Web 2.0 in the classroom

A great web 2.0 tool for the classroom is google docs. In fact, google has an entire blog dedicated to using google docs in the classroom. Teahcers can have students work collobartivly on a class document or project, can produce tests or surveys using form, or use any of the hundreds of templates created by teachers and google for the classroom.
A second web 2.0 tool that can effectily be used in the classroom are class wikis. Wikis allow for multiple users to edit and add information. Classes could create wikis similiar to wikipedia, which is a public encyclopedia edited by the public. Classes could also create wikis to keep track of classroom house keeping, such as topics being covered, schedules, etc.
