Because standardized tests in science are not given to PreK-3 students in Ohio, this report examined the longitudinal effects of learning from a teacher who had participated in the NURTURES professional development program. Specifically, it looked at the effects on students' mathematics and reading learning in grades 2-5 and science learning in…

The purpose of this study was to examine the role of school background and school process in closing achievement gaps between White and non-White students in science. To answer the research questions, a series of two-level hierarchical linear models (HLM) was performed on the fourth-grade U.S. portion of the 2015 Trends in International…

Background: Socioeconomic characteristics are persistently and systematically related to academic outcomes, despite long-standing efforts to reduce educational inequality. Ireland has a strong policy focus on alleviating educational disadvantage and has seen significant improvements in mathematics and science performance in recent years. This…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

For United States of America (USA) and other developed countries, science achievement gaps begin to emerge in elementary and primary school. Such gaps between USA student groups typically are connected to socio-economic status (SES) and issues such as students still learning the English language. Through an experimental design, this National…

This brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning. Prior research focused on math and reading and found that the pandemic's negative impact steadily accumulated during the 2020-2021 school year, with significant disparities in…

Science achievement gap between fifth, sixth, and eighth grades and boys and girls in low and high performing schools were under investigation in the present study. In accordance with this purpose, three schools were selected to represent high performing schools and two schools were selected to represent low achieving schools for their performance…

Children coming from homes where English is not their first language constitute a significant and increasing proportion of classrooms worldwide. Providing these English-language learners (ELLs) with equitable assessment opportunities is a challenge. We analyze the performance of 485 students, both English-native-speakers (ENSs) and ELLs, across…

Significant racial and ethnic achievement gaps exist between students in the U.S. by elementary school, although the underlying causes for these achievement gaps differ. One factor for racial/ethnic achievement gaps is between-group differences in socioeconomic status (SES), particularly exposure to poverty. Moreover, other factors contributing to…

In the face of rising economic and social inequality, American parents increasingly seek to promote their children's academic achievement through provision of enriching learning opportunities. In this study, we hypothesized that parental investments in both home and out-of-home learning resources may partially explain socioeconomic disparities in…

Propensity score matching was used to compare third-grade test scores in English language arts, mathematics, science, and social studies for children who had and had not participated in Georgia's Pre-K 4 years earlier. After matching, each group included 46,262 children (mean age 8.36 years in third grade). In all subject areas, children who had…

The Houston Independent School District (HISD) offers two primary bilingual programs for Spanish-speaking English learners (ELs). EL students in the district's two main bilingual programs (Transitional and Dual Language) are instructed in both English and Spanish. The relative amount of instruction in each language depends on both program and…

This is the 21st report by the National Center on Educational Outcomes (NCEO) that describes how states publicly report assessment data for students with disabilities in K-12 schools in the United States. The purpose of this report is to examine the extent to which states reported 2017-18 assessment data for students with disabilities "to the…

Students that come from low socioeconomic status (SES) backgrounds are more likely to manifest a science achievement gap when compared to their high SES peers as a result of the myriad of factors that have the potential to influence student performance, including limited access to resources, fewer life experiences, health care concerns, fewer…

Background: In contrast to the extensive research on socioeconomic gaps in reading and math achievement, little attention has been given to socioeconomic disparities in science skills, particularly during the early years of schooling. This emphasis on later years may be problematic because large socioeconomic disparities emerge in the early years,…
