The importance of academic literacy acquisition through enculturation in higher education is self-evident. Important within the processes of enculturation is how interactants are positioned. This study examines how interactants within the writing classroom of a higher education institution in Ghana are positioned through dialogue. Data for this study are recordings of lectures of a mandatory undergraduate programme. The study indicates that though there are attempts to position the student as an active and equal participant within the writing classroom, the instructor still emerges as dominant participant. It also establishes that the pedagogical practices of the classroom adopt strategies such as peer deliberations, and epistemic discovery to help foster personal agency development in the student. It concludes that the academic literacies model has not informed what goes on in the literacies classroom of the institution. The study recommends that the enculturation processes will have to adopt a more critical approach.
