Twitter is a free service that lets you keep in touch with people through the exchange answers to a simple question. What are you doing? Where's the next workshop? Twitter has become a popular microblogging tool. It can be accessed a variety of ways, such as via the web or instant messaging services. Why is it useful for educators? Consider these possibilities:
1. Quick networking: Your one question may draw responses from a host of people quickly. If you have a relatively good number of fellow educators in your contact base, some of them are bound to be checking their twitterfeed when you pose your query.
2. Knowledge sharing: People are eager to answer questions because they can also learn from the shared experience. It's a quick way to find a URL to a classroom activity or information about an educational event, for example.
3. Track conferences: Twitter can help you stay on top of what's going on at conferences. If you can't attend one, someone may be tweeting about a session. Or, as often happens, you are at a conference but several great sessions are happening concurrently. A tweeter buddy can fill you in. To avoid multitasking during an important presentation, you can can check the conference tweeterfeeds later.
