Given the climate crisis, how do environmental groups use communication to advance their aims? In this community-engaged learning course, students work with environmental organizations on professional communication projects. Students learn about rhetoric and communication as they refine and reflect on their writing processes and practice writing in multiple genres. Students create a variety of multimodal communication projects such as social media and web content for community partners. Through readings, reflection, discussion, and projects involving feedback from peers, instructor, and community partners, students learn principles and strategies to inform and persuade a variety of audiences about environmental issues.
