Last summer, as part of the Center for Innovative Teaching Tech Symposium, I gave a talk on the use of computers in math education. The audience was school leaders (administrators who focus on educational leadership), not math teachers, so I had to take a couple of steps back, and think about the question in terms… Continue reading Computers in math education

Asilomar talk
I'll be speaking about "the geometry of conic sections" at an upcoming conference*. Perhaps I'll see some of you there?I added the info to my Talks page, but have not yet uploaded all the corresponding materials. The site so far only includes the geometry of the parabola. I'll be adding bits about the ellipse and… Continue reading Asilomar talk
Ordering Lab Gear
I've been receiving more e-mail from teachers who have trouble finding a way to order Lab Gear... It is actually not surprising: I just tried Google, and it really didn't work to get me to the Creative Publications page.I'm sorry this is not more straightforward. Creative Publications is a shadow of its former self, and… Continue reading Ordering Lab Gear
Worksheet Tweaks
Because of feedback from participants in my "No Limits!" workshop last summer, I tweaked some worksheets:- Graphing Square Roots- Quadratic Forms- A Different Approach to the Quadratic Formula(The latter two can be found on the Parabolas and Quadratics page.)--Henri
More Small Changes
I added the "function diagram dance" activity to the Function Diagrams main page. I also added to that same page a list of the function diagram lessons in Algebra: Themes, Tools, Concepts (ATTC). Those sometimes duplicate, sometimes complement the other function diagram material on the Web site.I added an "index of selected topics and tools"… Continue reading More Small Changes
Small Changes
In part as preparation for my summer workshops, I've been making small changes here and there:- updated many references to the site's address to MathEducationPage.org- added a document that outlines a suggested sequencing for Lab Gear lessons- added a construction challenge to Geometry of the Parabola- added a reference to Keith Weber's excellent article "Teaching… Continue reading Small Changes
How One Learns
I've been catching up on back issues of The Mathematics Teacher. Great quote from October 2008, opening an opinion piece by Gregory Freeman and Lisa Lucius:"I learned to ride a bike at age six. The experiences leading to my first solo bike ride are still vivid memories. First, my father gave a wonderful explanation of… Continue reading How One Learns
Using my materials in workshops
Once in a while, I get a request for permission to use some of my materials as part of a teacher training workshop. Here is the general answer.If the material is from one of the books whose copyright is currently held by a commercial publisher, I believe the rule of thumb about fair use is… Continue reading Using my materials in workshops

No More 3D Lab Gear?
A correspondent tells me that the 3D Lab Gear is no longer available from Creative Publications. (You'd think that Creative would have notified me, but to them I barely exist anymore.) The correspondent adds that non-3D, "regular" Lab Gear is still available by phone or on line.Unfortunately, I can't suggest an alternate source for the… Continue reading No More 3D Lab Gear?
