緒論：本研究目的為瞭解教具補助游泳教學之學習成效，探討捷泳教學時穿著短版 蛙鞋是否能提升學生運動表現，研究對象為臺中市國民小學中、高年級一般學生。方法： 實驗前需完成 25 及 50 公尺捷泳打水及徒手捷泳前測，依成績將研究對象分為第一與第 二梯次各 40 人，訓練當天第一與第二梯次各有 20 人隨機分配穿著短版蛙鞋，拆成使用 短蛙組與未使用一般組，接著進行三週相同教學課程，並使用兩支 SEIKO S-120 碼表及 一台 MARIUM 電子多功能計時器 MAR-3850，監控並記錄 25 及 50 公尺訓練時間與休 息時間，所得數據以成對樣本 t 檢定，分析同組別捷泳前、後測驗成績之差距；以獨立 樣本 t 檢定，分析不同組別捷泳後測成績之差異。結果：同組別不論是 25 公尺及 50 公 尺捷泳，後測成績皆優於前測成績，均達顯著差異 (p < .05)；而不同組別的短蛙組在後 測 25 公尺及 50 公尺捷泳成績都優於一般組別，達顯著差異 (p < .05)。結論：不論研究 對象是否穿著短版蛙鞋，經過三週的捷泳教學皆能提升捷泳運動表現，而使用短版蛙鞋 搭配教學，不僅能利用較大阻水面積改善打水技術，獲得更好的訓練成效。

Introduction: The purpose of this thesis was to examine the effectiveness of applying teaching aids in swimming lessons, together with the discussion of whether wearing short fins could enhance examinees’ sport performances in crawl stroke swimming lessons. Taichung city elementary school middle and high graders without special conditions. Methods: 25 meters and 50 meters crawl stroke kicking and unarmed pre-tests were required before the experiment. The subjects would be divided into the first and second sections according to their pre-test scores, and there would be 40 people in each group. On the training day, there would be 20 people in both sections randomly chosen to wear short fins, at the same time, they would be divided into short fins using group and non-using group. Later on, both groups would receive identical training lessons for three weeks. In this experiment, we would use two SEIKO S-120 stopwatches and a MARIUM electronic multi-function timer MAR-3850 to monitor and record the 25 meters and 50 meters crawl stroke training time and break time. Meanwhile, the data collected from the experiment would be used to analyze the division between crawl stroke pretest and post-test scores of a same group through individual sample t test. Results: The post-test scores in both 25 meters and 50 meters crawl stroke groups all appeared to be better than pretest scores, and the scores had all reached obvious standard deviation (p
