My class just finished researching Thailand.  One more piece that I want to add so we can continue our learning and really connect to this other culture is by having a wiki with another 2nd grade class in Thailand.  I thought the other day that our 2nd grade teacm of 7 should have a wiki.  I was contacted by our enrichment person about preferred dates for a field trip.  It would have been so much easier and more effective if I could have put the info on a wiki and let the other team members post their thoughts.
