The research on test equating is very important for test equity , item banking , teaching quality assessing , and computerized adaptive test 等值的研究對于考試的公平性、題庫建設(shè)、教學(xué)質(zhì)量評價和計算機化自適應(yīng)測驗具有重要的意義。
Computerized adaptive testing ( cat ) , which is come forth not long ago and is still developing , is comparatively supported by items response theory 計算機化自適應(yīng)考試( computerizedadaptivetesting , cat )基于項目反應(yīng)理論,是一種方興未艾的考試形式。
In computerized adaptive testing ( cat ) , tests are automatically tailored to the proficiency level of the individual examinees , and the testing result is independent of examination items . cat can measure the real capacities of the examinees more exactly , more impersonality , and reduce the number of questions and shorten the test without affecting the reliability of the test 計算機化自適應(yīng)測試能針對不同考生的特質(zhì)水平進(jìn)行因人施考,且測試結(jié)果與樣本的選擇無關(guān);它能更準(zhǔn)確、客觀地反映考生的實際能力水平,測試周期更短而不影響測試的可靠性,是今后主流的測試類型。
With the development of educational measurement theory and computer network technology , there are some underlying changes in educational examination system in china , from traditional fixed testing based on classical test theory ( ctt ) to computerized adaptive testing ( cat ) based on item response theory ( irt ) 隨著教育測量理論和計算機網(wǎng)絡(luò)技術(shù)的發(fā)展,中國的教育考試也正在發(fā)生著悄悄的變化,由傳統(tǒng)的基于經(jīng)典測驗理論( ctt )的固定題目、同一試卷的考試向基于項目反應(yīng)理論( irt )的計算機化自適應(yīng)測試( cat )的方向轉(zhuǎn)軌。
Computerized adaptive testing (CAT) is a form of computer-based test that adapts to the examinee's ability level. For this reason, it has also been called tailored testing.
