This study investigated construct validity and factorial invariance of a performance assessment of reading comprehension and writing proficiency through a multitrait-multimethod (MTMM) structure using confirmatory factor analysis. The performance assessment was administered to 1,023 fifth and sixth graders. Interrater reliability was examined for…

"Seeing Fractions" is an instructional unit for teachers in California that was trial tested in about 30 classrooms, grades 4 through 6 with diverse student populations, and designed to help students become aware of the variety of ways in which fractions are commonly used. The Introduction includes an overview of fractions and what…

Item response theoretic methods are applied to the measurement of achievement of students from various instructional backgrounds. This extended item response theory (IRT) approach serves as a tool for studying instructional bias, or instructional sensitivity. The model maintains the form of an IRT model, but has parameters that quantify the extent…

The issues of achieving school desegregation and providing programs for students with special needs, while at the same time facing enrollment declines, have forced school administrators to improve techniques for projecting demand. This paper describes a new procedure that combines forecasting of enrollments and management of facilities and that…

The validity of American College Testing Program (ACT) test scores and self-reported high school grades for predicting grades in specific college freshman courses was studied. Specific course grades are typically used to place students in remedial, standard, or advanced classes. These placement decisions, in turn, have immediate implications for…

This study analyzes the effectiveness of a "guaranteed tax base" (GTB) as a reform measure designed to reduce the traditional heavy reliance of school financing on local property tax revenues and to help equalize per pupil expenditures across districts. Such measures call for matching locally raised tax dollars with state aid and…

Latent trait theory supposes that, in testing situations, examinee performance on a test can be predicted (or explained) by defining examinee characteristics, referred to as traits, estimating scores for examinees on these traits and using the scores to predict or explain test performance (Lord and Novick, 1968). In view of the breakthroughs in…

The impact of Brown University on the economic base of Providence, Rhode Island and on the state was studied. Data are based on 1978 university and public records and results of a 1976 university survey, adjusted by Consumer Price Indexes. A set of mathematical models was used to measure effects of the university on three major sections of the…

Goodness of fit of raw test score data were compared, using two latent trait models: the Rasch model and the Birnbaum three-parameter logistic model. Data were taken from various achievement tests and the Scholastic Aptitude Test (Verbal). A minimum sample size of 1,000 was required, and the minimum test length was 40 items. Results indicated that…

High school and college grades are suggested to have the nature of ordinal scales rather than interval scales; hence the median is the appropriate and preferred average, rather than the mean. The use of a median grade point average has some of the major advantages of pass-fail grading. Assuming grades to be ordinal rather than interval data…

To calculate the economic benefits of schooling and compensatory education, a statistical model estimated the effects of schooling and literacy on earnings and employment. The literacy measure was obtained for a probable sample of the U.S. population in 1972, from the National Reading Survey. The measure was administered with a background…

As presented in this report the basic purpose of CAIR (Computer-Aided International Relations Teaching) is to introduce university students and policy analysts in government agencies to substantive data analysis in the field of international studies. The student will be exposed to quantitative political science, learn the role and limitations of…

Short-term forecasting methods for assessing the number of students finishing schooling in France, Germany, Ireland, the Netherlands, and the United Kingdom are reviewed. Types of data that are available for each country are discussed, as well as suggestions for data that need to be collected for more efficient forecasting. (Author/IS)

This document contains four papers on aeronautics education, research, and partnerships that partly supported through the Aeronautics Education, Research, and Industry Alliance (AERIAL). The paper "2002 AERIAL Monograph" (Brent D. Bowen, Jocelyn S. Nickerson, Mary M. Fink, et al.) presents an overview of research and development in the…

A model for estimating the effect of public policies on the demand for higher education is presented, with attention focused on the influences of public policy and the economic environment, and the interaction of these factors with student ability and parental income. Policy instruments are tuition, admissions requirements, location of different…
