In yesterday’s Boston Globe there’s an interview with Bob Sternberg, psychology professor at Yale, president of the American Psychological Association, and newly appointed dean of Arts and Sciences at Tufts. Globe correspondent Peter DeMarco asked him about the use of… Read More ›

Sudoku revisited
I now think my theory about Sudoku in the Globe is wrong, or at least needs to be tweaked: IMHO yesterday’s puzzle was a lot more difficult than today’s.
Wikipedia
My current favorite resource on the Internet is the Wikipedia. Considering that anybody can write and edit its entries, I am astonished that this enormous site could be not only so comprehensive but also so reliable. Of course it contains… Read More ›
Doing something about stress
Be sure to read Anand Vaishnav’s article, headlined “Suburban high schools try to ease up on teen stress,” in today’s Globe. My favorite paragraph quotes former Lincoln-Sudbury colleague Charlie Ruopp, now principal of Wayland High School: Wayland High School tried… Read More ›
Math for democracy
I highly recommend “Mathematics and democracy: the case for quantitative literacy,” published by the National Council on Education and the Disciplines. What they’re calling “quantitative literacy” is very close to what we call “quantitative reasoning” at CSA. This online collection,… Read More ›
Straight as an arrow
Too many students (and too many parents, and even some teachers) view the process of learning math as a one-dimensional arrow, in which the courses come in a fixed order and lead inexorably to calculus and beyond. The most successful… Read More ›
It ain't fun if it's easy
An article in UMass Boston Magazine, Volume 9 Number 1, introduces Rick Jensen, the new head of the UMass Center for Environmental Health, Science, and Technology: Roderick (Rick) Jensen sees puzzles everwhere. When his daughter told him in second grade… Read More ›
Two wonderful mathematical puzzles
I’ve recently been stretching my skills with two new mathematical puzzles, Sudoku and Planarity. Thanks to the Boston Globe and other papers, Sudoku has now become quite popular. Although the Sudoku page claims that it’s non-mathematical, these puzzles actually involve… Read More ›
Public school hours & college curricula
As chair of the Library Committee of the Dorchester Historical Society, I spend a few hours each month working with some other volunteers to catalog our collection of historic documents. Today I catalogued an immense 5-volume history of the local… Read More ›
What's wrong with UMass?
Many — probably most — of my Weston students look down on UMass Amherst. Certainly it’s not the choice of our most successful students. I heard one junior disparaging it to the extent that he would consider his life ruined… Read More ›
Neurological benefits of blogging?
Neurologists Fernette and Brock Eide analyze the Brain of the Blogger. Here are some of their claims: …our mental activities actually cause changes in the structures of our brains — not only what we think, but how we think as… Read More ›
Blogs in the math classroom?
Blogs are public writing. We want our students to publish their work — to take ownership of it, to take personal responsibility for it, to take pride in it. These goals apply not only to English class but also in… Read More ›
Adequate Yearly Progress
A Boston Globe article on October 3, 2004, included Weston High School among the schools cited by the Department of Education for failure to make Adequate Yearly Progress on the No Child Too Far Ahead Act. Sorry, I mean the… Read More ›
The Achievement Gap
Yesterday I wrote about the pressure to take honors math, but I didn’t even consider the reasons for this pressure. The implied one — which I tried to debunk — was that honors math is necessary in order to get… Read More ›
Misanalyzing textbooks
The Washington Monthly publishes an interesting example of the lies about incorrect analysis of math textbooks by right-wing zealots. Not that I’m a fan of very many textbooks, but a little truth would help.
Honors math courses
Weston, of course, is really Lake Wobegon, where all the children are above average®. Weston’s only public high school has just two levels of math courses: the higher level is called honors, the lower level college-prep. Everyone is above average…. Read More ›
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 ›
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 ›
