碩士 === 台北市立師範學院 === 初等教育學系 === 84 === The purpose of this study based on knowledge structure analysis technique is to analyze the concepts of the common factor and common multiple in the fifth grade mathematics of elementary schools , and then to develop a mathematics achieve ICCNP program developed by non-parameter item response theory (IRT) model was applied to probe the quantitative characteristic of test items and subject. Besides, the method of interview was also applied to find the learning bottleneck. The results of this study include: (1)Some concepts in these two units practiced too little caused the learning bottleneck , so teachers should design extra exercises. (2)The sequences of the curriculum should be arranged to fit different students for learning. (3)Six kinds of item characteristic curve have been found, and the flat in the curve presents the learning bottleneck . In summary, this study is pioneer and useful, including the quantitative and qualitative analysis. Applying IRT model in cognitive psychology research will be the new approach.
