Research topics
The NEPS-TBT work package, integrated into the Centre for Technology Based Assessment (TBA) at DIPF, addresses amongst others the following psychometric/diagnostic research topics:
- Test administration effects (mode effects) and test equivalence focusing on competence assessment (see also Mode Effect Study)
- (unstandardized) online testing and test setting effects (e.g. regarding motivation for working on test, e.g. Kroehne, Gnambs & Goldhammer, 2018)
- Increase of measurement efficiency, automated test assembly as well as unidimensional / multi-dimensional adaptive testing (see also the projects CaTS, PortableCAT and the software MATE)
- Innovative item and response formats for computer-based testing (complex items, see also project CavE-ICT; Engelhardt, Goldhammer, Naumann, & Frey, 2017; Engelhardt, Naumann, Goldhammer, Frey, Wenzel, Hartig, & Horz, accepted)
- Assessment and psychometric modelling of response times in computer-based tests (e.g. Goldhammer & Kroehne, 2014) and questionnaires (e.g. Kroehne & Goldhammer, 2018)
- Assessment, modelling and analysis of log and process data (see also projects Profan, ZIB priMA and MultiTex), and paradata (e.g. taxonomy in Kroehne & Goldhammer, 2018)
At the interdisciplinary Centre for Technology Based Assessment (TBA), research topics from the fields of computer science and information science are moreover focused:
- Measurement of reaction times and analysis of time accuracy of assessment systems (e.g. by means of a response time keyboard developed by TBA)
- Mobile assessment and online assessment on heterogeneous hardware
- Long-term storage of computer-based test instruments (particularly regarding task generation with CBA ItemBuilder)
- Test safety and test delivery on available hardware for computer-based testing in institutional contexts (school infrastructure)
workflow support for implementing computer-based tasks - Dissemination of log and process data
