| Summary : Optimal Item Calibration
|
Description :
The restricted optimal design method is implemented to optimally
allocate a set of items that require calibration to a group of
examinees. The optimization process is based on the method described in
detail by Ul Hassan and Miller in their works published in (2019)
< doi:10.1177/0146621618824854> and (2021)
< doi:10.1016/j.csda.2021.107177>. To use the method, preliminary item
characteristics must be provided as input. These characteristics can
either be expert guesses or based on previous calibration with a small
number of examinees. The item characteristics should be described in
the form of parameters for an Item Response Theory (IRT) model. These
models can include the Rasch model, the 2-parameter logistic model, the
3-parameter logistic model, or a mixture of these models. The output
consists of a set of rules for each item that determine which examinees
should be assigned to each item. The efficiency or gain achieved
through the optimal design is quantified by comparing it to a random
allocation. This comparison allows for an assessment of how much
improvement or advantage is gained by using the optimal design
approach. This work was supported by the Swedish Research Council
(Vetenskapsrådet) Grant 2019-02706.
