Online Item Calibration for Q-matrix in CD-CAT
Item replenishment is important to maintaining a large scale item bank. In this paper we consider calibrating new items based on pre-calibrated operational items under the DINA model, the specification of which includes the so-called Q-matrix, as well as the slipping and guessing parameters. Making use of the maximum likelihood and Bayesian estimators for the latent knowledge states, we propose...
متن کاملUsing Automatic Item Generation to Address Item Demands for CAT
Item writing is a craft that is both resource intensive and time consuming. In order to minimize item exposure, computer adaptive testing requires a large number of test items for administration. As test development become more complex, demand for the quantity and quality of items far exceeds the capacity of item writers writing in the current fashion. To address the demand for items to be crea...
متن کاملNew Methods of Online Calibration for Item Bank Replenishment by Yi Zheng Dissertation
Item parameter calibration is important for tests based on item response theory, because the scoring, equating, bias analysis of the test, and item selection in adaptive tests are all based on the item parameters. As a test is continuously administered, item calibration needs to be conducted for new items at intervals to replace overexposed, obsolete, or flawed items in the item bank. Although ...

15 صفحه اولEffect of item order on item calibration and item bank construction for computer adaptive tests
Item banks are typically constructed from responses to items that are presented in one fixed order; therefore, order effects between subsequent items may violate the independence assumption. We investigated the effect of item order on item bank construction, item calibration, and ability estimation. 15 polytomous items similar to items used in a pilot version of a computer adaptive test for anx...
