試題反應理論在教育測驗上之應用

Application of IRT in Educational Measurement

本文主要簡介試題反應理論的發展與應用，首先，比較試題反應理論與古典測驗理論之差異，接著介紹目前常用試題反應理論模式，例如：單向度單參數、二參數、三參數Logistic模式及多向度模式，進而簡介新發展之高階試題反應理論模式並舉例說明使用上之差異，最後，說明試題反應理論在大型教育測驗及電腦化適性測驗上之應用。

The goal of this paper is to introduce the development and application of item response theory. First, the differences of item response theory and classical test theory are compared. Second, some useful and poplar item response models are mentioned, such as unidimensional one-parameter, two-parameter, three-parameter logistic models and multidimenstional models. Moreover, some recently proposed higer-order item response models are also described. Final part contains the applications of item response theory to the large scale education assessments and computerized adaptive tests.
