The transition towards societal level sustainability requires thinking and acting anew. Traditional design pedagogy poorly equips designers to integrate long-range strategic thinking with current human-centered design methods. In this paper, we describe a three-course sequence: Dexign Futures Seminar (DFS), Introduction to Dexign the Future (iDTF), and Dexign the Future (DTF). The term dexign indicates an experimental type of design that integrates Futures Thinking with Design Thinking. Students learn to engage strategic long time horizon scenarios from a generative design perspective. DFS, online modules, teaches students to critique and deconstruct existing futures scenarios. iDTF situates students to explore futures based themes and apply design methods and research techniques. DTF takes students into a semester-long project designing for 2050. In this paper, we describe lessons learned that lead to a pedagogy for supporting novices as they develop skills and methods for long time horizon futures design.
