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…

To answer questions about how students' proficiencies are changing over time, educational researchers are looking for data sources that span many years. Clearly, for answering questions about student growth, a longitudinal study--in which a single sample is followed over many years--is preferable to repeated cross-sectional samples--in which a…

The article argues that science assessment should change from an item-driven to a construct-driven practice and pay more attention to disciplinary scientific reasoning. It investigates assessment scales developed from a novel theoretical rationale, describing scientific reasoning as three fundamental practices (hypothesizing, experimenting, and…

This report shows the impact of various school funding measures on student outcomes measured by NAEP, ACT, and SAT scores, the four-year cohort graduation rate, and percent of the population ages 18-24 with at least a high school diploma. State-level data for the United States from 2005 through 2014 as available is utilized to establish the nature…

Some form of a short interrupted time series (ITS) is often used to evaluate state and national programs. An ITS design with a single treatment group assumes that the pretest functional form can be validly estimated and extrapolated into the postintervention period where it provides a valid counterfactual. This assumption is problematic. Ambiguous…

The 2011 NAEP-TIMSS linking study conducted by the National Center for Education Statistics (NCES) was designed to predict Trends in International Mathematics and Science Study (TIMSS) scores for the U.S. states that participated in 2011 National Assessment of Educational Progress (NAEP) mathematics and science assessment of eighth-grade students.…

At present, although the percentages of students with disabilities (SDs) and/or students who are English language learners (ELL) excluded from a NAEP administration are reported, no statistical adjustment is made for these excluded students in the calculation of NAEP results. However, the exclusion rates for both SD and ELL students vary…

Four national transcript data sets were analyzed to determine the following: vocational education participation of high school graduates declined 1982-1992, academic participation increased, vocational credits completed fell by one-third, and fewer advanced vocational courses were completed. Reliability, validity, and cost effectiveness of using…

Studied the possibility of using large-scale data and methods to study classroom practices in reading comprehension using data from the National Assessment of Educational Progress. Findings suggest that such studies are both feasible and necessary. (SLD)

The purpose of this study was to examine patterns of computer use in U.S. schools and the relation of computer use to academic achievement in mathematics, reading, and writing. The report discusses methodological issues and presents the results of analyses of the social distribution of computer use and the relation of computer use to academic…

Findings on alternative procedures for evaluating measures of achievement in individual data packages at the National Assessment of Educational Progress are presented with their methodological implications. The need for secondary analysts to be aware of the organization of the data, and positive and negative features are discussed. (Author/CM)

The organization of data at the National Assessment of Educational Progress (NAEP) is undergoing a significant transition from a system designed only for national assessment purposes to one designed both for assessment and a variety of academic research interests. The advent of NAEP public-use data files opens up many possibilities for those who…

The National Assessment of Educational Progress in-school sampling design is a three-stage stratified design. Stratification variables include region, size of community and socioeconomic status. The three levels of sample selection are Primary Sampling Units (PSUs), schools and students. In general, two and sometimes three PSUs are selected from…

A study sought to determine the relationship between vocational course taking and academic achievement as measured by the 1990 National Assessment of Educational Progress (NAEP). Analysis of the data measured by the NAEP shows a consistent inverse relationship between vocational course taking and NAEP assessment scores. The relationship holds for…

Identifies trends in educational achievement in the 1970s. Presents hypotheses concerning the relationship between research and gains/declines in educational achievement during that period. Discusses a project for individualized learning programs and its theoretical rationale, and describes a research project based on that educational improvement…
