    The Effect of Test Speededness Control Within A Computerized Adaptive Multi-Stage Framework
    (2019-03) Wang, Qinjun
    This dissertation examined the overall effects of test speededness control within a computer adaptive multistage (MST) framework. Although the multistage testing framework has become increasingly popular in the testing industry due to its administration efficiency as compared to traditional paper-pencil tests and its quality-control features over item level computerized adaptive testing (CAT), the paucity of research on the effect of the MST routing adaptation on examinees’ performance has hampered attempts to fully fulfill the potential of the MST framework. Considering the real time influence of the routing adaptation on examinees who receive negative feedback on their responses, these low ability examinees are more likely to experience a speeded test administration compared to their high ability counterparts. This study proposed a panel configuration design that controls the test speededness level by adding parallel modules in the test via the test assembly phase. By varying both item pool characteristics and MST configuration characteristics, the results from this study showed that the proposed speededness control panel configuration produces significantly better ability estimation compared to traditional MST designs without considering test speededness.
