This article examines how male undergraduate students from linguistic minorities and non traditional university backgrounds perform gender (Butler 1990), viewed from the perspective of identity, on an academic writing programme and discusses what this tells us about the significance of gender for the teaching of academic writing in the contemporary academy. I focus on how gender is performed in talk about academic discourse and reveal the attraction of laddish identities for the men in the study. In so doing, I aim to deepen understanding in English for Academic Purposes of the importance of the social world for the social relations of the writing classroom and contribute to research that has considered identity in relation to the written outputs of students and scholars outside classroom settings (Hyland 2012;Ivanič 1998;Lillis 2001). To gain a more nuanced understanding of gender, an intersectional approach (Block and Corona 2016) is adopted, in which gender is viewed in intersection with social class. I argue that the gender-class nexus is of key significance for the teaching of academic writing in that it reveals how the social world orients language learners to language learning and sheds light on how students, as agentive beings, negotiate their positioning in discourses of deficit. I demonstrate how understanding of these issues can be developed through fine grained analysis of spoken interaction in the classroom and contend that language-as-resource approaches to linguistic diversity offer a productive way forward for EAP and, more widely, for teaching in contexts of linguistic diversity in higher education.
