The purpose of this paper is to explore students' discourse when working in small groups on mathematical problems using GeoGebra. Specifically, the interest lies in to what extent the discourses are internally persuasive and to what extent they are alien to the students themselves. The data analysed are drawn from an upper-secondary class of students with histories of low attainment, focusing on functions and the Cartesian connection between algebra and geometry. Discourses of visual appearance were more present than academic mathematical discourse, and discourses of school as compliance counteracted students' appropriation of mathematical discourses into their own internally persuasive discourses.
