What does one do when the book is wrong? Should the book’s authority outweigh the professor’s? In the mind of the student, the book is usually the “law” of the class, in many ways, and the teacher the lawyer. Obviously, I can’t hold the student accountable for missing a question when the book mislead her — and I did later give her full credit for her answer — but now I see another way in which grading is revision… not of the test, but of the textbook! —Mike Arnzen —When the Book is Wrong (PEDABLOGUE)
