SCORM(Sharable Content Object Reference Model)是近年來深具規模的遠距教學標準規格。1999年由美國國防部支持的ADL先導計畫在發展SCORM規格時，即以朝向課程能再使用，共享，持久，以及跨平台等特性，提供共同統一的介面讓教材能廣域的流通在世界的每個角落。 本篇論文主要是實作一個符合SCORM 2004的學習執行環境，符合SCORM標準的課程都能夠上傳至學習執行環境上並且學習，更利用了Web Service的技術來實作學習執行環境的部份功能以支援不同的行動學習裝置，減少相同的功能要重覆撰寫，例如SCORM 1.3版最重要的特色-教學活動順序規則(Sequencing)、學習者選課、註冊課程、上下傳課程等等功能。 A good e-learning standard help e-learning operation efficiently, learning content sharable, and provide learning activity properly. ADL proposed SCORM (Sharable Content Object Reference Model) in 1997, it provided durability, interoperability, accessibility and reusability. SCORM version 1.2 defines Run-Time environment , metadata, content aggregation, and data model to support E-learning. In SCORM version 1.3, it included IMS Simple Sequence standard to achieve flexible learning activity. However, the sequence engine part of a RTE are complex and hard to implement. There are Many non standard based RTEs. Even Standard based RTEs still have some issues, such as Versioning、Language dependent、Platform dependent. We follow a good e-learning standard—SCORM and implement a SCORM compliant RTE. In order to provide some Language dependent functions, we develop these functions by Web Service. Base on .Net framework to build the proposed Web Service. Those functions can be use between RTE and the other learning devices, such as PDA、Smartphone、Hyperpen.
