隨著近幾年網路的普及 ，人們的學習方式有了很大的改變 ，從書本式學習進而轉變成數位學習模式 ，近年來更出現了Flipped Classroom 、MOOC(Massive Open Online Course)等創新學習模式 ，其中MOOCs為現今最廣為人知並且具有代表性的數位學習模式 ，知名的MOOCs平台網站包括edX 、Coursera 、Udacity和Google Course Builder等等 ，面對這麼多種的課程平台不禁讓人對教材的重複使用感到困擾，所以ELO的概念和它跟彼此課程平台的課程包的轉換機制就此產生 。
此篇論文中我們提出了Exchangeable Learning Object(ELO)和Google Course Builder課程之間的轉換機制並且實作出轉換工具 ，ELO為一新定義出的學習物件(Learning Object) ，它的概念是獨一無二 ，目的在於設計將edX 、SCORM 、Google Course Builder三者間的課程互相轉換 ，並且將數位學習的內容做單元式的分解和組成和重複利用 ，以節省編教材的時間 ，關於ELO的規格定義會在第三章第一節提到 。
在論文中將轉換工具 、編輯工具與共通儲存庫整合後提供更好的ELO創作工具 ，使用者可以在上面轉換課程包並使用ELO viewer觀看ELO的內容和編輯ELO和metadata ，上面也提供可以跟社群網路互動的功能 。最後在本篇論文的技術也一樣可以運用在ELO跟不同MOOCs平台上的課程轉換 。

With the current popularity of network technology, the way of learning changes dramatically from book learning into e-learning. In recent years, Flipped Classroom, MOOC (Massive Open Online Course) and other learning mode are becoming the innovative study type; MOOC is for today’s most well-known and representative e-learning model among them. Facing variety of popular MOOC platforms such as edX, Coursera, Udacity, Google Course Builder (GCB), people may confuse the reusability of course materials, the concept of ELO, therefore, was generated.
The aim of this paper is to propose a mechanism to implement a conversion tool to exchange learning objects (LOs) between GCB and Exchangeable Learning Objects (ELO). We define a new LO which is called ELO. It focuses on the design of an exchangeable mechanism between edX, SCORM and GCB, serving as an atomic object for authoring tools to compose and decompose e-Learning contents. The specification of ELO is discussed in part one of section 3. Conversion tool is integrated to a common repository infrastructure for exchanging ELOs, providing a better authoring tool that allows users to covert or edit course packages. In addition, Authoring tool further includes functions for social community interactions, viewing ELO and editing metadata. Finally, the technical contribution of this paper can be used to exchange LOs between different MOOCs platforms.
