Enriching American Science Education and Global Understanding Through New Technologies

9350523 RIDD环境数据在全球范围内的供应不断增加，先进而廉价的计算机硬件的供应，以及用户友好、灵活的软件的开发，使开发能够使学生从所在地区到整个世界的任何规模接触世界的模块成为可能。许多国家和国际组织都建立了网络，致力于收集和分享越来越多的地球环境数据。人们越来越意识到全球变化和环境压力，以及人类对这些条件及其改善负有的责任。学生可以也应该成为以新的方式探索这些问题的一部分。通过动手操作、图像分析和地理信息系统(GIS)数字地图处理，中学生可以覆盖遥感数据，以查看人与自然世界之间的界面上的重要关系。在这一试点项目中，制定了为期两周的两个单元：一个是从全球的角度来看，如取消认证或热带砍伐森林；另一个是关于当地条件，如用水。这些模块由教师、科学教育工作者和科学家共同开发，并在不同地点进行现场测试。该软件运行在一台386同等的计算机上，具有足够的内存来容纳ArcView文件和4MB的RAM。该项目由一个国家咨询委员会管理，并有两名外部评估员记录对学生和教师的影响。***

9350523 Ridd A growing world-wide supply of environmental data, the availability of sophisticated and inexpensive computer-based hardware, and the development of user-friendly, flexible software makes possible the development of modules which can put students in touch with the world at any scale from the locality of the student to the world at large. Many national and international organizations are networked and committed to collecting and sharing increasing volumes of Earth-environmental data. There is a growing awareness of global change and environmental stress and the responsibility humans have for these conditions and their amelioration. Students can and should be part of the quest to explore these questions in new ways. Through hands-on, image analysis and Geographic Information Systems (GIS) digital map manipulation, secondary school students can overlay remote-sensed data to see vital relations at the interface between humans and the natural world. Two modules, of two weeks duration, are developed in this pilot project: One is global in perspective such as decertification or tropical deforestation; the other concerns local conditions such as water use. The modules are developed by teachers, science educators and scientists working together and are field tested in diverse locations. The software runs on a 386 equivalent computer with enough memory to accommodate ArcView files and 4 MB of RAM. The project is governed by a national advisory board and has two external evaluators to document the effects on students and teachers. ***
