This textbook provides an in-depth introduction to the theoretical perspectives and methods of doing conversation analysis, an approach to the study of talk in interaction which grew out of the work of Garfinkel, Sacks, Schegloff, and Jefferson. This book is unique in that it provides comprehensive instruction in both interaction in ordinary conversations in everyday life as well as talk in institutional settings and a wide range of workplace and business interactions, while teaching both major research findings and how to conduct conversation analytic research. The book is designed to be useful for students of linguistics, sociology, and communication studies, and is written in clear and accessible prose. The Companion Website provides additional resources for instructors, such as questions and data excerpts for tests and in class exercises, audio and video clips for transcription practice, and guides for instructors on a range of topics covered in the course.
