Bringing Seismology's Grand Challenges to the Undergraduate Classroom

The "Seismological Grand Challenges in Understanding Earth's Dynamic Systems," a community-written long-range science plan for the next decade, poses 10 questions to guide fundamental seismological research. Written in an approachable fashion suitable for policymakers, the broad questions and supporting discussion contained in this document offer an ideal framework for the development of undergraduate curricular materials. Leveraging this document, we have created a collection of inquiry-based classroom modules that utilize authentic data to modernize seismological instruction in 100 and 200 level undergraduate courses. The modules not only introduce undergraduates to the broad questions that the seismological community seeks to answer in the future but also showcase the numerous areas where modern seismological research is actively contributing to our understanding of fundamental Earth processes. To date 6 in-depth explorations that correspond to the Grand Challenges document have been developed. The specific topics for each exploration were selected to showcase modern seismological research while also covering topics commonly included in the curriculum of these introductory classes. The activities that have been created and their corresponding Grand Challenge are: -A guided inquiry that introduces students to episodic tremor and slip and compares the GPS and seismic signatures of ETS with those produced from standard tectonic earthquakes (Grand Challenge "How do faults slip?"). - A laboratory exercise where students engage in b-value mapping of volcanic earthquakes to assess potential eruption hazards (How do magmas ascend and erupt?). - A module that introduces students to glacial earthquakes in Greenland and compares their frequency and spatial distribution to tectonic earthquakes (How do processes in the ocean and atmosphere interact with the solid Earth?). -A suite of activities that introduce students to oil and gas exploration, including an activity that introduces the concept of shale gas exploration (Where are water and hydrocarbons hidden beneath the surface?) -A guided inquiry module that leads students to understand the differences between lithosphere and asthenosphere (What is the lithosphere-asthenosphere boundary?) - A module where students explore earthquake hazards and probability of ground shaking in southern California, New Madrid, and their own location. (How does the near-surface environment affect natural hazards and resources?). To enhance the usefulness of these resources, all have been developed in a modular fashion that allows instructors to pick and choose some (or all) of these resources for integration in to the scope and sequence of their course. Each module will include an instructor's guide containing instructions for implementing the activity, assessment strategies, and other resources. Formative pilot testing at 2- and 4- year colleges will take place fall 2012. Ultimately, the modules will be disseminated online through IRIS's InClass web portal and through small training workshops. Current drafts of some of the activities can be obtained by emailing M.
