Harvard-Smithsonian Digital Video Library

这个收集项目正在收集和管理由哈佛-史密森天体物理中心制作的大量STEM数字视频材料。该中心支持STEM教育改革的数字视频材料收集是在过去15年中开发的，耗资约1,500万美元，其中包括著名电视节目的原始材料，如A Private UNIVESE，以及为Annenberg/CPB制作的专业发展材料。这些资料包括大约3500个小时的录像片段，以数字形式存档，并通过一个可搜索的数据库编制索引。这套材料涵盖了各种主题和格式，包括高质量的案例研究镜头，展示了实践教学，罕见的和难以创建的材料，记录儿童在科学和数学方面的想法，对STEM学习的国际知名研究人员的采访，以及计算机动画和其他昂贵的STEM想法的可视化。该项目正在建立一个350小时的数字视频材料图书馆，支持STEM教育，将通过NSD提供。项目人员正在审查整个收藏，以寻找支持基于标准的学习的有价值的材料。正在根据这些标准的适用性对适当的材料进行标记，收集的资料正在被挑选到一个可管理和有用的大小，并进行分类，以便教师和教师教育工作者能够根据STEM学科、年龄水平或内容领域来搜索收集的资料。该项目正在使这些材料在网络平台上广泛使用，同时将全分辨率母版存档为哈佛图书馆的一部分。网络界面将集合链接到NRC国家科学教育标准、AAAS基准以及州和地方标准。该项目正在与NSDL核心集成计划的顾问合作，以确保元数据和格式符合NSDL的相关工作。它还为在教育中使用视频铺平了道路，同时为教育工作者提供了广泛的获取支持STEM教育改革的重要材料的机会。NSF数学和物理科学局的多学科活动办公室正在为该项目提供大量共同资金，以认识到这种关于科学学习性质的数字视频资源的收集对K-12教师和本科教师的重要性。

This Collections project is assembling and managing an extensive collection of STEM digital video materials produced by the Harvard-Smithsonian Center for Astrophysics. The Center's collection of digital video materials supporting STEM education reform has been developed over the past decade and a half at a cost of some $15 million, and includes source materials for well-known television programs such as A PRIVATE UNIVESE along with professional development materials created for Annenberg/CPB. The collection consists of some 3,500 hours of video footage, archived in digital form and indexed through a searchable database. Materials in this collection span a variety of topics and formats and include high-quality, case-study footage showing teaching in action, rare and difficult to create materials documenting children's ideas in science and math, interviews with internationally prominent researchers in STEM learning, and computer animations and other costly visualizations of STEM ideas. This project is establishing a library of 350 hours of digital video materials supporting STEM education that will be available through the NSDL.Project personnel are reviewing the entire collection for materials of value in supporting standards-based learning. Appropriate materials are being tagged according to their applicability to these standards, the collection is being culled to a manageable and useful size, and catalogued so teachers and teacher educators are able to search the collection by STEM discipline, age level, or content area. The project is making these materials broadly accessible on a web platform while archiving a full-resolution master copy as part of the Harvard Library. The web interface is linking the collection to NRC National Science Education Standards, AAAS Benchmarks, and state and local standards. The project is working with advisors from the NSDL Core Integration program to ensure metadata and formats conform to related efforts of the NSDL. It is also paving the way for the use of video in education while providing educators broad access to vital materials supporting STEM education reform. Significant co-funding of this project is being provided by the Office of Multidisciplinary Activities in the NSF Directorate for Mathematical and Physical Sciences in recognition of the importance that this collection of digital video resources on the nature of science learning has for K-12 teachers and undergraduate faculty.
