item response theory

基本解釋

Item response theory is considered as one of the best hypothesis to detect the DIF compared with the classical measurement theory.
與經(jīng)典測量理論相比，在測查項目功能差異時，運用項目反應理論有較強的前提假設和優(yōu)越性。
The test information is an important concept in the Item Response Theory. It could be used to predict and evaluate the quality of one test.
測驗信息量是項目反應理論中的一個重要概念，它可以用來預測和評價一個測驗的誤差大小。
The results indicated that in knowledge tests classical measurement theory is obviously disadvantageous, but item response theory is advantageous and has its broad prospect in application.
結(jié)果表明，在理論測驗中，經(jīng)典測量理論有明顯不足之處，而項目反應理論則具有明顯的優(yōu)越性和廣闊的應用前景。
