The polarizing nature of many science-based topics often causes people to engage in a hostile manner with those who have differing perspectives. As the next generation of scientists and industry professionals, students studying in science-based disciplines must understand the value of civil discourse. Additionally, they need the skills necessary to engage civilly with individuals whose beliefs differ from theirs as one way to improve relations between the science community and lay audiences. Civil discourse challenges students to apply best practices of science communication in impromptu discussion, think critically about alternate perspectives, and empathize with the experience of others. The classroom activity builds upon improvisation techniques which enable students to define civil discourse, articulate the importance of civil discourse in science communication, and use civil discourse techniques when engaging in difficult conversations about science. Courses: Science communication courses across course levels to improve students' ability to engage in civil discourse when discussing controversial science topics. Objectives: This activity aims to teach students to: (1) define civil discourse; (2) articulate the importance of civil discourse in science communication; and (3) use civil discourse techniques when engaging in difficult conversations about science.
