Regelgeleitete Itementwicklung

Regelgeleitete Itementwicklung für mathematische Textaufgaben auf der Basis linear-logistischer Testmodelle für Itemcloning und optimaler Versuchsplanung (Holling / van der Linden; 2007-2009)

Kurzbeschreibung

Laufzeit: 2007-2009

 

In this project, techniques from cognitive analysis, item response theory (IRT), hierarchical modelling, and optimal design theory are combined to develop procedures for automated item generation and test assembly for the testing of basic mathematical competencies in early secondary education, as can be assessed with algebra word problems. It will also be investigated how the models and procedures should be optimized and generalized when they are applied in computerized adaptive testing, testing for diagnosis, and large-scale educational assessments. The final goal is the development of a software program which adaptively generates tailor-made items for algebra word problems based on optimal design, linear-logistic test models, and models for test item cloning. This program will allow for a detailed mapping of information processing in algebra word problems and will be made available to teachers for diagnostic purposes.


Forschungsstand 2009

The main goal of this project is to combine techniques from cognitive analysis, item response modeling, and optimal design theory to develop procedures for rule-based item generation and automated test assembly. The area of application is testing of statistical knowledge using word problems. During the first two years of this project a hierarchical response model for families of test items generated using cognitive rules was developed and made statistically tractable. The results were published in one manuscript for an international journal article and one book chapter. In addition, 14 cognitive rules for the generation of statistical word problems were developed and used to generate items. The rules and items were tested extensively in five different field studies. The results were published in two manuscripts for international journal articles. Further, a functional design for the automated item generator was drafted and a prototype for a text generator system developed. Finally, work on the application of optimal design theory to the automated assembly of tests from rule-based items pools has begun and its use in real-world environments has been explored. The results have been published in two manuscripts for international journal articles.
