A Digital IdeaKeeper For K-12: NSDL Scaffolded Portal Services for Information Analysis and Synthesis

虽然AAAS和NRC等国家组织可以呼吁K-12学生开展科学探究活动，但必须为学生提供这种具有挑战性的智力活动的支持。数字图书馆，如国家科学、技术、工程和数学教育数字图书馆(NSDL)，通过允许学生访问一系列科学信息和资源：网站、数据集、图像等，可以成为科学探究的重要组成部分。在现实中，符合NSDL标准的数字图书馆必须超越支持学生查找信息的简单服务，还必须提供脚手架服务，以支持学生分析和综合他们在搜索中找到的信息，涉及他们在科学探究项目中调查的驱动问题。该项目满足以下需求：(1)设计和构建IdeaKeeper，这是一个专门为K-12科学学习者提供的脚手架NSDL门户和服务，以及(2)在底特律中学教室部署IdeaKeeper版本，以评估这种支持性数字图书馆服务对学习的影响。IdeaKeeper整合了脚手架或软件功能，以支持学生分析图书馆资源，并将信息合成为论点，解决他们的驾驶问题。通过将IdeaKeeper纳入科学课程单元，IdeaKeeper经过课堂测试，以评估分析/合成支架的有效性，并阐明新的支架和能力，以扩展当前以学习者为中心的数字图书馆项目。因此，IdeaKeeper项目的影响包括：-专门的IdeaKeeper门户和相关服务，作为NSDL的组件，供其他学习者使用，其他研究人员使用新功能和支架进行扩展。-演示符合NSDL标准的一套服务如何真正支持K-12科学学习。IdeaKeeper支架和功能的影响是根据它们对学生进行信息分析/合成的支持程度以及学生对信息分析/合成的了解程度来评估和阐述的。-IdeaKeeper项目是一个路标，说明还需要哪些新服务来更有效地支持K-12科学研究和科学学习。

While national organizations such as the AAAS and the NRC can call for K-12 students to carry out science inquiry activities, students must be provided with supports for such challenging intellectual activity. Digital libraries, such as the National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) can be a vital part of science inquiry by giving students access to range of scientific information and resources: websites, data sets, images, etc. In reality, NSDL-compliant digital libraries, in particular, must go beyond simply services that support students in finding information and also provide scaffolded services to support students in analyzing and synthesizing the information they find in their searches with respect to the driving questions they are investigating in their science inquiry projects. This project addresses the needs to (1) design and build the IdeaKeeper, a specialized scaffolded NSDL portal and services for K-12 science learners and (2) deploy versions of IdeaKeeper in Detroit middle school classrooms to assess the impact of such supportive digital library services on learning. IdeaKeeper incorporates scaffolds, or software features to support students in analyzing library resources and synthesizing the information into arguments addressing their driving questions. By incorporating IdeaKeeper into science curriculum units, IdeaKeeper is classroom-tested to assess the effectiveness of the analysis/synthesis scaffolds and to articulate new scaffolds and capabilities extending current learner-centered digital library projects. Thus the impact of the IdeaKeeper project includes: - the specialized IdeaKeeper portal and associated services as components for the NSDL for other learners to use and other researchers to extend with new functionalities and scaffolds. - the demonstration of how an NSDL-compliant set of services can indeed support K-12 science learning. The impact of the IdeaKeeper scaffolds and functionality is assessed and articulated in terms of how well they support students in doing information analysis/synthesis and how much students learn about information analysis/synthesis. - the IdeaKeeper project acts as a guidepost to what new services are still needed to more effectively support science inquiry and science learning in K-12.
