CoMPASS-DL: Design and use of a concept map interface for helping middle school students navigate digital libraries

该项目解决了在数字图书馆（如国家科学数字图书馆（NSDL））内为学生提供更好的机制以查找信息的需要。先前的研究在超文本系统的设计和认知点使用图形辅助工具，以帮助导航和学习;和教育心理学研究表明，概念图的价值，以支持科学现象和原则之间的丰富关系的学习。因此，该项目以概念图的形式使用概念联系，使学生能够探索问题并遵循自己的路径。为了实现这一目标，CoMPASS-DL系统正在开发一个界面，提供可导航的概念图，帮助学生选择资源的基础上的文档相互之间的相关性，以及学生的目标。 CoMPASS-DL正在威斯康星州的中学使用，以了解数字图书馆在课堂学习中的影响。该项目还使为K-12学生设计资源的NSDL社区成员能够更好地了解如何将数字资源整合到基于探究的科学课程中。

This project addresses the need to provide students with better mechanisms within digital libraries, such as the National Science Digital Library (NSDL), to find information. Prior research in the design and cognition of hypertext systems points to the use of graphical aids to help navigation and learning; and educational psychology research shows the value of concept maps to support learning of rich relationships between science phenomena and principles. The project, therefore, is using conceptual linking in the form of concept maps to enable students to explore questions and follow their own paths. To achieve this aim, the CoMPASS-DL system is being developed with an interface that provides navigable concept maps that helps students to select resources based on the relatedness of the documents to each other as well as to students' goals. CoMPASS-DL is being used in middle schools in Wisconsin to understand the impact of digital libraries in classroom learning. The project also enables NSDL community members who are designing resources for K-12 students to better understand how digital resources can be integrated in inquiry-based science classes.
