Check out the blogs for all of my classes! We rotate each day that a class meets, so that students take turns posting class notes. So far this has led to a number of positive effects: Students who miss class… Read More ›

Little Brother
Little Brother, by Cory Doctorow, is billed as a “Young Adult” Novel. And so it is. But, like several other “Young Adult” adults, it is worth reading by not-so-young adults. This is an homage to 1984 — hence the title… Read More ›
The Internet isn't melting our brains.
Vincent Rossmeier has written a refreshing article in Salon entitled “Is the Internet melting our brains?” Essentially an interview with linguist Dennis Baron about his new book, A Better Pencil, the article counters much of the typical hand-wringing in the… Read More ›
povo.com
How nice to see a website that actually recognizes Dorchester as a neighborhood of Boston! Povo not only lists it prominently, but its description is an accurate portrayal of Dorchester’s many virtues: Dorchester is the largest geographic and most populated… Read More ›
Everything is Miscellaneous
For years now I’ve been fascinated and bothered by hierarchical systems of organization, starting with the Dewey Decimal System and progressing to typical org charts in businesses and hierarchical file systems on computers. On the one hand, the systematic structure… 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 ›
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 ›
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 ›
Wordle
I just discovered a cool poster-creating applet called Wordle. In their own words: Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source… 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 ›
iPhone games
Having been an enthusiastic iPhone user for the past four months, I’m not surprised that many of my students want to play games on it (at least those students who don’t have iPhones themselves; this is Weston, after all). That’s… Read More ›
Turn your iPhone into an ocarina.
I recently installed an unusual application on my iPhone: Ocarina. This program turns your iPhone into a four-hole ocarina, with the holes outlined on the iPhone’s touch-sensitive screen. But the really cool thing is that you actually blow into your… Read More ›
"Everyone else does it."
The Josephson Institute Study of the Ethics of American Youth has been widely reported on such widely varied outlets as National Public Radio, Fox News, and Yahoo News. They report “a troubling picture of our future politicians and parents, cops… Read More ›
Meme abuse
What’s a meme? Well, those of us who have spent too many years on the Internet (from its inception in 1969, actually, when it was called the ARPAnet) and those of us who have read The Selfish Gene, by Richard… Read More ›
Teaching RSA in high school
By this point I’ve taught simplified versions of the RSA algorithm to ten different cohorts of teens: four years’ worth of Honors Algebra II students at Weston High School, juniors for four summers at Crimson Summer Academy, and two years’… Read More ›
Technology in school
No, this isn’t another one of those essays about the usefulness of technology in teaching math. This is a response to a fascinating post in Heather’s Comparative Childhood blog, in response to a newsletter from her daughter’s middle school. Here’s… Read More ›
Double Vision
I have just finished reading Double Vision, by Randall Ingermanson. This science fiction thriller has a great concept, but the execution is disappointing. On the plus side, the novel speaks effectively to those of us who have worked in the… Read More ›
How to create a blog
In one of those typical synchronicities, two of my students have just asked me how they can create their own blogs — a Weston sophomore yesterday, and a Saturday Course fifth-grader today. The Weston student suggested that I should post… Read More ›
Goodbye, Arthur C. Clarke.
Another of the great ones is gone. Scientist, science fiction writer, and visionary Arthur C. Clarke died the day before yesterday at age 90. He is best known for the novel 2001: A Space Odyssey, on which the eternally rewatchable… Read More ›
