I love talking to kids about their PBL projects and hearing that the project is "really hard" or it doesn't have really clear instructions. Kids are designing their own learning and that is "really hard" for many of them to grasp. They want us to tell them what to learn and how to do it. This is how we "do" school.
I'm really proud of my teachers, all of whom have gone out on a limb to give kids a truly unique learning experience. They are pioneers and are making awesome decisions for kids each day. They know when to look back at the kid and say, "Wow, how WOULD you do that?" Which goes against everything in a teacher's brain.
