This paper focuses on physical education for students in preschool (3 to 5 years) and primary grades K-2 (5 to 7 years). It describes developmentally appropriate practices as a set of indicators for high quality play and motor skills programs for all children, including children with special needs. The paper also describes and recommends an outcome driven decision making model to integrate the identified quality program indicators for making instructional and curricular decisions to serve all children. The paper notes changing demographics that bring new faces to schools and challenge the shape of school programs. It describes "best practices" derived and adapted from developmentally appropriate practices in general education, early childhood education, learning and movement principles, and early childhood special education. Specific attention is given to how these predictors of quality programs become integrated into a service delivery system tailored to meet the needs of each child, through teacher and instructional adaptations and improvements. Selection of relevant preschool play and motor skills teaching materials is also addressed. (Contains 26 references). (JDD)
