## High-school math in the 21st century?

What math applications are taught in high school? Principally parabolic arches and widget-manufacturing, of course. This is a bit of an exaggeration, but the principle holds. We teach applications like those rather than cryptography and models of voting. At the… Read More ›

## Martin Gardner for pennies

The Mathematical Association of America is selling a CD containing 15 Martin Gardner books (the entire collection of his Scientific American columns) for a mere \$55.95 — or \$44.95 if you’re a member!

## Where are the girls?

Why do so few girls sign up for computer programming courses in high school? High school may be too late. The problem might be starting much earlier. Even in fourth grade at The Saturday Course (see my post on 5/21),… Read More ›

## Learning in fourth grade — on Saturdays

For about half of the Saturdays each year, I teach in a wonderful program called The Saturday Course. This is an enrichment program for gifted and talented public-school and parochial-school students in grades four through six. Small classes, dedicated faculty,… Read More ›

## Risks and probabilities

We know that both adults and kids are notoriously bad at estimating probabilities. Bruce Schneier (one of the world’s leading experts on security, cryptography, etc.) has this to say concerning risks and probabilities: One of the things I routinely tell… Read More ›

## Kids can’t concentrate? Don’t believe it!

Most exciting event of the week: I’ve been sitting here proctoring MCAS for the past two and a half hours. Actually, it isn’t exciting (surprise, surprise). But I’ve gotten quite a lot of work done. I don’t think I’m allowed… Read More ›
