Complex systems are at the root of our world’s most pressing problems and largest opportunities. This junior/senior capstone seminar introduces systems science. We will focus on concepts and practices used to define and analyze systems, helping students build competencies with systems thinking to describe, assess, understand and manage complex systems from local to global scales. The course will consider a range of topics including systems science, complexity and behavior of complex adaptive systems, networks, and patterns of organization. Seminar participants will gain direct experience applying a systems lens as both students and teachers by preparing and presenting a course project on one topic of their choice and working together to develop a syllabus for a possible new introductory course on systems thinking.
