning in organizations
