In 2018 I semi-retired by retiring from Weston High School after my 21st year teaching mathematics there. This was also my 44th year as a teacher altogether. In 2023 I retired fully, adding in my 18 years at Harvard’s Crimson Summer Academy each summer. For 21 years I had taught at the Saturday Course in Milton, MA, and I used to serve on the board of the Dorchester Historical Society.

I read, cook, and spend a lot of time building my model railroad. For some reason I’m left with less free time than would be ideal, considering that I’m supposed to be retired, but somehow I also manage to devote time to my wife, Barbara, and to our varying number of cats (once up to six, but now sadly down to one).

  • What does this have to do with math?

    By on

    Three different experiences in Algebra II today have caused me to rethink the value of projects. Although I’ve always had a theoretical appreciation of project-based learning, I’ve also always had grave doubts about placing a whole lot of emphasis on… Read More ›

  • Rubrics

    By on

    I was giving my Algebra II class more details about the project they had just started working on. It’s an exploration of exponential and linear functions, with a story line for which I cannot take credit but which I’m happy… Read More ›

  • Hell for the Holidays

    By on

    I just finished reading Hell for the Holidays, a thriller by Chris Grabenstein, author of Tilt-A-Whirl and other mysteries. Two years ago I recommended Tilt-A-Whirl enthusiastically. Unfortunately I can’t make a similar recommendation for Hell for the Holidays. Although it’s… Read More ›

  • Why do homework?

    By on

    “Why should I do homework if it isn’t going to be graded?” It’s tough to give a convincing answer to that question. Typically we point out that homework helps you learn, but that answer goes only so far. We may… Read More ›

  • The Yiddish Policeman's Union

    By on

    Just finished listening to the audiobook of The Yiddish Policeman’s Union, by Michael Chabon. This hybrid novel fits squarely in the hardboiled-detective genre — except that it also fits into the alternative-history genre. The premise is that the state of… Read More ›

  • There's nothing like promoting stereotypes

    By on

    Overheard in Weston: “She’s even more Asian than we are.” “How could that be? She’s blonde. She doesn’t look the least bit Asian.” “She gets better grades.”

  • Achilles and Odysseus

    By on

    A really interesting report on NPR’s All Things Considered the other day dealt with two different but intertwingled issues. One was the psychological reality of fictional characters. Some readers challenge the appropriateness of discussing the sexual orientation of Dumbledore, on… Read More ›

  • Cheating and imaginary property, Part Two

    By on

    This is a follow-up to my post of December 26. There are two separate and distinct issues here: Has there been a decline in ethical attitudes and behavior among students in recent years? Are some lines that used to be… Read More ›

  • New Year's Eve at Brasserie Jo

    By on

    Some time ago, Barbara and I decided that we would celebrate New Year’s Eve this year by going out to eat at Brasserie Jo. Verdict: definitely OK, but not worth the price. First of all, as the name tells you,… Read More ›

  • Ratatouille

    By on

    I wasn’t completely convinced that I wanted to watch Ratatouille, but it seemed like a good choice for light entertainment over winter vacation. And indeed it was. Don’t let the fact that it’s a Disney animation make you think that… Read More ›

  • Dangerous Admissions

    By on

    Almost any reader would enjoy Jane O’Connor’s satire, Dangerous Admissions, but it resonates especially well for anyone connected with an elite high school, public or private. The setting is the fictional but completely plausible Chapel School, an upper-class K–12 independent… Read More ›

  • Adventures at Microcenter

    By on

    So I’m at Microcenter on Wednesday to take advantage of their post-Christmas sale, and I walk in clutching their flyer with the descriptions of two external hard drives highlighted. These are advertised as being for both PCs and Macs, so… Read More ›

  • Quadratic equations will help Dorchester!

    By on

    Sounds unlikely, doesn’t it? How could quadratic equations possibly help Dorchester? Well, I should first note that we’re talking about quadratic relations —in particular, those represented by hyperbolas — not about quadratic functions in the familiar form of f(x)=ax2 + bx + c, represented… Read More ›

  • Cheating and imaginary property, Part One

    By on

    David Pogue has written a fascinating article about cheating and intellectual property — or imaginary property, as some call it. Pogue is a technology writer, but his article is aptly entitled “The Generational Divide in Copyright Morality.” Nevertheless, technology has… Read More ›

  • Match Point

    By on

    How can a Woody Allen movie be so boring? I just couldn’t make myself care about any of the characters in Match Point. There was no wit, no humor — in a Woody Allen movie of all things! Maybe I… Read More ›

  • Trees and rocks

    By on

    How tall is a tree? What color is a rock? These may sound like silly questions, but they have thrown themselves in my face as I build my model railroad. In the process, I’ve discovered a couple of facts that… Read More ›

  • Dorchester Open Studios

    By on

    Delayed post (originally written 10/28): I highly recommend visiting Dorchester Open Studios when it comes around again next year. This year’s event was well worth seeing, though Barbara and I only got to visit a fraction of the over-100 studios… Read More ›

  • Harry Potter movie #5

    By on

    Delayed post (originally written 8/24): Sigh. The movie of Harry Potter and the Order of the Phoenix turned out to be a disappointing mess. I had carefully avoided all reviews beforehand, but maybe they would have warned me. Usually I… Read More ›

  • Is 85% a B? Grading by percentages is not the way to go

    By on

    In a strictly non-scientific survey, 89% of all students and teachers indicated that they believe in traditional percentage-based grading, where an 85% would be a middling B, a 75% a middling C, and so forth. Actually, I just made up… Read More ›
