What is Item Response Theory, IRT? A Tentative TaxonomyThomas Eckes
摘要: Item response theory (IRT) is concerned with accurate test scoring and development of test items. You design test items to measure various kinds of abilities (such as math ability), traits (such as extroversion), or behavioral characteristics (such as...
Thisreview introducesclassicalitem response theory (IRT) modelsas well as more contemporaryextensions to the case ofmultilevel,multidimensional, and mixtures of discrete and continuous latent variablesthrough the lens ofdiscretemultivariate analysis.A general modeling framework is discussed, andthe applications...

A common algorithm is isBayesian Knowledge Tracing (BKT)which estimates the rate at which learning occurs. Another known framework isItem Response Theory (IRT), developed in the field of psychometrics to model the interaction of a learner with discrete items. ...
high-profile organizations typically useitem response theory (IRT), which is based on a type of nonlinear regression analysis. Psychometricians evaluate overall reliability of the test, difficulty and discrimination of each item, distractor analysis, possible bias, multidimensionality, linking multiple tes...
It assumes that the probability of a correct or keyed response to an item is a function of the person’s ability and characteristics, such as difficulty, discrimination, and guessing. It helps developers to bank items, prepare adaptive testing, and equate test scores across different forms and ...
Depression accounts for the largest proportion of the burden associated with all the mental and neurological disorders and is a particular focus of this ... DOM Health 被引量: 78发表: 2001年 Can item response theory reduce patient burden when measuring health status in neurological disorders? Resu...
There has been increasing demand for a reliable measurement method for social cohesion for scientific analysis, but due to the difficulty in multidimensional measurement, the search is in progress. In order to tackle the problem, the paper applies the Item Response Theory approach to measure social...
