This study explored the applicability of the Test of Creative Thinking-Drawing Production (TCT-DP) in the Hong Kong Chinese cultural context. The psychometric properties of scores on the TCT-DP were examined in a sample of 2,368 Hong Kong Chinese students aged 12 to 16. The study compared the TCT-DP's internal consistency, interrater, and…

We make theoretical comparisons among five coefficients--Cronbach's [alpha], Revelle's [beta], McDonald's [omega][sub h], and two alternative conceptualizations of reliability. Though many end users and psychometricians alike may not distinguish among these five coefficients, we demonstrate formally their nonequivalence. Specifically, whereas…

In the signal detection paradigm, the non-parametric index of sensitivity A', as first introduced by Pollack and Norman (1964), is a popular alternative to the more traditional d' measure of sensitivity. Smith (1995) clarified a confusion about the interpretation of A' in relation to the area beneath proper receiver operating characteristic (ROC)…

The purpose of this note is twofold: (a) to present the formula for the item information function (IIF) in any direction for the Multidimensional 3-Parameter Logistic (M3-PL) model and (b) to give the equation for the location of maximum item information (theta[sub max]) in the direction of the item discrimination vector. Several corollaries are…

This paper updates the research literature on the Student Leadership Practices Inventory, which is one of the few leadership development instruments targeted for college students. The psychometric properties of a revised version of the instrument are also provided, along with a discussion of developmental issues pertinent to developing and…

Relatively little is known about students' conceptions of research and, in particular, whether there are conceptually discrete patterns of variation that can be used to model this phenomenon in terms of research-as-learning outcomes. The present study explores the dimensionality of students' conceptions of research from two complementary research…

Increasing numbers of children with autism spectrum disorder (ASD) are diagnosed in the preschool years, and their educational progress must be monitored. Parent questionnaire data can augment psychometric assessments and individual planning at low cost. One hundred and twenty-five parents of UK children who entered dedicated autism primary…

This article presents relevant research on Bayesian methods and their major applications to modeling in an effort to lay out differences between the frequentist and Bayesian paradigms and to look at the practical implications of these differences. Before research is reviewed, basic tenets and methods of the Bayesian approach to modeling are…

This article explores the tensions between Howard Gardner's theory of multiple intelligences and current educational policies emphasizing standardized and predictable outcomes. The article situates Gardner's theory within the historical interests among psychometricians in identifying those core processes that constitute human intelligence.…

By regarding the latent random vectors as hypothetical missing data and based on the conditional expectation of the complete-data log-likelihood function in the EM algorithm, we investigate assessment of local influence of various perturbation schemes in a nonlinear structural equation model. The basic building blocks of local influence analysis…

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. I argue that there are many questions about RTI that remain unanswered, and radical changes in proposed regulations are not warranted at this time. Many fundamental issues related to RTI…

The Candecomp/Parafac (CP) model decomposes a three-way array into a prespecified number R of rank-1 arrays and a residual array, in which the sum of squares of the residual array is minimized. The practical use of CP is sometimes complicated by the occurrence of so-called degenerate solutions, in which some components are highly correlated in all…

The purpose of this study was to develop a test of academic readiness for first grade instruction in Thailand. Test of Academic Readiness (TAR) consists of six domains: verbal, visual, memory, math, logical, and general knowledge. Two pilot studies were carried out and a main study tested items in those domains. Rasch model was used to assess the…

Qatar has recently positioned itself to be a leader in education. Central to the country's efforts is the implementation of reforms to its K-12 education system. Central to the reform initiatives was the development of internationally benchmarked curriculum standards in four subjects: Arabic, English as a foreign language, mathematics, and…

Although the Angoff procedure is among the most widely used standard setting procedures for tests comprising multiple-choice items, research has shown that subject matter experts have considerable difficulty accurately making the required judgments in the absence of examinee performance data. Some authors have viewed the need to provide…
