In light of recent debates on ‘public criminology’, this article chooses to focus on teaching as a way of reaching more publics. The various characteristics of a more public and engaged discipline are discussed and applied specifically to the teaching of criminology, including the relative merits and demerits of reorienting teaching in this way. Following on from this discussion, the article outlines some practical ways in which this vision can be realised. Given the many affinities between the Burawoyan concept of public ‘-ologies’ and the scholarship of learning and teaching, an argument is advanced for teaching as one of the first steps towards the practice of a more public criminology.
