How do people and organizations move forward on sustainability challenges when values, incentives, and perspectives do not align? This Honors seminar builds on the Constructive Communication Across Difference (CCAD) framework to develop socially competent communicators who can engage meaningfully across differences in real-world sustainability challenges, such as regional economic resilience, community development, and resource use, where governments, businesses, and communities must work together under constraint. Students explore how worldviews, shaped by values, beliefs, and assumptions, influence how individuals and groups understand these challenges and interact within communities. Through learning labs, case studies, and applied exercises grounded in real-world contexts, students practice communication strategies such as curiosity, active listening, structured dialogue, and reflection to engage constructively across differences. The course emphasizes how communication shapes decision-making in complex systems where no single “correct” path exists. Students will connect classroom learning to real-world practice through community engagement and applied experiences. By the end of the seminar, students will be prepared, as emerging leaders, to communicate across difference with clarity, think critically within complex systems, and contribute constructively within their communities.
