Abstract In this paper, we put Basil Bernstein’s theory of pedagogic discourse to work
together with additional theoretical resources to interrogate knowledge and practice in
mathematics teacher education. We illustrate this methodology through analysis of an
instance of mathematics teacher education pedagogic practice. While the methodology itself
is our focus, the particular example provides a compelling story at the heart of which is the
problem of integration of knowledge(s) within a pedagogic practice. Here, a constructivist
pedagogy is at work, but differentially with respect to teaching/learning mathematics and
teaching/learning mathematics teaching. The example illuminates mathematics and teaching,
and their co-constitution in a particular pedagogic context.
