This book draws on a review of literature on the motivational research from multiple countries with special emphasis on Turkey. It provides information to further our understanding of why people decide to become teachers, and after they become teachers why they stay in the profession or leave it. Studies about teacher motivation, and demotivation are shared to bring to light the scope and nature of this issue. It offers recommendations for administrators and policy makers about the preparation of teachers for the profession, about the in-service trainings, and the coping strategies needed for teacher demotivation, burnout, and stress in the profession. It is strongly recommended as a resource to be used in educational sciences, educational psychology, and comparative education related classes.
