This paper describes how a Cognitive Task Analysis (CTA) was used to jumpstart the exploration of useful design aids to combat data overload in intelligence analysis. During a simulated analysis task, we observed how professional intelligence analysts were vulnerable to making inaccurate statements when they were under time pressure and working in a topic(More)
Advances in online and computer supported education afford exciting opportunities to revolutionize the classroom, while also presenting a number of new challenges not faced in traditional educational settings. Foremost among these challenges is the problem of accurately and efficiently evaluating learner work as the class size grows, which is directly(More)
Children and young adults are immersed in digital culture, but most are not familiar with the computational thinking behind the latest tools and technologies. There are few opportunities in secondary school curricula for students to learn such practices, but we believe that skills such as computational thinking, creative coding, collaboration, innovation,(More)
Building with a Memory is a subtle responsive intervention that aims to provide cohesion and community awareness through the use of light and color. The installation delivers thought-provoking information by capturing, analyzing and rendering real-time and archived human activity in a workplace setting. The installation senses movement in the space through(More)
In a range of settings, message overload has become a serious problem. People are spending more and more effort managing their inbox to cope with an overload of input messages, with little support for stepping back to put things into perspective (Woods et al., 2002). In the field of intelligence analysis we have seen a fantastic growth in the amount of(More)
We present the research framework for a taxonomy of online educational peer-assessment systems. This framework enables researchers in technology-supported peer assessment to understand the current landscape of technologies supporting student peer review and assessment, specifically, its affordances and constraints. The framework helps identify the major(More)
Emergent order in complex dynamic systems is a concept that is both important to a wide variety of fields of science and difficult to understand and teach. Recent advancements in interactive and tangible interfaces point towards the possibility of new tools which can help with both the analysis and simulation of complex systems, while also making the(More)
