The background to this paper is based on the ongoing need to place more attention on the importance of teaching. The aim in so doing is to lead to a better valuing of teaching which, in the case of this paper, is through an exploration of the notion of teaching as a discipline. There are differing views about that which constitutes a discipline and considering teaching as a discipline is a provocative way of focusing on the complex nature of that work in order to make clear that teaching is much more than "simply doing." Through a review of the diversity of views of disciplines--and education as a discipline--as described in the literature the paper considers the consequences of conceptualizing teaching as a discipline which are significant not only for teaching itself but also for teacher education. The paper concludes that if teaching is to be considered a discipline, then teacher education itself needs to be understood and practiced as a much more scholarly activity. This paper works through some of the arguments that arise as a consequence of thinking about teaching as a discipline and challenges the teaching and teacher education communities to conceptualize their work in ways that will engender a great sense of valuing of that work.
