Completing the NSDL Strand Map Service: Content Coverage and NDR Integration

这个NSDL基因图谱服务（SMS）项目将科学素养地图集第1卷到第2卷的基因图谱绘制的过去的成功扩展到了第2卷，该地图集于2007年3月由美国科学促进会（AAAS）出版。该项目还扩大了科学内容标准的覆盖范围，通过使用成就标准网络对内容进行建模，将这些地图与美国科学促进会2061项目基准标准的当前映射连接到国家科学教育标准。这项工作为K-12的学习者和教育工作者提供了与AAAS基准和Strand地图完整集合相关联的教学材料的完整访问。SMS被部署到NDR （http://strandmaps.nsdl.org/）中，维护工具正在开发中，以支持在本授权的执行期限之外对AAAS基准存储库的任何必要更新。这种创新的信息模型提供了丰富的科学学习目标描述，超越了学习目标的简单文本描述，包括学习目标之间的关键关系、常见的学生概念和相关的教育研究等教学上的重要信息。

This NSDL Strand Map Service (SMS) project is extending the past success of strand mapping the Atlas of Science Literacy Volume 1 to Volume 2 of the Atlas, published in March 2007 by the American Association for the Advancement of Science (AAAS). The project is also broadening science content standards coverage by modeling the content using the Achievement Standards Network to connect the maps to National Science Education Standards based on their current mappings to AAAS Project 2061 Benchmark Standards. This effort is providing K-12 learners and educators with full access to instructional materials that are linked to the complete collection of AAAS Benchmarks and Strand Maps. The SMS is deployed into the NDR (http://strandmaps.nsdl.org/) and maintenance tools are being developed to support any necessary updates to the AAAS Benchmarks Repository beyond the performance period of this grant. This innovative information model provides rich descriptions of science learning goals that go beyond plain text descriptions of learning objectives by including pedagogically important information such as the critical relationships between learning goals, common student conceptions and relevant education research.
