Getting the word out on GeoGebra

Maria Droujkova has done some great work putting together some Elluminate sessions on Math 2.0… and she has more to come. On Saturday the 26th she had Markus Hohenwarter, the father of GeoGebra and the chief developer Michael Borcherds on for an hour discussing the past, present and future of […]


As I mentioned in an earlier blog I was at the September meeting of the Math Forum; the theme for the meeting was coaching.There was considerable disapproval of the term coaching; that it set up a hierarchy of ability or skill, that it brought up visions of movie-football coaches berating […]

Respect. It’s not what you think…

I’m an occasional participant at the Math Forum at the Fields Institute in Toronto. It’s a meeting of folks interested in math education research held monthly; I’d get there more but academic and other responsibilities often overlap. Even today I was supposed to be at school for Homecoming but it’s […]

Setting up Ning

School for us doesn’t start until September 14th but I’ve completed all my computer changes for the year (dual monitor, 1Tb hard drive & 500Gb network hard drive, N-router & card, new headphone-mic) and my nephew has gone back home so I’ve got no more excuses to avoid getting down […]

Math Video Markup

As I mentioned in an earlier post, my students will often be required to submit Jing videos of their worked solutions to a variety of problems. Basically it’s the modern alternative to handing in paper copies of their homework but I get their voice, literally & figuratively, describing the solution […]

I think I want to SMAK my kids

I’ve been thinking about how to assess my Grade 9 and 10 students this year … I did a lot of experimentation last year with my accelerated Grade 8 students;they were open to trying things out since acquisition of skills and open-ended problem solving was right up their alley. Here’s […]

Social Technology & Education @ Harvard

Sandwiched between two great motorcycle rides through upstate New York & Massachusetts, I attended the Social Technology & Education conference put on by the folks at Elgg. They held it in the Radcliffe Gymnasium, a former gym converted into a very elegant discussion space.The conference evolved organically: people volunteered to […]

Working Groups

Before I start dealing with reflecting on the content of the classes, I’ve got two more aspects of PCMI to mention.The first is the most productive: The working group. Each of the teachers is assigned a working group in a topic of secondary mathematics for the afternoon (Wednesdays off) in […]

Reflecting on Practice

Once we’re done the morning of math (with a brief coffee break) the teachers all get back together for an hour of math education pedagogy. Like the mathematics we cover, each year is something a little different. For example, in previous years we’ve focused on Lesson Design (with Drs. Nicole […]

The 830 at PCMI

PCMI is a 3 week program; each day from about 830 to 1040 we have what can best be described as a math class. But it’s unlike any math class most people have ever had.Each day starts with its own problem set designed by the class’ organizers, folks from the […]
