A critical review of the Expressive One-Word Picture Vocabulary Test (Gardner) is offered. The reviewer feels that the instrument cannot be recommended in its present form. Further research concerning the manual, and theoretical issues, (particularly test-retest stability) is strongly recommended. (Author/PN)

Reviews a number of issues relating to the results of evaluation studies: standards of acceptability; clinical vs. statistical significance; fallacies in the use of theory; and program, theory, measurement, and design failure. (Journal availability: Subscription Manager, MOBIUS, University of California Press, Berkeley, CA 94720.) (SK)

Even in an educational tests and measurements classroom it is possible to stimulate student creativity and divergent thinking. Examples of projects and test constructions are given to provide food for thought for the creative teacher. (JN)

Illustrates the utility of nonreactive measures with preschool children in a variety of contexts. Offers a rationale for using nonreactive and observational tests and interview measures. Discusses four types of nonreactive measures and their limitations. (Author/BB)

The conflict between immediacy and accuracy in data-gathering and analysis is discussed. The case of the Postsecondary Transcript Sample (PETS) of the National Longitudinal Study is used to illustrate the particulars of this conflict and their resolution on the side of accuracy. (Author/MLW)

A procedure is described for estimating the reliability and conditional standard errors of measurement of scale scores incorporating the discrete transformation of raw scores to scale scores. The method is illustrated using a strong true score model, and practical applications are described. (SLD)

Effects of dimensionality on ability estimation of an adaptive test were examined using generated data in Bayesian computerized adaptive testing (CAT) simulations. Generally, increasing interdimensional difficulty association produced a slight decrease in test length and an increase in accuracy of ability estimation as assessed by root mean square…

Drawing from the Technology Acceptance Model, this correlational study was intended to determine student users' adoption of WebCT and its relationship to their final grade. In acknowledging the relevance of human-computer interaction, the author attempted to investigate a belief-attitude-behavior relationship in a WebCT setting. Given a social…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

Oral retellings are strongly recommended as a way to measure reading comprehension for second language learners (Bernhardt, 1985, 1990, 1991). However, the reliability of such ratings is a matter of concern for a variety of reasons (Aiken, 1996; Cooper, 1981; Saal, Downey, & Lahey, 1980). The purpose of this study was to establish reliable rating…

Background: Influential studies have cast doubt on the validity of retrospective reports by adults of their own adverse experiences in childhood. Accordingly, many researchers view retrospective reports with scepticism. Method: A computer-based search, supplemented by hand searches, was used to identify studies reported between 1980 and 2001 in…

General self-efficacy (GSE), individuals' belief in their ability to perform well in a variety of situations, has been the subject of increasing research attention. However, the psychometric properties (e.g., reliability, validity) associated with the scores on GSE measures have been criticized, which has hindered efforts to further establish the…

This report provides international benchmarks to help states see how students are doing in math and science within an international context. It shows how state-by-state results from the National Assessment of Educational Progress (NAEP) can be linked with nation-by-nation results from the Trends in International Mathematics and Science Study…

Most educational measurement texts distinguish between norm-referenced (NR), or relative, methods of assigning letter grades to objective test scores, and criterion-referenced (CR), or absolute, methods. Both NR and CR approaches have serious limitations in typical classroom situations, and neither approach, in its pure form, may be entirely…

The gain, or difference, score is defined as the difference between the posttest score and the pretest score for an individual. Gain scores appear to be a natural measure of growth for education and the social sciences, but they contain two sources of measurement error, error in either the pretest or posttest scores, and cannot be considered…
