This book sheds new light on classroom indiscipline by listening to the voices of both the teachers and the young learners of English as a Foreign Language (EFL). By focusing on data from multiple sources, chapters in this volume offer a thorough description of undisciplined learner acts, a framework for categorizing indiscipline types, an exploration of perceived causality beyond the observable behavior, and of management strategies and their evaluation by teachers and children. The author offers practical guidance on creating a disciplined EFL learning classroom atmosphere through multilateral educational aims and processes. This book is a point of reference for academics, researchers, university students, educators and teacher trainers who wish to enhance the design and implementation of reliable multi-lens qualitative case studies on the subject. With its elucidating and transformative power, it inspires further innovative research and practical initiatives for the understanding and successful management of child indiscipline in diverse EFL learning contexts.
