The time is 8:30 this morning. The scene is the front of Greenleaf Hall at Milton Academy, as the day begins at The Saturday Course. A mom drops off her fourth-grader. We listen in on their remarks: Mom: Have a… Read More ›

Cellphones: A cautionary tale
During yesterday’s Massachusetts Math League meet in Westford, a cell phone belonging to a student from a nearby high school (neither Weston nor Westford) emitted a tone during the first round. She pulled the phone out of her pocket, looked… Read More ›
Interactive whiteboards
Yesterday was an “abbreviated Wednesday” at Weston High School, since the afternoon was devoted to a Professional Development Day for teachers. We focused on the subject of interactive whiteboards (IWBs); many of our classrooms have recently been equipped with either… Read More ›
The Strontium-90 Scenario
In all six sections of college-prep Algebra II (taught by three teachers, with two sections apiece), we have just completed a project in which each student has to understand a scenario (written by one of my colleagues), complete some mathematics… Read More ›
Not thinking of YouTube
We’re studying some 20th-Century mathematics in Precalculus class these days. This situation is unusual in high-school math, where most of what we study goes back at least 300 years, not to mention 2300 in the case of most of our… Read More ›
What's wrong with a 92?
This story is completely true; only the names have been changed to…, etc., etc. So I’m handing back a test this morning, using my new system where the grade is written on the bottom of the last page rather than… Read More ›
National Heritage Museum
Barbara and I, along with my sister Ellen, spent the afternoon today at the National Heritage Museum in Lexington. There are two exhibits there that I can enthusiastically recommend, so go see them while you can! The first is entitled… Read More ›
The Global Achievement Gap
Think about this: The most important skill in the New World of work, learning, and citizenship today — the rigor that matters most — is the ability to ask the right questions. Old World rigor is still about having the… Read More ›
Take it easy, but take it.
It’s a cliché to say so, but this was certainly a day that I’ll remember for the rest of my life! Unlike most such days (the JFK assassination, 9/11, etc.) it was historic as a joyous occasion, not a tragedy…. Read More ›
The Wenham Museum
What an astonishing museum! “An undiscovered gem” was how the docent at the desk described it on our way out, and she is right. Barbara and I visited the Wenham Museum yesterday — our first time in Wenham for either… Read More ›
Why Facebook?
So, why do I have a Facebook account if I don’t do anything with it? That’s an easy question. I have a Facebook account because some of my students kept pestering me to set one up. Apparently Facebook is absolutely… Read More ›
The Big Ideas of Algebra, Part Two
This post is a follow-up to my post of November 30, where I brought up two points that can illuminate one’s views on the big ideas of algebra: …we discussed the assignment of partial credit for work in solving a… Read More ›
The inexperienced waitress
The waitress at the Legal Seafoods branch in Harvard Square was nervous and very apologetic. “This is my first time opening a bottle of wine in front of a customer,” she confessed. Of course she wasn’t allowed to rest the… Read More ›
Thesauri & The Man Who Made Lists
I recently read Joshua Kendall’s biography of Peter Mark Roget, entitled The Man Who Made Lists: Love, Death, Madness, and the Creation of Roget’s Thesaurus. While this book is fascinating, it’s also deeply flawed — especially for those of us… Read More ›
How many college recommendations?
I just finished sending off 104 college recommendations this week. How many? Yes, 104. And that was in addition to 21 “early action” recommendations that I sent out earlier in the fall. But before you conclude that that’s a ridiculously… Read More ›
What do I need to do to get an A?
“What do I need to do to get an A?” asks one of my students in an honors math course. I wish I had a magic recipe. I can say with reasonable confidence that it’s possible to get a B… Read More ›
Kindle for textbooks?
One of my students asked me why his textbooks aren’t available for Kindle. Currently the typical Weston student’s backpack weighs 42 pounds*; Kindle weighs only ten ounces! Aside from everything else that’s available for it, imagine replacing your math book,… Read More ›
Obedience
Obedience, by Will Lavender, is a fascinating but flawed novel. Not flawed like Strip Search, which I reviewed the other day; this novel is worth reading. But it’s flawed nevertheless. It shares with Strip Search the characteristic of a great… Read More ›
Strip Search
Strip Search, by William Bernhardt, is an irritating novel. Why do I say that? Well, it’s not just because Bernhardt portrays math teachers as weird and psychotic, though that’s certainly a major part of it. And it’s not just because… Read More ›
Misreading Larry Summers
Continuing yesterday’s theme… There has been renewed interest in Larry Summers’s supposed sexist remarks. When Senator Obama (I almost said “President Obama”) announced that he would appoint Summers to be his senior White House economic advisor, bloggers and others revived… Read More ›
