To that end, I've tried hard to come up with mechanical ways to get people to listen to feedback. I was constantly helping my students develop their own feedback loops. It was not easy. Getting people to welcome feedback was the hardest thing I ever had to do as an educator. It hasn't been easy in my personal life, either. It saddens me that so many parents and educators have given up on this. When they talk of building self-esteem, they often resort to empty flattery rather than character-building honesty. I've heard so many people talk of a downward spiral in our educational system, and I think one key factor is that there is too much stroking and too little real feedback. When I taught the "Building Virtual Worlds" class at Carnegie Mellon, we'd do peer feedback every two weeks. This was a completely collaborative class, with the students working in four-person teams on virtual-reality computer projects. They were dependent on each other, and their grades reflected it.
