Teaching is about learning
I read a very cool quote the other day in Einstein’s Unfinished Symphony: Listening to the Sounds of Space-Time by Marcia Bartusiak about teaching. In the book, she is quoting John Archibald Wheeler who more or less single handedly brought Einstein’s Theory of General Relativity back into the mainstream back in the 1960s.
bq. Much of the best teaching comes out of research, and much of the best research comes out of teaching. If the class hour doesn’t end with the teacher having learned something, he doesn’t know how to teach.
