Educational Testing Service
The science achievement of U.S. students has been flat for a decade; in fact, in a recent international assessment, U.S. students ranked lower, on average, than their peers in 16 of 30 developed nations. The National Assessment of Educational Progress (NAEP), in addition to serving as the nation's report card, collects information from students, teachers, and schools on instructional practices, teacher characteristics, and school factors, allowing the authors to peer into U.S. schools and view students and teachers as they interact in the context of schools and classrooms. This report takes advantage of these data and provides a view of eighth-grade science classrooms in 2005, using statistical models particularly suited to this type of data--hierarchical linear models (HLMs). The authors' intent is to identify teacher characteristics and instructional strategies that are associated with student science achievement. After briefly describing the state of science achievement, teacher characteristics, and instructional strategies across U.S. eighth-grade classrooms, the report presents the results of a three-phase analysis that is designed to illuminate the statistical relationships among these variables. Appendices include: (1) Data for HLM; (2) HLM Methodology; and (3) Standard Errors and Significance Tests for Figures 3 to 13. (Contains 24 footnotes, 11 tables, and 13 figures.)
