This sixth edition of this book continues with its original perspective on instructional leadership. As in earlier editions, it brings perspectives of change, classroom practice, instructional leadership, adult development, staff development, evaluation, and political and social theory into the everyday life of schools. It is designed as a textbook for students learning to become administrators and as a guide for practicing administrators. New to this edition are such topics as school improvement, constructivist teaching, professional development, Chaos Theory, and state-mandated standards. It is organized into six parts: (1) "Introduction" includes background material; (2) "Knowledge" looks at effective-schools research, adult and teacher development, and educational philosophy; (3) "Interpersonal Skills" discuses various types and styles of supervisory behavior; (4) "Technical Skills" addresses assessing, planning, observing, research, and evaluation skills; (5) "Tasks of Supervision" discusses group, professional, teacher, and curriculum development; and (6) "Functions of Supervisor" addresses educational change and reform. Following each chapter are a summary, sets of exercises for students and practitioners, a list of references, and a list of suggested readings. (Contains three appendices, a name index, and a subject index.) (WFA)
