  • How do you organize a binder?

    By on

    Let’s suppose you have to keep a physical notebook (or binder) for a course you’re taking (or teaching, for that matter). Most people seem to prefer using tabs to give themselves the illusion of organization (oops — that shows my… Read More ›

  • “I can’t do math!”

    By on

    In its essence this is a familiar story, but it bears reexamination. We’ll end with the Indian girl who gave up on math at age 15, but we start with the observation that American and Indian kids alike classify themselves… Read More ›

  • Yay! (maybe)

    By on

    Good news and bad news here. The good news is that the Obama Administration seems to have softened its stand on mandatory standardized testing, which has resulted in vastly excessive time spent in many schools and totally inappropriate teacher evaluation… Read More ›

  • JEB @PA

    By on

    They tell us that students should get to know their teachers. So, every year I show my classes excerpts from Kevin Rafferty’s movie, Regular Guys. This is partly so that my students can get a better picture of my own high-school experience and partly… Read More ›

  • Marauder’s Map

    By on

    Harry would be jealous. Look at this: it’s a real-life Marauder’s Map! But instead of showing where people are, it shows where MBTA subway trains are — right now, in real time. How cool is that?

  • Rails across Canada?

    By on

    For the second time, Barbara and I are planning to take the train from Boston to Chicago this April to visit the in-laws…and to enjoy the journey, of course. But that’s less than half the distance across the continent. At… Read More ›

  • The so-called Life-Changing Magic of Tidying Up 

    By on

    What an annoying book! How did it become a New York Times best-seller??? In the words of H.L. Mencken, “no one ever went broke underestimating the intelligence of the American people,” so maybe that’s the explanation. In The Life-Changing Magic of Tidying Up, Marie… Read More ›

  • Why crypto in high school?

    By on

    So I was out to dinner this evening with some old friends — no, not “old” friends in that sense, but “old friends” if you know what I mean — and one of them was surprised that cryptography is effectively… Read More ›

  • X

    By on

    The last time I wrote about Sue Grafton’s Kinsey Millhone mystery series was two and a half years ago. At that point I was up to V. Then came W — and now, of course, X. But this one breaks… Read More ›

  • Hello Ruby

    By on

    Can young kids really learn about coding (which we used to call “programming”)? If so, do they need a computer, or can they learn it better through reading and playing board games? Linda Llukas is betting on “yes” and “the… Read More ›

  • Oliver Sacks redux

    By on

    I’m gradually working my way through most of the oeuvre of the late Oliver Sacks. Two months ago I wrote about Uncle Tungsten, On the Move, and Hallucinations. Now it’s time for The Island of the Colorblind, Cycad Island, and Awakenings. Once again, all three are fascinating and worth… Read More ›

  • Why he stopped doing interviews for Yale

    By on

    Ben Orlin hits the nail on the head in his brief essay titled “Why I’ve Stopped Doing Interviews for Yale.” The whole admissions process for highly selective colleges has become an unpredictable mess, as many of my recent high-school students will tell… Read More ›

  • Copenhagen

    By on

    So…it’s hard to avoid telling a bad joke about uncertainty…you know, “Heisenberg and Bohr walk into a bar…” But I’m going to try hard to stay away from such jokes, Not that the play isn’t amusing. In fact it has… Read More ›

  • The Ophelia Cut

    By on

    You’re probably wondering how many John Lescroart mystery novels featuring Dismas Hardy I’ve read at this point. No, you’re not wondering that? That’s just as well, since I’m not at all sure; there are 14 in all, and they seem… Read More ›

  • What’s wrong with Strunk and White?

    By on

    The Elements of Style, by Strunk and White, is certainly a popular book, but its popularity is richly undeserved. There, I said it. A recent article by Stanford’s Asya Pereltsvaig in the Languages of the World blog explains why the popularity of Strunk… Read More ›

  • “You’re not actually bad at math.”

    By on

    This picture sits atop an interesting article in Slate magazine, titled “You’re not actually bad at math” and subtitled “A new way to think about how to reason.” Although I call the article “interesting,” it’s ultimately disappointing. It raises several… Read More ›

  • A Little Night Music

    By on

    Yesterday afternoon Barbara and I went to see A Little Night Music at the Huntington Theatre. Go see it! Although I consider myself something of a fan of Stephen Sondheim, I had never seen this particular musical before, either on stage… Read More ›

  • Standards of mathematical practice: A portfolio

    By on

    Check out Tina Cardone’s post about standards of mathematical practice. Her suggestions relate closely to my post of August 30, where I discussed the attributes of a good mathematician and how we’re planning to measure them in Weston. There’s a… Read More ›

  • Common bonds…or One No Trump

    By on

    What do these three have in common? Tea-partiers who distrust experienced teachers and blame them for everything that’s wrong in education. Climate-deniers who distrust scientists. Republicans who prefer any of the three highest-polling candidates (Trump, Carson, Fiorina). They’re all right-wingers, of course,… Read More ›

  • Why?

    By on

    What is the key question? Not to sound like Abbott and Costello, but actually “why” is the key question. A year ago, my boss’s boss, Pam Bator — new in that role at the time — started a blog called“Why?” Note… Read More ›
