This study was to investigate whether with the aid of verbal cues, video modeling with verbal cues and self-video replay with verbal cues were effective in enhancing the free throw ability for female junior basketball beginners. Participants were 24 female learners aged 13 to 14 years with no or little experience in free throw shooting. With equal ability among groups, they were divided into four equal groups (n=6), (1) control group (CG), (2) verbal feedback group (VG), (3) verbal cues with videotaped modeling (VMG), and (4) verbal cues with video replay (VRG). After an observation of a video clip with successful shooting attempts by an expert player, all participants were given two days of acquisition sessions with 120 trials in total and a retention test one day after the practice sessions. Both scoring accuracy and shooting form were evaluated, and a two-way analysis of variance ANOVA (4 groups X 3 trials) with repeated measures on the trial factor was used to analyze the effects of four different feedback methods for two basketball skill performance. It was found that with the aid of verbal cues, both video modeling and self-video replay were effective in enhancing the basketball free throw form in female basketball beginners.

本研究旨在探討配合口頭回饋、示範錄像及自我重放錄像能否有效提升初中女籃球初學者之射罰球能力。24個參加者為中二級女生，他們被分成4個相等能力組別(n = 6)：(1) 對照組(CG)、(2) 口頭回饋(VG)組、(3) 示範錄像及口頭回饋(VMG)、(4) 自我重放錄像及口頭回饋(VRG)。評估內容包括投射準確度和動作技巧，並使用雙因素方差ANOVA分析不同的實驗組的表現。研究結果顯示，配合口頭回饋、示範錄像及自我重放錄像均能有效提升初中女籃球初學者之射罰球能力。
