Abstract

The IMS content packaging specification provides a framework for deploying learning content based on an XML data structure known as a manifest. A content package is described by metadata and optionally incorporates IMS simple sequencing rules and an IMS learning design, both of which are hard-coded when the package is created. Though these provide some measure of adaptation, the paths through the learning material are pre-determined at design time and it is clear that the current specifications are not robust enough to support the kind of adaptation that caters to the need of all types of learners. In this paper, we propose that Web services can be used to support the dynamic adaptation of content for different learners based on the content packaging specification. We identify the kinds of Web services that would be useful and explain how these services are connected to content packages of reusable online resources. We also discuss the role of pedagogical agents in accessing Web services on behalf of a learner.
使用Web服务动态地重新利用可重用的在线学习资源
IMS内容打包规范提供了一个框架,用于基于称为清单的XML数据结构部署学习内容。内容包由元数据描述,并可选择合并IMS简单排序规则和IMS学习设计,这两者在创建包时都是硬编码的。虽然这些提供了一些适应措施,但通过学习材料的路径是在设计时预先确定的,很明显,当前的规范不够健壮,无法支持满足所有类型学习者需求的适应。在本文中,我们提出可以使用Web服务来支持基于内容打包规范的不同学习者对内容的动态适应。我们确定了有用的Web服务类型,并解释了这些服务如何连接到可重用在线资源的内容包。我们还讨论了教学代理在代表学习者访问Web服务中的作用。
