Collaborative Project: To Enhance the Depth, Breadth, and Quality of the Collections of the Digital Library for Earth Systems Education (DLESE)

该项目由四项任务组成，旨在提高地球系统教育数字图书馆(DLESE)的广度、深度和质量：第一项任务是对藏书进行评估，通过在DLESE发现系统上的搜索、社区会议和DLESE范围声明，系统地比较实际DLESE藏书的范围和平衡与DLESE社区所希望的藏书。对于现有的收集，正在汇编关于学习背景(年级)、专题、学习资源类型、用户费用、侧重于特定地点的资源的地理分布以及侧重于特定地质时间的资源的时间分布的数据。对于“期望的收藏”，是指根据通过Discovery系统提出的搜索和浏览请求编辑的数据区。记录和比较现有集合和所需集合随时间的变化。第二项任务是在先前NSF奖的基础上再接再厉，支持地球和环境科学领域的资源收集工作，以建立一个初学者收藏，其中至少有几个资源是广泛的潜在DLESE用户感兴趣的。收集藏品的工作是由藏品评估指导的，重点是填补藏品中已查明的空白或薄点，力求避免只在特定利益集团收集的那些领域丰富的“凹凸不平”的收藏。第三项任务是资源编目，由负责地球科学专业文献GeoRef编目的小组完成。第四项任务是进一步发展和实施社区审查制度。DLESE社区评论系统向与学习者一起使用资源的教育工作者征求基于网络的反馈，并将其与专家评论相结合，以根据一套七个选择标准来评估资源。评论收藏的范围和广度正在增加，评论收藏资源正在展示。基于审查过程中收集的信息的索引正在与潜在的资源用户共享，以及用户贡献的编辑评论和教学技巧，通过NSDL风格的“注释服务”。除了建立DLESE馆藏，该项目还在馆藏开发实践和研究的几个领域为更广泛的NSDL做出贡献：数字世界中的馆藏评估方法，将馆藏评估纳入数字图书馆评估，确定在挑战和学习和教学情况下被证明有效的资源，实施基于社区的审查系统，以及使用注释系统传播有关教育资源的信息。国家科学基金会地球科学局的地球科学司正在为该项目提供大量共同资金，以认识到这种收集和相关活动对K-12教师和本科生教师的重要性。

This project consists of four tasks aimed at improving the breadth, depth and quality of the Digital Library for Earth System Education (DLESE): The first task is an assessment of the collections and is being done by systematically comparing the scope and balance of the actual DLESE Collection with the collection desired by the DLESE community, as expressed through searches on the DLESE Discovery system, in community meetings, and through the DLESE Scope statement. For the existing collection, data are being compiled on learning context (grade level), topic, type of learning resource, cost to user, geographic distribution of resources focusing on a particular locality, and temporal distribution of resources focusing on a particular slice of geologic time. For the "desired collection," data area being compiled on search and browse requests made through the Discovery System. Changes over time of both the existing collection and the desired collection are being documented and compared. The second task is building on a prior NSF award supporting a resource gathering effort in Earth and environmental science to build a starter-collection with at least a few resources of interest to a wide range of potential DLESE users. This collections gathering effort is guided by the Collections Assessment, focusing on filling identified gaps or thin spots in the collection, seeking to avoid a "lumpy" collection rich only in those areas collected by specific interest groups. The third task is the cataloging of resources and is being done by the group responsible for the GeoRef catalog of professional literature in the geosciences. The fourth task is the further development and implementation of the Community Review System. The DLESE Community Review System solicits web-based feedback from educators who have used the resource with their learners, and combines it with expert reviews to evaluate resources against a set of seven selection criteria. The scope and breadth of the Reviewed Collection is increasing and Reviewed Collection resources are being showcased. Indices based on information gathered during the review process are being shared with potential resource users, along with editor's comments and teaching tips contributed by users, via an NSDL-style "annotation service." In addition to building the DLESE Collection, this project is contributing to the broader NSDL in several areas of collection development practice and research: methodologies for collections assessment in a digital world, incorporation of collections assessment into digital library evaluation, identification of resources proven effective in challenging and learning and teaching situations, implementation of a community-based review system, and use of an annotation system to disseminate information about educational resources. Significant co-funding of this project is being provided by the Division of Earth Sciences in the NSF Directorate for Geosciences in recognition of the importance that this collection and related activities have for K-12 teachers and undergraduate faculty.
