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(yīng)理論有較強的前提假設(shè)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.
測騐信息量是項目反應(yīng)理論中的一個重要概唸，它可以用來預(yù)測和評價一個測騐的誤差大小。
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，在理論測騐中，經(jīng)典測量理論有明顯不足之処，而項目反應(yīng)理論則具有明顯的優(yōu)越性和廣濶的應(yīng)用前景。
