Very interesting website I thought. It is also a great way to look at another way of integrating ICTs into the classroom.
I would envisage a resource like this to be something used over several lessons and something that the students get to used to working so that the technology side of things does not get in the way of valuable learning time.
I am hoping to be able to get some spare time to have a really good look at the website.
Its a shame I only just found it now at the end of my prac placement.
