Twitter is a website which offers a social networking and microblogging service, enabling its users to send and read messages called tweets.
Tweets are text-based posts of up to 140 characters displayed on the user's profile page.
The short format of the tweet is a defining characteristic of the service, allowing informal collaboration and quick information sharing that provides relief from rising email and instant messaging fatigue.
Twittering allows you to share information with people that you wouldn't normally exchange email with, opening up your circle of contacts to an ever-growing community of like-minded people.
Using Twitter, you can notify students of changes to course content, schedules, venues or other important information.
You can also old discussions involving all the subscribing students - a long as everyone is following the whole group, no-one should miss out on the Twitter stream.
If you teach international students, you can send tweets in foreign languages and ask students to respond in the same language or to translate the tweet into their native language.
You can also encourage students to find a Twitter ‘penpal’ and regularly converse with them over a period of time to find out about their culture, hobbies, friends, family etc.
