I've had the students create their blogs on the schools intranet worpressMU
installation. So far I've got 25 of 60 blogs set up. Their were/are some minor problems, but I will get them all a blog eventually.
I had student reactions ranging from this is very cool ... all the way to you can't make us do this. It is math class and some of them are excited about reading and blogging and some not so much.
My blog about the book I'm reading: History of the Western World; lives here Russell Study
The idea is to have the students read books that they would probably not read on their own and give them another point of view on mathematics, philosophy, and physics that they do not typically get in a traditional classroom. They make blog entries about each in class reading with vocabulary words extracted from the readings.
