The link between reading and mathematics achievement is well known, and an important question is whether readability factors in mathematics problems are differentially impacting student groups. Using 20 years of data from the National Assessment of Educational Progress and the Trends in International Mathematics and Science Study, we examine how…

The sizable gender gap in college enrolment, especially among African Americans, constitutes a puzzling empirical regularity that may have serious consequences on marriage markets, male labor force participation and the diversity of college campuses. For instance, only 35.7 percent of all African American undergraduate students were men in 2004.…

The School Composition and the Black-White Achievement Gap study was undertaken by the National Center for Education Statistics to present both descriptive and associative information on the relationships among the percentage of students in a school who were Black (referred to as "Black student density" or "density"), the…

The National Assessment of Educational Progress--commonly called "The Nation's Report Card"--tells a dismal story: Only 2% of high school seniors in 2010 could answer a simple question about the U.S. Supreme Court's landmark "Brown v. Board of Education" decision. And it's no surprise. Across the country, state educational…

Two versions of a general method for approximating standard error of regression effect estimates within an IRT-based latent regression model are compared. The general method is based on Binder's (1983) approach, accounting for complex samples and finite populations by Taylor series linearization. In contrast, the current National Assessment of…

Data from 10,000 17-year-old respondents to the National Assessment of Educational Progress (NAEP) 1975-76 Special Mathematics Probe (Basic Mathematics Assessment) were analyzed. The primary purpose was to identify respondents' background characteristics associated with basic mathematics achievement. The achievement items and 241 background…

More than a dozen statistical models have been developed for the purpose of cognitive diagnosis. These models are supposed to extract a much finer level of information from item responses than traditional unidimensional item response models. In this paper, a general diagnostic model (GDM) was used to analyze a set of simulated sparse data and real…

National math assessment data from 3,112 eighth-grade students in 123 schools were used to determine whether location (rural versus nonrural) affects student achievement when related student and school-level factors are taken into account. Findings indicate that rural schools outperformed nonrural schools in math achievement and that the…

Students with disabilities represent a relatively small but important group of students in U.S. high schools. The education of these students is heavily influenced by federal and state law as well as by longstanding beliefs about the purpose of education and the extreme heterogeneity of the population. Until recently, general educational policies…
