本研究旨在透過行動研究探討運動教育模式在國中實施的成效、遭遇的困難以及可行的解決策略。研究參與者為某新成立國中之三位體育教師，及其所教授的七年級學生十二班。依運動教育模式設計十二週廿四節之排球教學，資料蒐集方法包括參與觀察、教師反省札記、訪談以及學習反應量表，資料分析採持續比較法。研究結果發現：一、學生對運動教育模式抱持肯定的態度，在學習反應四點量表中多數得分超過 3分，包括喜歡程度、對認知、技能、情意的學習成效。對團隊戰術的認知以及情意的學習尤高，未來也都願意再參與這樣的課程。二、學生肯定運動教育模式的主要原因：能有較全面、完整、深入的學習；學習過程中同儕指導技能學習效果較佳；團隊合作及分組競爭比較好玩等。三、學生們最喜歡擔任的角色是選手，最不喜歡擔任的角色是隊長。四、教師對運動教育模式也持相當肯定的態度，認為不僅學生學習成效好，且上軌道後能減輕教師的負擔，未來都願意繼續使用此模式。基於上述結果，運動教育模式在國中實施成效良好，值得推廣。未來研究可與合作學習、理解式等理念相近之教學策略結合探討。

The purpose of this study was to determine the effects of using the sport education model in junior high school, the difficulties encountered, and the possible solutions by means of action research. The participants were three physical education teachers from a newly founded junior high school and the 12 classes they taught. According to the sport education model, 24 class periods of volleyball which lasted for 12 weeks were designed. Data collection methods comprised participant observations, teachers’ reflective journals, interviews, and students’ learning feedback forms as well as their learning attitude scales. The constant comparison method was used for data analysis. The results were as follows. First, the students viewed the design of the sport education model positively. Most of them gave a score of more than three out of the four-point learning attitude scale, which rated how much they like the course and the learning effects on the cognitive, psychomotor, and affective domains. They especially enjoyed learning the cognitive and affective aspects of the team tactics, and were all willing to attend this kind of curriculum again in the future. Second, the reasons why the students approved the sport education model were that they learned more comprehensively, the learning effects were better when taught by their classmates during the learning process, and that team cooperation and group competition were fun. Third, in terms of role playing, students loved playing the role of players the most. Their least favorite roles were captain. Finally, the teachers also held positive attitudes towards the sport education model. They considered the model capable of not only boosting the students’ learning effects, but reducing their workload as well because many responsibilities were transferred to the students. The teachers were all willing to continue adopting this model in the future. Based on the findings, the sport education model worked well in junior high school and is worth promoting. Possible future research directions would be the playing of roles in teams, gender interaction, and other teaching strategies, for example, the combination of cooperative learning with TGfU.
