dsummar, patience is the key. I've been responsible for it at my school for a little under 3yrs now and its a slow process selling the idea to colleagues. I set up small working groups (10-12 staff) of interested staff and then used a trickle feed / cascade training model
during the recent snow days we have had, staff put work up for students to do - in 4 days, we had almost 13000 hits, with an average of 7 subjects per student accessed
all the VLEs on offer are much of a muchness I have found. this one offers the collaborative aspect of learning, and is good from a learning and teaching point of view
have a look at our site if you would like - search for Maiden Erlegh School on www.School-Portal.co.uk**** (I'm in the process of redesigning our homepage so ignore that bit!!)
