Item pool design for computerized adaptive tests
Although item pools are critical to the proper functioning of computerized adaptive tests (CATs), there is very little in the research literature that indicates the desired features of an item pool. Most research articles use an existing item pool that was developed for other purposes. For example, Pastor, Dodd and Chang (2002) used items from NAEP; Wang and Kolen (2001) used an item pool from ...
متن کاملHelping Tools for Item Bank Calibration and Development of Computerized Adaptive Tests
Recently-developed testing theories and current technology make possible a fast and easy generation of computerized adaptive tests (CATs), which emulate the intelligent behaviour of human evaluators. In fact, they dynamically select and administer the most appropriate items depending on the previous responses given by the examinees. However, to choose the proper item from the bank, the CAT algo...
متن کاملEffect 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...
متن کاملApplication of Optimal Designs to Item Calibration
In computerized adaptive testing (CAT), examinees are presented with various sets of items chosen from a precalibrated item pool. Consequently, the attrition speed of the items is extremely fast, and replenishing the item pool is essential. Therefore, item calibration has become a crucial concern in maintaining item banks. In this study, a two-parameter logistic model is used. We applied optima...
متن کاملConstraining Item Exposure in Computerized Adaptive Testing with Shadow Tests
Item-exposure control in computerized adaptive testing is implemented by imposing item-ineligibility constraints on the assembly process of the shadow tests. The method resembles Sympson and Hetter's (1985) method of item-exposure control in that the decisions to impose the constraints are probabilistic. However, the method does not require time-consuming simulation studies to set values for co...
