Studied two procedures for detecting potentially flawed items in translated tests with small samples: (1) conditional item "p" value comparisons; and (2) delta plots. Varied several factors in this simulation study. Findings show that the two procedures can be valuable in identifying flawed test items, especially when the size of the…

Examined the polytomous differential functioning of items and tests (DFIT) framework proposed by N. Raju and others through simulation. Findings show that the DFIT framework is effective in identifying differential item functioning and differential test functioning. (SLD)

Conducted a regression analysis to assess the contributions of passage and no-passage factors to item variance on the Scholastic Aptitude Test reading comprehension task. Results show that no-passage factors play a larger role than do passage factors, accounting for as much as three-fourths of systematic variance in item difficulty and more than…

Examined the use of the generalized graded unfolding model (GGUM) in computerized adaptive testing, using simulation and attempting to minimize the number of items required to produce equiprecise estimates of person locations. Results suggest that adaptive testing with the GGUM is a good method for achieving estimates with an approximately uniform…

In this article, the author describes how she and her eighth-grade class moved away from formalism into a more personal, more connected, more authentic response to literature. She also explains the importance of a transactional approach in teaching literature and creating a democratic classroom. She honors Louise Rosenblatt, who introduced…

This article reviews the empirical literature on 9 topics about the modified Angoff standard-setting method that have been studied repeatedly in the literature, while taking into consideration the methodological warrant for the findings on the topics. It concludes that we can be reasonably confident about selecting the appropriate number of judges…

Winsteps (Rasch Measurement Software and Publications, 2003), as its name implies, is a psychometric program created specifically to compute the step function (Wright & Masters, 1982) for exams carrying partial-credit items. Despite the clarity of the Rasch model (Bond & Fox, 2001) and the availability of rich features in the program, such as the…

One approach to measuring unsigned differential test functioning is to estimate the variance of the differential item functioning (DIF) effect across the items of the test. This article proposes two estimators of the DIF effect variance for tests containing dichotomous and polytomous items. The proposed estimators are direct extensions of the…

This technical report and user's guide is designed to provide researchers with an overview of the design and implementation of the 2009 Program for International Student Assessment (PISA), as well as with information on how to access the PISA 2009 data. This information is meant to supplement that presented in Organization for Economic Cooperation…

The main aim of this article is to explicate why a transition to ideal point methods of scale construction is needed to advance the field of personality assessment. The study empirically demonstrated the substantive benefits of ideal point methodology as compared with the dominance framework underlying traditional methods of scale construction.…

This paper draws on data from the development of annual national mathematics assessment materials for 7-year-old pupils in Wales for use during the period 2000-2002. The materials were developed in both English and Welsh and were designed to be matched. The paper reports on item analyses which sought items that exhibited differential performance…

The recent positions of the Association to Advance Collegiate Schools of Business (AACSB) and the European Foundation for Management Developments (EQUIS) on the value of entrepreneurship suggest a more entrepreneurial perspective in a business school's culture and strategic processes for obtaining and sustaining a business school's reputation. The…

The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological…

Because of the increased popularity of computerized adaptive testing (CAT), many admissions tests, as well as certification and licensure examinations, have been transformed from their paper-and-pencil versions to computerized adaptive versions. A major difference between paper-and-pencil tests and CAT from an examinee's point of view is that in…

Two conditional versions of the exposure-control method with item-ineligibility constraints for adaptive testing in van der Linden and Veldkamp (2004) are presented. The first version is for unconstrained item selection, the second for item selection with content constraints imposed by the shadow-test approach. In both versions, the exposure rates…
