NEPS TBT: Work Package Technology Based Testing
The working package Technology Based Testing (TBT) at NEPS belongs to the methods group of NEPS. TBT at DIPF is located within the interdisciplinary TBA (Technology Based Assessment)-group and is under the scientific direction of Prof. Frank Goldhammer. TBT closely co-operates with LIfBi and is engaged in innovative interview techniques and testing methods, for example, computer- and internet-based competency assessment.
The working package TBT supports the introduction and realisation of technology-based testing in NEPS with scientifically based services, project specific adaptations of software products and accompanying research. For the domains reading, math, science and ICT Literacy, which are tested several times in the longitudinal study of NEPS, changes concerning measurement instruments due to the computerisation are explored psychometrically based on the combined mode effect and linking studies as well as based on the help of experimental modus variation. Therefore, procedures of quantification and correction of mode effects are investigated and applied precisely that enable an introduction of computer based competency measurement in NEPS .
After successfully introducing technology based testing in the extra-institutional and institutional survey context of NEPS the scientific and development focus is on the use of characteristics of technology-based testing. This aims at the enhancement and optimisation of assessments in regard to validity (for example, simulation based assessment of ICT Literacy, e.g. TECCI or CavE-ICT Pisa) as well as the increase of measurement efficiency (see, for example, HEUREKO and MATE) and the use of log and processing data (see, for example, PROKOM).
Finished project phase 2009-2013
In the project phase 2009 until 2013, preparatory to the work package Technology Based Testing (TBT) DIPF was responsible for the following tasks:
NEPS AP 13 B
- The software development for a data warehouse has been located at TBA; the data warehouse ensures a data access as fast as possible while considering privacy data protection.
- The development of a data warehouse was supposed to guarantee a central data stock for the entire NEPS study and to provide appropriate tools for filtering as well as report production.
- Data Warehouse: Three proceeding processes of parallel software developed during the project duration: (1) implementation, optimisation and development of data banks (2) implementation, optimisation and further development of ETL- and reporting tools (3) implementation, optimisation and further development of a web portal.
- With the Data Warehouse the data from the four waves of assessment as well as the tools for filtering and report production should be accessible for the whole scientific community subsequently.
NEPS AP 13 C
- For the preparation of the electronic test assessment empirical assessments had been conveyed to identify possible differences between paper-based and computer-based testing (quantification of mode effects) and to investigate computer-based testing results (cross mode linking).
- Mode effect studies (equivalence studies combined with linking studies of NEPS) have been conducted to prepare a test execution on a technological basis. The mode effect studies aimed at testing the equivalence of paper-based assessments (PBA) and computer-based assessment (CBA) by means of different criteria. The organisation and execution of mode effect studies was carried out with pillar 1 (Competence development in the life course).
