Peng Wang, Xinli Zhu, Fang Wang · 2015
Multidimensional Item Response Theory (MIRT) is the new development of modern psychometric theories. The psychometric models, parameter estimation and application of MIRT are over- viewed in this paper. It is concluded that the development of MIRT models should be combined with cognitive construct, the method of MCMC should be used to enhance the parameter estima- tion of MIRT, the research of the mixed MIRT should be strengthened, and the method of maxi- mum information should be used to get the total score of a test.
