Popplet is like wallwisher...hopefully works better. I have used wallwisher, but there seems to be lots of glitches when my class tries to access the wall. Popplet is an alternative, and much like Wallwisher meets Prezi.
Awesome list of Web 2.0 tools - list of tools that can be used and notes on each one that allow teacher to see uses in the classroom. Great list to reference
Awesome site for Blogging - things to remember when teaching students how to respond. There is even a pdf file available that the teacher has created. On this paper, students are given sample blog responses and discuss whole class whether they would approve the comment.
I wish I would have seen this post yesterday. I had to reteach blogging to our book club group. Mainly, I feel the time constraint/computer issues we had the first two weeks set us back. However, I did something similar to this actually handwriting responses on the white board. The number of posts and details within the post increased dramatically.
