Towards Efficient Item Calibration in Adaptive Testing
Reliable student models are vital for the correct functioning of Intelligent Tutoring Systems. This means that diagnosis tools used to update the student models must be also reliable. Through adaptive testing, student knowledge can be inferred. The tests are based on a psychometric theory, the Item Response Theory. In this theory, each question has a function assigned that is essential for dete...
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 کاملItem 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 کاملItem calibration in incomplete testing designs
This study discusses the justifiability of item parameter estimation in incomplete testing designs in item response theory. Marginal maximum likelihood (MML) as well as conditional maximum likelihood (CML) procedures are considered in three commonly used incomplete designs: random incomplete, multistage testing and targeted testing designs. Mislevy and Sheenan (1989) have shown that in incomple...
