We don't need no education

Joanne Jacobs posts an excerpt from a one-minute speech by Dennis DeTurck, professor of mathematics at the University of Pennsylvania:

I have a simple suggestion when it comes to teaching students in elementary school fractions -- don't. Fractions have had their day . . . but in this digital age, they are as obsolete as Roman numerals.

Simply put, this is nonsense. Without understanding fractions, you cannot graduate from basic arithmetic to algebra or calculus.

Furthermore, anyone who thinks this way has never cooked for himself or learned music.
