| 摘要: | 本研究旨在探討練習方式與影像回饋型態對法式滾球射擊擲準技能準確性及技能品質與保留之影響。本研究對象以120名無法式滾球運動經驗之大學男女生（平均身高：169.1±8.29 cm：體重60.61±12.9公斤：年齡19.18±1.16歲）。經二週基礎射擊擲準技能課程學習後，依技能表現將測驗成績平均排序分配為:變異練習組、固定練習組、變異練習＋側後影像回饋型態、變異練習＋側面影像回饋型態、固定練習＋側後影像回饋型態、固定練習＋側面影像回饋型態等共六組，各組20名。正式實驗施以六週，每週一次的實驗操作，並於實驗開始前結束及結束後隔週實施前測、後測與保留測驗，本研究以練習方式與影像回饋型態為自變項，以射擊擲準及品質技能為依變項，以二因子混合設計變異數分析，若交互作用達顯著，則進行單純主要效果檢定，再達顯著水準則進行LSD事後比較。結果發現；在後測階段，以技能準確性固定＋側面影像回饋組的效益最佳，技能學習品質以固定練習組的效益最佳；而在保留測驗階段經事後比較的技能學習品質，則以變異＋側後影像回饋組的效益最佳。本研究結論為：以固定＋側面影像回饋、變異練習＋側後影像回饋等兩者對法式滾球射擊擲準技能均有正面的影響。
關鍵詞：技能品質、變異練習、回饋型態
Abstract
In this study, the main purpose is to discuss effects of practice styles and Feedback on Skill learning of Pétanque Shooting, and the quality of learning and retention of skills. 120 university students who have no Pétanque experience were served as participants (average height of 168.5 ± 12.3 cm：body weight 56 ± 12.6 kg：aged 19.18±1.16 years) participants were divided into variable practice group, constant practice group, variable practice+ behind side video feedback style, variable practice+ a flank video feedback style, the constant practice+ behind side video feedback style, constant practice+ a flank video feedback style , Six groups, each group of 20. Official experimental effects to six week, weekly once of experimental operation ,before the experiment begins, and ending before and after every other week to pre-test, and post-test after retention test, this research to practice styles and Feedback for the independent variable take the shooting acquisition and shooting learning quality for dependent variable, by mixed design of two-way ANOVA interactive role up significantly p<.05, is on the group between to LSD for after comparison in Performance on stage, constant practice + a flank video feedback style benefit best, skills performance quality in immediately test stage by after comparison constant practice benefit best, skills performance quality in retained test stage by after comparison variable practice + behind side video feedback style benefit best. The result showed study: constant practice + a flank video feedback style, variable practice + behind side video feedback style both on Pétanque Shooting accuracy of the obverse side skills learning.
Key words: shooting learning quality, variable practice, feedback style |
