How should high school teachers engage with Facebook? This NPR story fairly trembles with fright, a barely suppressed cry of "never!"
"Don't ever friend or follow your students on Facebook or Twitter, never post during work hours or using work materials such as a school computer, and certainly never post anything about your job online, especially about students," [New Jersey teachers union spokesman Steve] Wollmer says.
Nothing in the article about any positive features of teaching social media. It's just a zone for possible fails.
