This paper arises out of the transition from a PhD thesis on Heidegger's phenomenology to my attempts to come to terms with ‘becoming a teacher’. The paper will provide a phenomenological interpretation of being a teacher in relation to the question of an ‘authentic’ interpretation of teaching/learning and the possibility of an authentic interpretative praxis. I will argue that being a teacher is a phenomenon of human existence which can be interpreted as a possible way of being with authentic and inauthentic potentialities. This way of being is intrinsically linked to that of learning; of becoming human or becoming the authentic possibilities of being-human. As such, the problem of being a teacher is primarily an ethical question (or a question of ɛτηοσ—dwelling); of who we are as humans and of how being a teacher engages with the in-formation of the becoming of students as authentic human beings. This then leads to the problem of how a phenomenological interpretation of education can be applied or lived; of authenticity in teaching/learning and the possibilities of authentic learning environments (educational dwelling).
