Green outlines a view of academic literacy as social practice, situated within academic communities defined by discipline, institution and broader educational culture. Green identifies the kinds of multi-modal communicative practices that characterise undergraduate academic literacies; highlights the centrality of genre to the production and consumption of academic texts; identifies some features of academic communities and the lines along which they may be differentiated; and specifies the domains of knowledge on which students must draw in order to construct their academic literacies.
