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 ...

This doctoral thesis scrutinizes the content dimension of the Trends in International Mathematics and Science Study (TIMSS) to explore: “What content-specific profiles can we obtain about the students’ strengths and ...

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 ...

The Openness-Fluid-Crystallized-Intelligence (OFCI) model describes how these different constructs interact over time. One fundamental element in the model is the Environmental Enrichment Hypothesis, which states that more ...

This study aims at modeling the self-reported test-taking motivation items in PISA and TIMSS Advanced studies for Swedish students using an IRT approach. In the last two cycles of the assessments, six test-specific items ...

It is currently not entirely clear to what degree the research on multidimensional computerized adaptive testing (CAT) conducted in the field of educational testing can be generalized to fields such as health assessment, ...

Die Fähigkeit, mathematische Inhalte in Spielsituationen der Kindertagesstätte zu identifizieren, um diese für eine angemessene Förderung mathematischer Kompetenzen bei Kindern zu nutzen, kann als ein wesentlicher Bestandteil ...

How teacher characteristics are related to student outcomes may indicate ways to improve the effectiveness of schooling. This paper examines how consistent such relations are by utilizing TIMSS data on five teacher ...

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, ...
