Earth Systems Science (40)The goal of this project is to improve the quality of education by providing educators with instant access to pedagogical content knowledge (PCK) as they prepare to teach a given topic or lesson using resources from a digital library. The project links digital library resources with annotations that represent one of three types of PCK: (a) resources that deal with teaching a specific skill or science process, (b) resources that deal with common misconceptions about a specific concept, and (c) resources that deal with an assessment technique. From the user's perspective, PCK annotations will mean that when a digital library search engine returns a resource description, it may include extra links for related pedagogical materials that can be useful when trying to teach with that science resource. The testbed for this project is the Digital Library for Earth System Education (DLESE). Over the period of the grant the plan is to provide PCK annotations for at least one thousand of the resources in DLESE. The project is also refining the DLESE user interfaces so that annotations are effectively displayed as part of search results. The new user interface for the display of annotations is being subjected to usability testing, and once the pedagogical annotations are available in the public DLESE, their use in practice will be monitored. Although initial testing is being done with DLESE, the work has broader impact since the annotation metadata will be harvestable NSDL and other digital libraries. NSDL can also adapt the tools and methodology developed by this project to add pedagogical annotations to its own collections. The need for relevant, just-in-time pedagogical content knowledge, to support better-targeted teaching and more-effective learning, is common across the full sweep of disciplines covered by NSDL.

地球系统科学（40）该项目的目标是通过为教育工作者提供即时访问教学内容知识（PCK）的机会来提高教育质量，因为他们准备使用数字图书馆的资源教授给定的主题或课程。 该项目将数字图书馆资源与代表三种类型的PCK之一的注释联系起来：（a）处理教学特定技能或科学过程的资源，（B）处理关于特定概念的常见误解的资源，以及（c）处理评估技术的资源。 从用户的角度来看，PCK注释将意味着当数字图书馆搜索引擎返回资源描述时，它可能包括相关教学材料的额外链接，这些链接在尝试使用该科学资源进行教学时可能会很有用。该项目的试验平台是地球系统教育数字图书馆（DLESE）。 在赠款期间，该计划将为DLESE中的至少一千个资源提供PCK注释。 该项目还改进了DLESE用户界面，以便将注释有效地显示为搜索结果的一部分。 正在对显示注释的新用户界面进行可用性测试，一旦在公共DLESE中提供教学注释，将监测其实际使用情况。 虽然最初的测试是用DLESE完成的，但这项工作具有更广泛的影响，因为注释元数据将是可收获的NSDL和其他数字图书馆。 NSDL还可以调整该项目开发的工具和方法，以将教学注释添加到自己的收藏中。对相关的，及时的教学内容知识的需求，以支持更有针对性的教学和更有效的学习，在NSDL涵盖的所有学科中都很常见。
