Our thanks to Dr. Garofalo for speaking to us about this fascinating application of technology in mathematics teacher education. To help carry-on the discussion on this blog, I pose the following questions:

• Why were students able to understand math better using these software applications than with more traditional methods?
• What was it about the technology that facilitated the learning, beyond improved math pedagogy?

We had discussed this a bit during the Colloquium, but now that we’ve had more time to think about it, perhaps some of you have more to say.
