Understanding social bookmarking
Initially, we began harvesting lists of websites for our benefit. With the end of privatized classroom planning and the move towards professional learning communities, sites began to also offer the benefits of sharing information. You can find a site that best meets your needs as an educator or even as a student. Social bookmarking, or creating cloud-based website bookmarks that you can append tags to, offer tremendous opportunities in the classroom.
Understanding Wikis
A wiki enables communities (professionals or not) to write documents collaboratively, using a simple markup language and a web browser. A wiki is essentially a database for creating, browsing, and searching through information. A wiki allows non-linear, evolving, complex and networked text, argument and interaction.
