Presented is a quantitative synthesis of examiner familiarity effects on Caucasian and minority students' test performance. Fourteen controlled studies were coded in terms of methodological quality and race-ethnicity. Caucasian students performed similarly in both familiar and unfamiliar examiner conditions, while Black and Hispanic children…

Demonstrates that a high degree of fairness may be achieved in international comparative research on school achievement, using the Third International Mathematics and Science Study (TIMSS) as an example and employing the methods of advanced pedagogical-psychological diagnosis. Includes references. (CMK)

Previous studies have compared the accuracy of parent, teacher, and clinician ratings of children behavior, especially in diagnostic analysis. However, many have questioned the validity of the tests and the value of each rater. While some research has found differences among raters, few had looked at samples of non-referred children. We wanted to…

One conceptualization of meta-analysis is that studies within the meta-analysis are sampled from populations with mean effect sizes that vary (random-effects models). The consequences of not applying such models and the comparison of different methods have been hotly debated. A Monte Carlo study compared the efficacy of Hedges and Vevea's…

The curriculum innovations in chemistry are often designed to address the important goals of improving student understanding and attitude, with assessment to determine the effects of these innovations. These analyses are psychometrically weak for several reasons, one reason being that the ability to look for the changes over time or for…

In the current study, the child AQ was administered in Japan, to examine whether the UK results for reliability and validity generalize to a different culture. Assessment groups were: Group 1: n = 81 children with Asperger Syndrome (AS) or high-functioning autism (HFA); Group 2: n = 22 children diagnosed PDD-NOS with average IQ; and Group 3: n =…

Two analyses of variance (ANOVA) models for item scores are compared. The first is an items by subject random effect ANOVA. The second is a mixed effects ANOVA with items fixed and subjects random. Comparisons regarding reliability, Cronbach's alpha coefficient, psychometric inference, and inter-item covariance structure are made between the…

Since speech communication evaluators are beginning to adapt the analytic and holistic instruments and methods used for rating written products to oral products and performance, this research review investigated: (1) what the labels "analytic" and "holistic" mean; (2) the theoretical bases of the two scoring approaches; and (3)…

First-, second-, and third-year students enrolled in an introductory educational psychology class at Texas A&M University in College Station were administered either a pencil-and-paper or computerized version of the Strong-Campbell Interest Inventory. The same or other version of the test was administered after 2 weeks. Focus is on equivalence…

A study was conducted at Stark Technical College to compare a normative-referenced test for mathematics placement with a criterion-referenced test that had been used by the college. The study sought to compare statistically the scores of 165 students on the Mathematics Inventory Test (MIT--a criterion-referenced test that had been developed…

A study examined the nature of the questions contained in two major standardized reading comprehension tests in terms of their centrality to the text. It was hypothesized that the use of a discrimination index for item selection would tend to favor relatively trivial questions. Half the reading selections from the Stanford Diagnostic Reading Test…

Four new methods of item analysis were used to select subsets of items which would yield measures of attitude change. The sample consisted of 263 students at Michigan State University who were tested on the Inventory of Beliefs as freshmen and retested on the same instrument as juniors. Item change scores and total change scores were computed for…

Differential Aptitude Test (DAT) scores of 2,622 students who were tested in the 8th, 9th, or 10th grades and who later entered a Minnesota area vocational-technical school were analyzed to determine the relationships between test scores and training program entered. Results are presented. (Author)

Reports a study which investigated the cross-cultural validity, reliability, and distinctiveness of the subscale structure of the Test of Science Related Attitudes (TOSRA). Results from tests of American high school students (N=336) indicated that the seven subscales were highly reliable, but that the discriminant validity was low. (ML)

The indices of item difficulty and discrimination, the coefficients of effective length, and the average item information for both single- and multiple-answer items using six different scoring formulas were computed and compared. These formulas vary in terms of the assignment of partial credit and the correction for guessing. (Author/BW)
