The significant thing about Dr. Kline's paper is the question it raises in the mind of the reader. Is Dr. Kline finally coining around to the point of proposing a new mathematics curriculum for the high school and doing something about it? He will certainly not make the mistake, made by many of us in the past ten years, of calling it “modern mathematics.” The idea for the first-year algebra is here; and, though he says, “The content … is the traditional one,” this is not entirely true; certainly its organization is not traditional. If he would now find what mathematics is being taught in grades 1-8 and obtain the help of some good high school teachers who know how students of this age level learn, he could write a book, and then all of us could find out what he is talking about.
