If you are like some organizations - churches, schools, mission agencies - you probably decompress your teams around the idea of what you already do or what you already know. Your goal is to get people more engaged with what you are already involved in, what exists now, what things you are currently resourcing. I'm not saying that is a bad thing.
What might serve us all better is what Alan Hirsch calls missional imagination - what can your students dream up that no one knows about... yet. Instead of helping your students get plugged in to what you know, maybe you should help them engage something they know that you don't.
I am not saying this is simple or easy. This requires you to unleash people. To empower them and send them out. Untether them and allow them to dream. Risky, brave, filled with potential for failure. That's the apostolic.
