A good EFL teacher is certainly a key factor for effective language teaching but what constitutes a good EFL teacher? Since the portrait of a good EFL teacher is a reflection of students'' and teachers'' beliefs, defining the characteristics of a good EFL teacher falls to both students and teachers. This book presents a comparative look at the Turkish university EFL students'' and instructors'' views on the characteristics of a good EFL teacher. The findings of the study in the book can fill a gap in the Turkish EFL context and can also contribute to the related literature by investigating whether cultural and contextual differences lead to different views of what constitutes a good EFL teacher. Therefore, the findings of the study presented in the book may be beneficial for ELT teachers, language teacher education programs and trainers to improve effective foreign language teaching.
