An overview of differential item functioning in multistage computer adaptive testing using three-parameter logistic item response theory
As perfectly summarised by Ida Lawrence, “Testing is growing by leaps and bounds across the world. There is a realization that a nation’s well-being depends crucially on the educational achievement of its population. Valid tests are an essential tool to evaluate a nation’s educational standing and to implement efficacious educational reforms. Because tests consume time that otherwise could be d...
متن کاملIRT-FIT: SAS® Macros for Fitting Item Response Theory (IRT) Models
Psychometrics has recently seen the development of complex measurement models to better represent test and item data. Item Response Theory (IRT), in particular, comprises a set of non-linear latent variable models that appear to have several conceptual and empirical properties that make them more valuable in practice than classical test theory methods. However, IRT-based models typically requir...
متن کاملEstimating Student Proficiency Using an Item Response Theory Model
Item Response Theory (IRT) models were investigated as a tool for student modeling in an intelligent tutoring system (ITS). The models were tested using real data of high school students using the Wayang Outpost, a computer-based tutor for the mathematics portion of the Scholastic Aptitude Test (SAT). A cross-validation framework was developed and three metrics to measure prediction accuracy we...
متن کاملStudents’ proficiency scores within multitrait item response theory
In this paper we present a series of item response models of data collected using the Force Concept Inventory. The Force Concept Inventory (FCI) was designed to poll the Newtonian conception of force viewed as a multidimensional concept, that is, as a complex of distinguishable conceptual dimensions. Several previous studies have developed single-trait item response models of FCI data; however,...
متن کاملItem 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...
