Multidimensional Computerized Adaptive Testing Based on Bayesian Theory
Effective and efficient assessment of a learner’s proficiency has always been a high priority for intelligent e-Learning environments. The fields of psychometrics and Computer Adaptive Testing (CAT) provide a strong theoretical and practical basis for performing skills assessment, of which Item Response Theory (IRT) is the best recognized approach. For assessing multiple skills at once, which i...
متن کاملThe Nominal Response Model in Computerized Adaptive Testing
One important and promising application of item response theory (IRT) is computerized adaptive testing (CAT). The implementation of a nominal response model-based CAT (NRCAT) was studied. Item pool characteristics for the NRCAT as well as the comparative performance of the NRCAT and a CAT based on the three-parameter logistic (3PL) model were examined. Ability estimates were generated at test l...
متن کاملFinite Element Simulation and ANFIS Prediction of Dimensional Error Effect on distribution of BPP/GDL Contact Pressure in PEM Fuel Cell
Distribution of contact pressure between the bipolar plate and gas diffusion layer considerably affect the performance of proton exchange membrane fuel cell. In this regard, an adaptive neuro-fuzzy inference system (ANFIS) is developed to predict the contact pressure distribution on the gas diffusion layer due to dimensional errors of the bipolar plate ribs in a proton exchange membrane fuel ce...
متن کاملComputerized Adaptive Testing in Instructional Settings
Item response theory (IRT) has most often been used in research on computerized adaptive testing (CAT). Depending on the model used, IRT requires between 200 and 1,000 examinees for estimating item parameters. Thus, it is not practical for instructional designers to develop their own CAT based on the IRT model. Frick improved Wald" s sequential probability ratio test (SPRT) by combining it with...
متن کاملInvestigating the Impact of Item Parameter Drift for Item Response Theory Models with Mixture Distributions
This study investigates the impact of item parameter drift (IPD) on parameter and ability estimation when the underlying measurement model fits a mixture distribution, thereby violating the item invariance property of unidimensional item response theory (IRT) models. An empirical study was conducted to demonstrate the occurrence of both IPD and an underlying mixture distribution using real-worl...
