The highly efficient paper-and-pencil algorithms that have been traditional in the U.S. may no longer be the best algorithms for children in today’s technologically demanding world. Today’s elementary school children will be in the workforce well into the second half of the 21st century and the school mathematics curriculum should reflect the technological age in which they will live, work, and compete.
I’m not sure what that means. That kids should use calculators all the time? Or something quite different?
Isaacs defends spiraling:
Research shows that students learn best when new topics are presented at a brisk pace, with multiple exposures over time, and with frequent opportunities for review and practice.
The program offers more supports for teachers and parents, he writes.
Lots of comments, including a response from Garelick on whether research supports EM’s effectiveness.
