The wiki is one of the web 2.0 tools where collaborative learning and active participation occurs.  People with common interests have the ability to publish, contribute, share resources, and build knowledge through engaging in such an environment.  The wiki lends itself to many affordances from the ability to edit content quickly and easily by anyone visiting the page, to all the different versions of pages being accessible.  Participating in a wiki around the affordances of Moodle allowed for intelligent discussions around entries which led to a more intense review process.  I love the idea of knowledge building and how a group can collectively build knowledge together.  I feel today’s learners thrive on active participation in digital and media literacy, and their engagement in wikipedia stimulates intellectual curiosity on many levels.  Peer reviews and debates alone lead to intelligent discussions and thoughtful entries.
