Cross-cultural validity studies for psychological instruments may result in overestimation of structure invariance due to some items being scored on more than one scale. This problem, called the common-item effect, is investigated with some data from the literature. (JKS)

Procedures to be applicable in situations in which large numbers of individuals are tested or in situations where multiple measures are taken. (Author/CB)

Binomial models for domain-referenced testing are compared, emphasizing the assumptions underlying the beta-binomial model. Advantages and disadvantages are discussed. A proposed item sampling model is presented which takes the effect of guessing into account. (Author/CM)

Describes two types of criterion-referenced testing that districts can use to measure achievement outcomes of their instructional programs: a random sampling assessment plan and an item-response theory assessment plan. (Author/JM)

A procedure for sampling questions from a universe for repetition of criterion performances is described. Academic and administrative benefits are also noted. Available from: Kenyon College, Gambier, Ohio 43022. (Author/LBH)

This is one of three volumes presenting the procedures and results of a research effort investigating the effects upon student outcomes of training teachers to implement individual study and self-directed study in their classrooms. In this volume correlation matrices drawn from tests of student variables and achievement are presented. Item…

This study was designed to assess the conceptual structure of the Task of Public Education Opinionnaire (TPE). Since the development of the instrument, several psychometric techniques have been formulated. Two of those methods, image component and alpha factor analysis, were applied to the items of the TPE after the correlation matrices were…

Using a computer-based Monte Carlo approach to generate item responses, the results of this study indicate that, when item discrimination indices are considered, item-examinee sampling procedures having the same number of observations have different standard errors in estimating both test mean and test variance. With certain types of tests, a…

A subject by item matrix of test responses is shown to be a useful heuristic in criterion referenced and norm referenced test analysis, and in the teaching of measurement. The pattern of responses within the matrix provides indications of item interactions, weak deceptors, and conventional test statistics. The strong visual analogy between the…

A test of mental arithmetic skills was developed and normed for children in grades one to six. Statistical techniques were used to predict the probability correct for each item and to rank order the items. Students in a given grade took only one level of the test and inferences were made of their performance on those tests which they did not take.…

Item correlations performed between student ratings of instruction in various situations clearly indicate that student ratings are consistent across time, but that this consistency is related to specific educational settings and conditions as well as instructor idiosyncracies. (RC)

Given a loss function, an asymptotic method for optimal test design for a specified target population of examinees is presented. Also, of more practical use, given an existing unidimensional test and target population, a way is presented to find the loss function for which the test is optimal. (NSF)

This document is the fourteenth annual report on the critical successes of the North Carolina Community Colleges published in July 2003. The purpose of this document is to report on the performance measures for purposes of accountability and performance funding. Furthermore, the annual report serves as an evaluation instrument for the System…
