I added a paragraph to the Abstract Algebra Teachers' Guide, just in time for my NCTM presentation in DC. I'll be speaking on my Space class, and expect at least some of the participants in my workshop to head to that page on my site.
The talk is Saturday, April 25, at 12:30 p.m., during the very last session of the National Meeting. Something tells me many potential participants will actually have already turned into tourists at that time. Oh well.
