This document discusses how teaching students to "think like time travelers" can help develop their skills as systems thinkers. It suggests having students determine destinations, gather resources, identify leverage points, experiment with solutions, execute plans, and assess situations. Examples are provided of scenarios teachers could use that would require students to think like time travelers, such as considering how numerical systems may have developed differently or how housing developments impact prairie dog populations. The overall message is that by designing learning experiences where students problem-solve open-ended scenarios, they can learn important skills for an unknown future.
