After completing my very first wiki within my masters program and within my class, I feel much more confident and comfortable with the collaboration tool and the process.
I now know that only one person can modify or edit a piece of information at a time.
I found this out the hard way when I had my class add their biography information to a wiki and they all chose to modify the exact same template at the same time. Whoops. Now I know to include specified spaces for their new information.
I love the idea of a wiki. I am just trying figure out how to use it more effectively in my classroom on a more regular basis.
