Collaborative Research: Google Earth for Onsite and Distance Education (GEODE)

这一合作项目是在先前工作的基础上，根据谷歌地球虚拟地球仪的功能，扩大、增加和传播地球科学学习资源。该项目的组成部分包括：1）开发一套全球分布的交互式虚拟实地考察，为谷歌地球基地添加高分辨率的千兆像素全景图像、虚拟露头和标本，以及自动分级，2）使用地球引擎API将大型地球科学数据集集成到虚拟地球仪中，从而实现其他形式的基于探究的学习和本科生研究，3）扩展工具包，包括移动的应用程序，以使更广泛的教师和学生贡献众包的数据和教育资源的在线存储库，4）进行面对面和在线教师专业发展研讨会，以促进使用，和5）评估传播工作和学生的学习收益，通过调查相结合，点击流数据和前/后测试。该项目的智力价值在于它能够利用用户友好的尖端虚拟地球和千兆像素成像技术，使学生参与一系列学习活动和虚拟环境。评估是通过调查和前测试和后测试与更连续的点击流数据相结合的离散数据收集，以深入了解学生如何在这种虚拟环境中学习。该项目的更广泛影响包括：1）其适用性广泛的机构，无论是作为正式的课程作业，还是作为本科地球科学课程内外的辅助用途，2）使用面对面，网络研讨会和小组视频会议方法进行广泛的教师专业发展，3）专门针对职前科学教师的材料开发，以及4）为行动不便的学生提供访问，以及那些有工作或家庭承诺限制参与实际实地考察的学生。

This collaborative project builds on prior work to expand, augment and disseminate geoscience learning resources based on the affordances of the Google Earth virtual globe. Components of the project include 1) development of a suite of globally distributed interactive virtual fields trips which add high-resolution gigapixel panoramic images, virtual outcrops and specimens, and automated grading to the Google Earth base, 2) using the Earth Engine API to integrate large geoscience datasets into the virtual globe, enabling additional forms of inquiry-based learning and undergraduate research, 3) expanding toolkits, including mobile apps, to enable a broader range of faculty and students to contribute crowd-sourced data and educational resources to an online repository, 4) conducting face-to-face and online faculty professional-development workshops to promote use, and 5) assessing dissemination efforts and student learning gains through a combination of surveys, clickstream data and pre-/post-tests.The intellectual merit of this project lies in its ability to leverage user-friendly, cutting-edge virtual-globe and gigapixel-imaging technology to engage students in an array of learning activities and virtual settings. Assessment is combining discrete collection of data through surveys and pre- and post-tests with more-continuous clickstream data to provide insights into how students learn in such virtual environments.The broader impacts of the project include 1) its applicability across a wide range of institutions, both as formal course assignments and for ancillary use in and beyond the undergraduate geoscience curriculum, 2) extensive faculty professional development using face-to-face, webinar and group-video-conferencing approaches, 3) materials development specifically for pre-service science teachers, and 4) provision of access for mobility-impaired students, as well as those with work or family commitments which limit participation in actual field trips.
