We introduce a test of economic competence for German-speaking secondary school students and provide evidence from a large-scale assessment with 6,230 students from grades seven to ten. The article presents the development and psychometric properties of the scale, as well as an investigation of...

In diesem Beitrag stelle ich Ergebnisse aus einer explorativen Studie vor, in der das Finanzwissen von Studierenden und die Rolle zentraler Agenten der finanziellen Sozialisation untersucht wurden. In der Studie wurde eine adaptierte Version einer Skala des objektiven Finanzwissens verwendet. In...

We employ a psychometrically validated performance test to study economic competence among a large and representative sample of early secondary school students in Southwest Germany. The rich dataset allows us to study variation in economic competence across school types and observable student...

Polytomous Item Response Theory Models provides a unified, comprehensive introduction to the range of polytomous models available within item response theory (IRT). It begins by outlining the primary structural distinction between the two major types of polytomous IRT models. This focuses on the...

Broadening the term augmented testing to include a combination of multiple measures to assess examinee performance on a single construct, the issues of IRT item parameter and proficiency estimates were investigated. The intent of this dissertation is to determine if different IRT calibration...

As item response theory (IRT) has developed and is widely applied, investigating the fit of a parametric model becomes an important part of the measurement process when implementing IRT. The usefulness and successes of IRT applications rely heavily on the extent to which the model reflects the...

Three decision consistency and accuracy (DC/DA) methods, the Livingston and Lewis (LL) method, LEE method, and the Hambleton and Han (HH) method, were evaluated. The purposes of the study were (1) to evaluate the accuracy and robustness of these methods, especially when their assumptions were...

A Monte Carlo simulation study investigated the effect of scoring format, item parameterization, threshold configuration, and prior ability distribution on the accuracy of ability estimation given various IRT models. Item response data on 30 items from 1,000 examinees was simulated using known...

The problem with which this study is concerned is articulating all possible CT3 and KR21 reliability measures for every case of a 5x5 binary matrix (32,996,500 possible matrices). The study has three purposes. The first purpose is to calculate CT3 for every matrix and compare the results to the...

Although the Bock–Aitkin likelihood-based estimation method for factor analysis of dichotomous item response data has important advantages over classical analysis of item tetrachoric correlations, a serious limitation of the method is its reliance on fixed-point Gauss-Hermite (G-H) quadrature...
