With all that we know about the importance of collaborative learning, the use of Wikis as a virtual classroom where students can communicate and respond to each others’ thoughts and ideas is a wonderful educational tool. I love the idea of this “second classroom – one that (is) always open”. I would imagine that with freedom to make posts that are unrelated to the material learned at school, educators would be reinforcing the important understanding that learning happens everywhere and is embedded into everything children do and everything they are interested in.
