In this article some results are presented relating to the dimensionality of instruments containing polytomously scored as well as dichotomously scored items, concentrating on the 1992 National Assessment of Educational Progress' (NAEP) mathematics and reading assessment data and several simulated datasets. The maximum likelihood factor analytic…

Several regression methods were examined within the framework of weighted structural regression (WSR), comparing their regression weight stability and score estimation accuracy in the presence of outlier contamination. The methods compared are: (1) ordinary least squares; (2) WSR ridge regression; (3) minimum risk regression; (4) minimum risk 2;…

This paper outlines procedures used to derive variables from data in the National Survey of Postsecondary Faculty; these variables were then used to create measures not expressly included as items in that survey. The derived variables were used to examine faculty satisfaction in two contexts: first, the complexity of satisfaction, and second, the…

Responses to previously calibrated items administered in a computerized adaptive testing (CAT) mode may be used to recalibrate the items. This live-data simulation study investigated the possibility, and limitations, of on-line adaptive recalibration of precalibrated items. Responses to items of a Rasch-based paper-and-pencil licensure examination…

Approaches to sampling are suggested for use by states in reporting more effectively on the completers and leavers in vocational education programs. Following an introductory chapter, six others outline the proposed plan for followup studies. Chapter 2, a task outline for a proposed ongoing sampling survey, divides the first three of the followup…

This report lays out the design for the Evaluation of Reading Comprehension Interventions, which is assessing supplemental reading comprehension programs for fifth-grade students in Title I schools. The key design parameters are described. The report itself provides the rationale for these decisions and discusses design and measurement issues,…

This paper addresses statistical aspects of the No Child Left Behind (NCLB) Act (Bush, 2001), with the following goals: to further the discussion on how gaps in performance might be defined and to offer candidate gap estimators, to evaluate candidate gap estimators with respect to three separate student performance measures, to provide…

In the 1970s and 1980s, the National Assessment of Educational Progress (NAEP) built a longitudinal record as the Nation's Report Card based on periodic brief assessments of a modest but representative sample of the nation's students. In 1990, data collection was expanded from a sample of 10,000 students in each grade and subject area to 100,000…

The National Household Education Survey (NHES) is a telephone interview survey that has been conducted in the spring of 1991, 1993, 1995, 1996, and 1999. The 1999 NHES was a compilation of survey items from previous years that included three interviews, resulting in three data files. One of these components was the Youth Interview, in which…

Generalizability theory is used to examine the psychometric characteristics of the Listening and Writing Tests developed by American College Testing for its Work Keys program. Results with samples of 50 suggest the desirability of a minimum number of the tests' tape-recorded messages and the use of at least 2 raters. (SLD)

The social/behavioral characteristics of 63 preschool children with low and high language abilities were observed for 60 min during teacher-directed structured activities and 60 min during child-directed unstructured activities in Head Start classrooms. Children with low language were observed to have significantly higher rates of disruptive…

Purpose: This research provides state policy makers and others interested in developing needs-based reimbursement models for Medicaid-funded assisted living with an evaluation of different methodologies that affect the structure and outcomes of these models. Design and Methods: We used assessment data from Medicaid-enrolled assisted living…

This article discusses the research potential for some of the National Center for Educational Statistics' data sets, specifically those focused on junior and senior high school students. All share some characteristics, but it is the most recent (National Education Longitudinal Study: 1988) (NELS:88) which is the most comprehensive. Since data is…

In August 1996 Jay P. Greene, Paul E. Peterson, and Jiangtao Du, with Leesa Boeger and Curtis L. Frazier, issued a report called "The Effectiveness of School Choice in Milwaukee." The report, referred to as GPDBF, presented data that indicated that low-income minority students in their third and fourth years of participation in the…

Issues related to between-class and within-class decomposition of achievement variance and the change of this decomposition over the course of the eighth-grade were examined using the Second International Mathematics Study (SIMS, 1985), a study in which there was a nested or hierarchical data structure of students within classes, within schools,…
