目的：本研究目的係探討目標設定介入對國小羽球選手殺球表現之影響情形。方法： 以四位平均年齡10.33（SD = 0.42）歲國小四年級羽球選手為研究參與對象，採單一受 試者A-B-C 實驗設計。本研究共12 週，其中基線期、介入期及追蹤期各四週，所有受 試者每週需測驗兩次殺球表現，在介入期時則被要求每週至少2.50% 的進步幅度作為目 標，並在每次測驗後填寫目標設定日誌檢核表以檢驗目標設定介入之程度。所得資料以 視覺分析及C 統計進行分析檢驗目標設定介入對羽球殺球表現之效益。結果：目標設定 介入能有效提升四位受試者之殺球表現，且在追蹤期有三位受試者的殺球表現仍持續穩 定上升。結論：研究發現四週八次的目標設定介入可有效提升國小四年級羽球選手之殺 球表現，亦能在目標設定撤除後具有良好的殺球表現。

Purpose: This study was to explore the effect of goal setting intervention on badminton smash performance for elementary school badminton players. Method: Four elementary school badminton players in the fourth-grade average age of 10.33 (SD = 0.42) years old as the research subjects, the single case design for A-B-C was used for the present study. This experiment had a total of 12 weeks which the basis phase, the intervention phase and the withdrawal phase were four weeks each. All subjects were required to test their smash performance twice a week. During the intervention phase, they were required 2.50% to improve, and complete the goal setting log checklist after each test to verify the extent of goal setting involvement. The obtained data were analyzed by visual analysis and C-statistics to examine the effect of goal setting intervention on badminton smash performance. Result: The goal setting intervention could effectively improve the smash performance of the all subjects. Furthermore, there were three participants increase steadily on smash performance during the withdrawal phase. Conclusion: The study found that eight times of goal setting interventions in four weeks can effectively improve thesmash performance for the fourth-grade of primary school badminton players and can also maintain an optimal performance effect after the goal setting was removed.
