The goal of this study was to investigate sources of evidence of convergent validity supporting the construct interpretation of scores on a simulation-based information and communication technology (ICT) skills test. The ...

Item context effects refer to the impact of features of a test on an examinee's item responses. These effects cannot be explained by the abilities measured by the test. Investigations typically focus on only a single type ...

Although multidimensional adaptive testing (MAT) has been proven to be highly advantageous with regard to measurement efficiency when several highly correlated dimensions are measured, there are few operational assessments ...

Computer-based assessments open up new possibilities to measure constructs in authentic settings. They are especially promising to measure 21st century skills, as for instance information and communication technologies ...

In computerized adaptive testing (CAT), item parameter estimates are assumed to be known and valid for all the positions that items can be presented on in the test. This assumption is problematic since item parameter ...

A new response time-based method for coding omitted item responses in computer-based testing is introduced and illustrated with empirical data. The new method is derived from the theory of missing data problems of Rubin ...

Accurate item calibration in models of item response theory (IRT) requires rather large samples. For instance, [Formula: see text] respondents are typically recommended for the two-parameter logistic (2PL) model. Hence, ...

Background The Faces Pain Scale-revised (FPS-r) has been developed as an interval scale. For other pain measurement instruments, several studies found evidence for and against an interval level of measurement. Object ...

Position effects (PE) cause decreasing probabilities of correct item responses towards the end of a test. We analysed PEs in science, mathematics and reading tests administered in the German extension to the PISA 2006 study ...

The increasing digitalization in the field of psychological and educational testing opens up new opportunities to innovate assessments in many respects (e.g., new item formats, flexible test assembly, efficient data ...
