This study examined the reliability and validity of scores from the Multidimensional Inventory of Black Identity with 550 Euro-American, 112 Latino, and 41 Native American undergraduates. Data for the Centrality, Private Regard, and Public Regard scales indicate that these scores have construct validity. Scores have acceptable Cronbach alpha…

Analogy items from the Scholastic Aptitude Test (SAT) were evaluated for differential performance by black and white examinees. Black and white examinees were first matched for overall SAT-V scores prior to conducting item analyses. A content and psycholinguistic analysis of 220 disclosed SAT analogy items from 11 test forms was performed.…

A scaling procedure is proposed, based on item response theory (IRT), to fit non-hierarchical test structure as well. The binary scores of a test of English were used for calculating the probabilities of answering each item correctly. The probability matrix was factor analyzed, and the difficulty intervals or estimates corresponding to the factors…

This paper reports on the process of modifying the ModelCreator item generation system to produce output in multiple languages. In particular, Japanese and Spanish are now supported in addition to English. The addition of multilingual functionality was considerably facilitated by the general formulation of our natural language generation system,…

The factor structure and reliability of an instrument for measuring attitudes of preservice teachers toward science were studied as part of a 5-year project at the University of Wyoming (Laramie) to improve the teaching of science at the elementary school level. The Attitudes towards Science and Scientists Scale (ATSSS) of J. R. Cummings (1969)…

Results of new research into the anomalous results of the 1986 reading portion of the National Assessment of Educational Progress (NAEP) are reported. The original analysis of the 1986 data indicated that the estimated performance level of 9- and 17-year-old students had dropped dramatically since 1984, whereas the performance of 13-year-olds had…

The exploratory and secondary phases of the "Organisation for Economic Cooperation and Development (OECD) project to develop a set of international indicators based on comparable educational data is described in this report. Voluntary networks in 24 OECD member countries are developing a cohesive conceptual framework based on a review of…

Nedelsky (1954) has suggested a procedure for determining the minimum passing score on a multiple-choice test. In this procedure expert judges estimate the probable score of a minimally competent examinee. The technique does not refer to the students' performance data. The purposes of this paper are: (1) to introduce a modification to the Nedelsky…

This research study investigates the validity of the Teacher Locus of Control Scale (TLCS) in a different cultural environment. The scale, developed in the United States by Taylor et al., measures teachers' beliefs about their own potential to influence student performance and classroom events. Specifically, the study investigates the…

Newman (1984) examined the causal relations between math self-concept and math achievement in an 8-year longitudinal study using Linear Structural Relations (LISREL) analyses. He concluded that math self-concept did not influence subsequent math achievement. However, the study suffered in that math self-concept was inferred from a single-item…

This study compared student performance on language-usage test items presented in two different formats: as discrete sentences and as items embedded in passages. American College Testing (ACT) Program's Assessment experimental units were constructed that presented 40 items in the two different formats. Results suggest item presentation may not…

ASCAL is a microcomputer-based program for calibrating items according to the three-parameter logistic model of item response theory. It uses a modified multivariate Newton-Raphson procedure for estimating item parameters. This study evaluated this procedure using Monte Carlo Simulation Techniques. The current version of ASCAL was then compared to…

The problem of measuring growth across the target grade and, typically, the two adjacent grades, concerns most developers of standardized, norm-referenced achievement tests, particularly at the item selection stage. Opinion is divided on whether to retain or drop items that do not get easier from grade to grade. The controversy has focused on…

This study compares the contribution to measurement accuracy of the verbal score of each of four verbal item types included in the Graduate Record Examinations (GRE) General Test. Comparisons are based on item response theory, a methodology that allows the researcher to look at the accuracy of individual points on the score scale. This methodology…

A sample of slightly over 1,500 students drawn from even-numbered grades in public schools of the U.S. Virgin Islands (USVI) were given the 1973 edition of the Stanford Achievement Test (grades 2, 4, 6, and 8) and the Test of Academic Skills (grades 10 and 12) in an attempt to assess student academic achievement in the basic skill areas of…
