The 12th Biennial Conference of the Association for Academic Language and Learning was held at the University of Wollongong from 25-27 November, 2015. AALL 2015 UOW, 'Critical Intersections', invited discussion about the critical intersections between a range of discourses and practices that circulate and combine in perplexing and often surprising ways in the broad field of academic language and learning. The conference was organised into six streams that invited consideration of the critical intersections between pairs of concepts, directives or topics. While some of these pairings might not, at first glance, seem conceptually distinct, they are often conceived of or programmed as separate by institutional operations. Presentations addressed one of the following six critical intersections: * Learning & Language; * Digital & Literacy: * Transition & First Year Experience; * HDR Writing & Supervision: * Assessment & Professional Development; and * Numeracy & Literacy. Keynote speakers: Emeritus Professor Ronald Barnett (University of London), Associate Professor Cath Ellis (University of New South Wales) and Dr Kate Bowles (University of Wollongong).
