2005年大專運動會木球競賽之球道分析

The analysis of woodball fireway at 2005 Intercollegiate Athletic Competitions of R. O. C

目的：在以試題反應理論分析木球球道之設計。方法：以2005年大專運動會木球競賽之球道及成績作為資料之分析，利用Facets電腦程式進行三層面Rasch模式分析。結果：可以對球道整體進行描述與分類，並可以檢測不良的球道；結論：為木球的球道設計雖然重要，球門區的選擇同樣不得輕忽，否則選手的真正實力將受非確定因素的影響。

Purposes: This study were to analyze the setting of woodball fireway with Item Response Theory (IRT). Methods: The data of the evaluation of woodball fireway and scores in 2005 Intercollegiate Athletic Competitions was analyzed. The FACETS software was used to analyze three-facet Rasch model. Results: Through IRT we could describe and classify the performance of woodball fireway and scores. Furthermore, the player's unexpected response was also tested and overtook. Conclusion: The Item Response Theory could better analyze woodball fireway and scores, and that setting of woodball fireway was as important as gate area .
