Abstract
This paper develops early data from a qualitative longitudinal study of the first cohort of five students making the transition from teaching assistant in secondary school to specialist teacher of secondary mathematics. Data from a second cohort of four women and one man starting in 2003 is less complete, but used as appropriate. Bernstein's work on subject classification frames an argument that this student group navigates simultaneously two mathematics discourses: 'hard' university mathematics, and 'everyday mathematics' as experienced by the lower ability school pupils that the students support. This raises questions about the purpose and scope of the students' work in school with respect to their mathematics learning, and vice versa. Macrae, Brown, and Rodd's (2003) study of conventional mathematics undergraduates provides a foil against which to compare approaches to learning mathematics, raising the possibility of a rethink of pre-requisite pre-qualification, and potential relations between university mathematics and work-place learning in secondary schools.
