This paper presents an application of a stochastic approximation EM-algorithm using a Metropolis-Hastings sampler to estimate the parameters of an item response latent regression model. Latent regression models are extensions of item response theory (IRT) to a 2-level latent variable model in which covariates serve as predictors of the…

Every two years the National Assessment of Educational Progress (NAEP), "the Nation's Report Card," reports the nation's average reading and math scores in grades 4 and 8. Despite the strong focus on reading under the 2001 No Child Left Behind law, the recent 2009 reading scores were not statistically different from those of 2007, which…

The Focused Practice Instructional Approach (FPIA) was based on the Environmental Mode of instruction established by George Hillocks' 1986 meta-analysis for writing instruction. The purpose of this study was to clearly define the FPIA approach using the original studies and test if it was significantly effective in fourth grade classrooms using…

In January, 2010, Iowa Kids Count produced a special report that showed long-term trends in Iowa student reading and mathematics scores on the National Assessment of Educational Progress (NAEP), the only source for comparative state information on student achievement. The January report showed a decline in Iowa's ranking since 1992, when the first…

This report presents results from a new quantitative synthesis of research on the effectiveness and validity of test accommodations for English language learners (ELLs) taking large-scale assessments. In 2006, the Center on Instruction published a review of the literature on test accommodations for ELLs titled "Practical Guidelines for the…

A new method for analyzing differential item functioning is proposed to investigate the relative strengths and weaknesses of multiple groups of examinees. Accordingly, the notion of a conditional measure of difference between two groups (Reference and Focal) is generalized to a conditional variance. The objective of this article is to present and…

This paper examines changes in demographic and socioeconomic inequalities in student achievement over the school career, and the extent that these inequalities are accounted for by other influences such as, region and socioeconomic background (where appropriate), school differences and prior achievement. The data analysed are from a longitudinal…

"Why Rural Matters 2013-14" is the seventh in a series of biennial reports analyzing the contexts and conditions of rural education in each of the 50 states and calling attention to the need for policymakers to address rural education issues in their respective states. While it is the seventh in a series, this report is not simply an…

The Nation's Report Card[TM] informs the public about the academic achievement of elementary and secondary students in the United States. Report cards communicate the findings of the National Assessment of Educational Progress (NAEP), the largest continuing and nationally representative assessment of what the nation's students know and can do.…

The purpose of the 2011 NAEP (National Assessment of Educational Progress) Writing Framework is to describe how the new NAEP Writing Assessment is designed to measure students' writing at grades 4, 8, and 12. As the ongoing national indicator of the academic achievement of students in the United States, NAEP regularly collects information on…

In Fall 2008, the Council of Chief State School Officers (CCSSO) conducted an alignment content analysis of the 2007 TIMSS Mathematics and Science education assessments for students at grades 4 and 8 and the 2006 PISA Mathematics and Science Literacy assessments for students at age 15 (i.e., TIMSS--Trends in Mathematics and Science Study,…

The disparity between the results of state accountability tests in reading and the fourth-grade National Assessment of Educational Progress (NAEP) has left many educators dismayed and concerned. In this article the authors describe a comparison of assessment approaches evident in NAEP to the approaches taken in a sample of state tests. The authors…

The general diagnostic model (GDM) utilizes located latent classes for modeling a multidimensional proficiency variable. In this paper, the GDM is extended by employing a log-linear model for multiple populations that assumes constraints on parameters across multiple groups. This constrained model is compared to log-linear models that assume…

Using data from the National Assessment of Educational Progress (NAEP) and the New England Common Assessment Program (NECAP), this report examines how gender gaps differ between Vermont NAEP scores and U.S. NAEP scores and between Vermont NAEP and NECAP scores in grades 4 and 8. Overall and disaggregated by poverty and disability status, gender…

Since 2005, the National Indian Education Study (NIES) has provided educators, policymakers, and the public with information about the background and academic performance of fourth- and eighth-grade American Indian and Alaska Native (AI/AN) students in the United States. NIES was administered in 2005, 2007, 2009, and 2011 as part of the National…
