Thing 21

Now I know what a Wiki is!  As a collaborative project for a class or group, I see it as being very worthwhile. Each person can add their own thoughts and information.  As it grows, it can reflect the ideas of the group.  As I was searching through wikihow, I noticed there were many wikis for the same thing, with slightly different wording.  I'm wondering, why wouldn't someone edit an existing wiki instead of creating a new one?
The educational website of Hamish McLean (Director eLearning in New Zealand, 5/6 grade teacher) is impressive.  You must be a member of his wiki to enter it.  WOW. http://electroniclearner.wikispaces.com/
What lucky students he has.
One major hurdle in using some wikis is that you don't know if the information is coming from a reliable source.  For medical questions I would  first check the Mayo Clinic website because it is a highy reputable hospital.   I checked "How to be a Kindergarten Teacher" on wiki and it really didn't give consistent, reliable information.  Some how tos work best as a video.  I looked at a "How to do the Breaststroke" on wiki and it looked very complicated.  On my walk this morning I thought I would write a simple wiki on "How to take a Walk".  Surprisingly, there are a lot of them out there, but I'm still going to do it.  Stay tuned!
