This volume contributes to ongoing discussions of ethics in Applied Linguistics scholarship by focusing in depth on several different sub-areas within the field. The book is comprised of four sections: methodological approaches to research; specific participant populations and contexts of research; (language) pedagogy and policy; and personal and interactive aspects of research and scholarship. Moving beyond discussions of how ethics is conceptualized or defined, the chapters in this volume explore ethics-in-practice by examining context-specific ethical challenges and offering guidance for current and future Applied Linguistics scholars. This volume responds to the need to provide context-specific research ethics training for graduate students and novice researchers interested in a variety of contexts and methodological approaches. After engaging with this volume, new and experienced applied linguists alike will gain familiarity with specific ethical challenges and practices within particular sub-disciplines relevant to their work and across the field more broadly.
