The constitution of the nature of mathematics in the lecturing practices of three university mathematics teachers

subject

description

International audience; The study reported in this paper investigates how notions of the nature of mathematical knowledge and mathematical objects are articulated in the discursive practices of three university mathematics teachers at a Swedish university. The data consists of video recorded lectures, and the analyses were informed by classifications presented by Lerman (1990) and Davis and Hersh (1981). The results indicate that different epistemological and ontological positions are indeed constituted through the discourse. Although the discourse is generally highly objectified, the ways in which mathematical objects are introduced differ. Mostly the discourse was within an ab-solutist paradigm, but there were also examples of how the socio-historical nature of mathematical knowledge is emphasized.
