A STUDY ON THE APPLYING OF ITEM RESPONSE MODELS
项目反应模型的应用问题研究

The study focused on the selections to mathematical models of item response theory, and fitting tests of mathematical models. relations between the sample size and item reponse models, and relations between the sample size and pararnaters estimation of item response models. All the data the study adopted came from the National College Entrance Examination. The study has come to some significant conclusions.
