When the three-parameter logistic model and item response theory are used to analyze Graduate Management Admission Test (GMAT) data, there are problems with the assumption of unidimensionality. Linear factor analytic models, exploratory factor analysis programs, and the comparison of item parameter estimates for heterogeneous and homogeneous…

This study to assess the current situation of Mexican immigrants in California and project future possibilities constructs a demographic profile of the immigrants, examines their economic effects on the state, and describes their socioeconomic integration into California society. Models of immigration/integration processes are developed and used…

A biography for elementary school students of Patrick Des Jarlait (Ojibwe), an American Indian painter, includes photographs of the artist and some of his work. A teacher's guide following the bibliography contains excerpts from the artist's published reminiscences about his childhood, learning objectives and directions for teachers, suggested…

A biography for the elementary grades of Charles Huntington (Ojibwe), an American Indian sculptor, includes photographs of the artist and some of his work. A teacher's guide following the bibilography contains information on sculpture and the Ojibwe people, suggested activities for learning about sculpture and sculptors, learning objectives and…

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.…

Multidimensional item difficulty (MID) is proposed as a means of describing test items which measure more than one ability. With mathematical story problems, for instance, both mathematical and verbal skills are required to obtain a correct answer. The proposed measure of MID is based upon three general assumptions: (1) the probability of…

A model was developed out of a need to help women move toward a more authentic existence. It was intended to help women go beyond the level of awareness in their present quest for self-determination, to make full use of their lives, to challenge their capabilities, and to reach for new horizons. The model involves both an unlearning and a…

This collection contains three studies of the relationship between incentives, learning, and employability. The first study, "Incentives, Learning, and Employability," by John Bishop, models students' choices concerning what to learn and how much effort to spend learning it in terms of the outcome of a comparison of benefits and expected costs and…

This book presents activities developed for grades 6-10 in creating string designs on polygons and polyhedra. They are designed for use as enrichment materials, each having step-by-step instructions and are arranged from easiest to most difficult, and marked accordingly. The pages are punched and perforated. Many activities are followed by related…

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…

A Monte Carlo study of five indices of dimensionality of binary items used a computer model that allowed sampling of both items and people. Five parameters were systematically varied in a factorial design: (1) number of common factors from one to five; (2) number of items, including 20, 30, 40, and 60; (3) sample sizes of 125 and 500; (4) nearly…

This paper reviews the research and theories on ethnic identity development, and draws some implications from these ideas for improving curriculum design for, and instructional effectiveness with, ethnically different students, especially Black Americans. The paradigm of "the developmental stages of ethnic identity transformation"…

This document is intended to provide evaluation researchers with information about vocational education as a substantive area to be evaluated, existing methodologies for evaluating vocational education programs, and the theoretical basis for a proposed evaluation method termed critical inquiry. Addressed in the individual chapters of the monograph…

Data from two national surveys originally designed to measure public attitudes toward science and technology were examined to determine the relationships among several variable characteristics of the survey population and their attentiveness to local school politics. Survey respondents were divided into two groups: those who indicated they were…

Addressing the lack of cooperation between early intervention programs and the rural health community, this monograph presents eight papers by educators and health professionals who identify specific problems and offer solutions in the form of effective collaboration techniques and model programs. Papers by Susan Hastings and Stewart Gabel…
