Don't walk away from this thread assuming the authors are trying to dumb down math education without reason.
Instead, I'd encourage you to think about a few questions:
- Does raising the average math competency of all students outweigh the possible benefits of catering to a select few?
- Is it the school's (and thus, the government's) obligation to develop a hypothetical gifted student?
- If you're a student not enrolled in an advanced course (when one exists) do you assume that you're "not a math person"?
