Integration of Near-surface Geophysical Imaging Technology into a Geoenvironmental Science Undergraduate Curriculum

地球系统科学(40)这个项目将浅层地球物理数据的收集、分析和解释整合到地球环境研究课程中。这种方法不同于其他机构实施的模式，它侧重于本科教育，并将地球物理技术纳入多门地理和地质学课程以及个别学生的研究经验。该项目建立在过去在地表分水岭过程中开发实地学习机会的方案的基础上，并正在通过构建“课程桥梁”将通过探地雷达、电阻率和电磁成像实现的调查整合到多门课程中。项目设计结合了对当地地质的研究，包括对岩溶地形(天坑发育、流失溪流、洞穴、泉水)、复杂水文地质环境(地表水-地下水在不同地质材料中的相互作用)、构造控制(断层、岩性变化等)的调查。水文学和管理问题(井口保护、场地开发、垃圾渗滤液监测)。该项目为数百名学生(历时数年)提供机会，使他们有机会获得将复杂环境问题概念化和解决的高级技术和数量技能，培养与问题概念化、分析和解决有关的关键技能，使学生接触到实地数据收集的时间和空间背景，并提供机会了解所使用的各种地球物理场方法的理论基础以及实践能力和局限性。该项目包括形成性和总结性评价，以衡量其采用的“课程桥梁”方法的成功程度。项目成果，包括课程/教学材料、学生研究项目成果和评估结果，正在通过科学教育资源中心(SERC)网站、美国地质学会(GSA)会议上关于本科生教育中地球物理学的特别会议、一系列地区社区讲习班以及本科生和教职员工在适当场所的演讲和出版物进行传播。

Earth Systems Science (40)This project integrates shallow geophysical data collection, analysis, and interpretation into the Geoenvironmental Studies curricula. The approach differs from models implemented at other institutions by focusing on undergraduate education and by incorporating geophysical technology in multiple geography and geology courses and in individual student research experiences. The project builds on past programs that developed field learning opportunities in surface watershed processes, and is integrating investigations made possible through Ground Penetrating Radar, Electrical Resistivity, and Electromagnetic Imaging in multiple courses via construction of a "curriculum bridge". The project design incorporates studies of local geology, including investigations of karst terrains (sinkhole development, losing streams, caves, springs), complex hydrogeologic settings (surface water-groundwater interaction in variable geologic materials), structural controls (faults, variations in lithology, etc.) of hydrology, and management issues (wellhead protection, site development, landfill leachate monitoring). This project provides opportunities for hundreds of students (over several years) to acquire advanced technical and quantitative skills for conceptualizing and addressing complex environmental problems, builds critical skills related to problem conceptualization, analysis, and solution, exposes students to the temporal and spatial context of field data collection, and provides opportunities to understand the theoretical basis as well as the practical capabilities and limitations of the various geophysical field methods used. The project incorporates formative and summative evaluations to measure the success of the "curriculum bridge" approach it utilizes. Project outcomes, including curricular/instructional materials, results of student research projects, and the evaluation results are being disseminated via the Science Education Resource Center (SERC) website, a special session on geophysics in undergraduate education at a Geological Society of America (GSA) meeting, a series of regional community workshops, and by presentations and publications by undergraduates and faculty members in appropriate venues.
