Asilomar Notes: Story Tables: A session where I learned about a phenomenally powerful tool to teach about functions.
Asilomar Notes: Tech: Two interesting sessions involving the use of technology in the teaching of math. Read my notes and reactions.
On the Desire to Push Kids Ahead: A guest post by Rachel Chou about hyper-acceleration.
New on my site
A conic sections home page. (Links to the geometry of the parabola and ellipse, 2D and 3D, and more.)
What else is new
On December 1, I attended the California Math Council Northern Section meeting in Asilomar. My presentation was about Reaching the Full Range of students in a heterogeneous class (i.e. any class). I put lots of links about this on my Talks page. See above for links to blog posts about sessions I attended.
On November 27, I moved my blog into WordPress (here.) I thought the move had happened smoothly, but I just noticed that some graphics, and some entire posts, failed to materialize. Worse, the graphics also vanished from the old Blogger platform! I will try to fix this as best I can in the next few weeks. If you come across this problem, 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, and I continue to develop curriculum.
On this page: announcements about new material, updates, etc. on the site; new publications; my appearances at conferences; and my other activities in math education.
