Mathematical-Programming Approaches to Test Item Pool Design. Research Report.
Veldkamp, Bernard P.; van der Linden, Wim J.; Ariel, Adelaide
This paper presents an approach to item pool design that has the potential to improve on the quality of current item pools in educational and psychological testing and thus to increase both measurement precision and validity. The approach consists of the application of mathematical programming techniques to calculate optimal blueprints for item pools. These blueprints can be used to guide the item-writing process. Three different types of design problems are discussed: (1) item pools for linear tests; (2) item pools for computerized adaptive testing (CAT); and (3) systems of rotating pools for CAT. The paper concludes with an empirical example of the problem of designing a system or rotating item pools for CAT. (Contains 2 tables and 22 references.) (Author/SLD)
