Explored the measurement issues in a two-stage evaluation for an outstanding faculty award. Thirty college teachers were rated by 293 students using a newly developed inventory. Items fit a Rasch model fairly well, and the separation reliability for the teachers was high. A cut score was established, and a short version was developed. (SLD)

Wang, Wen-Chung – Journal of Applied Measurement, 2000
Proposes a factorial procedure for investigating differential distractor functioning in multiple choice items that models each distractor with a distinct distractibility parameter. Results of a simulation study show that the parameters of the proposed modeling were recovered very well. Analysis of 10 4-choice items from a college entrance…

Wang, Wen-Chung – Journal of Applied Measurement, 2000
Extended conventional two-group differential item function (DIF) analysis for dichotomous items to factorial DIF analysis for polytomous items where multiple grouping factors with multiple groups in each are analyzed jointly. Simulation studies and analysis of a real data set with 1,924 subjects show the parameters of the proposed modeling can be…
