This chapter explores the role of reflection and the development of reflexivity in programs of professional studies in higher education. Serving as empirical basis is a qualitative explorative longitudinal study with students in different master's programs at a University for Professional Studies, considering the students' perspective and their changing understanding and practice of reflection both at the workplace and in their studies. The students' perspective is complemented by an analysis of interviews with teachers in professional master's programs about their teaching strategies supporting students' learning. Linking these two perspectives leads to a developmental model of reflection over the course of studies that allows new ways of interpreting the reflective practitioner in higher education.
