本研究旨在了解國中籃球校隊學生在運動情境的道德發展層次，以及籃球校隊訓練是否有助於促進國中學生的運動道德發展；研究工具為運動道德判斷問卷；研究對象為 219位國中八、九年級男生，其中 99位為籃球校隊學生，120位為同班 (年級)的非校隊學生，有效問卷的回收率為 73%；資料處理採用描述性統計及卡方檢定，統計顯著水準為 α=. 05。研究結果及結論為：國中籃球校隊學生在運動情境中的道德發展朝向兩極化發展趨勢，符應其年齡者 (習俗道德期)僅佔 22.6%，而落後 (前習俗道德期)與超前 (後習俗道德期)於其年齡者則各佔39.7%及 37.7%。國中籃球校隊學生與一般學生，在運動情境中的道德發展不具有顯著差異存在，此結果顯示 1.6年的籃球校隊訓練歷程不會影響國中學生在運動情境中的道德發展。
