I managed to get the images to work this time, so here are some of the things year 9 students drew when I asked them 'What makes good feedback?'
However, the images below I found really profound and deep. The group that produced these images were the proudest of their achievement, and you can see why. The concepts they suggested were really good. I even took their work to the head of the department. She was quite pleased with them as well, and suggested that I pass them along. I may do that! We shall see!
Overall, I think these images would make pretty cool displays, or go nicely on a PPT presentation. The vending machine idea appeals to me especially, because it's not a connection I would have made on my own.
