A Coleman Blank?

I am doing some research and am reading David Coleman’s 2011 talk to NYSED regarding the common core standards.
This is the nysed.gov link to the full transcript I am using. When I get to the part where he says
But it also involved quite wonderfully several other teachers of every stripe from every organizational background who are involved in developing these standards and also of course the NEA and other groups. But if there’s one voice that is loud and clear here, it is the voice of teachers. And let me tell you what we learned as we listened to those voices. (p.4-5)
It is followed by a large blank area before going on to the next section, with no mention of what David learned as he listened to actual educators. Did he not learn anything, or was it like the “listening tours” that happen from time to time-where people were talking but it didn’t really impact the process?
If he did learn something, I would like to know what it was. If there is a better link, or more information, please share it with me.

Thank you,
Dan McConnell
