Item Selection Methods in Polytomous Computerized Adaptive Testing
… of administering adaptive tests with polytomous items is in great need. With regard to the applicability of adaptive testing using polytomous IRT models, adaptive testing can use polytomous items of either rating scales, or in some testing situations of multiple choice. Additionally, the …

Graphical models for student knowledge: Networks, parameters, and item selection
… and, to a smaller extent, Multidimensional Item Response Theory), most tests that use these models ignore the structure of the sub-domains they diagnose, either treating them as independent or arbitrarily correlated. But, testing efficiencies may be available if the structural relationships …

Controlling item exposure for response time-informed item selection in computerized adaptive testing
… (MIC) by the expected response time for each item effectively reduced the average completion time for a test of fixed length while maintaining efficiency of ability estimation. However, this also resulted in an extremely skewed distribution of item exposure rates. To counter this issue, they …

The Adult Scale Of Parental Attachment-Short Form: Item Selection, Factor Structure, And Psychometric Properties
… developed with an emphasis on the instrument's item selection, factor structure, and psychometric properties. The ASPA, building upon attachment theory, is a self-report measure that assesses individuals' patterns of relating based on their relationships with both mother and father figures in …

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 …

Item selection methods in multidimensional computerized adaptive testing adopting polytomously-scored items under multidimensional generalized partial credit model
Four item selection methods are compared and investigated under three test formats in the context of Multidimensional Computerized Adaptive Testing (MCAT) delivering polytomous items partially or completely in tests. Item selection methods examined include Fisher information based D-optimality …

A study of the effect of music genre and intensity on ethnic menu item selection in a military dining facility
… genre and intensity on patrons' ethnic menu item selection of a military dining facility in the Southwestern United States. The extent to which ethnic music could influence associated ethnic menu items was examined; Three research questions were formulated to address this issue. The first …

Implementation of Optimal Design for Item Calibration in Computerized Adaptive Testing (Cat)
Item calibration in small sample conditions is an important research and practical issue. This thesis aims to solve this issue by implementing a promising method, optimal design. Contrary to traditional random item selection, optimal design matches examinees and pretest items for maximal …

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 …

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 …

Item parameter drift and online calibration
An important assumption of item response theory based computerized adaptive assessment is item parameter invariance. Sometimes, however, item parameters are not invariant across different test administrations due to factors other than sampling error; and this phenomenon is termed item parameter …

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) …

New methods of online calibration for item bank replenishment
"Item parameter calibration is important for tests based on item response theory, because the scoring, equating, bias analysis of the test, and item selection in adaptive tests are all based on the item parameters. As a test is continuously administered, item calibration needs to be conducted for …

Effective cognitive diagnostic assessment with computerized adaptive testing
… ability, that is, each examinee will receive items that are neither too easy nor too difficult. Consequently, CAT is a more efficient test mode compared to paper-and-pencil testing. With the advancement of technology, CAT became a viable option for test administration. The advantages that CAT …

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 …

Data-driven adaptive learning systems
… classification testing (CCT) tailors test items to learners' abilities so as to give a more efficient latent trait estimation. On the other hand, the learning plan (called policy) is another key component of such systems. It is the algorithm that designs the learning paths, or in other …

Item Properties and the Validity of Personality Assessment
… properties of personality questionnaire items that can affect their validity, as measured by comparing self-ratings with roommate ratings on a series of personality questionnaires. The item properties under investigation included item content saturation, item social desirability, and mean …
