Student Analysis of Data Driving Learning about the Earth (SADDLE): A Next Generation GLOBE Proposal

学生分析数据驱动学习地球(SASTLE)：下一代全球建议学生分析数据驱动学习地球(SASTLE)项目为全球学生和教师提供机会，开展与流域科学相关的探究式调查。该项目正在创建学生友好的界面，使学生能够与与大学水文科学促进联合会(CUAHSI)正在建设的大型科学观测站有关的实时和存档数据库进行互动。正在探讨的具体主题包括：流经分水岭的水，人类活动如何影响分水岭，反之亦然，以及土地利用对分水岭生态系统的影响。两项新的开放式科学调查将使学生能够使用CUAHSI和来自他们自己流域的全球数据进行调查。在中学年级，学生们将调查分水岭的水量平衡，并制定数据收集策略，以探索系统中任何流量失衡的根源。一项更高级的研究允许高中生考虑土地利用变化对河流流量的影响，以及城市和农业发展对水质的影响。与许多其他全球项目不同，该奖项的重点是数据分析和解释，而不是数据收集。正在定制新的界面和可视化工具，包括地理信息系统技术，为非科学家提供对CUAHSI和GLOBE数据库的方便、无缝访问，使学生能够在“学习为用”的教育背景下进行定性和定量分析。正在制定基于浏览器和桌面环境的策略(基于我的世界)，以适应各个学校现有的不同技术能力。还在创建新的学习活动，帮助学生掌握进行不限成员名额调查所需的科学内容。在这些资源的设计过程中，几个机构的水文科学家正在提供内容方面的专门知识，在广泛传播之前，这些资源正在由一群教师进行实地测试。三种类型的专业发展讲习班(针对教师的基本和高级讲习班；针对CUAHSI人员的外联讲习班)将在授奖传播阶段提供关于如何使用这些学习活动和分水岭调查的培训。

Student Analysis of Data Driving Learning about the Earth (SADDLE): A Next Generation GLOBE ProposalThe Student Analysis of Data Driving Learning about the Earth (SADDLE) project is providing GLOBE students and teachers with opportunities to conduct inquiry-based investigations related to watershed science. The project is creating student-friendly interfaces that allow students to interact with the real-time and archived databases associated with the large-scale scientific observatory being constructed by the Consortium of Universities for Advancement of Hydrologic Science (CUAHSI). Specific topics being explored include the flow of water though a watershed, how human activities impact watersheds and vice versa, and land use impacts on watershed ecosystems. Two new, open-ended science investigations will enable students to conduct investigations using CUAHSI and GLOBE data from their own watersheds. In middle school grade levels, students will investigate the water budget for the watershed and developing data collection strategies to explore the origins of any flux imbalances in the system. A more advanced study allows high school students to consider the impacts of land use changes on stream flow and the effects of urban and agricultural development on water quality. Unlike many other GLOBE projects, the emphasis of this award is on data analysis and interpretation, rather than data collection. New interfaces and visualization tools, including GIS techniques, are being customized to provide non-scientists with easy, seamless access to the CUAHSI and GLOBE databases, allowing students to conduct qualitative and quantitative analysis within the "Learning-for-Use educational context. Both browser-based and desktop environment strategies (based on My World) are being developed, to accommodate the variable technological capabilities that exist at individual schools. New learning activities that help students master the scientific content needed to conduct the open-ended investigations are also being created. Hydrologic scientists at several institutions are providing content expertise during the design of these resources, which are being field-tested by a cohort of teachers before widespread dissemination. Three types of professional development workshops (basic and advanced for teachers; outreach for CUAHSI personnel) will provide training on the use of these learning activities and watershed investigations during the dissemination phase of the award.
