Paper Abstract:
|
The study compared the aberrance detections of a new couple of person-fit indices (W&B) with other Group-based indices (SCI, MCI, NCI, and Wc&Bs) and IRT- based indices (OUTFITz, INFITz, ECI2z, ECI4z, and lz). Four kinds of comparative conditions, including content category (CC), types of aberrance (AT), severity of aberrance (AS), and the ratios of aberrant person (AP), were implemented under the tolerance of a .05 false positive rate. Results showed that Group-based indices performed better than IRT-based indices. The WC&BS were the best, while the W&B performed as well as SCI and MCI did and exhibited nice detection rates. All indices seemed to be condition-based. For primary interest, the new developed couple indices, by having their cutoffs objectively created and revealing high power of aberrance detection, were recommended in class when students aberrant responses were diagnosed. |
