Abstract

Visualisation is often presented as a means of simplifying information and helping people understand complex data. In this paper we describe a project designing interactive visualisations to support learner competencies in the broad area of numeracy. The work builds upon: (i) the observation that while spreadsheets are traditional ICT tools, their familiarity means that they are used for exploratory mathematical modelling; (ii) a research theme examining the human factors that influence the ease with which formal notations can be understood and applied appropriately. Our paper describes the iterative design and evaluation of a tool to visualise spreadsheets, with the aim of supporting mid-teen learners based on the premise that spreadsheets serve as a gateway tool for supporting learner experimentation and confidence within numerate subjects. This iterative process is informed by background research into notational design, graphic design as well as learner and tutor feedback.
