The variance formula derived for a two-stage sampling design without replacement employs the joint inclusion probabilities in the first-stage selection of clusters. One of the difficulties encountered in data analysis is the lack of information about such joint inclusion probabilities. One way to solve this issue is by applying Hájek's…

Recent research on statewide voucher programs in Louisiana and Indiana has found that public school students that received vouchers to attend private schools subsequently scored lower on reading and math tests compared to similar students that remained in public schools. The magnitudes of the negative impacts were large. A case to use taxpayer…

Effective writing requires mastering grammar. For journalists, this mastery is critical because research shows poor grammar erodes media credibility. College writing instructors say students do not understand basic grammar concepts, and greater numbers of students are enrolling in remedial writing classes. This quasi-experimental mixed methods…

The primary goal of Project M[superscript 2] was to develop and field-test challenging geometry and measurement units for all K-2 students. This article reports on the achievement results for students in Grade 2 at 12 urban and suburban sites in 4 states using the Iowa Tests of Basic Skills (ITBS) mathematics concepts subtest and an open-response…

Since its inception more than four decades ago, the National Assessment of Educational Progress (NAEP) has served as a key indicator of what the nation's students know and can do in academic subjects. NAEP assessments provide a mechanism for putting the achievements of students in all states on a common scale; the assessments also serve as…

"Learning progressions" are one of the most important assessment design ideas to be introduced in the past decade. In the United States, several committees of the National Research Council (NRC) have argued for the use of learning progressions as a means to foster both deeper mastery of subject-matter content and higher level reasoning…

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…

In recent years, as schools have shifted more attention to English language arts and mathematics, several groups have made a plea for renewed attention to civic education for all students. One such group is the Spencer Foundation, which promotes research to improve students' civics knowledge and skills and their dispositions for responsible…

This paper presents an overview of the design features that were developed for the Content Analysis Project. The purpose of the project was to examine the congruence between a state's test in eighth-grade mathematics and that used by the National Assessment of Educational Progress. The results of this analysis were then to be used to determine…

This report presents and compares the results of the first and second art assessments conducted by the National Assessment of Educational Progress (NAEP) in 1974-75 and 1978-79. The achievement and attitudes of approximately 7,500 9-year-olds, 11,000 13-year-olds, and 13,500 17-year-olds were surveyed. The report consists of an introduction to the…

The National Assessment of Educational Progress (NAEP) is compared to the two studies of the National Educational Longitudinal Studies (NELS) Program--the National Longitudinal Study of the Class of 1972 (resurveyed in 1973, 1974, 1976, and 1979) and the 1980 High School and Beyond study (partially resurveyed and retested in 1982). The third phase…
