On-Line Exploratory Learning Resources for Undergraduate Astronomy and Physics

天文学（11）该项目正在生产三种探索性产品，以加强本科天文学和物理学的在线互动学习：1 .更新现有的在线天文学介绍超文本，并增加一个定量层，使学生能够探索文本顶层所描述现象的底层物理；开发小程序，让学生可以探索物理和天体物理现象，类似于那些已经开发的；说谎。开发和实地测试几个在线学习模块，指导学生探索和理解由小程序说明的物理现象，沿着已经开发为原型的“行星发现者”学习模块的路线。智力优势：所有被提议的项目都将引导学生了解当前天体物理学研究中一些最活跃领域的物理学基础。此外，PI正在开展研究，继续学习如何最好地将在线学习设施纳入天文学和物理学入门课程，以提高学生的学习和参与度。更广泛的影响：正在制作的资源为出版商提供在线学习资源的类似努力提供了原型。此外，这些资源经过适当修改后，对中学和诸如天文馆和科学博物馆等非正式学习环境的学习是有用的。因此，该项目正在修改和实地测试这些场地的一些资源。

Astronomy (11) The project is producing three types of exploratory products to enhance on-line interactive learning in undergraduate astronomy and physics:1. Updating an existing on-line hypertext of introductory astronomy and augmenting it by adding a quantitative layer by which the students can explore the underlying physics of the phenomena described in the top layer of the text;2. Developing applets by which students can explore physical and astrophysical phenomena, similar to those already developed; and3. Developing and field-testing several on-line learning modules that guide students to explore and understand physical phenomena illustrated by the applets, along the lines of the "Planetfinder" learning module that has already been developed as a prototype.Intellectual Merit: The proposed projects all lead students to an understanding of the physics underlying some of the most active areas of current research in astrophysics. Moreover, the PI is carrying out research to continue to learn how best to incorporate online learning facilities in introductory astronomy and physics courses to improve student learning and engagement.Broader Impacts: The resources that are being produced serve as prototypes for similar efforts by publishers to provide on-line learning resources. Moreover, the resources, suitably modified, are useful for learning in secondary schools and in informal learning environments such as planetariums and science museums. Therefore, the project is modifying and field-testing a few of the resources in those venues.
