Establishing a Geophysical Test Site

地质学（42）地球物理试验场（GTS）基本上是一个受控实验，对“发现”的物体具有精确的已知参数，是通过实践经验改进学生在地球物理学方面的实际和概念学习的一种潜在有效方式。 堪萨斯州立大学（KSU）正在建立一个GTS，用于本科教学。 各种各样的物体被埋在不同的深度内的GTS，和学生使用的地球物理测量仪器（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）的阵列来测量由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该网站的全面调查结果进行比较。 GTS正在整合到KSU提供的几门本科课程中，包括野外地球物理学，地球物理学导论，勘探地球物理学，计算地球物理学和水文地质学。 KSU教育创新和评估办公室（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。 K-12教师和学生在GTS活动中的推广和参与正在提供超越大学观众的教育效益。

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.
