In a digital environment, the visual output and its distinctive qualities can lead to interpretation and response of a particular nature. In this paper the notion of visual perturbance is explored, and situated within the data obtained, when ten-year-old children engaged in number investigations in a spreadsheet environment.application/pdfenThis article has been published in Proceedings of the 30th Annual Conference of the Mathematics Education Research Group of Australasia.
