This study investigated the long-term impact of the science writing heuristic (SWH) approach on students' science achievement, focusing on differences between low and high socioeconomic status (SES) groups. Through a longitudinal design, students were divided into control and treatment (at least 1 year of SWH) groups. Polynomial growth mixed…

It is a healthy exercise to debate the merits of using effect-size benchmarks to interpret research findings. However, these debates obscure a more central insight that emerges from empirical distributions of effect-size estimates in the literature: Efforts to improve education often fail to move the needle. I find that 36% of effect sizes from…

We study a decade of achievement gaps for fifth-, eighth-, and 10th-grade students in Norway using administrative population data. Norway is a wealthy and egalitarian country with a homogeneous educational system, yet achievement gaps between students at the 90th and 10th percentiles of parental income and between students whose parents have at…

The use of test scores as a performance measure in high-stakes educational accountability has become increasingly popular since the enactment of the No Child Left Behind Act of 2001 (NCLB), which imposed sanctions such as the threat of losing federal funds unless a state implemented a school accountability system that measures student progress…

Efforts to improve college-completion rates have dominated higher education policy agendas. Performance-based funding (PBF) intends to improve college completion and links state funding for public colleges and universities to performance measures. One critique of PBF policies is that institutions might restrict student access. This study uses a…

This study explores the extent to which "college-ready" students, by high school standards, are assigned to remedial courses in college. We used a unique longitudinal data set that links high school and community college transcript data. Focusing on math, we developed a naming device--"inter-sector math misalignment" (ISMM)--to…

Previous research suggests that gains in positive mental health (often termed flourishing, wellbeing, or competence) is associated with stronger academic achievement. This study examines the relationship between positive mental health at school entry and academic achievement at Grade 3, drawing on a representative sample of Australian children…

Given growing disparities in college enrollment by household income, policymakers and researchers often are interested in understanding whether policies expand access for low-income students. In this brief, we highlight the limitations of a commonly available measure of low-income status--whether students receive a federal Pell grant--and compare…

Prior research suggests that males outperform females, on average, on multiple-choice items compared to their relative performance on constructed-response items. This paper characterizes the extent to which gender achievement gaps on state accountability tests across the United States are associated with those tests' item formats. Using roughly 8…

Papay (2011) noticed that teacher value-added measures (VAMs) from a statistical model using the most common pre/post testing timeframe--current-year spring relative to previous spring (SS)--are essentially unrelated to those same teachers' VAMs when instead using next-fall relative to current-fall (FF). This is concerning since this choice--made…

This paper provides the first population-based evidence on how much standardized test scores vary among public school districts within each state and how segregation explains that variation. Using estimates based on roughly 300 million test score records in math and English Language Arts (ELA) for Grades 3 through 8 from every U.S. public school…

Research on high school math course taking documents the advantages of starting high school at or beyond Algebra 1. Fewer studies examine differentiation into remedial, general, and honors Algebra 1 course types by course rigor. This study examines how course grades and course rigor are associated with math attainment among students with similar…

Early presidents of the American Educational Research Association were leaders in the testing movement. Their intentions were to improve education by means of testing, which included both IQ and achievement tests. Early measurement experts acknowledged in scholarly articles that IQ tests could not measure inherited ability of groups with vastly…

This article provides provide a new, systematic profile of more than 18,000 homeless students in Michigan, utilizing rich administrative data from all test-taking students in Grades 3-9 during three academic years. These data are part of a larger study of school choice and student mobility in that state. Homelessness is a condition found…
