Item Response Times in Computerized Adaptive Testing
Computerized adaptive testing (CAT) provides a score as well as item response times. However, the investigation of what additional meaning may result from response time information is of particular interest. Data from 5,912 young men on a computerized adaptive test were available. Earlier studies indicate longer response times for wrong responses. This was replicated in larger settings. However...
متن کاملComputerized Adaptive Testing With Item Cloning
To increase the number of items available for adaptive testing and reduce the cost of item writing, the use of techniques of item cloning has been proposed. An important consequence of item cloning is possible variability between the item parameters. To deal with this variability, a multilevel item response (IRT) model is presented which allows for differences between the distributions of item ...
متن کاملA Strategy for Controlling Item Exposure in Multidimensional Computerized Adaptive Testing
While computerized adaptive tests have enjoyed tremendous growth in the past decade, satisfactory solutions for many important problems are still unavailable. Among these problems, a critical one is the control of item exposure rate. Because adaptive algorithms are designed to select optimal items, they tend to choose items with high discriminating power. Thus, these items are selected far more...
