Taking a dialogic approach, this edited book engages in analysis and description of dialogic discourse in a number of different educational contexts, from early childhood to tertiary, with an international team of contributors from Australia, Finland, New Zealand and the United Kingdom. The chapters focus mostly on dialogic face-to-face discourse, with some examples of online interactions, and feature insights from educational linguistics, particularly the work of Michael Halliday. While the contributors come from a range of theoretical backgrounds, they all share an interest in language in use and engage in close analysis of transcripts of naturally-occurring interaction. Taking inspiration from Alexander and other theorists, they employ a fine-grained and analytic approach to the exploration of their data. The authors make use of the linguistic tools and models of language in society, in order to examine the turn-by-turn unfolding of the interaction. The authors relate their insights from disparate forms of linguistic analysis to elements of Alexander’s (2020) dialogic framework, situating the discourse in its contexts and discussing the pedagogical implications of the linguistic choices at play.In presenting this work from a range of situations and perspectives, the authors strive to demonstrate how dialogic discourse plays out in educational contexts across the world. The book aims to foster further research in this direction and to inspire educators to explore dialogic discourse for themselves. It will be of interest to a wide audience, including literacy researchers, linguists, teachers and teacher educators, as well as graduate students.
