Abstract
The research presented in this paper confronts head on the difficult question of
teacher change. It was catried out with preservice teachers in a mathematics
methods course in the second year of their teacher education program.
Collected data reveal how students' prior experiences of institutionalised
mathematics reveal patterns of subjectification which actively undermine the
future implementation of more investigatory methods of teaching. I use the
poststructuralist concepts of knowledge, positioning and subjectivity:
initially as analytic tools to expose the coercive operation of the mathematics
discourse; and collectively, as a conceptual base from which to think about
possibilities for change.
