Expanding the ChemEd DL to Enhance Pedagogic Impact

化学教育数字图书馆（ChemEd DL）开发了广泛的资源和服务，包括为K-16教育水平的教师和学生提供网络化学教学材料。该项目正在确定ChemEd DL缺乏材料的领域，在这些领域增加新的资源，将单个资源合并为教师和学生可以轻松使用的更大单元，并正在开发使用其资源的最佳教育实践的教学文档。这些目标正在通过动员已经计划好的ChemEd DL研讨会的参与者来评估资源，添加新的资源，将资源组合成更大的单元，并根据这些单元描述成功的教学方法来实现。国家可持续发展图书馆的教学服务正在促进这一进程，该服务正在为在线教学材料的示范使用说明提供信息交流中心。该项目还与NSDL资源中心的STEM交流项目合作。该项目利用社会网络作为传播其开发的教学信息和资源的手段。这提高了ChemEd DL材料对教师的可发现性和实用性，从而为更多的学生带来了优秀的在线学习材料。通过改善化学教育，该项目正在提高国家科技劳动力的数量和技能。

The Chemical Education Digital Library (ChemEd DL) has developed a broad range of resources and services involving Web-delivered chemistry instructional materials for teachers and students from K-16 educational levels. This project is identifying areas where the ChemEd DL lacks materials, is adding new resources in those areas, is amalgamating individual resources into larger units that teachers and students can easily use, and is developing pedagogic documentation of best educational practices in using its resources. These goals are being achieved by mobilizing participants in already-planned ChemEd DL workshops to evaluate resources, add new ones, combine resources into larger units, and describe successful pedagogy based on those units. This process is being facilitated by the NSDL Pedagogic Service, which is providing a clearinghouse for descriptions of exemplary uses of online instructional materials. The project is also collaborating with the STEM Exchange project of the NSDL Resource Center. The project is using social networks as a means of dissemination of the pedagogic information and resources it develops. This is enhancing both discoverability and usefulness of ChemEd DL materials for teachers and hence is bringing to many more students excellent online learning materials. By improving chemistry education, the project is increasing the number and skills of the nation's scientific and technical workforce.
