Collaborating with colleagues
We had an interesting K–12 professional development (PD) day yesterday (as our students were enjoying a four-day weekend and we teachers had to settle for three days off). The theme for the year is differentiated instruction (DI); the specific focus… Read More ›

Firing a teacher, part two
A first-year teacher was fired last week for making a bad judgment call. Depending on the version of the story you believe, he either duct-taped a student’s mouth shut or gave her some masking tape and asked her to tape… Read More ›

I'm delighted to learn that I was wrong
In my review of Transit Maps of the World a couple of days ago, I made the following observation: I have to admit that it will appeal strongly only to readers who are fascinated both by cartography and by railroads,… Read More ›

Adults and math: Who needs a formula?
OK, this is just one example. It’s purely anecdotal evidence, and therefore it doesn’t prove anything. But it’s still indicative of a problem with adult attitudes toward math. A bit of background first: if you don’t have the good fortune… Read More ›

Transit Maps of the World
This gorgeous book — I might even call it stunning — must have a rather limited audience. Although I’m tempted to add it to my list of favorite books (see my profile in this blog), I have to admit that… Read More ›

Mathematicians are Platonists
In this past Sunday’s New York Times Book Review, Jim Holt wrote a mildly interesting review of the new book by John Allen Paulos, Irreligion: A Mathematician Explains Why the Arguments for God Just Don’t Add Up. Since I haven’t… Read More ›

Life imitating art: Academy X & Firing a teacher, part one
Continuing my accidental theme of reviewing works of fiction about life at elite high schools, such as Prep, Restless Virgins, and Dangerous Admissions, I have just finished reading Academy X, a satirical novel by Andrew Trees. It’s not clear whether… Read More ›

A reader of both this blog and Adam Gaffin’s Universal Hub asked why I’ve turned off comments in my blog. Naturally he had to ask the question on Universal Hub. I replied as follows: I have comments turned off because… Read More ›

The fuzzy math of Huckabee's FairTax
There are many things to dislike about Mike Huckabee’s proposal for a 30% national sales tax, the so-called Fair Tax, such as the fact that it’s thoroughly regressive. (It would lower taxes slightly for the poor, lower them tremendously for… Read More ›

Stay off the main drag
“Please if possible stay off Dorchester ave until the community gets more information,” writes a well-known Dorchester community activist with an incendiary temperament. This sentence was part of a mass email sent out in response to a targeted killing on… Read More ›

Can a middle-aged professional become a math teacher?
We had an interesting visit yesterday from a local accountant who is considering making a mid-career switch and becoming a math teacher. He spent most of the day at Weston High School, talking with teachers and kids and observing classes…. Read More ›

What does this have to do with math?
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
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
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?
“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
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
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
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
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 ›
