本研究旨在建置一個具有可移動性(mobility)、現成(ready-made)及自給自足(self-contained)三個重要特性的全新教學環境 － 可移動式數位學習中心。當可移動式數位學習中心被建置完成之後，可以將其運送到(1)災區--以提供災民們暫時性的教學環境;(2)未開發國家--以提供因為經濟狀況不佳而喪失學習機會的人們進行學習;(3)偏遠地區--以提供因為當地地理位置偏遠而喪失學習機會的居民進行學習。
可移動性是指可以很容易地被運送到不同的地方;現成是指所有提供教學環境所需要用到的元件，如基地台、可移動式數位學習中心伺服器、電源供應器、平板電腦及充電器等設備都是預先配備於可移動式數位學習中心之內;自給自足是指不需要額外提供任何資源，如網路連線和電力來支援其運作。因此，當可移動式數位學習中心被運送至目的地，立即就可以被用來進行教學活動。本研究提出了可移動式數位學習中心全面性的概念、主要元件、系統設計與實作及教學活動設計。本研究也進行了一個實驗性的英文情境式教學活動以評估使用可移動式數位學習中心在教學活動中所帶來的影響。最後，提出了一些可移動式數位學習中心的未來研究方向。

This research aims to construct a brand-new teaching and learning environment called Transportable Digital Learning Center (TDLC) which contains three important features: mobility, ready-made and self-contained features. TDLC is constructed for providing learning opportunities to (a) people in disaster areas with a temporary teaching and learning environment before their reconstructions finished; (b) people in undeveloped countries who do not have learning opportunities due to the lack of financial resources; (c) people in geographically isolated places like deserts or high mountain areas who do not have learning opportunities due to the isolation of their geographic locations.
The mobility feature means that it can be transported to different geographic locations easily; The ready-made feature means that all the components of a TDLC such as access point, TDLC Server, power supply, Tablet PCs and charging devices used to provide a teaching and learning environment are all equipped inside the TDLC in advance; Self-contained feature means that it is unnecessary to provide it with any other resources like network connections and electricity to sustain its operation. Therefore, once a TDLC has been transported to its destination, it can be used to conduct teaching and learning activities immediately. In this paper, we describe the overall concepts, main components, system design and implementation, and teaching & learning activity design of TDLC. We also conducted an experimental English Situated Learning activity to evaluate the effects of using TDLC in the teaching and learning activity. Finally, some future research topics of TDLC are proposed.
