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).

Credit Recovery
“Credit recovery” is another appalling consequence of No Child Left Behind. Although I know that it’s not politically correct to characterize it this way, that’s how I see it. Let’s see what it is and how its cheerleaders write about… Read More ›

Faithful Place and Broken Harbor
It sounds like an old chewing gum commercial: Do you want to double your reading pleasure? Then check out two more beautifully written psychological thrillers by Tana French. Technically, I suppose, they are murder mysteries in the police-procedural sub-genre, but… Read More ›

Annabelle's
The late lamented CF Donovan’s, in the Savin Hill neighborhood of Dorchester, closed its doors for good just over three years ago. Barbara and I had always enjoyed eating there — not for its gourmet food, but for the standard… Read More ›

A bad sign
I fear that 88 Wharf, which I reviewed three years ago, is going downhill. The rumor is that it’s about to go out of business. I don’t know whether that is really true, but the subject line of their recent… Read More ›

Soup and suans
Changsho may or not be the best Chinese restaurant in Cambridge, but it definitely has the best hot-and-sour soup. Mary Chung may or may not be the best Chinese restaurant in Cambridge, but it definitely has the best suan la… Read More ›

Camry electronics
After our eight-year-old Ford Taurus bit the dust, Barbara and I bought a 2012 Toyota Camry. I love the car, and I’m still learning its ins and outs. In particular, I have been pleasantly surprised by its electronic capabilities, especially in… Read More ›

Privilege
I suppose I’m biased. But bias or no, Privilege is must reading for anyone interested in the intersection of education, schools, and the American class structure. The full title of Shamus Rahman Khan’s sociological study is Privilege: The Making of an Adolescent… Read More ›

The Woman Who Died a Lot
Unless you’ve been reading this blog for at least the past six and a half years, you probably don’t realize that I’m a fan of Jasper Fforde. See my posts of 11/1/11, 11/30/06, and 8/8/06 for more information, but here… Read More ›

Popsicles, law, and language
Companies have to protect their trademarks, of course. There are even a few well-known examples where trademarks were lost because they weren’t protected — Wikipedia cites aspirin, dry ice, escalator, kerosene, laundromat, linoleum, phonograph, thermos, videotape, and zipper — so… Read More ›

XO
XO is the latest novel by Jeffery Deaver, two of whose books I previously reviewed — on August 27, 2006, and on November 23, 2009 — although I’ve read many more of his books than those two. In fact, I suspect that… Read More ›

Playtime
I’m not quite sure what I think of this 1967 Jacques Tati movie, which I just saw for the first time. It’s a bit slow, a bit French, and a lot jarring. The set is supposed to look like Paris,… Read More ›

Persistence
NPR aired a fascinating report this morning in its Your Health segment of Morning Edition: “A Struggle For Smarts? How Eastern And Western Cultures Tackle Learning,” reported by Alix Spiegel. Everyone knows the stereotype of the successful Asian student, and there’s… Read More ›

The Dead Puppy Theorem
(a + b)2 = a2 + b2. Right? “No, of course not,” you say. Or maybe you say “Yes, of course.” If you say yes, you’re making the same mistake that 42% of high-school students make. I just invented that statistic on the spot,… Read More ›

MIT does not equal Mitt
They don’t even sound alike. An MIT alumna was nearly prevented from voting in Florida because she was wearing an MIT shirt. A poll worker thought she was illegally campaigning for Romney inside the polling place.

What motivates teachers and students?
This is important! You’ve got to set aside ten minutes and watch this TED talk by Dan Pink. While it’s not specifically about teachers, nor specifically about students, it tells us a lot about what motivates and doesn’t motivate both groups. Presented by… Read More ›

Fractal pancakes!
Maybe some of my precalculus students will make fractal pancakes for the Fractal Fair in March (though I’m not sure where we could serve them, as the Fair is held in the school library). Here’s what they look like:

An excellent way to improve a school's test scores
What’s the best way for a school to improve its test scores? That’s easy: you get rid of all the low-performing students, of course. Or you send truant officers to their homes on the morning of test day, and the… Read More ›

How many other good teachers are going to quit for similar reasons?
A North Carolina teacher named Kris Nielsen recently posted a letter that has been finding its way around the Internet. As a teacher in Massachusetts, I am fortunate not to have the problems that she reports, but they ring all… Read More ›

Emulating the TI-84
American schools have been using Texas Instruments calculators for more than a quarter of a century now. They have become the de facto standard. More recently, computers and projectors have become ubiquitous, so you would think that we would have a better… Read More ›
