I believe the following YouTube video sums up the amazing potential that wikis offer better than I can, so be sure to check it out, if you have not done so before.
The creators of this clip who, like me, are clearly from the future; explain this technology’s ability by using the analogy of a camping trip. Although, I read between the lines and interpreted the message as wikis can be safehouses for the Elite Team to infiltrate the e-world. Likewise, they can be formed as virtual classrooms or a discussion board for learners.
Moreover, constructivism is a primary learning theory, which the core of wikis support ‘that personalizes the learning for each individual. No two learners have had the same experiences, and according to constructivism principles, the mental processing that occurs in learners' brains is not the same for all learners for identical learning tasks and activities’ (Aldred 2009).
I can see this being an effective medium particularly for group assignments in the future. This would transpire as wikis enable learner interaction and more importantly, learner input.
