  • Happy numbers, unhappy families

    By on

    One of my students came across the Wikipedia article on Happy Numbers and asked about it in precalculus class. This is the sort of topic for which Wikipedia is an excellent source; in fact, if I wanted to know about… Read More ›

  • An ethical dilemma

    By on

    It is unethical, as I’m sure you know, for a teacher to reveal any individual student’s grade to another student. (Students reveal their own grades all the time, of course, but that’s their decision, not ours.) This principle placed one… Read More ›

  • A Stab in the Dark

    By on

    Lawrence Block’s 1981 Matthew Scudder mystery, A Stab in the Dark, has recently been reissued in audiobook format. If you’ve only read some of the recent Scudder novels, where he’s a non-drinking alcoholic, you’ll find that A Stab in the… Read More ›

  • Maybe we should try this in high school

    By on

    Rudbeckia Hirta, the pseudonymous math professor from a state university in the south, recounts a story with a delicious little idea at the end: So today I saw one of the football players in the class sending text messages on… Read More ›

  • Wikipedia revisited

    By on

    My students have had a hard time finding any errors in Wikipedia (one of their assignments). Of course there are plenty of errors in it, so why was it so hard to find them? I think the issue is that… Read More ›

  • Romantic pairings: inappropriate for high school?

    By on

    No, it’s not what you think. Of course there are romantic pairings in high school, and there’s no point in considering them inappropriate. But that’s not what this post is all about. The question is whether a precalculus class that’s… Read More ›

  • Watch Your Back!

    By on

    I recently read another funny novel by Donald Westlake, Watch Your Back!, and I can recommend it to anyone with a sense of humor. Though nominally in the thriller genre, this entrant in the Dortmunder series manages to combine convincing… Read More ›

  • Once again, addressing the achievement gap

    By on

    We had a day-long workshop last week on the achievement gap, which I’ve discussed in various earlier posts. What troubles all of us is that our black and Latino students (mostly from Dorchester, Roxbury, and other Boston neighborhoods) get significantly… Read More ›

  • Cruciverbalism

    By on

    If you have any interest at all in crossword puzzles, you will definitely enjoy Cruciverbalism: A Crossword Fanatic’s Guide to Life in the Grid, a small but well-written book by Stanley Newman and Mark Lasswell. Fascinating, amusing, and full of… Read More ›

  • Arsenic and Old Lace

    By on

    Arsenic and Old Lace is definitely a classic film, so that means I’m supposed to like it — right? I don’t know why I had never seen it before, but I finally got around to it the other day. Unfortunately… Read More ›

  • Off by two ems

    By on

    There’s a flaw in the typography of the sign outside my dentist’s office. It’s neatly lined up in two columns, starting something like this [names changed to preserve anonymity]: John Smith, DMDMary Jones, DDSJoe Gummer, DDSRhonda Radical, DDS    General DentistryDental… Read More ›

  • The Rottweiler

    By on

    The Rottweiler is another excellent book in Ruth Rendell’s collection of thrillers (as distinguished from her Wexford detective novels). There is a richly developed cast of characters, including one who is the favorite suspect of the police but who the… Read More ›

  • Excellence without a Soul

    By on

    I highly recommend Excellence without a Soul: How a Great University Forgot Education, by Harry Lewis. Though nominally about Harvard, it’s really about a much larger domain, including not only elite universities but also elite public high schools such as… Read More ›

  • Somersault

    By on

    We tried to watch Somersault, acclaimed all over Australia. It looked like it might be of interest to film buffs and to anyone who works with teenagers (or anyone who has a teenager in the family). But neither Barbara nor… Read More ›

  • 7+2=10

    By on

    I just came across this clipping I had saved from the Boston Globe some years ago. Unfortunately, I don’t know the date, and it’s not really worth the trouble researching it. It quotes Joe Cazazza. who has finally retired from… Read More ›

  • A Madman Dreams of Turing Machines

    By on

    Too often the books I review are mysteries (or novels in related genres, such as psychological thrillers). But not this time (and not next time either). Today we’re talking about a straight, mainstream novel — more or less. As you… Read More ›

  • Hey, Verizon, $.02 does not equal .02¢

    By on

    You have to listen to this actual mind-boggling conversation between a Verizon Customer Service manager and a Verizon customer. Here is the first astonishing excerpt: Customer: Do you recognize that there’s a difference between point zero zero two dollars and… Read More ›

  • “Don’t think about thinking, it’s not on the test”

    By on

    On NPR’s Morning Edition today there was a story about education and standardized testing, which included a debut performance of “Not on the Test” — a “gentle lullaby for students across the country” by Tom Chapin and John Forster. Do… Read More ›

  • New Year's Eve at the Ashmont Grill and High Fidelity

    By on

    To celebrate the New Year, Barbara and I just had dinner at the Ashmont Grill, which offered a special menu for New Year’s Eve. Although we hadn’t really intended this to be a “going out in public” experience — like… Read More ›

  • Somebody Else's Music

    By on

    I just finished reading Somebody Else’s Music, by Jane Haddam. One of the best in her Gregor Demarkian series, it is distinctly darker than its predecessors. Most interesting to a high-school teacher is its theme of high school as real… Read More ›
