Why Johnny can't code

"Imagine being the parent of a 15-year-old sophomore at an elite high school who comes home with a report card ranking him near the bottom of his class in math. Knowing your child will soon enter the same job market as his classmates, would you be concerned? Would you work with him to improve? Would you begin to question the way math is taught in school? The United States got such a report card in December, when an international test ranked our 15-year-olds 24th in math out of 29 industrialized nations that belong to the Organization for Economic Cooperation and Development."
