This Organized Oral Session focuses on the use of citizen science in undergraduate courses. Citizen science is the involvement of the public in the scientific process to facilitate large scale data collection and analysis. It is increasingly being used in a variety of settings, including informal learning centers, K-12 schools, and higher education. The use of citizen science in higher education is thought to be a way to increase student engagement, highlight the real world relevance of course activities, and introduce students to the principles of research. A recent report by the National Academies of Sciences, Engineering, and Medicine concluded that involvement in citizen science benefits participants, scientists, communities, and science more broadly. However, many individuals do not have experience with citizen science in higher education. This session showcases some ways in which citizen science has been used in undergraduate courses with the goal of increasing dialogue between different citizen science stakeholders (project developers, project evaluators, scientists relying on the data generated through citizen science, course instructors). These presentations suggest ways in which instructors could use ecologically-themed citizen science in their courses. In addition, they highlight ways in which citizen science project developers and scientists using data generated from these projects can make their projects more accessible to undergraduate classroom settings.
