| dc.description.abstract | 論文摘要
隨著分散而獨立數位學習(e-learning)系統不斷的發展，本研究認為在未來發展極需一個具共享能力、跨Portal平台，而且能夠整合各種數位學習資源的系統。目前分散且獨立的數位學習系統所遭遇到的困難讓這些系統變得無效率。追根究底，這些困難為：數位學習系統的跨平台問題、學習物件協同操作問題、學習物件於顯示層上的整合及清晣操作存取數位學習系統的問題。本研究提供一開放式、統一及跨平台的數位學習Portal系統以解決以上關鍵困難點。
在本研究提出的架構中，使用了WSRP服務，一個經由網路服務發送顯示層內容的標準，在其餘數位學習系統發送所提供之共享學習物件內容至本研究所提供的Portal時，能夠保存共享學習物件顯示層內容；另外，本研究也使用了BPEL4WS，在各共享數位學習系統之間提供一項以任務為基礎的課程流程之編組。WSRP為一標準純顯示層通訊協定，並且不允許整合者(WSRP通訊協定中之消費者端)截取足夠的內容資料去執行適當的管理流程。
本研究將探討此缺點並提出解決方案以有效整合來自各個學習站台之學習單元顯示層內容。本研究也會以一實例展示所提出架構的重要性及可行性。 | zh_TW |
| dc.description.abstract | ABSTRACT
With the rapid advance of stand-alone e-learning systems, we believe a sharable and interoperable portal platform capable of integrating various existing learning systems is critical for the future development of e-learning systems. We identify four difficulties as the root causes for current ineffective sharing of stand-alone learning systems: interoperability of e-learning systems, collaboration of learning objects, presentation level integration of learning objects, and transparent access of e-learning systems.
In this paper, we propose an open, unified, and interoperable e-learning portal to meet this critical need. In our proposed system, we employs WSRP services, a standard for sending presentation content via web service, to preserve the presentation of shared learning objects from participating learning systems, and BPEL4WS for the task-based course workflow orchestration among shared learning systems. WSRP, as a pure presentation standard, does not allow integrators to intercept sufficient content to properly manage workflow.
We discuss this insufficiency and propose our solution in order to enable seamless integration of presentation preserved learning units from various autonomous learning sites. We also use an example to illustrate the importance and feasibility of our approach. | en_US |
