Comparing Parametersof Many Facetrasch Measurement Model And Hierarchial Rater Model
Abstract
This study aims at estimating the parameters with many facet Rasch measurement model (MFRMM) and hierarchical rater model (HRM) and evaluating together the rater severty/leniency and parameters obtained from both models if responses given by the same examinees for open-ended items are scored by multiple raters. In the scope of collecting study data, the scores assigned by five secondary school mathematics teachers for responses to eight open-ended items by 380 students, aged 15, from 10 schools in Çankaya District of Ankara province were used during the 2nd semester of the 2012-2013 academic year. The study revealed that rater parameters of MFRMM and HRM were similar in general. According to the deviation in formation criteria for both models; it was concluded that HRM provides better fit the data than MFRMM and the structure of assigned multiple scores regarding one single response to one single item is reflected beter by the HRM.
