Assessment instruments that generate quantitative data on attributes (cognitive, affective, behavioral, "etc.") of participants are commonly used in the chemistry education community to draw conclusions in research studies or inform practice. Recently, articles and editorials have stressed the importance of providing evidence for the…

In this study, we propose that the unique needs and characteristics of linguistic minorities should be considered throughout the test development process. Unlike most measurement invariance investigations in the assessment of linguistic minorities, which typically are conducted after test administration, we propose strategies that focus on the…

Energy is a core concept in the teaching of science. Therefore, it is important to know how students' thinking about energy develops so that elementary, middle, and high school students can be appropriately supported in their understanding of energy. This study tests the validity of a proposed theoretical model of students' growth of understanding…

Starting from an explicit scoring rule for time limit tasks incorporating both response time and accuracy, and a definite trade-off between speed and accuracy, a response model is derived. Since the scoring rule is interpreted as a sufficient statistic, the model belongs to the exponential family. The various marginal and conditional distributions…

The paper develops a two-stage robust procedure for structural equation modeling (SEM) and an R package "rsem" to facilitate the use of the procedure by applied researchers. In the first stage, M-estimates of the saturated mean vector and covariance matrix of all variables are obtained. Those corresponding to the substantive variables…

After many equatings have been conducted in a testing program, equating errors can accumulate to a degree that is not negligible compared to the standard error of measurement. In this paper, the author investigates the asymptotic accumulative standard error of equating (ASEE) for linear equating methods, including chained linear, Tucker, and…

Though calibration of an achievement test within psychological and educational context is very often carried out by the Rasch model, data sampling is hardly designed according to statistical foundations. However, Kubinger, Rasch, and Yanagida (2009) recently suggested an approach for the determination of sample size according to a given Type I and…

The objective of this study was to provide empirical evidence to support psychometric properties of a modified four-dimensional model of the Leadership Scale for Sports (LSS). The study tested invariance of all parameters (i.e., factor loadings, error variances, and factor variances-covariances) in the four-dimensional measurement model between…

The Inviting School Survey-Revised (ISS-R) was adapted and translated into Traditional Chinese (ISS-RC), using a five-step process, based on international test administration guidelines, involving judgmental, logical, and empirical methods. Both versions were administered to a convenience sample of Chinese-English fluent Hong Kong school community…

After a brief review of recent advances in sequential analysis involving sequential generalized likelihood ratio tests, we discuss their use in psychometric testing and extend the asymptotic optimality theory of these sequential tests to the case of sequentially generated experiments, of particular interest in computerized adaptive testing. We…

This investigation reports on the cross-cultural equivalence testing of the Self-Description Questionnaire II (short version; SDQII-S) for Indigenous and non-Indigenous Australian secondary student samples. A variety of statistical analysis techniques were employed to assess the psychometric properties of the SDQII-S for both the Indigenous and…

We introduce a family of goodness-of-fit statistics for testing composite null hypotheses in multidimensional contingency tables. These statistics are quadratic forms in marginal residuals up to order "r." They are asymptotically chi-square under the null hypothesis when parameters are estimated using any asymptotically normal consistent…

The article examines changes in language testing textbooks in English since Lado (1961) and proposes that two trends may be discerned. The first shows how the growing professionalism of the field has required an expansion in teaching materials to meet the need for new training programmes. What the expansion also shows is the desire, again a mark…

By comparing the profile of "g" loadings for a set of psychometric test scores, it is shown that general intelligence is related to timed performance measures from perceptual-motor tasks, more strongly on more complex tasks. The profile of the "g" loadings was predictable from the response-time (RT) psychometric test time correlations for four RT…

A pattern-analytical technique, Similar Response Analysis (SRA), was developed, validated with contrived data, verified using previously reported data based on other pattern-analytical methods, and used successfully with "real" data. This technique orders subjects on the basis of the similarity of responses of adjacent individuals, not…
