Abstract:
Multidimensional adaptive testing (MAT) can improve the efficiency of measuring traits that are known to be highly correlated. Content balancing techniques can ensure that tests fulfill requirements with respect to content areas, such as the number of items from various dimensions (target rates). However, content balancing does not restrict the order in which items are selected from dimensions. If multiple dimensions are measured with MAT, intermixing items from different dimensions might invalidate properties of those items, which are known from calibration studies without mixed item content. To avoid this, the known correlations between traits can be used to increase efficiency of the ability estimation only without intermixing items from different dimensions. In this simulation study, MAT allowing items to be intermixed between dimensions is compared to Constrained MAT (CMAT) that does not allow intermixing items between dimensions for items with between-item multidimensionality. As expected, MAT achieved the greatest reliability for equal target rates; however, CMAT with items administered in a pre-specified order dimension by dimension was not disadvantageous for unequal target rates.

Abstract:
The assessment of a person's traits is a fundamental problem in human sciences. Compared to traditional paper & pencil tests, computer based assessments not only facilitate data acquisition and processing but also allow for adaptive and personalized tests so that competency levels are assessed with fewer items. We focus on speeded tests and propose a mathematically sound framework in which latent competency skills are represented by belief distributions on compact intervals. Our algorithm updates belief based on directional feedback; adaptation rate and difficulty of the task at hand can be controlled by user-defined parameters. We provide a rigorous theoretical analysis of our approach and report on empirical results on simulated and real world data, including concentration tests and the assessment of reading skills.

Abstract:
The assessment of a person's traits such as ability is a fundamental problem in human sciences. Compared to traditional paper and pencil tests, computer based assessment not only facilitates data acquisition and processing, but also allows for real-time adaptivity and personalization. By adaptively selecting tasks for each test subject, competency levels can be assessed with fewer items. We focus on assessments of traits that can be measured by determining the shortest time limit allowing a testee to solve simple repetitive tasks (speed tests). Existing approaches for adjusting the time limit are either intrinsically non-adaptive or lack theoretical foundation. By contrast, we propose a mathematically sound framework in which latent competency skills are represented by belief distributions on compact intervals. The algorithm iteratively computes a new difficulty setting, such that the amount of belief that can be updated after feedback has been received is maximized. We rigorously prove a bound on the algorithms' step size paving the way for convergence analysis. Empirical simulations show that our method performs equally well or better than state of the art baselines in a near-realistic scenario simulating testee behaviour under different assumptions.

Abstract:
The assessment of a person's traits such as ability is a fundamental problem in human sciences. We focus on assessments of traits that can be mea- sured by determining the shortest time limit al- lowing a testee to solve simple repetitive tasks, so-called speed tests. Existing approaches for ad- justing the time limit are either intrinsically non- adaptive or lack theoretical foundation. By con- trast, we propose a mathematically sound frame- work in which latent competency skills are rep- resented by belief distributions on compact inter- vals. The algorithm iteratively computes a new difficulty setting, such that the amount of be- lief that can be updated after feedback has been received is maximized. We provide theoretical analyses and show empirically that our method performs equally well or better than state of the art baselines in a near-realistic scenario.

Abstract:
Multidimensional adaptive testing (MAT) allows for substantial increases in measurement efficiency. It was examined whether this capability can be used to report reliable results for all 10 subdimensions of students' literacy in reading, mathematics and science considered in PISA. The responses of N=14,624 students who participated in the PISA assessments of the years 2000, 2003 and 2006 in Germany were used to simulate unrestricted MAT, MAT with the multidimensional maximum priority index method (MMPI), and MAT with MMPI taking typical restrictions of the PISA assessments (treatment of link items, treatment of open items, grouping of items to units) into account. For MAT with MMPI the reliability coefficients for all subdimensions were lager than .80, as opposed to sequential testing based on the booklet design of PISA 2006. These advantages slightly lessened with the incorporation of PISA-typical restrictions. The findings demonstrate that MAT with MMPI can successfully be used for subdimensional reporting in PISA.
