This study was designed to increase knowledge of the functioning of item bias techniques in detecting biased items. Previous studies have used computer-generated data or real data with unknown amounts of bias. The present project extends previous studies by using items that are logically generated and subjectively evaluated a priori to be biased…

This study describes and evaluates key bibliometric patterns in the articles published by the former "Journal of Education for Librarianship" (JEL) during its first 24 volumes of existence from 1960 to 1984. Data from each issue of JEL were collected and analyzed using a statistical analysis software package, SPSSx (Statistical Package…

Ways in which the Statistical Package for the Social Sciences (SPSS) can be used to perform some Rasch analyses are described in detail. It is shown how SPSS and a set of item calibrations can be used to estimate person abilities, standard errors of measurement, test characteristic curve, test information curve, classification consistency on a…

To determine if equal raw scores have the same "meaning" for students tested "in" and "out-of-level," four "out-of-level" grade groups who took the Vocabulary, Reading, and Mathematics Concepts subtests of the Iowa Tests of Basic Skills typically administered to fifth graders were compared to "in…

Twelve tests of reading and math at the elementary level are classified according to a model which makes a distinction between criterion and domain tests. Score reporting and item analysis techniques are discussed. It is argued that most objectives-referenced tests do not specify their domains sufficiently to make interpretations more general than…

An approach for multiple factor analysis of dichotomized variables is presented based on distribution of first and second order joint probabilities of binary scored items. The estimator is based on the generalized least squares principle. Standard errors and a test of the fit of the model is given. (Author/RC)

A new system of order analysis, developed by Takeya and called Item Relations Structure Analysis (IRSA), was described and used for examining the structural relations among a set of 24 items on the addition and subtraction of fractions. A diagraph showing 16 chains of items that had discernibly common features was generated by this method, and…

Two studies are presented in this report. The first is titled "Empirical Studies of Multilevel Approaches to Test Development and Interpretation: Measuring Between-Group Differences in Instruction." Because of a belief that schooling does affect student achievement, researchers have questioned the empirical and measurement techniques…

An outline of strategies that can be used to diagnose and remediate the test-taking problems of nursing students has been adapted from an "Outline of Test-Wiseness Principles" conceived by J. Millman, C. H. Bishop, and R. Ebel. The outline consists of two parts: elements independent of the test constructor or test purpose, including time-using,…

Presented is an investigation of the item and factor characteristics which make up Forms 8, 9, and 10 of the Armed Services Vocational Aptitude Battery (ASVAB). Data on the ASVAB forms were collected from mulitary enlistment applications at 20 Armed Forces Examining and Entrance Stations. Item and factor analyses were conducted on samples equated…

A three-year study aimed at measuring the English speaking proficiency of Test of English as a Foreign Language (TOEFL) candidates on a direct basis is described. A variety of "semi-direct" testing formats (involving test stimuli delivered by tape recording and accompanying booklet, with examinee speech tape recorded for evaluation) were…

The preparation and use of an objective strength analysis report (OSAR) from the Iowa Test of Basic Skills (ITBS) are described. The OSAR was designed to answer two needs: (1) a format which allows the school to easily answer the question "which reading objectives need more emphasis and/or better materials or techniques in order to raise its…

This study describes the role of an advisory panel of minority educators in the development of the seventh edition of Stanford Achievement Test (SAT) and the second editions of Stanford Early School Achievement Test (SESAT) and Stanford Test of Academic Skills (TASK). Detailed information on the formation of this panel and the review process in…

A logistic model was used to generate data to serve as a proxy for an immediate retest from item responses to a fourth grade standardized reading comprehension test of 45 items. Assuming that the actual test may be considered a pretest and the proxy data may be considered a retest, the effect of regression was investigated using a percentage of…

Sixteen item statistics recommended for use in the development of criterion-referenced tests were evaluated. There were two major criteria: (1) practicability in terms of ease of computation and interpretation and (2) meaningfulness in the context of the development process. Most of the statistics were based on a comparison of performance changes…
