Longitudinal data analysis has been widely employed to examine between-individual differences in within-individual changes. One challenge of such analyses is that the rate-of-change is only available indirectly when change patterns are nonlinear with respect to time. Latent change score models (LCSMs), which can be employed to investigate the…

This longitudinal study of 78 Canadian English-speaking students examined the applicability of the stability, cumulative, and compensatory models in reading comprehension development. Archival government-mandated assessments of reading comprehension at Grades 3, 6, and 10, and the Canadian Test of Basic Skills measure of reading comprehension…

In 2013-14, Letterland had strong implementation, with moderate to high fidelity within approximately 90% of Wake County Public School System (WCPSS) K-1 classrooms. The impact of Letterland on students' reading achievement was neutral to positive. A significantly higher percentage of WCPSS kindergarten students were at or above benchmark mid-year…

The National Association of State Directors of Special Education (NASDSE, 2005) defines response to intervention (RTI) as the practice of providing high-quality instruction and intervention based on a student's needs, changing instruction and/or goals through frequent monitoring of progress, and applying the student response data to important…

As teachers, administrators, and members of intervention teams use student performance data to inform instructional decisions and monitor implementation of tiered instruction in a Response to Intervention (RTI) model, assuring fidelity of implementation or treatment integrity continues to be a challenge. This article describes how one school…

Xu and von Davier (2006) demonstrated the feasibility of using the general diagnostic model (GDM) to analyze National Assessment of Educational Progress (NAEP) proficiency data. Their work showed that the GDM analysis not only led to conclusions for gender and race groups similar to those published in the NAEP Report Card, but also allowed…

The teaching of reading is an important aspect of the total Adult Basic Education (ABE) program. The basic problem was: How is the teaching of reading in Nebraska being carried out? In trying to answer this question the document lays the groundwork by opening with a review of related literature and then discusses in detail the type of data…

The longitudinal impacts on school change and student achievement of implementing varied Comprehensive School Reform (CSR) models was investigated in 12 elementary schools in diverse geographic locations. Each school was individually matched and compared to a demographically similar control school on measures of school climate, teacher…

Poor performance on tests of reading comprehension could be the result of weak word-recognition skills, inconsistent attention (ADD), or a combination of the two. Identifying the source of the reading disability (RD) reliably has been difficult because inconsistent attention interferes with reading and weak word recognition skill makes attention…

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…

This study was conducted to evaluate the tests developed by elementary foreign language teachers of French, Japanese, and Spanish in a school district in South Carolina. The tests were designed to determine the level of end-of-year student learning and to provide a basis for evaluating the curriculum of each of the three languages. The French and…

A procedure is demonstrated for constructing tables showing, for each score on a commercial reading achievement test, the percentage of real-world materials that the testee is likely to comprehend with at least a criterion level of proficiency, the percentages of students in a local or national sample who can competently comprehend a given…
