This report will discuss the development and implementation of a dialogic co-creation model for English language teaching in the Language Resource Centre at the Technical University of Darmstadt, Germany. The focus of this report will be on the impact of content co-creation and its impact on learner and teacher autonomy in English language learning and teaching. This collaborative, dialogic model draws primarily on principles of dialogism and exploratory talk (ET) and exemplifies a novel, learner-centered method for curriculum development and teaching in Higher Education. This learner-centered perspective advances an in-depth understanding of the relationship between language learner and teacher, content and language integrated learning (CLIL), language for specific purposes (LSP), their respective content boundaries, the role of content expert and the inhibition threshold. Three examples of teaching English to university professors and professional staff using this model will be discussed. The author proposes that such a model could be adapted and scaled into larger student groups, too.
