Two estimation procedures for the Rasch Model of test analysis are reviewed in detail, particularly with respect to new developments that make the more statistically rigorous conditional maximum likelihood estimation practical for use with longish tests. (Author/JKS)

Generalizability theory provides the teacher and the researcher with a flexible method for establishing reliability coefficients in tests. This theory is effective in estimating reliability for a set of motor performance test scores. (CJ)

Considers issues surrounding the use of differentiated examinations. Discusses how differentiation may be provided, the wording of questions, and how marks should be given. Highlights some pitfalls of using this approach. Concludes that, although differentiated examinations are possible, they will not always meet the needs of the end range of test…

Applications of Oscar K. Buros' values and convictions to current developments in measurement are considered. Biographical information and Buros' personal philosophy on applied measurement are discussed. The Buros tradition refocuses evaluators' attention on the implications of their work for the end users of measurement results--test users and…

Studies the effect of item order on test scores and completion time. Students scored slightly higher when test items were grouped sequentially (relating to text and lectures) than on tests when test items were grouped by text chapter but ordered randomly, or when test items were ordered randomly. Found no differences in completion time. (Author/LS)

Examines the question of whether cultural and ethnic groups differ in their extreme response style. Studies questionnaire responses of Hispanic and non-Hispanic male Navy recruits and suggests that differences in extreme response style may be attributable to differences in judgment style across the two cultural groups.

Violations of item unidimensionality on language tests produced distorted estimates of person ability, and violations of person unidimensionality produced distorted estimates of item difficulty. The Bejar Method was sensitive to such distortions. (Author)

Determining the optimal number of choices on a multiple-choice test is explored analytically from an information theory perspective. The analysis revealed that, in general, three choices seem optimal. This finding is in agreement with previous statistical and psychometric research. (SLD)

Currently there are at least four pretreatment-posttreatment (pre-post) difference score methods for determining client change. A fifth model, based on a random effects model and multiwave data, represents a growth curve approach and was hypothesized to be more sensitive to detecting significant (p<.05) change than pre-post models. Compares…

Investigates the general factor and uniqueness characteristics of the individual tests of the Woodcock-Johnson Test of Cognitive Ability-Revised (WJTCA-R). Only 2 of the 19 WJTCA-R tests examined had low general factor loadings, while 2 had low uniqueness. All other tests had medium or high uniqueness. Discusses implications for clinical…

Examines the performance characteristics of 83 school-identified learning-disabled children on the Differential Ability Scales. Sixty percent showed a significant standard score discrepancy between the General Conceptual Ability and at least one achievement test. Implications regarding the educational diagnostic and intervention processes…

This article examines how psychometric models based on certain assumptions have come to be used counterproductively by many practitioners in ways that limit the kinds of conclusions that can be made. The general problem of the context's influence on performance is discussed, and some implications are drawn. (SLD)

This paper considers alternative assessment, feedback and cybernetics. For more than 30 years, debates about the bi-polarity of formative and summative assessment have served as surrogates for discussions about the workings of the mind, the social implications of assessment and, as important, the role of instruction in the advancement of learning.…

People can use a variety of different strategies to perform tasks and these strategies all have two characteristics in common. First, they can be evaluated in comparison with either an absolute or a relative standard. Second, they can be used at varying levels of consistency. In the present article, the authors develop a general theory of task…

Traditionally, error in equating observed scores on two versions of a test is defined as the difference between the transformations that equate the quantiles of their distributions in the sample and population of test takers. But it is argued that if the goal of equating is to adjust the scores of test takers on one version of the test to make…
