To indoctrinate your students?
Well, now really, let's think about this. I agree that this is ridiculously politically slanted in one direction. But if we're going to use "story problems," why shouldn't we demonstrate how useful math is in analyzing social and political matters?
And shouldn't teaching math have the end of preparing students to function competently as citizens, voters, and consumers of news media? I'm thinking of the issues raised in the very cool book "A Mathematician Reads the Newspaper."
UPDATE: More on teaching math here.
IN THE COMMENTS: Lots of actual right-wing math story problems!
