PROBLEM-BASED GEOPHYSICAL LEARNING EXPERIENCES FOR UNDERGRADUATES

Over the past two years with the support of the National Science Foundation, hands-on, problem based, geophysical learning has been integrated into introductory undergraduate geology laboratory and undergraduate research experiences at Wofford College. The ability to quickly and non-invasively study multiple aspects, such as the role of fundamental forces and processes as well as environmental and cultural factors, associated with geological and archaeological situations, makes geophysical learning experiences particularly attractive and valuable for undergraduates. The ability to bring multiple geophysical (magnetic, resistivity, and electromagnetic -- ground penetrating radar) survey techniques to bear on the same or similar geological or archaeological field situations, thus facilitating comparative and holistic investigation and collaboration, is also highly desirable. Of particular importance is the ability of geophysical techniques to "see" below the surface in 2D, 3D, and in some cases 4D views. The development of the technical and conceptual skills of "seeing," or more correctly "modeling" in multiple dimensions is fundamental to understanding geological and archaeological content and contexts and solving problems relating to them. Another important benefit of learning how to use geophysical techniques is that students gain a critical understanding of the care and precision required to successfully obtain useable quantitative data and achieve interpretable results. Specific problem-based geophysical learning experiences are discussed in terms of the practical aspects of implementation and integration with learning objectives and assessment.
