A methodology for busing to achieve school desegregation is described. Two different approaches are proposed: a student interracial contact score and a quota method. Travel time and number of children bused are proxies for busing costs. Useful data include travel time, school capacity, and student residences for each region and level of school. A…

Presents a review of microcomputer-based software packages that have been designed for Operations Research, Management Science, and Production and Operations Management. Listed for each package are price for student use, minimum system requirements needed to run the package, and maximum capability constraints. (PK)

Presents a structural supply/demand model for enrollment places in parochial schools and uses it to evaluate alternative voucher policy designs. Uses the model's estimated parameters to simulate effects of differently sized and targeted vouchers on public and private school attendance, districts' fiscal status, and public educational costs.…

This paper presents an introduction to the use of latent trait models for the estimation of domain scores. It was shown that these models provided an advantage over classical test theory and binomial error models in that unbiased estimates of true domain scores could be obtained even when items were not randomly selected from a universe of items.…

This paper reports the results of a Monte Carlo investigation of Type I errors in the single group repeated measures design where multiple measures are collected from each observational unit at each measurement occasion. The Type I error of three multivariate tests were examined. These were the doubly multivariate F test, the multivariate mixed…

Approximately 1200 Danish school children aged 8, 11, and 14 participated in a questionnaire study under the caption, "Why I like to read." Data from Denmark formed part of an international study, in which 12 other countries used the same questionnaire to explore various functions of reading and to compare them over different countries.…

Three test-analysis models were used to analyze three types of simulated test score data plus the results of eight achievement tests. Chi-square goodness-of-fit statistics were used to evaluate the appropriateness of the models to the four kinds of data. Data were generated to simulate the responses of 1,000 students to 36 pseudo-items by…

Alternative mathematical models for scoring and decision making with criterion referenced tests are described, especially as they concern appropriate test length and methods of establishing statistically valid cutting scores. Several of these approaches are reviewed and compared on formal-analytic and empirical grounds: (1) Block's approach to…

Three methods of item selection were used to select sets of 38 items from a 50-item verbal analogies test and the resulting item sets were compared for internal consistency, standard errors of measurement, item difficulty, biserial item-test correlations, and relative efficiency. Three groups of 1,500 cases each were used for item selection. First…

Six approaches to assessing test item bias were examined: transformed item difficulty, point biserial correlations, chi-square, factor analysis, one parameter item characteristic curve, and three parameter item characteristic curve. Data sets for analysis were generated by a Monte Carlo technique based on the three parameter model; thus, four…

Unlike the past models guiding cross-cultural psychological research, a new paradigm facilitates multiple level investigations by incorporating both culture-specific (nested) and culture-general (crossed) independent variables within its partially-hierarchical framework. Based upon the generalizability analysis, this model generates sequential…

A key factor in educational planning is providing for an adequate and appropriate supply of teachers for future occupational education needs. This study develops an economic demand and supply model for vocational teachers in secondary schools, a model of the market for teacher services. Data for the study were taken from census reports and from…

This report describes some models the author developed to investigate the simultaneous interaction of decisionmakers in a province-wide educational system and to help formulate educational policy for achieving specified enrollments and expenditures. In chapter one, the author describes the models that examine the process of simultaneous…

Alternative ways of analyzing data from Aptitude Treatment Interactions were examined over a two-year period. In light of past arguments the author maintains that the questions surrounding aggregation have been badly posed and that the customary methods of analysis were either incorrect or subject to misinterpretation. Therefore, the majority of…

The results of a study which used the regression discontinuity model in the analysis of criterion-referenced test data are presented and inherent drawbacks in the use of the regression discontinuity model with this type of data are discussed. The discussion is based on the results of an analysis of data collected in the Mesa, Arizona School…
