How to maximize the benefits of Course Evaluations.
For Algebra: My response to Temple Grandin’s “Against Algebra” article in The Atlantic.
Updates to my Math Education Page
There Is No One Way: I combined several blog posts into one article in which I argue for teacher eclecticism, and share a pedagogical framework of sorts.
I tweaked and updated Geometry of the Conic Sections — including four different GeoGebra constructions.
I added 12 videos about the Lab Gear for teachers, a free at-home professional development program. I added a Lab Gear Q and A page, and reorganized the Lab Gear home page. I expanded and updated the Algebra Manipulatives: Comparison and History page.
What else is new
27 November 2022: I restored the graphics for Unexpected Ratio.
17 September 2022: I presented “Geometric Puzzles for All Ages” at the Florida Math Circles Network online conference. Handout, with lots of links.
18 August 2022: I sent out my e-newsletter, with links to recent blog posts and new material on my website.
27 November 2018: I moved my blog into WordPress (here.) I thought the move had happened smoothly, but some graphics, and some entire posts, failed to materialize. Also, many links are broken. If you come across these problems, please notify me, indicating which post had the issue. Thanks!
I have retired from the classroom after 42 years as a math teacher in K-12 — from counting to calculus. I now work with teachers and schools: Math Education Consulting
