For the present, higher-order item response theory model almost mainly analyzes the single independent item, but little concerns about the testlets which are more and more frequently used in large-scale standardized tests. The purpose of this research is to analyze testlets test data on the base of hierarchical assessment framework by the method of simulated experiment. The goal is to estimate the accuracy on the ability parameters, the item parameters, the testlet effects, and the variances of testlet effect by controlling the factors including the number of the domaim scale, the number of items, the number of testlets, the variances of testlet effects ,the correlations. According to the results, reference is offered to analyze hierarchical test data. The results are also to show that full estimation can obtain more complete and accurate estimated values. As the number of the domaim scale, the number of items, the number of testlets, the correlations increase, the accuracy of ability estimated values increases. As the variances of testlet effect increase, the accuracy of ability estimated values decreases. However, the results of the item parameters, the testlet effects, and the variances of testlet effect are irregular. Bor-Chen Kuo 郭伯臣 2011 學位論文 ; thesis 190 zh-TW |

碩士 === 國立臺中教育大學 === 教育測驗統計研究所 === 99 === The hierarchical assessment framework is the current tendency in many large-scale standardized tests, and it can get the overall ability and the domain ability simultaneously and be accurately estimated by the suitable way. For the present, higher-order item response theory model almost mainly analyzes the single independent item, but little concerns about the testlets which are more and more frequently used in large-scale standardized tests.
The purpose of this research is to analyze testlets test data on the base of hierarchical assessment framework by the method of simulated experiment. The goal is to estimate the accuracy on the ability parameters, the item parameters, the testlet effects, and the variances of testlet effect by controlling the factors including the number of the domaim scale, the number of items, the number of testlets, the variances of testlet effects ,the correlations.
According to the results, reference is offered to analyze hierarchical test data. The results are also to show that full estimation can obtain more complete and accurate estimated values. As the number of the domaim scale, the number of items, the number of testlets, the correlations increase, the accuracy of ability estimated values increases. As the variances of testlet effect increase, the accuracy of ability estimated values decreases. However, the results of the item parameters, the testlet effects, and the variances of testlet effect are irregular.
