This report presents results from four 1999 Urban Systemic Initiative (USI) school district surveys. The Survey of Enacted Curriculum is the study component of a grant from the National Science Foundation to examine how reform works in USI districts. The study explores the impact of USI programs on student achievement and the learning infrastructure in urban school districts and will develop an inferential causal model linking USI drivers and other key elements. This survey analyzes urban school mathematics and science practices, focusing on enacted curriculum contents and teaching practices. It provides a means of validating reform changes in the four sites by analyzing responses from intervention and control group teachers. In each site, 80 teachers were selected from 20 elementary and middle schools. The initial report on enacted curriculum in USI sites demonstrates that: the survey approach tried at the four USI sites can be used to analyze curriculum and teaching in classrooms; the analysis can be used across different classes, schools, and districts; and a purposeful sample of schools and teachers can be used to compare curriculum and instruction in schools that have high implementation of systemic reform with USI schools that have less implementation. Appendixes include the USI evaluative study abstract and year one progress summary, a brief description of four USI school districts, class descriptions, and content maps. (SM)
