National Digital Library for Undergraduate Mathematics, Science, and Technology Teacher Preparation and Professional Development

该项目正在创建一个国家虚拟教师资源中心（NVTRC），该中心的重点是为两年制和四年制文理学院和教育学院教授科学和数学本科课程的教师提供资源集合。NVTRC是俄亥俄州立大学和艾森豪威尔国家信息交换中心之间的合作，它有望成为数学、科学和技术本科教师教育和专业发展的中心和焦点。NVTRC的收藏主要集中于电子资源，包括基于网络的文本或数据资源、软件或视频，可通过网络或其他电子手段下载，或其他新兴技术应用。正在建立一个审查程序，以确保资源准确，教学有效，并确保NVTRC作为优质材料的有效来源运作。此外，NVTRC工作人员在特定级别或“粒度”上识别电子材料，这是其他网络搜索机制通常不支持的。最后，我们为NVTRC的用户提供一系列数码和人性化服务，包括通过有效的索引和链接随时发现和检索资料和资料信息，用户或第三方评论/奖励与馆藏中的项目相关联，用户注册额外服务，如电子邮件通知新资源，以及真实和虚拟参考咨询台服务。

This project is creating a National Virtual Teacher Resource Center (NVTRC) that focuses on a collection of resources for two-year and four-year Colleges of Arts and Sciences and Colleges of Education faculty members who teach science and mathematics undergraduate courses. The NVTRC is a collaboration between the Ohio State University and the Eisenhower National Clearinghouse, and it expects to serve as a hub and focal point for mathematics, science, and technology undergraduate teacher education and professional development. The collection of the NVTRC focuses primarily on electronic resources including web-based text or data resources, software or video that can be downloaded via the web or other electronic means, or other emerging technology applications. A review process is being established to ensure that the resources are accurate, pedagogically effective, and that the NVTRC operates as an efficient source of quality materials. Additionally, the NVTRC staff identifies electronic materials at a level of specificity or "granularity" not often supported by other web searching mechanisms. Finally, a range of digital and human services are offered to users of the NVTRC including ready discovery and retrieval of materials and information about materials through effective indexing and linking, user or third-party reviews/awards linked to items in the collection, user registration for additional services such as email notification of new resources, and real and virtual reference desk services.
