Reducing the Impact of Inappropriate Items on Reviewable Computerized Adaptive Testing
In a test, the testing score would be closer to examinee’s actual ability when careless mistakes were corrected. In CAT, however, changing the answer of one item in CAT might cause the following items no longer appropriate for estimating the examinee’s ability. These inappropriate items in a reviewable CAT might in turn introduce bias in ability estimation and decrease precision. An early propo...
متن کاملBayesian Computerized Adaptive Testing
Computerized adaptive testing (CAT) comes with many advantages. Unfortunately, it still is quite expensive to develop and maintain an operational CAT. In this paper, various steps involved in developing an operational CAT are described and literature on these topics is reviewed. Bayesian CAT is introduced as an alternative, and the use of empirical priors is proposed for estimating item and per...
متن کاملComputerized Adaptive Testing
A method of item pool design is proposed that uses an optimal blueprint for the item pool calculated from the test specifications. The blueprint is a document that specifies the attributes that the items in the computerized adaptive test (CAT) pool should have. The blueprint can be a starting point for the item writing process, and it can be used to assemble item pools in a system of rotating p...
متن کاملComputerized Adaptive-Attribute Testing: Incorporating Psychological Principles with Assessment Practices in Computerized Adaptive Testing
The influence of interdisciplinary forces stemming from developments in cognitive science, mathematical statistics, educational psychology, and computing science are beginning to appear in educational and psychological assessment. Computer adaptiveattribute testing (CA-AT) is one example. The concepts and procedures in CA-AT can be found at the intersection between computer adaptive testing and...
متن کاملMental Health Computerized Adaptive Testing
Context: Mental health measurement relies upon antiquated approaches to the analysis, design and administration of psychiatric instruments. Objective: This study examines the utility of the combination of Item Response Theory (IRT) and computerized adaptive testing (CAT) for the calibration, administration, and scoring of psychiatric measurement systems. Design: To illustrate the application of...
