摘要

在本篇論文中，我們提出了一個行動學習格網的平台架構，主要解決了數位學習平台上資源分散而無法有效共享的問題，並且促成了各個學習物件彼此之間能夠協同的作業且有效地再使用。由於在Web服務中對於資源的描述仍缺乏良好的定義與服務層級協調分派的能力，因此無法有效管理各地分散的資源並達成服務間的協同作業。相對於此，由Web服務與格網技術所衍生的格網服務架構，則提供了對於各項服務良好的描述以及管理的基礎結構。因此行動學習格網以格網服務技術為基礎，結合行動無線裝置與相關技術提供了一個行動的、協同作業的、資源能有效控管與分享的無線學習平台。並且利用 TME GAIA當成格網引擎，實作此平台，在實驗中，製作遵循 SCORM標準的英文學習物件，利用Nokia 7210手機來進行學習。

In this paper, a grid framework for mobile learning was proposed to solve the difficulties of sharing learning resources distributed on different e-Learning platforms. Moreover, this framework makes the learning objects can collaborative work and reuse effectively. Since web services is still short in well definition and dispatch ability in service layer for resources description, so that the distributed resources cannot effectively be managed and reached the collaboration among the services. For this reason, a grid service framework was generated from web services and grid technology which support well services descriptions and management mechanism. The m-Learning Grid is based on grid service technology combined with mobile devices and relevant technologies to support an m-Learning platform which is mobile, collaboratively, resource can be effectively managed and shared. TME GAIA is used as grid engine to implement the platform. In the experiment, English learning objects followed the SCORM standard were produced with access to learn via Nokia 7210 mobile phone.
