On-the-fly assembled multistage adaptive testing
… tests such as the computerized adaptive test (CAT) and multistage tests (MST) have been widely implemented in many large scale tests. In 2000, some testing organizations uncovered some pitfalls of CAT after it was applied to large scale testing. After these instances, many …

Computerized Adaptive Testing---New Developments and Applications
Computerized adaptive testing (CAT) has become a very important testing mode since it was introduced into the testing field in the early 1970's. It has clear advantages over the traditional paper-pencil testing in many aspects including shorter tests and more efficient score reporting. However, it …

Effective cognitive diagnostic assessment with computerized adaptive testing
… a different pedagogical approach. Computerized adaptive testing (CAT) is a mode of testing that has gained popularity in recent years, due to its advantages. It tailors the test according to the examinees' ability, that is, each examinee will receive items that are neither too easy nor too …

Item Selection Methods in Polytomous Computerized Adaptive Testing
… technology, the importance 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 …

Computerized Adaptive Testing and Equating Methods With Nonparametric IRT Models
The flexible forms of nonparametric IRT models make test equating more challenging. Though linear equating under parametric IRT models is obvious and appropriate, it might not be appropriate for nonparametric models. Two approaches are proposed for test equating and examined through simulation as …

Computerized Adaptive Testing and the Experience of Flow in Examinees
In recent years, comparisons between computerized adaptive tests (CAT) and paper-and-pencil tests (P&Ps) have focused less on equivalency and more on the construct validity of shifting between the modalities. Examinee motivation is one area of concern, including test and computer anxiety. One type …

Application of Appropriateness Measurement to a Problem in Adaptive Testing
… of 1-5 random responses to 15, 20 and 25-item adaptive tests were examined using simulation. Results indicated that adaptive tests are not robust to initial sequences of misinformative responses. Significant underestimation of ability occurred when as few as the initial 2 responses were random. …

Kullback-Leibler information and its applications in multidimensional adaptive testing
… item selection methods in multi-dimensional adaptive tests (MAT) which are based on these two information measures. The KL information index (KI) method is then discussed and two theorems are derived to quantify the relationship between KI and item parameters. Due to the fact that most of the …

Some theoretical and applied developments to support cognitive learning and adaptive testing
… diagnostic Modeling (CDM) and Computerized Adaptive Testing (CAT) are useful tools to measure subjects' latent abilities from two different aspects. CDM plays a very important role in the fine-grained assessment, where the primary purpose is to accurately classify subjects according to the …

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 …

Toward Culturally Responsive and Equitable Testing: Innovative Psychometric Analyses on Contextualized Measurement and Adaptive Testing
… aspects of culturally responsive and equitable testing. To that end, three coordinated studies were conducted to gather validity evidence based on cultural characteristics of contextualized items, students, and multigroup fairness from empirical and simulated datasets. The first study …

The effectiveness of using multiple item pools to increase test security in computerized adaptive testing
… and item pool usage balance for Computerized Adaptive Testing (CAT). Also, the extent to that multiple item pools can reduce the bias of CAT in the presence of possibly compromised items will be explored. Item selection algorithms were designed using three conditions: item pool configuration …

The Impact of Local Item Dependence on Computer Adaptive Testing given Between and Within Testlet Adaptivity
… in educational tests. Additionally, computerized adaptive testing (CAT) is a mode of testing where the test forms are created in real time tailoring to the test taker's previous responses. CATs have gained popularity because they produce a more accurate test score estimate within a shorter time …

Advancements in test security: preventive test assembly methods and change-point detection of compromised items in adaptive testing
Chapter 1: Test security is as longstanding as testing itself. The broad issues are introduced very briefly, then the specific matters pertaining to computerized adaptive testing (CAT) are discussed. The framework of CAT is established in detail, then the vital security concerns of item exposure …
