Item Response Times in Computerized Adaptive Testing
Computerized adaptive testing (CAT) provides a score as well as item response times. However, the investigation of what additional meaning may result from response time information is of particular interest. Data from 5,912 young men on a computerized adaptive test were available. Earlier studies indicate longer response times for wrong responses. This was replicated in larger settings. However...
متن کاملOn the complementarity of classical test theory and item response models: item difficulty estimates and computerized adaptive testing
This study aims to provide statistical evidence of the complementarity between classical test theory and item response models for certain educational assessment purposes. Such complementarity might support, at a reduced cost, future development of innovative procedures for item calibration in adaptive testing. Classical test theory and the generalized partial credit model are applied to tests c...
متن کاملEstimation of a four-parameter item response theory model.
We explore the justification and formulation of a four-parameter item response theory model (4PM) and employ a Bayesian approach to recover successfully parameter estimates for items and respondents. For data generated using a 4PM item response model, overall fit is improved when using the 4PM rather than the 3PM or the 2PM. Furthermore, although estimated trait scores under the various models ...
متن کاملValidity of the three parameter item response theory model for eld test data ITP Research Series
Item response theory is a large sample procedure to estimate item parameters based on individual response strings. However, what happens when the data available to estimate item parameters is small? This situation is common when new assessment items are tried out for inclusion in future operational assessments, commonly called field testing. In field tests, many items are spread out over a fixe...
متن کاملImproving patient reported outcomes using item response theory and computerized adaptive testing.
OBJECTIVE Patient reported outcomes (PRO) are considered central outcome measures for both clinical trials and observational studies in rheumatology. More sophisticated statistical models, including item response theory (IRT) and computerized adaptive testing (CAT), will enable critical evaluation and reconstruction of currently utilized PRO instruments to improve measurement precision while re...
