On-Line Exploratory Learning Resources for Undergraduate Astronomy and Physics

天文学（11）该项目正在制作三种类型的探索性产品，以加强大学生天文学和物理学的在线互动学习：更新现有的介绍天文学的在线超文本，并通过增加一个定量层来增强它，通过该定量层，学生可以探索文本顶层中描述的现象的基础物理;2.开发小应用程序，学生可以探索物理和天体物理现象，类似于那些已经开发;和3。开发和实地测试几个在线学习模块，引导学生探索和理解小程序所说明的物理现象，沿着已经开发为原型的“Planetfinder”学习模块的路线。智力优势：拟议的项目都引导学生理解当前天体物理学研究中一些最活跃领域的物理基础。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，以改善学生的学习和参与。更广泛的影响：正在制作的资源可作为出版商提供在线学习资源的类似努力的原型。此外，这些资源经过适当修改，对中学和天文馆和科学博物馆等非正式学习环境中的学习很有用。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.
