Abstract

Abstract: The purpose of this study is to examine the characteristics of US schools associated with two measures of scientific literacy (content knowledge and "procedural and epistemic" knowledge) using the 2015 Programme for International Student Assessment (PISA) data. Because outcomes are nested within students, and students within schools, a multivariate three‐level modeling method was employed. About 21% of the total variance in science performance lies between schools, indicating that school characteristics are important in predicting scientific literacy. The results revealed clearly significant and positive relationships of the student‐level variables of grade, enjoyment, motivation, and economic/social/cultural status (ESCS) with both measures of science literacy, after controlling for school factors. A significant gender difference is seen in science content knowledge in favor of males. At the school level, the results from the full model suggest that school ESCS, climate, and school type are significant predictors of all students' performance. Surprisingly, school size, teaching experience, professional development (PD) participation, and science‐specific resources are not found to contribute significantly to achievement. Considerable variability is also evident among schools on student performance in both science knowledge domains as a result of school variables. For both low‐ and mid–high‐achieving students, the most significant school factor is school mean ESCS. PD participation and school climate are significantly associated with student performance only for the average and high‐performing groups. This paper can inform policymakers, researchers, and educators on how US schools can be supported to improve science learning.
