I know that the speech website is frequently used. Especially for students who are more prone to forget where they put a paper they need to have turned in or for those students who cannot remember what time they need to be at a tournament...the speech website is perfect. I also use it as a recruiting piece and a place to put results from tournaments. The speech website has some excellent examples of 2.0 tools that I have found out about via metronet like bighugelabs (the large collage on the front page.)
As for my teacher page, I keep the assignment portion up to date, trying to post as many actual documents as possible for students who are absent or who forget their worksheets at school. I also try to put pictures and videos from class as much as possible. I just posted an animoto video of pictures from our masquerade party!
I think that only a select group of kids uses my class website, but I am okay with that. Unfortunately, those students without Internet at home (I have 3 total based on my start-of-the-school-year-survey) are at a disadvantage. I look forward to the day where ALL students will have some form of Internet access at home...could someone please make that happen??
