Analysis of a two-way sample of means is considered when corresponding population means are believed a priori to satisfy a partial order restriction. Simulation and the Gibbs sampler are used to summarize posterior distributions, and the posterior distribution is used to predict GPAs of first-year students at University of Iowa. (SLD)

A study of the relationship between first-year results for 115 Dutch medical students and achievement during medical school was studied using an item-response theory model for the longitudinal measure of change with stochastic parameters (developed by Albers et al., 1989) indicates that a low rate of growth in the first year persists.

Describes the College of Lake County's (Illinois) development of an enrollment projection process that satisfies the need for information for institutional planning and budget forecasting. The process includes statistically driven projections and adjustments to the projections that reflect unique conditions within the disciplines and requires much…

In recent years, semiotics has become an innovative theoretical framework in mathematics education. The purpose of this article is to show that semiotics can be used to explain learning as a process of experimenting with and communicating about one's own representations (in particular "diagrams") of mathematical problems. As a paradigmatic…

In the Southern Regional Education Board (SREB) region, state and local governments spend about 10 percent of their combined annual budgets on colleges and universities. Whether this is the right funding level during a time of growing enrollments, when states are working to boost education participation and close achievement gaps, is a question…

This report is a complete analysis of employment trends in K-12 education. The report provides detailed information on Alaska public school enrollment, Alaska's teaching work force, the supply of teachers from local universities, and the current composition and turnover rates and reasons of Alaska teachers. The near-term demand for teachers is not…

The research for this study was undertaken to analyze the New York State 11th grade United States History Regents exams through conducting a content analysis of the types of multiple-choice questions asked in Part I of the tests with a particular emphasis on the variety of questions asked regarding women and race. Because these tests stand at the…

Using statistical data collected during a 30-year period, the article reports on the significant movement of females into all of the line administrative positions in the largest school districts in the country (by student population) since the passage of Title IX with one notable exception, that of superintendent. The position of superintendent…

The purpose of this study was to align verbal descriptions of test takers' language performance with distributions of the numerical scores they received on the three sections (Listening Comprehension, Structure and Written Expression, and Reading Comprehension and Vocabulary) of the Test of English as a Foreign Language (TOEFL). The descriptors of…

Comparative results are presented for procedures recently appearing in literature related to standard setting on the National Assessment of Educational Progress--the paper selection method and the contrasting group method. For this comparison, a probabilistic model with normal distribution of performance and a six-point scale were assumed. The…

The empirical performance of the technique proposed by P. O. Johnson and J. Neyman (1936) (the JN technique) and the modification of R. F. Potthoff (1964) was studied in simulated data settings. The robustness of the two JN techniques was investigated with respect to their ability to control Type I and Type III errors. Factors manipulated in the…

Factor analysis is the traditional method for studying the dimensionality of test data. However, under common conditions, the factor analysis of tetrachoric correlations does not recover the underlying structure of dichotomous data. The purpose of this paper is to demonstrate that the factor analyses of tetrachoric correlations is unlikely to…

This report is based on data gathered in a 1982 survey of college and university libraries conducted as part of the Higher Education General Information Survey (HEGIS). The survey had a 91% response rate from a universe of 3,326 colleges and universities. The 1982 data categories cover the following time frames: staff and library hours as of fall…

Extended caution indices (ECI) specify the degree of confidence that can be placed in an individual's test score by analyzing patterns of item response. Among the most promising of such indices are the standardized ECIs. Contrary to the literature, several instances were found, in a previous study, of nonnormal distributions of ECIs with samples…

This publication reports findings of the 1982 Child Welfare League of America's (CWLA) annual study of salaries and personnel issues conducted with the League's voluntary member agencies. Survey forms were sent to 220 voluntary accredited and provisional members of the CWLA and to the Florence Crittenton Division of the CWLA. Each agency was asked…
