Expanding the Data Cycle: Empowering Middle Level Teachers and Students to Integrate Information Technology, Data Skills and Science Content

这一建议是为了方便中学科学教师和学生使用地球系统科学数据。该项目使中学教师能够访问和分析地球科学数据集，使用数据分析工具（IT），并对其进行调整，以满足学生的兴趣和课程需求。此外，参与计划的学生亦能以有意义的方式使用地球科学数据，并学会使用资讯科技工具的技巧，为他们日后的工作提供参考。该项目利用地球探测工具书中的地球科学数据和数据分析工具制作定制的教育活动，这些活动将通过项目网站、国家科学数字图书馆（NSDL - www.nsdl.org）和地球系统教育数字图书馆（DLESE - www.dlese.org）的课堂数据使用门户网站提供给更广泛的教育界。通过在网络上使用这些工具，这些资源可以被发现，从而可供国内和国际的教师使用。该计划涉及75名中学教师，为期三年，150名中学生参加暑期讲习班，在教师与学生一起实施他们在夏季开发的活动时，整个学年有多达9000名学生参加。教师们参与了为期一年的教师专业发展项目，其中包括夏季研讨会和为期一年的在线讨论、电话会议和为期一天的会议支持。这个项目的结果将是在dese和其他地方编目的定制的数据丰富的活动，一组教师和学生将更好地准备使用地球科学数据和数据分析工具来帮助他们了解当前的社会问题。

This proposal is to facilitate middle-school science teachers and students using Earth system science data. The project provides middle-school teachers with the ability to access and analyze Earth science data sets, use data analysis tools (IT), and adapt them in a way that addresses both the interests and curricular needs of their students. It also enable the students of the participants to use Earth science data in a meaningful way and teach them skills with IT tools that they will carry with them in the future. The project produces customized educational activities that use Earth science data and data analysis tools featured in the Earth Exploration Toolbook, that will be made available to the broader educational community through the project Web site, the Using Data in the Classroom Portal of the National Science Digital Library (NSDL -- www.nsdl.org) and the Digital Library for Earth System Education (DLESE -- www.dlese.org). By having these tools on the web these resources are discoverable and thus usable to teachers nationally and internationally. The program involves 75 middle-school teachers over three years, 150 middle-school students in the summer workshops, and up to 9,000 students during the school year as the teachers implement the activities they developed during the summer with their students. Teachers are involved in a year-long teacher professional development program that includes a summer workshop and year-long support through online discussions, teleconferences and a one-day meeting. Customized data-rich activities cataloged in DLESE and elsewhere will be an outcome of this project, as will a group of teachers and students better prepared to use Earth science data and data analysis tools to help them understand current societal issues.
