Across the Domains presents research that points to what "really matters" in what is such a complex field of practice. Across the Domains consists of twelve chapters. Both formal and informal mentoring programs are examined, from the perspective of both the mentor and mentee. There are traditional mentor-mentee relationships, e-mentoring, face-to-face mentoring, and blended mentoring studies. Included are mentors from higher education, school-based administrators, teacher leaders, and classroom teachers. Represented is both a national and international perspective. Questions for chapter reflection are included. This book is written for university faculty teaching and interested in furthering the research, development, and dissemination of mentoring programs in Teacher Education, Educational Leadership and Higher Education Programs. In addition, this book would be beneficial for leaders of mentoring initiatives at a State Department of Education; P-12 Central Office Staff Program, Professional Developers, and School-based leaders; and researchers and practitioners who are members of organizations focused on mentoring.
