This article on student mobility data in Europe has a double objective: First, it investigates which data on international mobility of students are being compiled and made available--and which are not--both at the international, the national, and the programme level. Second, it presents some of the student mobility data identified, and--based on…

The Grammar, Spelling, and Punctuation (GSP) test is administered to students in the College of Communication at the University of Texas, Austin, as a means of determining eligibility to register for certain courses in journalism, broadcasting, and advertising. The test was administered in a paper-and-pencil version to 16 students and in a…

The inherent methodological problem in conducting research at multiple sites is how to best derive an overall estimate of program impact across multiple sites, best being the estimate that minimizes the mean square error, that is, the square of the difference between the observed and true values. An empirical example illustrates the use of the…

Although perfectly scalable items rarely occur in practice, Guttman's concept of a scale has proved to be valuable to the development of measurement theory. If the score distribution is uniform and there is an equal number of items at each difficulty level, both the elements and the eigenvalues of the Pearson correlation matrix of dichotomous…

Hypothetical data sets are used to demonstrate how canonical correlation methods subsume other commonly utilized parametric methods. Analysis of variance, analysis of covariance, multiple analysis of variance, and multiple analysis of covariance are heavily used by educational researchers. It is concluded that researchers would do well to consider…

Three item response models were evaluated for estimating item parameters and equating test scores. The models, which approximated the traditional three-parameter model, included: (1) the Rasch one-parameter model, operationalized in the BICAL computer program; (2) an approximate three-parameter logistic model based on coarse group data divided…

This study examined the effect of type of correlation matrix on the robustness of LISREL maximum likelihood and unweighted least squares structural parameter estimates for models with categorical manifest variables. Two types of correlation matrices were analyzed; one containing Pearson product-moment correlations and one containing tetrachoric,…

Using nationally representative data generated by the normal, day-to-day operation of schools, this research tested the major conclusions drawn from case studies focusing on principal effectiveness. On the basis of detailed information regarding individual student characteristics and achievements, detailed characteristics of teachers and their…

A primary goal of this study was to determine the extent to which item difficulty was related to item position and, if a significant relationship was found, to suggest adjustments to predicted item difficulty that reflect differences in item position. Item response data from the Medical College Admission Test (MCAT) were analyzed. A data set was…

The discovery of disproportionate minority enrollments in special education classes has been a subject of considerable concern to federal, state, and local education officials alike for the past decade. Because the existence of disproportions is frequently thought to result from discriminatory placement practices on the part of local school…

The study reported in this paper examined whether a disproportionate number of boys and girls in a given grade level at various schools might have an inequitable effect on the mean achievement test scores of those schools. The student population of the Palm Beach County Schools, Florida, reflecting a cross-section of socio-economic backgrounds,…

The focus of this study is on the estimation procedures implemented in BILOG, a computer program. One purpose is to compare the item parameter estimates produced by various procedures available in BILOG. Four different models are used: the one, two, and three parameter model and a three parameter model with common guessing parameters. The results…

Part of a series on student flow in the seven Hawaii community colleges, this report analyzes fall 1975 entering students in their fifth semester. Of a total of 8,979 entering students in fall 1975, 2,342 were registered in fall 1977, and 1,844 had been continuously enrolled over the five semesters. The continuation rate from the previous semester…

The Norfolk, Virginia, city school system had the highest secondary school dropout rate in the State for the 1975-76 academic year. In the study discussed in this paper student dropouts are described from data in their academic files. The wish is expressed that by characterizing dropout prone students, something can be done to save them before…

This publication, an update of previous reports of the same title, provides information on language programs in Canada under the following headings: (1) programs in the nine provinces (excluding Quebec) including a description of minority language and second language education as well as French immersion programs; and (2) programs in Quebec,…
