Describes a study of gender differences in science achievement in England and Wales. Finds that the most pronounced gender differences in favor of males occurred in the higher-level papers taken by more able students, especially in physics. Also, more discriminating questions exhibited larger gender gaps in favor of males. Contains 21 references.…

Research with 96 undergraduates investigated interpretations of a global-evaluation item common to student evaluation forms. Through narratives and semistructured interviews, students described classroom experiences, beliefs about good teaching, and aspects of the evaluation process that influencing their ratings. The item produced multiple…

Subgroup differences are expected on traditional knowledge, skill, ability, and achievement tests. Considers actions to reduce differences and fairly assess individual attributes. Suggests that selection materials assess the full range of relevant attributes using a format that minimizes verbal content as much as is appropriate. Recommends using…

Analyzes simulated performance ratings on a six-point scale by two independent raters to account for nonsystematic error in performance ratings. Results suggest that rater agreement or covariance is not always a dependable estimate of score reliability and that the practice of seeking additional raters for adjudication of discrepant ratings is not…

Content (item) bias on the Mental Processing Scales and the Achievement Scale of the Kaufman Assessment Battery for Children (K-ABC) was investigated with 100 Mexican American and 100 White fifth- and sixth-grade boys and girls. Biases were found against the Mexican American sample. (JBJ)

Validated the Motivation Orientation scales of the Inventory of School Motivation (ISM) (M. Maher, 1984) across Navajo (n=760) and Anglo (n=1,012) students. Findings show that even though the ISM motivation orientation scales are applicable to students of different cultural backgrounds, meaningful cross-cultural comparisons should use the 30 items…

Posits that perceptions of past experience and expectations of the outcomes of future experience can have important consequences for determining young people's educational, career, and life experiences. The lecturer also examines high-stakes test performance and test use as a function of several factors, and traces the history of research on…

The aims of this study were to investigate whether the 6 items of the Physical Appearance Scale (Marsh, Richards, Johnson, Roche, & Tremayne, 1994) show differential item functioning (DIF) across gender groups of adolescents, and to show how this can be done using the multigroup mean and covariance structure (MG-MACS) analysis model. Two samples…

Empirical studies demonstrated Type-I error (TIE) inflation (especially for highly discriminating easy items) of the Mantel-Haenszel chi-square test for differential item functioning (DIF), when data conformed to item response theory (IRT) models more complex than Rasch, and when IRT proficiency distributions differed only in means. However, no…

Exact nonparametric procedures have been used to identify the level of differential item functioning (DIF) in binary items. This study explored the use of exact DIF procedures with items scored on a Likert scale. The results from an attitude survey suggest that the large-sample Cochran-Mantel-Haenszel (CMH) procedure identifies more items as…

Within-family estimates have been considered a remedy to selection bias in estimates of long-run consequences of teen motherhood. A major critique, however, is that heterogeneity within the family might still bias the estimates. Using Swedish data on biological sisters, I revisit the question of the consequences of teenage motherhood. My…

This article compares several procedures in their efficacy for detecting differential item functioning (DIF): logistic regression analysis, the Mantel-Haenszel (MH) procedure, and the modified Mantel-Haenszel procedure by Mazor, Clauser, and Hambleton. It also compares the effect size measures that these procedures provide. In this study,…

The Marlowe-Crowne Social Desirability Scale (MCSDS), the most commonly used social desirability bias (SDB) assessment, conceptualizes SDB as an individual's need for approval. The Balanced Inventory of Desirable Responding (BIDR) measures SDB as two separate constructs: impression management and self-deception. Scores on SDB scales are commonly…

Typically, group differences are analyzed at the subdomain or test level using composite scores. This can mask the effect of individual items across groups. For example, two items from the Physical Self-Description Questionnaire (PSDQ) are worded in terms of internal ("I am good looking") and external ("Nobody thinks Im good looking") frames of…

The juvenile justice system needs a tool that can identify and assess mental health problems among youths quickly with validity and reliability. The goal of this article is to evaluate the racial/ethnic and gender differential item functioning (DIF) of the Massachusetts Youth Screening Instrument-Second Version (MAYSI-2) using the Rasch Model.…
