title = "Playing PISA with bebras",
abstract = "To test and adopt the methodology of future PISA surveys in Computer Science, we have utilized the Bebras Contest as a test field. We performed latent trait analysis of the questions of the German Bebras contest 2009 to find sets of questions that might measure joint psychometric constructs (competencies). After having identified several sets, we have tested the fit of the mono-parametric Rasch Model and evaluated the distribution of person parameters.",
