Recent research reveals consistent lags in American students' science achievement scores. Not only are the scores lower in the United States compared to other developed nations, but even within the United States, too many students are well below science proficiency scores for their grade levels. The current research addresses this problem by…

This study investigates the relationship between school-level accountability practices and science achievement of 15-year-olds, across four counties: Australia, Korea, Portugal, and the United States. We used PISA 2006 data, since 2006 is the only administration that has focused on science. School-level accountability practices are here defined as…

Although young children display various types of interests, little is known regarding the potential impact of these interests on subsequent learning and development. Of particular importance is the question of whether or not children's early interests are instrumental in their later academic achievement. The current study fills this gap in the…

Research on science achievement disparities by gender and race/ethnicity often neglects the beginning of the pipeline in the early grades. We address this limitation using nationally representative data following students from Grades 3 to 8. We find that the Black-White science test score gap (-1.07 SD in Grade 3) remains stable over these years,…

Little research currently examines language instruction educational programs (LIEPs) in states with a more recent growth of the Latino English learner population. To meet this need, the authors examined the content each of the state LIEPs, focusing chiefly on the extent to which the types of language support, as well as the stipulations associated…

The relationship between student's home environment and achievement in science was examined using data from the 1985-86 National Assessment of Educational Progress, Science Assessment, for a nationally representative sample of American school age children in grades 7 and 11. Science achievement and background data were also collected for grade 3.…
