本研究的目的是：應用概化理論的決斷研究探討運動技能測驗適當的計分方式。 研究對象是初級桌球班 219 名女生的正手擊球測驗， 利用概化理論、重複量數單因子變異 數分析和鄧肯法多重事後比較，研究結果，得到下列結論：概化理論可提供運動技能測驗選 擇適當計分方式的參考。

　　　　　The purpose of this study was to apply the decision study of generalizability theory dociding the goodness of fit scaling in the psychomotor test. The subjects were 219 females in junior table tennis classes. Forehand stroke tests ware given. Data were analyzed using the decision study, one-way repeated measure analysis of variance, and Duncan's multiple range test. Based on the results of this study, the conclusions were drawn: the generalizability theory provides some information to determine appropriate the scaling in psychomotor test.
