The paper proposes an approach to comparative usability evaluation that incorporates important relevant criteria identified in previous work. It applies the proposed approach to a case study of a comparative evaluation of an academic website employing four widely-used usability evaluation methods (UEMs): heuristic evaluation, cognitive walkthroughs, think-aloud protocol and co-discovery learning.

To explore the issue of culture in persuasive technology, we identified strategies distinguishing individualist or collectivist audiences, and developed two versions of a prototype game. In this paper we report on a qualitative study of this game. The game concerned smoking cessation, and was set in a New Zealand context, where one version was designed for individualist New Zealand Europeans, a...

Motivated by both classroom needs and learning science questions, we developed two computer-based systems to help students learn the English article system (a, an, the, null). The first system, a menu-based task, mimics cloze activities found in many ESL textbooks. The second, a controlled-editing task, gives students practice with both detecting errors and producing the correct response. Resul...

The paper introduces a new research strategy for the investigation of human translation behavior. While conventional cognitive research methods make use of think aloud protocols (TAP), we introduce and investigate UserActivity Data (UAD). UAD consists of the translator’s recorded keystroke and eye-movement behavior, which makes it possible to replay a translation session and to register the sub...

Pervasive and ubiquitous computing has come a long way in recent years, and our technologies and experimental prototypes are slowly moving out of the lab and into people’s everyday lives. In this talk I will provide an overview of such research conducted by my team over the past years, and outline the main challenges that we face in the future, particularly in terms of making our technology acc...

COLLECT-UML is an intelligent tutoring system that teaches Object-Oriented design using Unified Modelling Language (UML). UML is one of the most popular techniques used in the design and development of Object-Oriented systems nowadays. The Constraint-Based Modelling (CBM) has been used successfully in several systems and they have proved to be extremely effective in evaluations performed in rea...

W investigate the epistemology of trust in social networks. We posit trust as a special epistemic state that depends on actors’ beliefs about each others’ beliefs as well as about states of the world. It offers new ideas and tools for representing the core elements of trust both within dyads and larger groups and presents an approach that makes trust measurable in a noncircular and predictive, ...

The tadpole larva of a sea squirt is only the second animal to have its entire nervous system mapped out, and the results confirm that there is still much to learn from the smallest brains.

Asked to reflect on my own research and career after being selected for the great honor of the Women in Cell Biology Mid-Career Award for Excellence in Research, I found myself contemplating not only how I approach my own science but also how this approach contributes to the larger scientific enterprise. Here I discuss my motivations and their impact on how I conduct my research as one example ...
