Here's an article on teacher weblogs and some of the controversy surrounding the phenomena. The lines of free speech and the public good can be fuzzy and it seems that across the country school systems are responding differently.
Here's a poignant sample:
Lisa Cooper, 44, a teacher in Atlanta who blogs under "elementaryhistoryteacher," says her blog helps her gather her thoughts and speak for herself.
"As a teacher, I feel like people don't listen to me. Parents don't listen to me, politicians don't listen to me, the media doesn't listen to me — but everybody tries to tell me how to do my job."
I feel ya.
