The other day I was explaining to my students about open and closed minds when it comes to learning. While they sort of got it I found this chart that was developed by Carole Dweck to explain how it works. I spent a great deal of time explaining it and discussing it when one of them pointed out that the blue lines were semi circles and the green lines were fully formed and growing circles. When asked to explain it they said that more your mind is growing the stronger it becomes making your world a better place. (I'm paraphrasing here)
