Based on leading-edge research and current practices from a wide range of well-respected researchers, this transformative book is a must-read if we want to move from the ITA problem to a 21st century multidisciplinary perspective where ITAs are truly valued. Having read the book, Im encouraging everyone I know involved in ITA preparation to read and discuss it. * Colleen Meyers, University of Minnesota, USA * I value this book for shifting the discourse on the 'ITA problem' to 'ITA resource'. The authors insightfully draw from transdisciplinary research approaches to expand the orientation from purported grammatical deviations to social interactions, identity negotiations, and cultural resources that demonstrate the creativity and complexity of ITAs. This book is bound to change the conversation on ITAs for years to come. * Suresh Canagarajah, Pennsylvania State University, USA *
