Presentation Slides on "Visualizing the Problem Domain for Spreadsheet Users: A Mental Model Perspective"

In this paper presentation, we introduce a new spreadsheet visualization tool as well as an empirical evaluation of its usability and of its effects on mental models of users. The tool translates traditional spreadsheet formulas into problem domain narratives and highlights referenced cells. The tool was found to be easy to learn and helped the participants to locate more errors in spreadsheets. Furthermore, the tool increased the use of the domain mental model in error descriptions and appeared to improve the mapping between the spreadsheet model and the domain model.
