本研究旨在探討不同回饋訊息對排球跳躍發球技能學習之影響。本研究受試者為大學體育課興趣選項排球選修課之45位男學生，平均身高171.8±5.75公分，平均體重63.6±7.47公斤，平均年齡21.9±1.91歲，受試者皆未學習過跳躍發球。以排球選修課二個班級，每班為一個組別分配到二個組別（口語回饋組和標準影像組）。並於前測後，接著進行為期8週，每週1次，每次一小時的實驗操作，並於實驗完後進行後測與7日之後保留測驗。本研究統計方法以單因子混合變異數分析來進行考驗。本研究之顯著水準為α=.05，p<.05。研究結果發現以下二點結論：
一、口語回饋組和標準影像組於後測無顯著差異。
二、口語回饋組與標準影像組之7日保留測驗無顯著差異。
The aims of this study was discussed the effects of different feedback model on volleyball jumping serve. The subjects were 60 university students that average height was 171.8±5.75 cm, average weight 63.6±7.47 kg, average age 21.9±1.91 years old. These students had not learned the volleyball jumping serve before. They were assigned to the four experimental groups randomly and carried the four weeks experiment period. This study took one-way ANOVA to test and set the significant level for all assumed tests at. 05. there were two recoveries as following:
1. In the post test, the oral feedback group and the standard image group had not reach the significant level.
2. In the 7-day retention, the oral feedback group and the standard image group had not reach the significant level.
