I just started reading your blog. I am a Spanish teacher. I am interested in how you use Twitter for lifelines during tests. Sorry, I'm sure you posted the details already. Do students just get to use it once? Do they get to ask for help once and receive it once? How else do you use twitter besides for tests?
A bunch of folks have asked me recently to highlight somewhere on the site a series of Twitter-related posts.
Well, I've done it. Now available on the sidebar of teachpaperless.com, right below the 'Most Requested Posts' is a series of posts related to using Twitter in the classroom.
