This study compares the ability of the multiple indicators, multiple causes (MIMIC) confirmatory factor analysis model to correctly identify cases of differential item functioning (DIF) with more established methods. Although the MIMIC model might have application in identifying DIF for multiple grouping variables, there has been little…

Although the Black-White scoring gap on the Scholastic Assessment Test closed significantly between 1976 and 1988, it has widened since 1988. Discusses this widening racial scoring gap, offering a series of articles that discuss social science research which shows that the test scoring gap is not the result of any innate intellectual inferiority…

Perceived self-efficacy (SE) for eating fruit and vegetables (FV) is a key variable mediating FV change in interventions. This study applies item response modeling (IRM) to a fruit, juice and vegetable self-efficacy questionnaire (FVSEQ) previously validated with classical test theory (CTT) procedures. The 24-item (five-point Likert scale) FVSEQ…

Eight independent variables (differential item functioning [DIF] detection method, purification procedure, item response model, mean latent trait difference between groups, test length, DIF pattern, magnitude of DIF, and percentage of DIF items) were manipulated, and two dependent variables (Type I error and power) were assessed through…

In the social sciences, evaluating the effectiveness of a program or intervention often leads researchers to draw causal inferences from observational research designs. Bias in estimated causal effects becomes an obvious problem in such settings. This article presents the Heckman Model as an approach sometimes applied to observational data for the…

An increasingly popular test format allows examinees to choose the items they will answer from among a larger set. When examinee choice is allowed fairness requires that the different test forms thus formed be equated for their possible differential difficulty. For this equating to be possible it is necessary to know how well examinees would have…

A study was conducted at College of the Canyons (COC) in Santa Clarita, California, to provide preliminary data in monitoring for disproportional impact of placement into basic skills courses for various demographic groups. The study was designed to ascertain whether different levels of basic skills courses differ significantly for students in…

Standard errors and bias of unidimensional and multidimensional ability estimates were compared in a factorial, simulation design with two item response theory (IRT) approaches, two levels of test correlation (0.42 and 0.63), two sample sizes (500 and 1,000), and a hierarchical test content structure. Bias and standard errors of subtest scores…

A "Fundamentals of Speech Communication" course is required of all college students, and upon completion of such a course students should possess those basic speaking and listening skills necessary to complete successfully their college educations. With a view toward developing a new, more effective listening test, a study examined…

This paper focuses on New Mexico's high-risk Indian children and programs. Specifically, Western New Mexico University has been involved with the Gallup/McKinley public school district, the largest school district (5,000 square miles) in the United States (larger than New Jersey) with a school population that is 73% Indian. This paper examines…

This study examined major characteristics of instruments commonly used in statewide teacher certification procedures and the possible relations of these characteristics to the uneven success rate among minority teaching candidates. The study analyzed raw scores and selected variables associated with 63 white female candidates who took the Georgia…

The Adult Performance Level (APL) project, which developed and validated a series of objectives for adult functional competency free from school-based notions of literacy, is the most widely accepted approach to adult literacy and adult literacy education in the United States today. Yet a review of the project and its impact reveals that the APL…

The paper reviews the literature on assessment of gifted minority students, focusing first on the importance of appropriate assessment methods, and then on research on specific approaches used to identify gifted Black, Hispanic (mainly Mexican-American), Asian/Pacific, and American Indian students. A discussion section cites five common elements…

Differential responses to Female and Male Lawyer scale items on the Strong-Campbell Interest Inventory (SCII) were analyzed for 67 male and 35 female law students. The results are discussed. Because there is an implicit bias in maintaining separate sex scales, the author suggests the SCII should be considered an intermediate step to a combined…

In the first of these three articles, methods for reporting vocational interests which do and do not reflect sex role stereotypes are examined. The second article is a reply to problems noted in the first article, and the third article is a rebuttal by the first authors. (Author/HMV)
