Establishing a Geophysical Test Site

地质（42）地球物理试验场（GTS）基本上是一个控制实验，对被“发现”的物体进行精确的已知参数，是通过实践经验提高学生在地球物理方面的实践和概念学习的潜在有效方法。堪萨斯州立大学（KSU）正在建立一个用于本科教学的GTS。各种物体被埋在GTS内不同的深度，学生们使用一系列地球物理测量仪器（磁力计、探地雷达、宽带电磁金属探测器、重力仪、激光全站仪和地震反射/折射）来测量物体产生的地球物理异常。然后，学生们处理和解释这些数据，他们关于物体的大小、形状、深度和物理特性的结果可以与我们对现场的全面调查结果进行比较。GTS被整合到KSU提供的几门本科课程中，包括现场地球物理学、地球物理学概论、勘探地球物理学、计算地球物理学和水文地质学。KSU教育创新与评估办公室（OEIE）正在评估GTS在改善学生学习这些课程方面的有效性。GTS将持续数十年，并将使教师能够有效地利用一系列地球物理仪器，为KSU和邻近机构的数百名本科生提供积极的实践学习经验。拓展和参与K-12教师和学生在GTS活动提供教育效益超出了大学观众。

Geology (42) A geophysical test site (GTS), basically a controlled experiment with precisely known parameters for the objects being "found", is a potentially effective way in improving practical and conceptual student learning in geophysics through hands-on experiences. A GTS is being established for use in undergraduate teaching on the campus of Kansas State University (KSU). A variety of objects are buried at varying depths within the GTS, and the students use an array of geophysical surveying instruments (magnetometer, ground penetrating radar, broadband electromagnetic metal detector, gravimeter, a laser total station, and seismic reflection/refraction) to measure the geophysical anomalies generated by the objects. Students then process and interpret this data, and their results regarding size, shape, depth, and physical properties of the objects can then be compared with results from our comprehensive surveys of the site. The GTS is being integrated into several undergraduate courses offered at KSU, including Field Geophysics, Introduction to Geophysics, Exploration Geophysics, Computational Geophysics, and Hydrogeology. The KSU Office of Education Innovation and Evaluation (OEIE) is assessing the effectiveness of the GTS at improving student learning in these courses. The GTS will last for decades, and will enable faculty to make effective use of an array of geophysical instruments in providing active, hands-on learning experiences for hundreds of undergraduate students at KSU and neighboring institutions. Outreach to and involvement of K-12 teachers and students in GTS activities is providing educational benefits beyond the college audience.
