Project CLEA: Contemporary Laboratory Experiences in Astronomy

该项目正在继续为入门天文学实验室开发一系列实验室单元。这些模块解决了现代化的迫切需求：尽管天文学对本科生来说是一门非常受欢迎的课程，对于许多人来说，这是他们第一次也是唯一的大学科学经验，但天文学实验室很难提供必要的实践经验，因为天文物体的模糊，许多现象的不便时间尺度，以及变化无常的天气。过去，天文学教员可以使用的大多数练习都依赖于对照片或存储的数据的分析，并举例说明了日益过时的技术。目前的项目，当代天文学实验室经验(CLEA)，已经开发了7个Windows和Mac练习，并将在1996年至少完成3个。每个模块都包括软件、学生指南、教师手册和技术文档。这些材料已经被引入葛底斯堡学院的课堂，并被广泛分发。Clea软件目前在全美和40个外国使用，每年至少有1万名学生使用。四个Clea练习获得了1994年计算机物理教育软件奖。目前的项目正在继续开发模块，并评估模块对学生学习的效果。

The project is continuing to develop a series of laboratory modules for the introductory astronomy laboratory. The modules address a pressing need for modernization: though astronomy is a very popular course for undergraduates, and for many their first and only college experience in science, laboratories in astronomy have difficulty providing needed hands-on experience because of the faintness of astronomical objects, the inconvenient time scale of many phenomena, and the fickleness of weather. In the past, most exercises available to astronomy instructors relied on analysis of photographs or canned data, and exemplified techniques that were increasingly out-of-date. The current project, Contemporary Laboratory Experiences in Astronomy (CLEA), has already developed 7 Windows and Mac exercises, and will complete at least 3 more by 1996. Each module consists of software, student guides, teachers' manuals, and technical documentation. The material has been introduced into classes at Gettysburg College and distributed widely. CLEA software is currently at use throughout all the United States and 40 foreign countries, reaching at least 10,000 students per year. Four CLEA exercises won the 1994 COMPUTERS IN PHYSICS educational software prize. The current project is continuing to develop modules and evaluating the effectiveness of modules on student learning.
