This paper examines the context of teacher education in which certain students work as teachers whilst at the same time they study in a teacher education programme. The two phenomena that are discussed are the integration of theory and practice, and learning while working. These are located in the wider framework of teachers' pedagogical thinking, and research-based teacher education. The paper reports on students' experiences of the success of integrating theoretical studies in their work as teachers and the related issue of how a student's everyday grasp of classroom practice has been taken into account in their studies. The paper also raises the issue of the university-school relationship through students' estimations of the impact that their participation in teacher education has brought to the school in which they work and other key aspects of the university-school relationship.
