Building learning objects with information object model

With the rapid growth of network technologies, Web-based learning conquers the limits of time and location in traditional teaching and is increasing its popularity. However, most of the learning websites lacks of the convenient tools in packaging the information users are interested in. Therefore, the information posted and exchanged in the websites is not easy to be extracted and reused somewhere else. An information object is a basic information entity which includes the required data and methods to manipulate the data or the needed operations for the entity. In this paper, we apply the information object model to build a learning object sharing system for HTML5. Traditionally, a learning object is a collection of content items, practice items, and assessment items that are combined based on a single learning topic. The learning objects we developed have the merits of portability and extensibility in system structure. We will describe the basic concept of the learning objects we propose, and the design of the prototype system developed on the Web system.
