| Summary: | 碩士 === 國立臺中教育大學 === 教育測驗統計研究所 === 100 === The purpose of this study was to explore the the performace of congnitive diagnostic model with different Q matrix designs, the expert knowledge based structure and the student knowledge based structure.The unit “Factor, Multiple, Common Divisor and Common Multiple” was used to develop a test .This test was administratered to the fifth graders in the Taiwan elementary school. Using the Pearson product-moment correlaction coefficient ,the relations of item parameters between DINA model and three-parameter IRT model were explored . With empirical data the performance of DINA model with different Q matrix designs was investigated.
The results showed in the following：
1.There was significant relationship between 1-s-g parameter in DINA model and the discrimination parameter in IRT model.
2.The diagnosis accuracy of DINA model increased when the Q matrixs were designed with the expert knowledge structure and with the student knowledge structure.
3.With two types of the hierarchical Q matrix, the performance of the expert knowledge structure was better than that of the student knowledge structure.
