本研究的目的在於探討船球推擲之教學效果。受試對象為國立臺北師範學院體育系23名男生，受試者平均年齡為19.2±1.1歲；平均身高為173.7±5.7公分；平均體重為67.2±7.5公斤。 經過四週十二節(600分鐘)的推鉛球教學後，測驗其側向滑步、背向交換步及背向滑步的推船球成績。本研究所得資料以相依樣本變異數分析及相依樣本t檢定進行統計分析，結果經討論後，獲得結論如下： 一、推船球教學後成績，由學前的9.67公尺提升至10.13公尺，進步幅度達0.48公尺，其差異達p<.05的顯著水準。 二、側向滑步、背向交換步及背向滑步三種姿勢推船球之成績差異比較未達顯著水準(p>.05)。

　　　　　The primary purpose of this study was to analyze the teaching effect on different shot put styles. The subjects for this study were 23 male freshmen (age: 19.2±1.1 years, weight : 67.2±7.5kg, and height : 173.7±5.7cm) studying the Department of Physical Education of National Taipei Teachers College. The performances of side-twist, back-twist (change-of-step) and back-twist(glide) were measured after twelve sessions (600 minutes) of practices. The analyses of repeated t-test and One Way ANOVA were conducted, and the summary of results was listed as follows: (1)Their shot put records had significant improvement from 9.67 meters to 10.13 meters (p<.05). (2)There were no significance among the side-twist, back-twist I (change-of-step) and back-twist II (glide) of distance.
