The fourth edition of this text provides an understanding of the nature of curriculum, from a range of perspectives, to enable readers to make their own judgements.  Chapters throughout the book focus upon specific, practical details of the processes involved in developing curricula.  All chapters contain a wealth of examples, up-to-date references, and web sites, which makes it one of the most user-friendly texts available.  This edition has many additional features dealing with the No Child Left Behind legislation, evaluation standards, and large scale curriculum implementation examples.
