TY - JOUR ID - 1374950 AU - Hübnerová, Zuzana - Váňová, Tamara - Procházka, Jiří PY - 2013 TI - Estimates of item parameters in computer adaptive testing PB - Brno University of Technology CY - Brno SN - 9788021447554 KW - Benchmarking KW - Computer adaptive placement test KW - IRT KW - Parameter estimate N2 - This paper focuses on the problems connected with estimating parameters in a computer adaptive online language test developed at Masaryk University and used as a prerequisite for hundreds of students every semester before their enrolment in seminars of English for Special Purposes or Academic English. A segment estimate of parameters of the item response function is suggested as a solution of the so-called guessing problem. The results are compared with the usual approach, namely applying a three-parameter model. ER -
