They were elated. His teacher walked him out today to tell me that he had a phenomenal week at school this week. It was awesome to hear. I pointed out to him that it is possible...

I think that such a believe is either naive or arrogant. Or does one...

Thursday, November 13, 2014. Education: The Discovery of Our Soul. Long-time readers of this blog know that I believe strongly in education that goes beyond skills.
