The High/Scope Curriculum is a developmentally based approach to early childhood education. The curriculum's "Extensions" newsletter, in which the articles in this collection first appeared, informs curriculum users about new developments relating to the High/Scope "open framework" curriculum. The articles are presented in seven chapters. Chapter 1, "Supporting Active Learning," includes articles on the topics of active learning; social development; adult responsiveness to children; the process of helping children manage themselves; methods for dealing with difficult children; multicultural education; and special needs children. Articles in Chapter 2, "Key Experiences for Child Development," discuss ways to support preschoolers' strengths; communication between children and teachers; children's writing; math learning; experiences with movement; and music. Chapter 3, "The Daily Routine," includes articles on planning by children and schedule planning by teachers. Chapter 4, "Environments for Active Learning," presents articles that examine strategies for active learning; home day care; playgrounds; and children's use of computers. Articles in Chapter 5, "The Team Process: Child Observation, Team Planning, Assessment," consider team teaching; the division of labor; the importance of observation and feedback; assessment; and child-oriented lesson plans. Chapter 6, "Reaching Out to Other Settings and Caregivers," includes articles on transitions; parent involvement; and the appropriateness of kindergarten practices. In Chapter 7, teachers' questions are answered. An appendix lists books and audiovisual materials published by the High/Scope Press. (BC)
