Development and implementation of virtual field teaching resources: two karst geomorphology modules and three virtual capstone pathways

Abstract

During the summer of 2020, many geology field camps were canceled due to the COVID-19 pandemic, including the karst geomorphology field course I was scheduled to co-teach through Western Kentucky University. When the National Association of Geoscience Teachers (NAGT), in collaboration with the International Association for Geoscience Diversity (IAGD), began the project of supporting working groups to create online field experience teaching materials, this presented an opportunity. This paper describes the development of two activities derived from that field camp curriculum that are now freely available as peer-reviewed exemplary teaching activities on the Science Education Resource Center (SERC) Online Field Experiences repository under “Karst hydrogeology: a virtual field introduction using © Google Earth and Geographic Information Systems (GIS)” and “Karst hydrogeology: a virtual field experience using © Google Earth, GIS, and TAK [Topographic Analysis Kit].” Each product includes a student handout, an instructor workflow reference, a grading rubric, and NAGT-established learning objectives. The introductory activity is the more basic of the two, is expected to take about an 8 h workday to teach, and walks students through all the steps, as well as providing global examples of karst landscapes that can be virtually explored. The other activity, “Karst hydrogeology and geomorphology”, assumes student familiarity with © Google Earth, GIS, and karst drainage systems and is expected to take about twice as long as the introductory activity to teach. To make these learning opportunities financially accessible, all software required for the activities is open source, and alternative workflows for the introductory module are provided so that the entire exercise can be completed using a mobile device. Addressing this need for virtual capstone options during the pandemic, and providing a virtual alternative for years to come, these karst activities, along with a subset of other SERC activities, were assembled into three learning tracks, each one providing learning hours equivalent to a traditional field camp, that have been added to the course offerings at the University of Cincinnati Department of Geology. In addition to providing online capstone activities in the time of a pandemic, these learning materials provide alternative experiences to traditional field camps that are inclusive for all geoscience students.
