Geometry of the Conic Sections
I posted a fair amount of material about the Geometry of the Conic Sections -- basically my December 5 Asilomar talk, supporting pages and documents, and more or less closely related material.Check it out, and follow the links, as there are quite a few new things to look at! Including Web pages, PDFs, images, and… Continue reading Geometry of the Conic Sections
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
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
Teaching Proof
Last summer, I taught a workshop on "Hands-On Geometry", as part of the Center for Innovative Teaching. It was successful in some respects, but the participants were almost unanimous in letting me know I had not managed to get across the "authentic approach to proof" I had promised in the course description. Part of the… Continue reading Teaching Proof
