*The Ninth Edition of Curriculum Improvement is comprehensive, unique, practical, and thought-provoking. Despite the problems it cites, the book offers a message of hope -- that schools can help to solve society's problems by impressing upon children and youth that they can achieve and succeed if they act in doing what they know to be right and productive. Since its initial publication, this text has been enormously popular. It relies not only on the distinguished research of theorists such as Havighurst, Piaget, and Tyler for hard data in curriculum foundations, but also on curriculum practice in schools, in which the author has been a major participant as a curriculum coordinator and specialist in various fields. The author has continued in this tradition of integrating theory into practice by concentrating each revised edition on new developments in curriculum inquiry and practice. Many students have noted that in the revisions, the author reports real experiences in which he has often had a part. "To those of us in practice," some have said, "he seems like one of us." The situations and activities within the chapters reflect these comments.
