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.

  • Intellectual growth

    I’m examining an Algebra II book that looks really good so far (Discovering Advanced Algebra: An Investigative Approach, by Murdock, Kamischke, and Kamischke — if you’re interested). But a statement in the Note to Teachers got me thinking: Students will… Read More ›

  • Listlessly

    It has been so hot and muggy that the cats are just lounging around listlessly. Which means…well, the word seems to suggest that they don’t have any lists. I’ll admit that cats aren’t big list-makers (though they are otherwise fine… Read More ›

  • Phys Ed online?

    OK, we’ve heard of online math courses and writing courses, but phys ed???? Even as I type this, I’m listening to a report on NPR about the online phys ed option for students in the Minneapolis Public Schools. Hmmm….

  • Comfort levels, parties, & structure

    Ordinarily I don’t feel very comfortable at parties if most of people are unknown to me. When most of the attendees are friends of mine, I’ll enjoy the party, but my comfort level goes down as the number of strangers… Read More ›

  • Helpful volunteers

    Three of my sophomore students have volunteered to set up a website for use by our Math Team. They’re designing a database to contain Math Team problems and answers collected from the last n years, typing many hundreds of problems… Read More ›

  • Notes on a textbook

    This note, written by a junior, was attached to the precalculus book she was returning: Dear Mr. Davidson, Here is my book. I have enjoyed it thoroughly. I read it when I was feeling down, and it raised my spirits…. Read More ›

  • Life after exams

    It’s tough to keep kids focused and engaged after they’ve finished their final exams. As I blogged earlier, our math exams were on the 14th… but school continues until the 23rd! Everyone knows that tests and grades are all that… Read More ›

  • Fermat's Last Theorem limericks

    Weston High School held a math haiku contest, but maybe we should have had a math limerick contest instead. Here are some math limericks about the proof of Fermat’s last theorem (from a contest held at the University of Illinois… Read More ›
