Many researchers have suggested that the cause of differential item functioning (DIF) can in part be due to the misspecification of the supporting trait distribution (STD). This paper demonstrates how a unidimensional item response theory (IRT) calibration of response data, generated from a two-dimensional IRT model, results in DIF when the…

Recent theoretical developments in cognitive psychology imply both a need and a possibility for methodological development. In particular, the theory of problem solving proposed by Allen Newell and Herbert A. Simon (1972) provides the rationale for a new empirical method for the processing of think-aloud protocols--trace analysis. A detailed…

Procedures for developing and validating a modified cloze test are described. The multiple-choice cloze procedure was developed to aid in the rapid placement of college freshmen who are students of English as a second language. It was designed to overcome some problems in the original cloze test, to reduce anxiety, and to be machine scored. The…

New legislation in 1972 shifted the emphasis of the California Assessment Program (CAP) from traditional every pupil achievement testing to a more efficient multiple-matrix testing design, under which a broad spectrum of skills could be surveyed without undue expenditure of educational resources. Scale score reporting was introduced to the grade 6…

A 113-item survey instrument was designed to measure the class climate perceptions of 20,157 students in grades 7-12 as part of the "A Study of Schooling" research project. The 29 constructs of the questionnaire focused on students' interpersonal needs, classroom procedures, and instructional practices. Survey items were written in the first…

A strategy for overcoming problems with the Rasch model's inability to handle missing data involves a pairwise algorithm which manipulates the data matrix to separate out the information needed for the estimation of item difficulty parameters in a test. The method of estimation compares two or three items at a time, separating out the ability…

The purpose of this study was to demonstrate the use of confirmatory factor analysis to investigate the existence of item bias in an affective scale measuring self concept. The LISREL IV program was used to detect test item bias and factorial invariance. The ethnic groups compared in the study were Black, Hispanic, and White. The obtained factor…

This manuscript is a report of the third revision of the Maryland Preschool Self-Concept of Scale originally developed by Smith (1977). Two samples of 4-, 5-, and 6-year old children (N = 54 and N = 78) were administered the Maryland Preschool Self-Concept Scale - Revised (MPSS-R). In the first study, the measure was given twice, 3 to 5 weeks…

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…
