why, yes, I do have a blog

Slowly, surely, the old media is catching up with teachers using the new media to spark learning.

Teachers use blogs, or online journals, in different ways. Some post homework assignments and links to relevant Web sites; others describe key events of the day to keep parents in the loop. Most commonly, students post written responses to a teacher's query.

When students read each other's blogs and make comments, "the work becomes a conversation instead of a one-way delivery of information," said Warlick, a former teacher who wrote "Classroom Blogging: A Teacher's Guide to the Blogosphere."

Eventually, they'll catch up to blogging teacher-activists, too.
