    Abstract: 確保學生學習成效是高等教育所高度關注的議題,近年來在大數據的引領下,透過大量的蒐集數據,進行數據分析,尋求線索與證據,採取合適行動以提升學生的畢業率和留校率,廣受重視。近期研究文獻顯示,學習先期預警對提升學習成效有顯著效益,故本研究將致力於設計一個先期預警完整系統架構,並著重在研究先期預警的偵測模式及適用屬性選擇。本論文使用SAS的決策樹模組進行先期預警的預測,實驗中分別測試A、B兩門課及各種屬性組合的決策樹模型,以選出可提供最高預測正確率的屬性組合。實驗結果發現A門課最佳屬性組合為點名及小考,其正確性(Accuracy)為78%;B門課最佳屬性組合為作業及小考,其正確性為82%。由實驗結果可知,不同的課程因為教學策略或方式的不同,可使用不同的屬性資料以產生最適預測模型。
