Noel Jenkins, the innovative Geography Advanced Skills Teacher and sharer of great ideas and resources via Digital Geography and Juicy Geography, has written a guide. He, like me, has been using Google Apps for Education with his students and has found it to be really beneficial. I think it’s a potentially free VLE replacement.
The Google Apps for Education guide Noel has written can be found here. Whilst it can be set up by an experienced individual, unless you really know what you’re doing (changing CNAME records, etc.) I’d leave setting up Google Apps for Education to your network administrator.
