In 2018 I retired from Weston High School after my 21st year teaching mathematics there. This was also my 44th year as a teacher altogether. Although I’ve retired from Weston, I haven’t retired from teaching: I still teach at Harvard’s Crimson Summer Academy each summer (this coming one will be the 18th!), and I supervise a student teacher through Simmons. For 21 years I taught at the Saturday Course in Milton, MA, and I used to serve on the board of the Dorchester Historical Society.

I read, cook, and spend a lot of time building my model railroad. For some reason I’m left with less free time than would be ideal, considering that I’m supposed to be retired, but somehow I also manage to devote time to my wife, Barbara, and to our excessive number of cats.

  • Another gender difference?

    My impression is that there are significantly more female teen bloggers than male ones, but maybe I’m wrong. A fascinating study by David Huffaker says that “BlogCensus randomly sampled 490,000 blogs to find 40% male and 36% female, with the… Read More ›

  • Homework considered harmful

    Homework can be counterproductive, according to an article on the website. Here are a few excerpts: Instead of improving educational achievement in countries around the world, increases in homework may actually undercut teaching effectiveness and worsen disparities in student… Read More ›

  • Building learning communities

    A conference on Building Learning Communities — right here in Weston! I don’t know much about it, but it’s led by Wellesley’s distinguished former tech coordinator, Alan November, and the blurb looks interesting. Stay tuned for more info…

  • Chris Lydon redux

    Yesterday Christopher Lydon returned to NPR with his new show/blog called Open Source. Day #2 concluded a few minutes ago. Actually, of course, it was only the broadcast portion that concluded a few minutes ago. The Internet portion — the… Read More ›

  • An argument from continuity

    Two sophomores approached my colleague Josh with a question: “How can we construct a fair 5-sided die?” Josh posed a prior question: Is it even possible to construct such a die? He fashioned an interesting argument from continuity: Consider two… Read More ›

  • Intel, security, and Apple

    Paul Otellini, the new CEO of Intel, says that he “spends an hour a weekend removing spyware from his daughter’s computer,” according to a Wall Street Journal article about its recent All Things Digital conference. When asked whether a computer… Read More ›
