|Estimation 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...
|I’ve Fallen and I Can’t Get Up: Can High-Ability Students Recover From Early Mistakes in CAT?
||A difficult result to interpret in Computerized Adaptive Tests (CATs) occurs when an ability estimate initially drops and then ascends continuously until the test ends, suggesting that the true ability may be higher than implied by the final estimate...
