Wikis are very powerful in the classroom, or more to the point - in creating a virtual classroom. They are the epitome of Web 2.0 and collaboration. I have witnessed some wonderful wikis created by some great teachers to facilitate the collaborative work of their class, communication and feedback with ease (all of the things we would like in a LMS... Editure are you taking note?).
That being said, Wetpaint have let themselves down with the advertising and new requirement to keep a class public whilst inviting in members. To this end I have been experimenting with and promoting 'Ning' www.ning.com. Another advantage of Nings is that they have a Social Network format that students understand but are far safer than Facebook by not including any of the students' private life goings on.
Overall as a reflection, this has been a wonderful course that has opened up so many possibilities in terms of professional development, flexible learning, empowering teachers and reaching out to students with contemporary learning. Well done again to Helen and Diane. Enjoy your break Helen! Watch this space as we develop more courses, taking full advantage of the flexibility of learning with technology.
