Estimating the Examinee's Ability and the Standard Error in its Estimation according to Computer Adaptive Testing Strategy.

This study aims at estimating the examinee's ability and the standard error in estimating according to computer adaptive testing strategy. In order to achieve the goals of the study, an item pool of fifty five multiple- choice questions was prepared. It aims at measuring the examinees' ability in the area of measurement and evaluation. Two tests of thirty seven multiple- choice questions are devised: the computer linear test type, and the computer adaptive tests. The calibration sample (290 students) takes the computer linear test while the other group takes computer adaptive tests. SPSS, Winsteps, version 2.88 and Fasttest Pro-2006 are used to analyze the data. The results of the study reveal that there are statistically significant findings in favor of the computer adaptive test (? = 0.05). There are also statistically significant findings in the means of standard error estimation in favor of the computer linear test (? = 0.05). It has also been found that the computer adaptive test group outperforms the other group in the mean of the number of items. In the light of the study findings, a number of conclusions and recommendations are suggested.
