Twitter is a micro-blogging tool that allows users to share concise information, similar to a text-message, with multiple people at one time. Users of twitter can post information and access other people's posts using SMS or Internet-based applications. Users can send and receive tweets using a mobile phone, iPod, Blackberry, iPad, the Twitter web site, and even some televisions that have web-based applications. Twitter is often only seen as a social networking tool, but teachers and students are discovering its potential for learning. One application Twitter has for learning is as a communication tool. Classroom conversations can continue between classes using Twitter. Students, and teachers, can also use Twitter as a learning network tool to collaborate, solve problems, and help locate information by asking questions and sharing ideas.
