Non-Linear Transformation of IRT Scale To Account for the Effect of Non-Normal Ability Distribution of the Item Parameter Estimation.

Yamamoto, Kentaro; Muraki, Eiji – 1991

The extent to which properties of the ability scale and the form of the latent trait distribution influence the estimated item parameters of item response theory (IRT) was investigated using real and simulated data. Simulated data included 5,000 ability values randomly drawn from the standard normal distribution. Real data included the results for…

A Latent Trait Model for Interpreting Misconceptions in Procedural Domains.

Tatsuoka, Kikumi K. – 1982

This study introduced a probabilistic model utilizing item response theory (IRT) for dealing with a variety of misconceptions. The model can be used for evaluating the transition behavior of error types, advancement of learning stages, or the stability and persistence of particular misconceptions. Moreover, it apparently can be used for relating…
