The personal learning network for educators
Immediately make the parents a part of the process by having them use some of the Web 2.0 tools. Each session should definitely be captured and shown. Once you get some parents directly involved it will be become contagious. I would suggest starting with the leadership of the school PTO and build from there.
You can use some of the sites on my Web 2.0 page http://cybraryman.com/web2.0.html to explain Web 2.0 and take it from there.
