Immersive In-Person Field Courses during the Pandemic: Minimizing Risk while Maximizing Efficacy.

Field courses can provide formative experiences that also reduce disparities in STEM education. Impacts of the ongoing COVID-19 pandemic on-field programs have been particularly severe, as many institutions shifted to online instruction. Some courses retained in-person field experiences during the pandemic, and achieved high student learning outcomes. Here, I describe an approach to mitigating risk of COVID-19 and other hazards during expedition-based field courses, and student learning outcomes achieved using that approach. I applied comprehensive risk management to in-person field expeditions that treated COVID-19 as a hazard, requiring mitigation to maintain an acceptable low level of risk. Prior to broad availability of COVID-19 vaccines, we applied a coronavirus-free "bubble" strategy in which all participants passed a COVID-19 PCR test immediately before departure and then avoided contact with people outside our bubble. In the future, vaccination can reduce risk further. We implemented additional safety factors to reduce risk of incidents that could require evacuation into medical facilities overloaded with COVID-19 patients. The courses were successful: we had no infections or other serious incidents and student learning outcomes were transformative. The approach provides a model for conducting immersive field courses during the pandemic and beyond. Several field course networks are implementing similar approaches to restore valuable field education opportunities that have declined during the pandemic.
