The main aim of this article is to explore the ways in which teacher educators can improve levels of reflection in postgraduate student teachers. The author argues that postgraduate student teachers are able to reflect on their practice in schools, and that the insights gained are useful in clarifying their own beliefs about teaching and learning. The outcome of such reflection at an early stage of their career may have implications for their ability to engage with the development opportunities made available to them as they move through their teaching careers. Using a qualitative approach, data from the learning journals and reflective writing assignments of student teachers, and a focus group interview, are examined in order to evaluate students' ability to engage in reflective writing at various stages over a 1 year course. The support given to students over the course of the year is examined with a view to evaluating its impact on students' abilities to reflect on their practice and their own learning. A number of recommendations are made for possible improvements to supporting student teachers in this important area of work.
