On the internet, nobody knows you're a dog

I'd forgotten that!

Maria Konnikova mentions the cartoon in an interesting piece about online comments.

I've always been amazed by kitchen table math commenters. Smart, funny, and civil for years on end.

instructivist just reminded me of the old Wit and Wisdom page.

It's great.

dept of greatest hits: how to spell part 2

I don't know if I knew what constructivism was when I wrote this post about the Mapleton Teacher-Research Group in June 2005. (hit refresh a couple of times if the post doesn't come up) I'd heard of "fuzzy math," obviously, but I don't think I realized that the entire country, including my own district, was undergoing sweeping constructivist "reform," and had been for some time.

I certainly didn't know that ed schools had been teaching nothing but constructivism since the 1980s.

I found out about the Mapleton Teacher-Researcher group when I picked up a copy of their book, Spelling Inquiry, at the K-3 school here in Irvington and started leafing through it.

That should have been a sign.

I was looking for the old Lucy Calkins posts on ktm-1, and I found this post on character education in Irvington.

You must read it!

Especially the comments thread.

one comment: Doug Sundseth wins the award for highest degree of arcane yet serviceable knowledge.

Unfortunately the whole thing ends with a splat (goofy speculation on evolutionary history as it pertains to enrichment in an affluent suburb).

Stop reading after the medieval peasant costume and you'll be smiling.
