目的：本研究旨在探討提供KP回饋與結合影像回饋與否，對於桌球正手發球技能表現之影響。方法：本研究以30名國中學生為研究對象，隨機分派到控制組、KP回饋組、KP加影像回饋組，進行為期五天的桌球正手發平擊球教學，並於前、後實施桌球正手發平擊球之技能測驗，以混合設計兩因子變異數分析進行資料處理，顯著水準設定為α=.05。經結果分析後，獲得以下結論：(一)提供回饋訊息對桌球正手發平擊球技能表現有正向幫助。(二)KP加影像回饋訊息對桌球正手發平擊球技能表現優於單純KP回饋訊息。
Purpose: Thhe aim of this study is to understand the effects of knowledge performance and video feedback on the forehand grip of flat serve motor skill learning on table tennis. Methods: 30 junior high school students were randomly assigned to the control group, the KP group and KP + Video group, to carry out forehand grip of flat serve motor skill learning for 5 days, and the forehand grip of flat serve test was taken by the three groups before and after motor skill learning. The one-way ANOVA was used to compare the feedback effect on different groups, and the paired samplet-test was used to analyze the pre- and post-motor skill learning. Results: (1) The feedback which was offered to students could improve on the forehand grip of flat serve motor skill on table tennis. (2) The KP + Video group performed batter than the KP group on the forehand grip of flat serve motor skill learning on table tennis.
