Thoughtful quote from John Dewey (1895). He writes about teachers as intelligent, critical thinkers and actors (came across it in Dana Goldstein’s recent book, The Teacher Wars):
It is . . . advisable that the teacher should understand, and even be able to criticize, the general principles upon which the whole educational system is formed, and administered. He is not like a private soldier in an army, merely expected to obey, or like a cog in a wheel, expected merely to respond to and transmit external energy; he must be an intelligent medium of action.
