The purpose of this quantitative ex post facto study was to determine if, and to what extent, differences existed in pre-and-post math scores following the VMath intervention for Title I 6th, 7th, and 8th graders in the Southwestern United States. Three research questions guided this study: (1) is there a statistically significant difference in…

A growing number of studies have shown the benefits of K-12 integrated science and engineering education. With this study, we add to the literature by documenting the relationship between STEM learning and engagement, and the demographic characteristics that impact achievement in STEM. This longitudinal study followed a diverse group of 245 middle…

The current study evaluates effects of teaching factors and extended day programs regarding both average achievement and socioeconomic achievement gaps. Analyses are based on data from the National Educational Panel Study in Germany. The sample comprises 1523 students in 120 classes in 71 secondary schools. The investigation period covers fifth…

Strong evidence indicates that student expectations of success in mathematics decline in middle school. The goal of the present study was to examine whether the expectations of teachers and the quality of the student-teacher relationship play a role in these declines. A total of 201 (86 boys, 115 girls) Latino/a students (M = 11.0 years) and their…

The purpose of this study was to analyze the impact of the reading program, System 44, on students with learning disabilities in grades six and seven at a small rural middle school. The middle school implemented the reading program during the 2018-2019 school year to assist students reading below grade level to "catch up" or close the…

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…

This research brief examines the continuing impact of the COVID-19 pandemic on student achievement and progress toward academic recovery. Using data from 6.7 million U.S. public school students currently in grades 3-8, the study examined academic gains in the 2022-23 school year relative to pre-pandemic years. It also tracked the gap in…

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…

This study examined data from the Institute of Education Sciences' evaluation of school-based mentoring (SBM) programs to establish a causal relationship between SBM and reduction of the academic achievement gap between African American and White middle school students. Participation in SBM improved the academic performance of all students. The…

This is the technical index for the research brief "Education's Long COVID: 2022-23 Achievement Data Reveal Stalled Progress toward Pandemic Recovery." Using data from 6.7 million U.S. public school students currently in grades 3-8, the study examined academic gains in the 2022-23 school year relative to pre-pandemic years. It also…

Growing evidence suggests that contrary to popular belief, schools mostly do not generate achievement gaps in cognitive skills but, rather, reflect the inequalities that already exist. In the case of socioeconomic status, exposure to school often reduces gaps. Surprisingly little is known, however, about whether this pattern extends to gender gaps…

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…

Over the past 30 years, numerous policies have focused on closing the achievement gap in the United States. Despite this emphasis on mastery and proficiency, students continue to perform below expectations. We use standardized math test performance to explore whether schools have been able to eliminate the achievement gap across middle-level…

This paper discusses a longitudinal study of North Carolina middle level student proficiency levels on standardized assessments since the shift to the Common Core curriculum. Student poverty and its impact on student achievement the focus of this paper, and this study analyzes long-term proficiency trends and while delving into inequity…

Ethnoracial inequality in educational achievement and attainment is a long-standing feature of the American education system. For example, national reading assessments show that White fourth graders scored nearly a standard deviation higher than Black or Hispanic students on average in 2015 (NCES, 2015). The measurement and analysis of differences…
