| Abstract: | With the continuous research of the psychological and educational measurement theory combined with computer technology, based on computer adaptive test become a new type of test form. On analysis of the computer adaptive theory and the selection strategy of the item maximum information, the paper designs and implements an adaptive test system. In experiment, the value of student's evaluated capacity, the total information, the maximum information and the parameters of item are analyzed and summarized. The experiment shows that the system is effective. |
