Reconceptualizing intervention and change in conversation analytic perspectives, this volume not only illustrates actual, rather than imagined, ways of conducting CA-informed interventions in a variety of teacher-training contexts around the globe but also documents the impact of such interventions on teacher development.

 ?The contributors to this volume have intentionally moved CA beyond a descriptive methodology to recognizing how CA-influenced decisions and procedures can, and do, result in productive changes in teachers? interactional and instructional pedagogies.  A gift to the field of Language Teacher Education, this volume offers rich data-driven evidence of the material impact of engagement with CA on the professional development of language teachers.? (Karen E. Johnson, The Pennsylvania State University, USA)

 ?The contributors illustrate how CA-based frameworks can help both pre-service and in-service language teachers sharpen their professional vision and enhance their pedagogical skills, making a compelling case for integrating CA into language teacher education while offering concrete guidance for developing teachers' interactional awareness and competence. This groundbreaking volume will be a key reading in both Applied Linguistics and TESOL programmes.? (Steve Mann, University of Warwick, UK)

 ?Conversation Analysis (CA) should be an integral part of teacher-training programs. This plea is convincingly made in this new volume. After many years of CA studies of classroom interaction, it was only a matter of time before CA should enter teacher-training programs. The reports from the US, Sweden, Germany, Türkiye and Japan in this volume show that that time is now.? (Tom Koole, University of Groningen, The Netherlands)
