Use Visual Tweets to stream twitter feeds to your classroom. The best part is you can monitor the actual Tweet as Accept or Reject before it is displayed.
Start by creating your account and verifying in email. Then connect your your Visual Tweet with your twitter account. Once done provide a Search Term and then click "accept or reject" on tweets you want posted. There is particular URL you can sh
are or post maintaining the display of Tweet feeds, all while you control the management aspect on your computer.
Use this in the classroom to sit in on current event discussions happening around the world.
Iphone and IPad apps coming soon.
An alternative to Visual Tweets is Visible Tweets. Visible Tweets does not require a login, but does not allow you to preview the tweet stream either. It's clean, clutter free, no over head, and as the saying goes "you get what you get and don't throw a fit". Very easy to use, just type in your keyword search and watch the stream.
