Implementation of Optimal Design for Item Calibration in Computerized Adaptive Testing (Cat)
… items are seeded at the earlier stages of a CAT, optimal design uses two types of MLEs of ability levels: using current ability estimates in calculating item response probabilities at the item selection step, and using the final ability estimates at the item parameter estimation step. Random …

Controlling item exposure for response time-informed item selection in computerized adaptive testing
… issue, they recommended the use of the a-stratification with b-blocking (ASB) method, which balanced item exposure very well but at the cost of compromising on the average test time reduction and increasing the error of ability estimation. Therefore, the current study investigated several …

Association Between Health-Related Perceptions and Treatment Outcomes in an Interdisciplinary Pain Management Program
… METHOD: Initial and discharge responses to Computerized Adaptive Testing (CAT) items were collected. Select measures, such as the PMQ (Pain Medication Questionnaire), BIPQ (Brief Illness Perception Questionnaire), PROMIS Global Health, Composite Pain Rating, and other PROMIS measures were …

Sequential mastery detection and Bayesian learning promotion under cognitive diagnosis models
E-learning assessments are becoming a common educational medium to instruct fine-grained skills in modern pedagogy. To accentuate the advantages of e-learning assessments, it is vital to automate the process of instruction and advancement in accordance with the learning progress of each individual. …

Explore the moving sample size used in a procedure for detecting compromised items based on item response theory
A computerized adaptive testing (CAT) system can provide tests for examinees continuously, so items in the item bank face the risk of being leaked. The IRT-based detection procedure developed by Zhang and Li (2016) is further studied in this thesis, which is designed to identify compromised items …

The Impact of Local Item Dependence on Computer Adaptive Testing given Between and Within Testlet Adaptivity
In educational tests, a group of questions related to a shared stimulus is called a testlet (e.g., a reading passage with multiple related questions). Use of testlets is very common in educational tests. Additionally, computerized adaptive testing (CAT) is a mode of testing where the test forms are …

The effectiveness of using multiple item pools to increase test security in computerized adaptive testing
… exposure control 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 …

Some theoretical and applied developments to support cognitive learning and adaptive testing
Cognitive 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 …

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 …

Extension of the item pocket method allowing for response review and revision to a computerized adaptive test using the generalized partial credit model
Computerized Adaptive Testing (CAT) has increased in the last few decades, due in part to the increased use and availability of personal computers, but also partly due to the benefits of CATs. CATs provide increased measurement precision of ability estimates while decreasing the demand on examinees …

Comparison of four stopping rules in computerized adaptive testing and examination of their application to on-the-fly multistage testing
Computerized adaptive testing (CAT) is a powerful and efficient approach in educational testing for both estimating ability and classifying examinees into groups. When the purpose is to classify students as either proficient or not proficient in ability, an accurate estimate is not necessary, and …

Data-driven adaptive learning systems
"Adaptive learning systems are capable of providing more adaptive and efficient assessment and learning experiences for learners than traditional classroom settings. A conventional adaptive learning system involves a learner, a latent trait estimator, and a learning strategy/plan. The latent trait …

Effective cognitive diagnostic assessment with computerized adaptive testing
"Educators are seeking out mechanisms for reporting diagnostic information about the strengths and weaknesses of each student. Cognitive diagnostic assessment (CDA) is a form of assessment that could facilitate the educators in discovering their students' strengths and weaknesses. In CDA, the …

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 …
