Some practical item selection algorithms in cognitive diagnostic computerized adaptive testing -- smart diagnosis for smart learning
… learning over twenty years ago. Several new selection algorithms are proposed for addressing two important issues in CD-CAT: measurement efficiency and item exposure control. The posterior-weighted CDM discrimination index (PWCDI) and posterior-weighted attribute-level CDM discrimination …

Computerized Adaptive Testing---New Developments and Applications
… becomes a big concern. Large-scale on-line item theft has caused the termination of the CAT Graduate Record Exam (GRE) in several Asian countries and areas. Consequently, protecting test security becomes a crucial component of every CAT program that offers continuous testing. Chapter 2 …

Kullback-Leibler information and its applications in multidimensional adaptive testing
… information in the context of multi-dimensional item response theory and is further interpreted for the two-dimensional case, from a geometric perspective. This explication should allow for a better understanding of the various item selection methods in multi-dimensional adaptive tests (MAT) …

On-the-fly assembled multistage adaptive testing
… serious drawback of MST is that the bundling of items and modules may have security threat when it is being administered continuously and the test items are purposefully shared among examinees via internet. Research on innovative MST designs that assembled items on-the-fly have shown great …

The effectiveness of using multiple item pools to increase test security in computerized adaptive testing
… to investigate the effectiveness of a multiple item pool design verse the commonly used single pool design in terms of measurement precision, item exposure control and item pool usage balance for Computerized Adaptive Testing (CAT). Also, the extent to that multiple item pools can reduce the …

Toward Culturally Responsive and Equitable Testing: Innovative Psychometric Analyses on Contextualized Measurement and Adaptive Testing
… on cultural characteristics of contextualized items, students, and multigroup fairness from empirical and simulated datasets. The first study contributed to the understanding of culturally valid and equitable contextualized items, by implementing a coding rubric of item contexts followed by an …
