Book excerpt: This book focuses on the nexus of language, disciplinary content and knowledge communication against the background of the economic, cultural and ideological forces of Higher Education’s current push for internationalisation. It suggests the need for a greater synergy between language and content experts and argues that change needs to be implemented through policy rather than on an ad-hoc basis by individual teachers. It is a call to action for English for Academic Purposes practitioners to find a way out of the silo of their own centres and work to assert influence over the wider context in which they work. The book begins and ends in the practice of teaching, with a focus throughout on understanding the barriers and enablers to that practice within a particular context.
