Integrating the High School Math Curriculum: How I rearranged the program at my school, moving various units up or down the grades, to get away from the problematic Algebra 1 / Geometry / Algebra 2 sequence.

The California Math Framework Revision: The new Framework, due in 2022, aims to improve math education for all students by way of curricular and structural changes. What about pedagogy? I share my reactions to the Department of Education’s FAQs.

Commitments: As teachers, is our commitment to mathematics? to our students’ learning? or to enforcing student compliance?

Updates to my Math Education Page

I added a page on Big-Picture Planning: thoughts on how to map out a program, a course, a unit.

I added yet more evidence that all parabolas are similar on my Geometry of the Parabola page. This time a GeoGebra figure showing that given two parabolas with parallel axes of symmetry, one is a dilation of the other.

I added four GeoGebra applets: games to help students’ understanding of signed number arithmetic. (Note that the Snap! version of the games is currently unavailable.)

Other News

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!
