10-second review: Why not instead be a doctor or lawyer or scientist?
Title: “Priest, Prostitute, Plumber? The Construction of Teachers as Saints.” C Carter. English Education (October 2009), p. 61.
Answer to the question from an ad, paraphrased by Kristy, a secondary English education candidate: “…without teachers there would not be any doctors, lawyers, scientists or members of any other professions.”
Comment: I like that answer better than “to change the world” which the National Council of Teachers of English (NCTE) and International Reading Association (IRA) seem to promote in the pages of their professional journals.
