Analysis of Measurement Instruments: Introduction to classical test theory, item response models and multilevel item response models Twente University Dates: 16 – 19 December 2014 Target The course provides an introduction on classical and modern test theory and its major applications, such as the construction of measurement instruments, linking and equating measurements, evaluation differential item functioning, optimal test construction, computerized adaptive testing and the evaluation of large-scale educational surveys such as PISA and TIMSS. The introduction is broad and on a conceptual level, but references will be provided to the more technical aspects such as estimation and testing of the models. The second part of the course will focus on Bayesian item response modeling. An introduction will be given to the important features of the Bayesian modeling approach, which will be illustrated with real data examples using software packages OpenBugs and R. The practicals will focus on standard software, but interested students will also be given the opportunity to get acquainted with Bayesian modeling software.
