使用Rasch二分模式來編製國小運動技能測驗給分量表

The Application of Rasch Dichotomous Model to the Construction of the Basketball-Throw Testing Grading Measure for Sixth Graders

目的：使用Rasch測量二分模式來編製國小六年級學生運動技能測驗給分量表。方法：研究對象是國小六年級學生體育課籃球教學504名學生的基本投籃測驗，使用WINSTEPS 2000電腦程式進行估計，試題的訊息加權適合度統計和偏離反應適合度統計，RASCH二分模式的均方是1和均方的期望值1一樣。結果：顯示Rasch測量二分模式模式能精確估計國小六年級學生的基本投籃能力。結論：為Rasch測量二分模式來編製國小六年級學生投籃測驗給分量表，是一種最佳的方法，可以編製有效的測量。

Purpose: In this study, the application of the item response theory to the construction of the basketball-throw testing grading measure for sixth graders. Methods: The subjects were the basketball-throw testing of five hundred and four for sixth grade students. WINSTEPS was used as an estimation tool for item calibration, item and person distribution map, model-data fit analysis, item difficulty estimation, and person ability estimation. Results: It makes to compare with model-data fit, the mnsq of Dichotomous Model is equal to expected value. Conclusion: Rasch dichotomous model can provide a suitable and solid base for grading in Psychomotor testing.
