This text synthesizes instructional supervision, adult development, teacher education and mentoring, and ongoing professional development. Also forges links between preservice teacher education, mentoring, and school- based supervision. Practical examples and case studies are drawn from extensive work with urban, suburban, and rural school systems, as well as a number of state, national, and international public school/university consortia. First book in the field to focus on mentoring. Provides a unique framework for action/reflection, grounded in theory and 20 years of research to guide supervision and professional growth programs (Ch. 4). Distinct chapters discuss guided reflection (Ch. 13) and ethics relative to supervision (Ch. 15). Biographies highlight leaders in the field.
