• High-school math in the 21st century?

  By ljd42 on May 25, 2005

  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

  By ljd42 on May 24, 2005

  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?

  By ljd42 on May 24, 2005

  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 ›

• A presentation in 10 minutes or less?

  By ljd42 on May 22, 2005

  Dennis and Jim and I have been invited to present a paper at the TeachScheme Tenth Anniversary Workshop in Providence on June 11. At first we were allocated ten minutes! Not ten minutes apiece, but ten minutes total. But wait,… Read More ›

  If you are dealt a hand of five cards, what is the probability that you have three diamonds and two clubs? There are (at least) two different approaches to this kind of problem: The chance the first card is a… Read More ›

• Learning in fourth grade — on Saturdays

  By ljd42 on May 21, 2005

  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

  By ljd42 on May 20, 2005

  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!

  By ljd42 on May 19, 2005

  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 ›
