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).

Missing the point?
As you know, the devil is in the details. Details, you say? Well, the Math Curmudgeon is always worth reading…but I often disagree with him, most especially with some of his details. Consider his post “Missing the Point,” which deals primarily… Read More ›

Temari balls
We traditionally cap off Honors Geometry by ending the course with a brief exploration of non-Euclidean geometries. In recent years we have focused on geometry on the surface of a sphere; we ask freshmen to pretend that they are living on… Read More ›

Sea Breeze revisited
Just over four years ago, I favorably reviewed the Sea Breeze Mexican Grill, which had just opened in our neighborhood. This restaurant chugged along for a while, being an adequate neighborhood restaurant but nothing special. My initial enthusiasm began to wane…. Read More ›

How science and math see each other
Ben does it again! We’re back to Math with Bad Drawings, with another post that resonates deeply with me as a math teacher. It begins with the somewhat startling claim that “mathematicians and scientists don’t share all that much in common.” How… Read More ›

The Cats: a photo-essay
Back in March…and April…and May…a group of freshmen kept pestering me (nicely, of course) to write a photo-essay about my cats, so I finally gave into the pressure and wrote one. Just follow this link.

Oliver Sacks
I’ve long been an admirer of Oliver Sacks — see, for instance, my post on Musicophilia — but it was his recent announcement that he is fatally ill that led me to want to read more than just that book… Read More ›

Reactions to the NCTM Annual Meeting
Fortunately I didn’t write this report just now! (I wrote it at the end of April, right after the NCTM meeting. I never would have remembered all these details if I had waited three and a half months.) Just follow… Read More ›

A return to blogging
So…how long has it been since I blogged? Almost a year? Well, ten months anyway, which is far too long a hiatus. So I’m resuming as of today. I am hoping for at least four posts a week, and probably… Read More ›

Delvyn Case explains the Beatles.
Music professor and composer Delvyn Case gave a refreshing and informative talk yesterday afternoon about the music of the Beatles. The talk, of course, was part of the Dorchester Historical Society’s lecture series. Of course. What do I hear you… Read More ›

Another Sunday with the Common Core
Three more perspectives on the Common Core State Standards: For all my doubts and negative reactions to the Common Core, I start feeling sympathetic to it when I read articles with headlines like “Common Core is Indoctrinating Kids with Socialism”: if right-wing… Read More ›

What we value in students
Always interesting Tina Barseghian, a blogger for KQED, wrote a recent post about what we should value in our students (beyond test scores, as she explicitly points out). She included a great infographic (by Jackie Gerstein), quoted below. Reading it… Read More ›

When Desmos fails
I have become a great fan of Desmos, a free web-based graphing calculator app. It is easy to use and remarkably powerful, providing evaluations, graphs, tables, and probably a lot of other things that I haven’t learned yet. What’s especially… Read More ›

Turmoil and Transition in Boston: A Political Memoir from the Busing Era
This is an engaging memoir by Boston politico Larry DiCara, former City Councillor and former mayoral candidate. Part political history, part personal, it provides a convincing insider’s account of Boston politics in the ’70s and ’80s, focusing on the busing… Read More ›

More on the Common Core
Right when I’m writing several posts about the Common Core, it’s not entirely coincidental that the Boston Globe had a big article about it this morning. Focusing on teacher training (a.k.a. professional development, or PD), the first few paragraphs of Alexandria… Read More ›

What works in education (revisited)
How do we know what works in education? Educational experiments are always suspect, since it’s impossible to control all the variables. There are also ethical issues involved in experimenting on students. So how can we possibly measure the effectiveness of… Read More ›

Only in Georgia? The Atlanta teacher scandal
Why isn’t there more outrage about this? Yes, teachers are human, so we make mistakes. Mistakes in math are excusable, as long as they aren’t too frequent or too egregious. But mistakes in ethics and law are inexcusable. Teachers who… Read More ›

The Triple Package
It doesn’t feel that long, but it turns out that it was three and half years ago that I reviewed Amy Chua’s previous book, Battle Hymn of the Tiger Mother. Her new book, written in collaboration with her husband, Jed Rubenfeld, is… Read More ›
