Wiki's and P.E??

So, of course when we started discussing/working on wiki's I immediately wondered how they could be applied to middle school P.E. and health. At first I thought, "well, maybe only in my health classes." But after a bit more thought I realized that utilizing wiki's would be a great way to bring together collective knowledge and rules about various sports and even fitness concepts. Although one student may not know EVERYTHING about a particular sport or activity, chances are that he/she knows a couple of facts. Therefore, if my students were to use wiki's (as we are now in the ITS program), I think they could possibly have a sense of ownership over something that they helped produce. In turn, it could be a reference that all students could use to understand various activities that we participate in throughout the school year. What are your thoughts on this??
