OLEO: The On-Line Educational Observatory

天文学(11)项目CLEA(当代天文学实验室体验)正在开发一个在线环境，为天文学研究生提供基于发现的实验室练习。该系统的组成部分是：(1)基于浏览器的在线教育观测站(OLEO)，它逼真地模拟光学、无线电和天基望远镜，以及光度、光谱和成像仪器。(2)覆盖整个天空的广泛的试探性数据库，其中包括关于各种真实天文天体的位置、星等、光谱和其他性质的选定数据，其中包括小行星、恒星、星系、脉冲星、X射线和红外源。(3)使用虚拟教育观察站的各种练习的学生练习册和教师指南。CLEA材料可在专门的Oleo网站上获得，也可在一系列CD-Rom上安装在镜像站点、本地网络和个人机器上。在国家和区域教师会议上举办的外联讲习班为材料的使用提供了支持。2003年夏天，将在葛底斯堡学院校园举办大学教师暑期培训班。这些材料的课程影响和教学效果正在AdiVerse机构集团(大学、四年制学院、两年制学院和高中)通过外部评估者的观察和在线问卷分析进行评估。

Astronomy (11) Project CLEA (Contemporary Laboratory Experiences in Astronomy) is developingan on-line environment that provides discovery-based laboratory exercises toundergraduate astronomy students. The components of the system are: (1) Abrowser-based On-Line Educational Observatory (OLEO) which realisticallysimulates optical, radio, and space-based telescopes, along with photometric,spectroscopic, and imaging instruments,. (2) An extensive heuristic database, coveringthe entire sky, which incorporates selected data on positions, magnitudes, spectra, andother properties of a wide range of real astronomical objects including asteroids, stars,galaxies, pulsars, x-ray and IR sources. (3) Student workbooks and teacher's guides for avariety of exercises using the Virtual Educational Observatory.CLEA materials are made available on a dedicated OLEO Website, as well ason a series of CD-ROMS for installation on mirror sites, local networks, and individualmachines. The use of the materials is supported by outreach workshops held atnational and regional teachers' meetings. A summer training workshop for collegeteachers will be held on the Gettysburg College campus in the summer of 2003. Thecurricular impact and pedagogical effectiveness of these materials is being evaluated at adiverse group of institutions (Universities, 4-year colleges, 2-year colleges, and HighSchools), by observations by an external evaluator and through the analysis of on-linequestionnaires.
