I'm also doing my master degree on a similar theme, mine is about how
can an art teacher integrate internet into their classroom (here in
Portugal). From what I have understood over here, the main problem is
the lack of education for art teachers on how
it can be used effectively in an art classroom.
Dr. Craig Roland: http://arted20.ning.com/ is a great suggestion, I'm
also there! It has been a great help for my theses, including his book
"The art teachers guide to the Internet".
