Integrating Applied Geophysics into a Student-Centered Undergraduate Curriculum

我们正在开发一门新的应用地球物理学课程，该课程是对麻省大学开发的教学模式的改编。我们也为地球物理学的本科生研究创造了新的机会。我们的应用地球物理学课程的实验部分包括六个模块，专门用于地震折射和反射，探地雷达，重力测量，直流电法，磁测量和井间地球物理学。每个模块有两个四小时的实地实验。讲师使用每种方法设计第一次调查，目的是展示正确的调查设计、数据收集、安全措施和数据减少。交替的学生小组在每个模块中领导第二个实验室，从而呼吁学生小组在设计调查，通过正向建模评估各种方法的局限性以及组织数据收集工作中发挥领导作用。这些由讲师指导的实验利用了校园外不同的地点。学生主导的调查正在校园的不同地点进行，包括我们的地球物理试验场和邻近的实验井场。解释包括来自多种地球物理方法的互补数据集。获得最先进的地球物理设备的新途径不仅对地质学专业的准备产生了重大的积极影响，而且对其他物理科学和工程专业的学生也产生了重大的积极影响。

Geology (42)We are developing a new Applied Geophysics course that represents an adaptation of a pedagogical model developed at the University of Massachusetts. We are also creating new opportunities for undergraduate research in geophysics. The lab component of our Applied Geophysics course includes six modules dedicated to seismic refraction and reflection, ground-penetrating radar, gravimetry, direct-current electrical methods, magnetic surveying, and cross-hole geophysics. Two four-hour field labs are devoted to each module. The instructor designs the first survey using each method, for the purposes of demonstrating proper survey design, data collection, safety measures, and data reduction. Alternating groups of students lead the second lab in each module, thus calling on student groups to take leadership roles in designing surveys, assessing the limitations of various methods through forward modeling, and organizing data collection efforts. The instructor-led experiments take advantage of diverse sites off campus. Student-led surveys are being conducted at various locations on campus, including our Geophysical Test Site and adjacent Experimental Well Field. Interpretations incorporate complementary data sets from multiple geophysical methods. New access to state-of-the-art geophysical equipment is having a major positive impact not only on the preparation of geology majors, but also on other physical science and engineering students.
