Wikis are a 21st century learning tool because they enable us to share documents. They facilitate and encourage communication amongst colleagues (or peers) without requiring that everyone be in the same place at the same time. For instance, our school has a technology wiki that allows us to see availability of materials, spaces, and resources for integrating technology in our lessons. Because this is a shared space, we can ensure that we are not doubling-up on usage or space, and everyone can be on the same page in terms of sharing their plans with others. It eliminates the need to send multiple emails to the staff, and it is easily changed and viewed with just a few simple clicks.
