So just received some publicity in the Wisconsin State Journal for our work in the Samsung Solve for Tomorrow contest - we are using our green project to reduce Juda school's carbon footprint as the basis for the contest.
This is the work that makes students see and do what the real world wants from students. Big goals, no set plan, students trying and revising -- it is problem solving. All you have to do is pick a problem and set them free. If it is a genuine thing and they own it. Too often we try and control how a project ends, for a project to have a real impact there has to be challenges and chances to fail.
And as the teacher your job is to motivate and keep up the student's level of tenacity. When that happens good things happen.
