The Co Vis Testbed: A National Science Education Collaboratory

小行星9454729 本提案中的工作建立在通过协作可视化（CoVis）项目（NSF-AAT测试平台）进行学习的基础上。 CoVis专注于三个领域-项目增强的科学学习，协作和科学可视化-作为改变科学教育的手段。 其目标是在高度互动的网络协作环境中，利用下一代技术，通过丰富的媒体通信和科学可视化工具，支持学习社区的形成和工作活动。 NIE测试平台将把有300名高中生参与的小规模工作CoVis模型转变为一个大规模的合作实验室，供不同环境中的数千名用户使用。 在探索教育的网络基础设施时，必须认识到“基础设施”不仅仅包括网络连接和传输协议。 为了有效地支持网络学习社区，需要三个相互依存的组成部分：技术基础设施、教育内容基础设施以及教师支持和发展基础设施。 为了确定成本和成果的特点，试验台还需要一个评估和传播基础设施。 技术基础设施将为学生和教师提供一个支持协作学习的环境，包括视频电话会议、协作软件、视频服务器、互联网工具和开放式科学调查的软件环境。 教育资源基础设施将利用技术基础设施，使学生和教师能够查阅和交流各种交互式多媒体学习材料和科学数据集。 这些资源将由教师，学生，UIUC的大气科学家，Exploratorium科学博物馆的实践学习专家和其他合作者开发。 教师发展和支持基础设施的形式将包括：由项目工作人员为教师举办讲习班、提供支持项目导向教学法的材料，以及建立一个新兴的教师网络社区，分享他们在改革教学实践时的经验。 测试平台评估和传播基础设施将包括一个结合认知科学、调查方法和案例研究的实质性研究框架，以帮助揭示部署高带宽网络基础设施用于教育的挑战，并澄清这些基础设施如何提高科学教育的有效性。 这项研究的结果将通过各种传统和网络机制传播，以达到学校管理人员，决策者，公司和研究人员的受众。

9454729 Pea The work in this proposal builds on the Learning Through Collaborative Visualization (CoVis) Project, an NSF-AAT testbed. CoVis has focused on three areas - project-enhanced science learning, collaboration, and scientific visualization - as a means for transforming science education. Its goal has been to use next- generation technologies to support the formation and work activities of learning communities with media-rich communication and scientific visualization tools in a highly interactive networked collaborative context. The NIE testbed will transform the small-scale working CoVis model with three hundred participants at the high school level into a large-scale Collaboratory, for thousands of users in diverse settings. In exploring networking infrastructures for education, it is essential to recognize that "infrastructure" consists of more than network connections and transport protocols. To be effective, support for networked learning communities requires three interdependent components: technology infrastructure, educational content infrastructure, and teacher support and development infrastructure. In order to characterize costs and outcomes, a testbed also requires an evaluation and dissemination infrastructure. The technology infrastructure will provide students and teachers with an environment to support collaborative learning that includes video teleconferencing, collaboration software, a video server, Internet tools, and software environments for open-ended science investigations. The educational resources infrastructure will take advantage of the technology infrastructure to allow students and teachers to look up and exchange a broad range of interactive multimedia learning materials and scientific datasets. These resources will be developed by teachers, students, atmospheric scientists at UIUC, specialists in hands-on learning at the Exploratorium Science Museum, and other collaborators. The teacher development and supp ort infrastructure will take the form of workshops for teachers conducted by project staff, materials to support project-oriented pedagogy, and an emerging networked community of teachers sharing their experiences as they transform their teaching practices. The testbed evaluation and dissemination infrastructure will consist of a substantial research framework combining cognitive science, survey methods, and case studies to help expose the challenges for deploying high-bandwidth networking infrastructures for education and clarify the ways in which these infrastructures can improve the effectiveness of science education. The results of this research will be disseminated through a variety of traditional and network-based mechanisms to reach an audience of school administrators, policy makers, corporations, and researchers.
