RE: education, technology & chat (The Mathematics of it)
Hi Peg and others,
I have loved this discussion but I may confess that is not in my ZPD.
So, I guess I may have missed lots of things because speakers here are
like the Tolstoian characters at the end of Thought & Language
communicating a lot without enough speech. I also assume that some of
you know each other personally, which makes thing easier to understand
because it looks like there are lots of thing that are follow ups of
other discussions. (Coming back at the issue of Stalkers at XMCA...) May
be you want to recommend some reading for starters? Also, are there
similar discussions concerning the teaching of language?

Wow in the portland schools, huh? Terrific.
Can you get operations and their models with their strategy variants
into the stream as problems of equality of measured continuous quantity
(free of numbers)? A > B (Jenny's amount of clay is greater than
Sasha's and it isn't fair) so how do you get A=B but by getting some C
so that A-C and
B+C. From clay models to drawings of it to lines about it to letters
it -- and you can model all the different operations situations that
Siegler and his folks get into. There is no doubt that numbers will
creep in too soon because non-continuous quantity entities will, but at
least there is some escape from a put-aside unit for measurement, maybe?
