A course wiki with tons of great resources on using social media in education, plus how-to and rubrics for many topics.
Using and evaluating discussion forums with students
Second graders first completed a piece of artwork, depicting a place they love to visit or imagine visiting. Then, 9th graders used a Wiki to divide up the artwork. They worked on their poetry and attached it as a comment on the VT. Then, the link was sent to a classroom in Texas, where boys worked to compose an original piece of music for each picture using GarageBand. Overall, it took about 2 1/2 months to put together.
