由於數位學習早已蔚為趨勢，運用課程管理系統來整合各教師的網路教學課程也早已是國內外各大學推行有年的作法。國防大學由於許多主客觀條件與一般民間大學不同，推行課程上網自有其特殊之利弊與考量。本研究於九十四學年度下學期起針對理工學院大一、大二及專二學生開設線上非同步英語課程以配合傳統課堂教學，並於課程結束後對於各班學生的使用狀況實施問卷調查，以期了解網路教學在各教師教學上的成效與學生對於使用教學平台的喜好及評價等。研究期間各英文老師製作課程簡報檔案，利用理工學院資訊系教師自行研發的課程管理系統—數位學習館—將自己所授課程上網，並依課程需要使用全部或部份數位學習館所提供的功能。學期末的調查結果顯示在102 份有效問卷中，94%的學生認為線上非同步課程有助於英文學習。英文課使用數位學習平台最大的優點是課程資料方便取得（75%）。最大的缺點是網路使用受到限制，無法經常使用（66%）。學生最常使用的數位學習功能是講義下載，其次是參考資料下載；而他們認為對英文課最有幫助的功能也是講義及參考資料上網。50%和34%的學生認為英文課必須或可以使用線上非同步課程來輔助學習，16%沒意見，無人反對使用。本研究對於軍事院校進一步發展結合非同步數位學習與傳統課堂教學的混合課程應具有參考價值。

This study evaluates and analyzes the effects of three supplementary asynchronous online courses on English teaching and learning from the perceptions of students who enrolled in one of those courses during the spring semester of 2006. The courses were built on a faculty-developed course management system—Digital Learning Lab (DLL). The findings collected from a survey questionnaire given to the students at the end of the semester show that 94% of the students agrees to the helpfulness of DLL to English learning. The greatest advantage of DLL is the convenience of retrieving course documents whereas the greatest disadvantage is the limitations of web access inside the campus. The most frequently used function is downloading course handouts, followed closely by downloading reference documents. These two functions are also recognized as the most helpful tools to students’ learning in English courses. A majority of the students (84%) supports the use of DLL in English courses while nobody objects to it. The experience of adopting an asynchronous online component to supplement a traditional face-to-face English class can be used as a reference for developing other blended courses at military academies.
