Web 2.0?

I feel like many of the web 2.0 tools we talked about are already being used to promote education. Facebook, for example, is being used by schools, teachers, TA's, and other academic institutions to relay important information to students. Teachers can post assignments or resources/links on a class facebook profile. BYU uses facebook in conjunction with the tool Blackboard. Blackboard itself is a web 2.0 tool! It really is all around us, even the lowliest of internet users. The internet is becoming more and more necessary for education, and it has also become a popular form of leisure. Education facitlities around the world are realizing that they can be more effective in teaching if they link all of these tools together. If the student will already be on the internet looking up information for a project, why not post additional information on something like Facebook which will inevitably be visited in the course of research?
Other sites like Youtube are also being used already. Many of the teachers of dance classes at BYU record dance performances and assessments with a camera and post them to a special channel. The student is then able to view their dancing and listen to the feed back of the teacher to better know how to improve. This could be applied to any subject in a variety of ways.
