立定跳遠發展階段觀察檢核表之多層面Rasch評分量尺模式分析

Assessing the developmental level standing long jump checklist by many-facet Rasch model

目的：利用多層面Rasch評分量尺模式分析立定跳遠發展階段觀察檢核表，典型的動作樣式、起跑高度與距離，將由起跳成份所決定。因此，將檢核表精簡成為起跳一個成份，只須觀察起跳時手臂和腿部動作。方法：採用觀察法，對象為國小一至三年級36位學生，以多層面Rasch模式來分析資料、篩選試題、受試者信度、失序問題，並建立具有等距特性的量尺分數。結果：以多層面Rasch評分量尺模式分析立定跳遠發展階段觀察檢核表，具有不錯的信度，題目適切性良好，符合單向度要求，接近有效測量的理想。結論：立定跳遠發展階段觀察檢核表具良好信、效度，未來將可提供實務檢核，以發展兒童動作學習之用。Pupose: To use the many-facet Rasch model to assess the developmental level standing long jump checklist. The classical motor style, height and lenght of the standing long jump based on the takeoff component. The checklist was used in one component which was takeoff, and it needed to observe the leg and arm action of standing long jump. Methods: The subjects were 36 students who were from the 1st grade to 3rd grade of an elementary school. The observation method and the many-facet Rasch model were used to analyze the data, screen poor items, reliability, disordered quesitons, and to establish interval rating scale. Results: The use of the many-facet Rasch mdoel to analyze the developmental level standing long jump had the reliablility, item-fit, and single dimension to close the effective estimation. Conclusion: The developmetnal level standing long jump checklist had the reliability and validity to check the motor skills of children.
