I think that Pinterest would be a great resource for students to use to keep their bookmarks to resources they are using on class projects as well. What I love about Pinterest is that it is so visual. You can find exactly what you are looking for and it links back to whatever it is. This year we used dropbox to keep all our resources together but next year I will set up Pinterest as well. I am thinking that it would be a good idea for students to have 3 boards each. One for access to their blogs and videos and other creations, one for resources they gather and bookmarks to assignments, and one for snapshots of artwork and projects that are not online. I will have one as well with links to assignments and resources I want them to use.
We are using IWeb for the sites and blogs and I have them on Mobile me. Somehow with the changeover to ICloud we can no longer publish so we are changing to a new host. The class is still blogging everyday and are eager to upload so I hope our changeover goes quickly so the students have access to all of their blogs to pin the ones they choose to share.
I am thinking of changing from iWeb for next year but I love how all the students can work on their pages at the same time while we only need one site. I don't have to set up separate accounts for each student and it integrates so well with iPhoto and iMovie and YouTube.
