The main objectives of this two-year project are to build a functioning digital library of reusable instructional and learning materials for undergraduate level science and to use the library as a testbed to address several important research issues in the evolution and use of digital libraries. The project represents a collaboration between the COLLEGIS Research Institute (CRI), the Instructional Management System (IMS) Project, the University of North Carolina at Wilmington (UNCW), the ACM SIGGRAPH Education Committee's Digital Library (SECDL), the institutions that comprise the Computer Science Teaching Center (CSTC), and EDUCAUSE. The library content includes diverse undergraduate science-education resources coming initially from the members of the collaboration. The high quality digital resources provided by these groups range from primary source materials, such as datasets and images, to Java applets and visualization tools, to complex simulations and structured curriculum fragments. They also span a wide range of subjects from Earth sciences to pure mathematics. The library is adopting the IMS standards being created to represent instructional and learning materials in a platform-independent, reusable way. Specifically, library content is being described using IMS metadata to provide a testbed for the IMS standards. The IMS metadata is being extended as necessary to cover the diverse material being tagged. The main tasks of the project are to construct an initial version of the library, called XXDL, to incorporate the diverse content of the project partners into the library, to establish the procedures by which the resources are catalogued and reviewed independently, and to grow the library user community. The main tasks of the second year include a broad evaluation of the effectiveness of the XXDL and a more focused investigation of the roles, costs, and benefits of using the standardized IMS metadata for tagging the data. The expectation is that IMS should provide superior indexing because it has been designed expressly to characterize instructional and learning content and because the use of standards should ensure that all content catalogers apply a uniform descriptive schema to diverse learning resources. It is anticipated that XXDL users will benefit by having powerful and predictable tools with which to find appropriate learning and instructional materials. In addition to providing a "stress test" of the IMS metadata, the project should have several additional broad impacts. It directly benefits undergraduate science faculty who use the library to develop improved digital course materials. It also helps faculty to create collaborative communities to share and reuse learning resources. The evaluation of XXDL helps library developers understand how to design more effective digital libraries and online communities that encourage reuse of learning materials and collaboration. The XXDL testbed can be used for future focused investigations of digital library issues.

这个为期两年的项目的主要目标是建立一个可重复使用的教学和学习材料的数字图书馆，用于本科级别的科学，并将图书馆用作测试台，以解决数字图书馆进化和使用中的几个重要研究问题。 该项目代表了Collegis Research Institute（CRI），教学管理系统（IMS）项目，北卡罗来纳大学威尔明顿大学（UNCW），ACM Siggraph教育委员会数字图书馆（SECDL），构成计算机科学教学中心（CSTC）和教育的机构。 图书馆的内容包括最初来自合作成员的各种本科科学教育资源。 这些组提供的高质量数字资源范围从数据集和图像等主要源材料到Java Applet和可视化工具，再到复杂的模拟和结构化课程片段。 它们还跨越了从地球科学到纯数学的广泛主题。 该图书馆采用正在创建的IM标准来以与平台无关的，可重复使用的方式表示教学和学习材料。 具体而言，正在使用IMS元数据来描述库内容，以为IMS标准提供测试台。 IMS元数据正在必要时扩展，以覆盖被标记的各种材料。 该项目的主要任务是构建名为XXDL的库的初始版本，以将项目合作伙伴的各种内容纳入图书馆，以建立对资源进行分类和独立审查的过程，并建立图书馆用户社区。 第二年的主要任务包括对XXDL有效性的广泛评估以及对使用标准化的IMS元数据对数据进行标记的角色，成本和收益的更为集中研究。期望IMS应该提供卓越的索引，因为它的设计是为了表征教学和学习内容的特征，并且使用标准应确保所有内容核对器都将所有内容策略器应用于多样化的学习资源。 可以预期，XXDL用户将通过拥有适当的学习和教学材料的功能强大且可预测的工具来受益。除了提供IMS元数据的“压力测试”外，该项目还应具有更多的广泛影响。 它直接使使用图书馆开发改进的数字课程材料的本科科学教师受益。 它还有助于教师创建协作社区，以共享和重复学习学习资源。 XXDL的评估可帮助图书馆开发人员了解如何设计更有效的数字图书馆和在线社区，以鼓励重新使用学习材料和协作。 XXDL测试床可用于对数字图书馆问题的未来重点调查。
