Assessing IRT Model-Data Fit for Mixed Format Tests

This study examined various model combinations and calibration procedures for mixed format tests under different item response theory (IRT) models and calibration methods. Using real data sets that consist of both dichotomous and polytomous items, nine possibly applicable IRT model mixtures and two calibration procedures were compared based on traditional and alternative goodnessof-fit statisti...

Selecting the Best Fit Model in Cognitive Diagnostic Assessment: Differential Item Functioning Detection in the Reading Comprehension of the PhD Nationwide Admission Test

This study was an attemptto provide detailed information of the strengths and weaknesses of test takers‟ real ability through cognitive diagnostic assessment, and to detect differential item functioning in each test item. The rationale for using CDA was that it estimates an item‟s discrimination power, whereas clas- sical test theory or item response theory depicts between rather within item mu...
