In educational testing, one is concerned to get as much information as possible about a given examinee from each minute of testing time. Maximum information is obtained when the difficulty of each test exercise matches the estimated ability level of the examinee. The goal of adaptive testing is to accomplish this. Adaptive patterns are reviewed…

Tatsuoka, Kikumi K. – 1985
This paper introduces a probabilistic model that is capable of diagnosing and classifying cognitive errors in a general problem-solving domain. Item response theory is used to deal with the variability of response errors. Responses from a 38 item fraction addition test given to 595 junior high school students are used to illustrate the model.…
