Developing Visualisations For Spreadsheet Formulae: Towards Increasing the Accessibility of Science, Technology, Engineering and Maths Subjects

Spreadsheets are widely used within Science, technology, engineering and maths education. Despite their widespread use, end-user spreadsheet errors are still extremely common and have been shown to have an adverse effect on learning. The textual representation of formulas can be particularly complex and error-prone, exacerbating barriers to dyslexic users. Our work focuses on the design and development of a visual language to graphically represent spreadsheet formulae, with the objective of making them easier to understand than their default textual form. This work contributes to a body of human factors research focused upon spreadsheets.
