This book is the first to bring together a collection of recent empirical studies investigating languaging, an important construct first introduced by Swain in 2006 but which has since been deployed in a growing number of L2 studies. The contributing authors include both established and emerging authors from around the globe. They report on studies which elicited languaging in oral or written form, via a range of individual and group tasks, and from a diverse range of student populations. As such these studies extend the scope of extant research, illustrating different and novel approaches to research on languaging. The findings of these studies provide new insights into the language learning opportunities that languaging can afford language learners in different educational and linguistic contexts but also the factors that may impact on these opportunities. As such the book promises to be of relevance and interest to both researchers and language teachers.
