A story on NPR that I heard because I listen to NPR's most emailed stories. I think that this does not justify algebra to an M.A. in Mathematics for Teachers program, but it does talk about how calculators and computers have turned our need for an ability to do arithmetic to an ability to be "managers of numbers."

NPR's Scott Simon turns to Weekend Edition Math Guy Keith Devlin of Stanford University for help.
Here is the NY Times article about how the mobile phone industry is suggesting that cell phones are a good classroom tool to do algebra.
