English Language Teaching has been in a continuous development as the language itself. The political, sociological and technological changes in the global scale impact the field of language teaching as well. As a result of these changes, the roles of policy makers, teacher educators, prospective teachers and in-service language teachers are changing in a similar sense. The aim of this book series is to keep all these parties up to date regarding both content and pedagogical knowledge and inform them about the new trends in the field of English language teaching. To meet these purposes, the books included in the series are designed to help readers to better internalize the content by presenting academic and practical tasks and activities. We would like to thank to the editors and authors of each book for their valuable time, knowledge and attention devoted to this series.
