中文摘要 | 當代電腦化適性測驗的發展往往因為試題編製成本居高不下而受到限制,晚近電腦科技與認知科學的進展,讓更富經濟效能的試題複製理論和技術漸臻成熟。然而,試題複製所產生的參數不確定性,自然會造成能力估計的誤差。因此,控制試題參數的不確定性成為自動化命題技術探討的重要課題。本研究以認知成分分析為基礎,針對國小學童圖形推理作業,建立試題構成原則。文中提出19個試題模型,複製產生103個試題,並針對616名國小四、五、六年級學生施測後,以題目反應理論單參數模式估計試題難度參數。整體而言,試題模型內難度變異的平均極小(σ 2=.053),顯示研究中所採用難度參數變異與試題認知成分交互檢核的模型微調策略,可以依據構念內含的認知成分,有效將試題模型內的難度參數變異降低到合理的水準。 |
英文摘要 | Implementation of computerized adaptive testing is limited due to costly expense and time-consuming item production. Taking advantage of the advanced computer technology and cognitive science, more economical and efficient item cloning theories and technologies are evolved into feasibility. However, item parameter uncertainty induced by item cloning causes ability estimate error inevitably. How to control item parameter uncertainty becomes a critical issue on the automated item generation. Based on cognitive component analysis literatures, the present study attempts to establish item generation principles for figural matrix tasks. Nineteen item models are developed to generate 103 isomorphic item variants. The response data of 616 4th to 6th grade students is used for Item Response Theory (IRT) one-parameter model item parameter calibration. Whenever the variance of difficulty parameters within an item model is relatively large, a related component will be identified to establish a new item model. Overall, the average variance of item difficulty parameter within item models is very small (σ 2=.053). The results suggest that the item modeling mechanism accomplish a reliable control for item parameter. |
