Social Media

Email
 has been around for almost two decades and has served us well. Through email, we stay connected and share information and documents. It would be difficult to conceptualize our work without it. Yet, the internet has evolved over the past two decades from a place one visits to a place in which one interacts, offering new opportunities beyond email. Numerous web resources such as social bookmarking, social networks, RSS aggregation, blogs, and Twitter can be used to keep school board members, administrators and teachers up to date on emerging technology, teaching resources, and support networks. This session will provide an overview of Web 2.0 applications for personal learning and instructional use.

Social bookmarking
IT is a method for Internet users to organize, store, manage and search for bookmarks of resources online. Unlike file sharing, the resourcesthemselves aren't shared, merely bookmarks that reference them.

Social Network
A social structure made of nodes that are generally individuals or organizations. A social network represents relationships and flows between people, groups, organizations, animals, computers or other information/knowledge processing entities. The term itself was coined in 1954 by J. A. Barnes.

Blogging
Blogging is the verb (action word) that has been coined by people to refer to the act of adding an entry or entries to a blog. Those that actively engage in blogging write entries almost hourly, but there is no rule for how often a blog entry must be added. It is entirely up to the individual.
A blog is a lot like a journal except it is generally intended to be read by others. The topics for blogs vary greatly; some being about day to day activities and others taking a more corporate or political slant. There is no defined or widely accepted format and so blogs range from one liners that the author adds every few hours to relatively long, well thought out arguments for or against a topic of interest.
Usually, users that are interested in a particular blog can subscribe to the blog and receive updates automatically through the use of an RSS feed aggregator (also known as a news aggregator). Unlike mailing lists, you do not need to provide an e-mail address and if nothing else, blog subscriptions protect your e-mail address from spam.
